Switching Activities in Android Studio: Android Programming

Create and launch a second Android activity. Covers Intent, startActivity(), finish(), and the activity stack.
For tutorial on creating a button, see • Creating a Button: And...
Initial setup:
--------------------
Have project with initial activity and button for Toast
Create new activity: SecondActivity
--------------------
Show .xml, .java, and manifest.
Launch activity:
--------------------
startActivity(new Intent( [Current Activity's 'this'], [New Activity's Java].class));
Encapsulate launching
--------------------
Intent i = SecondClass.makeIntent(this)
startActivity();
Activity Stack
--------------------
Loading an Activity pushes it on the Activity Stack
Pressing back button pops stack:
destroys this activity, returns to previous activity.
New Button runs activity's finish() method pops it in code.
Must use correctly to have good activity stack.
If you instead startActivity() back to the first one, you make a loop.
Can move on and kill current activity:
--------------------
startActivity(...);
finish();
Troubleshooting:
--------------------
Demonstrate what happens with the activity being in the manifest.

Given how fragmented Android's versions are against each other, it's so relieving to have these concise video that just get to the point straight away. Can't thank you enough for providing these tutorials!

hi Brian, what'ss the diference between "finish()" a SecondActivity and using "android:parentActivityName" in Manifest. My problem is that I have a filter in MainActivity and when i get back from SecondActivity I lost that filter.

Great video

[@hamzadaiz9002]

Thx brooo ^^ You healp me to resolve that prob

[@Jab_hutt]

Somewhere at 8:00+ lost it completely. As I understand that's due to lack of experience, although I am a moderate programmer, but such things bug me out always. You can't see any logic of what's going on completely, basically just remember it and roll with it, that's how it works.

[@stationHQ]

@Suresh Mca, it always helps to be precise or clear when you express a negative opinion about anything in life.
What do you mean by "not good"? Is it the contents of the tutorial or the quality of the video used to present the tutorial? Any suggestions as to how to make it "good" according to your standards?
