I’m creating a quiz app with SQL and Firebase. First screens are SignUp/in activities, and after user is signed he is redirected to a splash screen which automatically navigates to PlayActivity. In play activity I wanted to handle the onBackPressedMethod, so that the user will close the game with the following code:
@Override
public void onBackPressed() {
if (backPressedTime + 2000 > System.currentTimeMillis()) {
new AlertDialog.Builder(this)
.setTitle("Do you want to exit?")
.setNegativeButton("No", null)
.setPositiveButton("Yes", (dialog, which) -> {
setResult(RESULT_OK, new Intent().putExtra("Exit", true));
System.exit(0);
}).create().show();
}else {
Toast.makeText(this, "Press Again to Exit", Toast.LENGTH_SHORT).show();
}
backPressedTime = System.currentTimeMillis();
}
The problem is, that after pressing the Yes button in the alert dialog, user is redirected to a previous SignUp activity, instead of exiting the game?
How can I fix this?
>Solution :
You need to call finishAffinity() in your SignUpActivity before you navigate to PlayActivity. This will remove the first Activity (and any below it) from the stack.
