🚨 Important Tip for Viewers 🚨: For a smoother experience using the Android Calculator app, consider this tweak. In the 'Main.java' file, within the 'MainActivity' class, locate the line 'double firstNum;' and modify it to 'double firstNum = 0;'. This adjustment helps prevent potential errors when clicking 'equal' before any operation. Your feedback is valuable!
issue still existing to fix it you should add this code to equal.setOnClickListener: if (operation == null) { Toast.makeText(MainActivity.this, "No operation selected", Toast.LENGTH_SHORT).show(); return; }
That's a great suggestion! If the issue persists, adding that code snippet to the `equal.setOnClickListener` could help. Alternatively, you could set a default operation like addition ('+') by replacing 'String operation;' with 'String operation = "+";' in the code. This way, you handle the problem by ensuring there's always an operation selected before clicking 'equal'. Hope this helps!
Hi sir, Greetings of the day. This is to inform you that the button text not showing, Also one other problem (Speakale text not present) sir please help to resolve it.
To help you with the errors you're facing, could you provide more details? Specifically, what error messages are you seeing with your TextView, getText, and setVisibility methods? Additionally, sharing the relevant parts of your code where these issues are occurring would be very helpful. Looking forward to your response so I can assist you further!
Thank you for your tutorial. The only question which is beside from your tutorial concept. If you could answer i would appreciate. When I press dot on my keyboard the dot (point) appears on number field but calculation crashes and the app exits. What could be the correct way of this ?
Hi Elçin, I apologize for the delay in my response to your comment. I'm sorry that I wasn't able to respond to your request in a timely manner. I'm sorry to hear that you're facing an issue with this project. It is possible that the error occurred because you clicked the equals sign without first selecting a mathematical operation. Make sure to choose the appropriate operation before clicking the equals sign to avoid any errors. One suggestion I can offer is to try using a try-catch block to identify and isolate the error and logging the exception to provide more visibility into the error. If you're still having trouble after trying this technique, you can contact me directly at my email: Bob.TechWithBob@gmail.com However, please note that due to some pressing commitments, I may not be able to respond immediately. Thank you for your understanding, and I hope we can resolve this issue together.

I'm glad to hear that everything else is working fine! However, I'm not quite understanding the issue with the color of the digits and signs.

Could you provide more details or clarify the specific part where you're facing this issue? Once I have more information, I'll do my best to help you resolve it as quickly as possible.
If the texts on the buttons are not visible, you can try adding @color/black in buttons style (Button1 & Button2) in themes.xml. This might help in making the text visible. Give it a try and let me know if it resolves the issue. If you have any other questions or if this doesn't work, feel free to ask, and I'll do my best to assist you further!

I'm not sure of the exact version of Android Studio used, but it's likely that it was Android Studio Electric Eel | 2022.1.1 Patch 2 (February 2023).
