How to design a location tracking App using GPS in Android Studio - source code?
HTML-код
- Опубликовано: 6 сен 2024
- This video shows the steps to create an App which uses Google Map to give the precise location of your phone. This app can be used to track your current position. In the initial part of the video it shows how to create API Key to have the access of the google Map.
This custom app works offline based on GPS and you do not need internet connection to get your current location.
For 2nd part of this tutorial please refer to the below video: • How to track your loca...

We will be glad to hear from you regarding any query, suggestions or appreciations at: programmerworld1990@gmail.com
I am pasting the main method code below (for complete class please contact):
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
// Add a marker in Sydney and move the camera
LatLng sydney = new LatLng(-34, 151);
mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
locationListener = new LocationListener() {
@Override
public void onLocationChanged(Location location) {
try {
latLng = new LatLng(location.getLatitude(), location.getLongitude());
mMap.addMarker(new MarkerOptions().position(latLng).title("My Current Position"));
mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
}
catch (SecurityException e){
e.printStackTrace();
}
}
@Override
public void onStatusChanged(String s, int i, Bundle bundle) {
}
@Override
public void onProviderEnabled(String s) {
}
@Override
public void onProviderDisabled(String s) {
}
};
locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
try {
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, MIN_UPDATE_TIME, MIN_UPDATES_DISTANCE, locationListener);
}

Sir, you really save my life. God bless you and your family
The marker shows up but not the actual google map. Just shows a red marker on an empty page.
That is because your maps has not been downloaded in your App. This usually happens when there is network issues and internet is not accessible or it is very slow. The marker shows up because it is independent of network. It uses phone's gps to get the coarse location.
I will recommend to check your mobile data or wifi in your phone. If you are trying on the emulator then please check if other Apps, such as Play Store, is able to access the internet. For emulator sometimes you may have to do proxy settings if you are in a LAN environment. You can do the proxy settings from the Android Studio->Settings window. Just search for http in the settings window.
Hope above details helps in resolving the issue.
Good Luck

@@ProgrammerWorld The map and marker are now showing but the marker is in GooglePlex , USA. Is this because I am using an emulator and not a real phone?
@@YSNR.25 Yes, exactly. It shows California USA, because you are using emulator. Emulator can't access your location information from your laptop as GPS functionality is not available and Network location information is not shared by the laptop's OS. So, it takes the default location to be at Google center in US.
In real phone it should work as the App will have access to both GPS (Coarse) location and Network (Fine) Location.

10:01 Once I start to type the exact same code in line 29 & 30, it show ActivityCompat is not cannot be resolved. Could you help me?
For ActivityCompat, you may have to import the following package in your java code:
import android.support.v4.app.ActivityCompat;
In Android Studio, it should automatically import the packages used in the code. However if it is not doing then you can try adding it manually. You can also refer to the below page where I have shared complete source code shown in this tutorial:

Hope it helps. Good luck!
Hi thanks for the video works awersome!!! Hi just comment out the following lines your code to get the Sydney pointer off the map
// Add a marker in Sydney and move the camera
//LatLng sydney = new LatLng(-34, 151);
//mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
//mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
sir i would like to know can we make it run in background always so that we can register a number in it and we should be able to send the location every 1 hr that's 24 hrs a day 24 messages per day..
it would be useful right??
Yes, sure that is possible. You should watch my below videos to get the steps on creating foreground services which keeps on running in background even when the App is closed.

Great work done by this guy
according to you how we could be good in making apps from beginners to expert. what are the sources you recommend us to understand the complexity of making the apps and sites
This is very subjective question. However, in simple words:
1. Take a basic tutorial from some trainer.
2. Ensure you know the programming (any language: C/C++, Java).
3. Then practice - you can refer to my channel for practice exercise.
Also, you can refer to my below webpage for lots of practice exercise on Android App development:

This works, if it's in the main activity, but if I put the same code into a service it starts bugging out after restarting the phone when the service is set boot with the device. Any ideas? If the code is in the main activity, it will call on status changed then I have 1 toast to confirm this happened then it will gather location every now and then. If it's in the service the location gets gathered, it will show the toast MULTIPLE times, then it gathers the location? I'm expecting 1 toast then gathering location. It can toast everytime after it polls the location, but it shouldn't be giving more than 1 toast per location grab. As stated, when the code is in the main activity it works as expected 1 toast per 1 location grab. I need ideas.
Most likely, when the code is in the service class, it is repeatedly getting called due to frequent call to service class by the Android OS. Now, since there is no way for the class to know whether the Location has changed from the previous known location, so probably it calls onLocationChanged every time the service class is called.
Probably, one way to avoid this would be by updating the last location information in the app using the FusedLocationProviderClient API. Below webpages may help:

I just one question sir how can I show the marker quicker because sometime when i open the app it takes time to show the marker on the map thankyou for this tutorial
mMap.addMarker method call is responsible to add the markers in the maps. Now, once the Map is loaded and ready in the App (calls onMapReady method) then only the marker can be added. To speed up the loading, you can check for this method in the onCreate method of your App. It may help.

Hi. I'm just starting to write programs in the android studio and I have already found one of your videos for which thank you very much. I have a question. is it possible to set the default distance from the marker of our position in this script? do you have to zoom in from the continent and countries each time? I would like to enter the location in my future application, but I would like it to immediately show my position in the area, e.g. 50km from me. will it be difficult to implement? Regards.
In the moveCamera method's parameter, please use either CameraUpdateFactory.newLatLngBounds or CameraUpdateFactory.newLatLngZoom to set the camera view at a particular zoom level.
In the code shown in this video, below line is used which takes default zoom level at the given lat and lng:
mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));

@@ProgrammerWorld thx man ! Program work but in my position i have many markers. Every 1 second app create new one. Maybe i can change some code, and new Mark show when i change my position , but not than 1 second. Have you some advice for that? What do you think, maybe i can add Button , and when i click on it , program refresh position? Or maybe its possible on your code and i dont know how 😁
Change below variables in your code:
private final long MIN_TIME = 1000; // 1 second
private final long MIN_DIST = 5; // 5 Meters
The markers is placed when either of above is true. That is, either every 1 second or every 5 meters distance change.

Conceptually it should work as the tracking mechanism remains same. However, I have never tried myself to map the location based on Bluetooth beacon sensor data.
Nice
Hii sir, I have used the same code to create this app but it keeps stopping as soon as I open it.......please help me why is it happening?
Try to debug and check for the reason of crash. Most likely the onCreate method is crashing. Better put a try-catch for smooth handling. Also, crashes during the start is most of the times due to null pointer exceptions. Please debug and check.

hello sir... my location showing Sydney...my current location not showing...
Sydney is the default location. If your current location is not getting updated, then it means either the location services (GPS or network) is not working in your phone or in your App's code it is not reaching the location listener part of the code. I will suggest to debug the code and check the flow of your code.

You will need a database to store user credentials and then match it against the login page. So, the login page will depend on the db. There are many videos on various database, such as Firebase and MS SQL, on my website:

Hello Sir. I am using your tutorial to make a system which tracks the movement of a vehicle. In your tutorial, you have used marker to show the path right? What can I do to make it a straight line?
Also, I would like to use external GPS coordinates that are received to my phone by bluetooth. How can I do this?
Your help is highly appreciated.
Regards.
For getting it in straight continuous line you can put the marker more frequently however it may not appear very nice. Will check on how to get aesthetically appealing tracking in map.
For 2nd question, you should watch my below video which shows steps on how to pass/send the latitude and longitude coordinates to another phone through SMS. Of course, you will have to adapt it for transfer of data over Bluetooth:

Your code looks good and it should work at your end as well. Just a quick question, have you defined the required permission (Access to coarse and fine location) in your App's manifest file? I think that could be the reason for your SMS sending and reading permission issue. If possible, can you please share your manifest file as well?

umm..... for me it doesnt get updated on my mobile phone the marker is still in sydney no matter i give location access or i reinstall the app.PS: my internet connections are good
Then please debug the code and check where it is failing.
Concept of this App is very simple. You get your position based on gps data and network access to your App. That translates to latitude and longitude values. And finally, marker is moved based on these updated values.
Please can you help me? I do everything and it doesn't trigger the app, it crashes.
Debug your code, put a break point and see where the App crashes. Also try to wrap the part of the code using try-catch to better handle the exceptions thrown. Let us know the exception the App is throwing (when it crashes) and we will look into the issue.

Hi I installed the app and it is working , but there is one problme if I am zoom in I am getting many locations not only one location of mine....can you help me out with that.
Because in the code, I have just shown to add markers. I am not clearing them up for every location update. So, whichever points you move to, those will show on the map as static markers.
To refresh it, you will have to clear the map on the update of location listener before adding the marker. This way the map will just show your live location with the marker.

hello sir the application is working but whenever it changes the location new pinpoint appear then the previous pinpoints will remain. how can i remove those previous pinpoints and only have the newest one. The other problem is, we tried this on 4 different phones, for the 2 phones it run smoothly it can locate the exact location no problem at all (just the pinpoint) but for the other 2 it cant locate its location. and for the last one, is it possible to draw an object in the map? for example a circle with a pin point located at the center. Thank you!!!!!
- how can i remove those previous pinpoints and only have the newest one.
Just add mMap.clear() to remove all the markers before adding the new marker.
- The other problem is, we tried this on 4 different phones, for the 2 phones it run smoothly it can locate the exact location no problem at all (just the pinpoint) but for the other 2 it cant locate its location. and for the last one
Just ensure that GPS and Data network is ON and location access permissions (Coarse and Fine) both are granted to the App in the phone. Also, sometimes in some phones there may be restriction on using certain permissions for the user Apps. Just check that by going to Settings->Apps->Permission. A quick fix for this will be to just reinstall the App after removing the App (including the App data).
- is it possible to draw an object in the map? for example a circle with the pin location in the center of the circle.
There are lots of properties of markers which allows to customize the shape, color, size, etc. of the marker. As of now we do not have a video to show this but below page will help you with this:

Hi bro, I want to trace the geolocation of some devices which are locally connected via ethernet mode. Is there any free API to embed this feature?
Sir how can we retrieve location from firebase ....
Which is already sent to firebase through raspberry pi using GPS module
Hi,
It can be simply done by getting the instance of the Firebase database and then reading the data. It has been explained in the below article with source code (though a bit complex). I will try to make a simple video on this topic and post it here when I get time.
www.androidauthority.com/create-a-gps-tracking-application-with-firebase-realtime-databse-844343/
its not showing my current location instead showing marker in sydney
If your code is correct, it should work. However, in emulator it may show your position as California irrespective of your current position.
But in real phone it will work. Though it may take some time on first time run as it will need to download the map.
Also, please ensure that the access to coarse and fine location (GPS and network data location) is granted as it will be used to update your location.
i am getting a blank page with the word google at the bottom and no map
Please ensure that network access is there on the phone which is needed to download the map in the first time.

Is it possible to add a schedule of locations where the person goes and get the notification if the person is out of that routine location?
Yes, it will be possible.
Based on the latitude and longitude information, you can keep a check. The moment the current location of device goes out of bound of the allowed latitude and longitude, then trigger the alarm.

Hello , to actually see the change in Location would I just have to move to a different location with my laptop and then re-run the app? Also i dont know why it automatically shows california location when I run the app, any reason for that ? Thank you
This App cannot be tested on the laptop (Emulator) because the location sensors such as GPS is not emulated in the emulator. To test it please use a real phone or device.
The location in an emulator shows California because by default emulator takes the Google's headquarter as the location of the AVD.

Hello sir I have doubt that if we want to track other phone number to help then whether the person should need tracking app or the one who want to help need the app
Dear Chandana,
The person who wants to share his location will need this App installed on his phone and not the one who wants to help.
Along with the location tracking App, you can see my other video (link below) which shows how you can send automatic SMSes to the another person. So, the person whose phone needs to be tracked should have location App with SMS functionality so that he can send the latitude and longtitude information to another person who wants to help.
ruclips.net/video/pajvuBZc2WA/видео.html
Its working on the avd,bt it not showing location on the mobile.why?
Check if your App has access to location information from your phone. It should have access to both GPS info and precise location based on your mobile signal.
You can check this by going to Apps permissions in your Android phone setting.
Let me know if you continue to face issues.
Is it possible to make gps car's vector and track at random point of a drive their statistics like app ?
Yes, it is possible. In the App code what I have shown is that you will get latitude and longitude of the position of your GPS device (Android phone). You can collect these information like latitude and longitude at different time stamps and then create a statistics out of it.
In the video I have shown to update latitude and longitude information on the map. But for your requirement please store them in variables and then various statistics can be drawn from them.
I want to get the crime record for the particular location, how can we code for that so we can get the crime data for that individual location while we enter
For your requirement, the crime record for the locations should be stored in a database. Then that database values should be accessed and plotted on the map. Something similar to what is shown in the below link:

hi bro how are you?can we use offline google map for get current location?
Yes, I think you can work in offline mode if you have used the location tracking based on GPS also along with network in your App code.
However, for the first launch of your App network would be needed to get the Maps configured in your custom App. Accessing pre-saved google maps may not be possible as your custom maps will not have access to the google map App data on your Android phone.
Hiii i want to update location even when app is in background ???? So hw cn i do it
You can use the foreground or background process to run it in the background.
I do not have any video for background process yet.
However, for foreground process you can refer to the below videos:

my application keeps "stop work" what can i do
There are 2 options:
Either debug your code and check at which line the code is breaking. To debug you should start the emulator in debug mode and put break point at the start of your Java code file.
Else 2nd option is encapsulate your code in various try catch and check the exception thrown in the catch part. Then you can program the code to take appropriate action in case of exceptions thrown.
In general my guess is in your code it is not able to get the GPS reading and hence while reading latitude and longitude it is failing. However, of course I can't be sure unless we debug the code.
Hello i cant run app, the first time i run it into the emulator i getting an error trouble with google play services
Then it implies that in emulator, it has issues to reach Google. Either due to network issues or your Google login account issues (incorrect login details). This App may be requesting for Google services to access Google Maps, though I am not sure. In my phone/emulator, Google Play services are logged in so I have not observed such issues.

sir when i started the app for the first tym it just showing the white screen with google icon on left bottom my internet speed is 6-7 mbps what should i do
and how much it will take to download the map
It should not take more than 2-3 minutes. If it is taking more than 5 minutes then something is wrong. Your App is not able to connect to the Google Map over internet. Don't wait further.

Hello brother I had a doubt that how we can track the location when the user doesn't accept our request.... If the user accepts the location doesn't share.... If the user doesn't accept the location need to be share..... Kindly tell how would to be create this....
Hi Subair,
If the user does not accepts the request to share the location to your App, then there is no way to get that information. Of course there are ways you can get the developer rights of the phone and then hack the phone to get the location information. But google is very sensitive to these approaches and it is is highly discouraged to try such approaches. Also, it is beyond the scope of this video tutorial.
If the user accepts to share the location info of his phone to your custom App, then voila you have all the information. Please watch 2nd edition of this tutorial at: ruclips.net/video/FknRti6n_F8/видео.html . Here, I have also shown that once you have the location information how you can send it or share it with someone else over SMS.
I followed this code, but it is still stating that I am in the location provided on the video whereas I am based in Maryland.
So, does your location shows Sydney or California? .... If it is Sydney then it means your location listener is not working (either gps and network is not providing updated location or your App is not getting location updates from these sensors due to issues like permission not granted for the location access).
Else if your location is showing California then it means that you running your App on the emulator. On emulator, as I have explained in another comment, sometimes the location information is not passed to emulator from your PC network.
See my reply to Saish Sawant's comment around 2 weeks back for details on this.

Hi,
I did not show in my code to remove the previous markers because I liked the trail mark it showed for all the points my phone has reached.
However, if you want to remove the markers in your map, you can easily use the CLEAR method for your google map object. Try the below command in your Java code just before adding the new Marker. It should clean up all your previous Markers from the Map:
mMap.clear();

4GB RAM should be fine for Android Studio. It should work. But I think you will face issues while running emulator. So, I will suggest if you want to use Studio and emulator both simultaneously then please upgrade to at least 8GB RAM. In 16GB RAM, the performance will be best. But check your budget. Try to upgrade to at least 8GB RAM.

How can we send the location of the person to the registered phone number without internet
Hi,
I think the only other way (without internet) to share your location details would be through sms. Get the latitude and longitude information using GPS in the map and send it through SMS to other person. Of course for this one will need access to SMS service in the location app. This can be done by updating manifest file.
Will try to make a video on this concept when I get time and share it on my channel.
Hello Everyone i had the same error. of the marker not showing my location change LocationManager.GPS_PROVIDER to LocationManager.NETWORK_PROVIDER
first time, the app didn t show me my real location, it was only the sydney mark, but now with NETWORK_PROVIDER it s working. u re a life saver. thx!
You can try both NETWORK_PROVIDER and GPS_PROVIDER in your code by implementing it as below:
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, MIN_TIME, MIN_DIST, locationListener);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, MIN_TIME, MIN_DIST, locationListener);
This will increase the chance of getting the exact location from both the sources - GPS and Network.
However, just using GPS_PROVIDER should have worked on your phone. The only caveat is that you will have to ensure that GPS Satellite is clearly visible to your phone. For that you may have to go in open area for few minutes.
i had a doubt that how can i connect a tracker to this app to track the vehicle which was integrated with a tracker.do we have any special key to connect with it?

For tracking, the other part is to send this information to some server and receive it on another device (smartphone). You can use Firebase database provided by Google for free. Otherwise you can have your custom servers where you can store your location details and read it from 2nd phone. I will try to make a video on this and publish it when I get time.

Create the location tracking App as shown in this video. Then capture the latitude and longitude of the phone's location during live movement.
Then Transfer the latitude and longitude information through another App or SMS facility or store it in some database which can be accessed from another device. This part of concept is not shown in my video. We will try to do it if we get time.
I'm interested in this too !
@@lowjl6046 Hello,
You can refer to the below video in which I have shown how to send SMS pro-grammatically directly from your App.
ruclips.net/video/pajvuBZc2WA/видео.html
This concept can be used to send the the details of you location like latitude and longitude to another phone and a log can be created. Of course SMS charges can be applied by your service provider.
In the receiving phone, create an App which reads the SMS messages as shown in my below video:
ruclips.net/video/K9IloJ_66WI/видео.html
Once you have that data in another phone through SMS then plot those points on the Map. And voila, you will see the location of first phone in 2nd phone.

hi may i know what are the specific specs of the phone needed?
There is no specific requirement of the phone. Only thing you should ensure is that minimum API level selected in your phone is supported by your Android OS. For example: for API 26, Android 8.0 (Oreo) and above is needed as shown in my video at 1.01 min. Similarly, for API 21, Android 5.0 (Lollipop) and above is needed.
@@ProgrammerWorld sorry this is my first time creating this,i am still confused and I only have a budget for a phone that has 2gb ram, 16rom and kitkat android. will that be ok?
Hi Kyra,
For the location tracking App, you do not need very high specification phone. I think the phone specification which you have mentioned should suffice for this App. Regarding the OS, Android kitkat is Android version 4.4 which support minimum API level 19. So, please make sure that you select the API level 19 while creating your App in the Android Studio's initial setup page for the App. The only difference is that with each API level change some the commands and APIs is modified by google team. So, minor adaptation of code is required with the change in API level.
Moreover, if interested you can watch my 2nd version of location tracking App using the below link: ruclips.net/video/FknRti6n_F8/видео.html. This video also covers how you can send your location info automatically over SMS to another phone.

Please check whether your App has the permission to access the Location in your Phone. You can check this in your phone by going to Setting->Apps->Permission->Location Permissions.
If the location permissions are not provided please enable it. Also, there are 2 types of location access - Fine and Coarse location info.
Coarse uses only GPS data to get the location info so the location coordinates (latitude and longitude) may not be very precise.
Fine will use combination of GPS and Network data and will, hence, provide more precise and accurate location information of your phone. Both of these are explained in the source code provided in the below link:

@@ayushisinghal553 For your requirement, the crime record for the locations should be stored in a database. Then that database values should be accessed and plotted on the map. Something similar to what is shown in the below link:

What is the api link
Hi,
From API link, if you referring to Google Maps API key, then it is the link to the encryption key used to sign the APK for Google Maps based APIs. Also, You need a different API key for each encryption key, including the release key that is used to sign the APK for publishing.
You can define the keys for the debug and release targets in src/debug/ and src/release/.
I hope the above answers your query. However, if you meant something else then please let me know. Also, the complete source of this tutorial can be found in the below link:
