Close application and launch home screen on Android

Question

I have two different activities. The first launches the second one. In the second activity, I call System.exit(0) in order to force the application to close, bu

Answer 1

I use this:

1) The parent activity call the secondary activity with the method "startActivityForResult"

2) In the secondary activity when is closing:

int exitCode = 1; // Select the number you want
setResult(exitCode);
finish();

3) And in the parent activity override the method "onActivityResult":

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    int exitCode = 1;
    if(resultCode == exitCode) {
        super.setResult(exitCode); // use this if you have more than 2 activities
        finish();
    }
}

This works fine for me.
