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 solved a similar problem: MainActivity starts BrowserActivity, and I need to close the app, when user press Back in BrowserActivity - not to return in MainActivity. So, in MainActivity:

public class MainActivity extends AppCompatActivity {
    private static final String TAG = "sm500_Rmt.MainActivity";
    private boolean m_IsBrowserStarted = false;

and then, in OnResume:

    @Override
protected void onResume() {
    super.onResume();
    if(m_IsBrowserStarted) {
        Log.w(TAG, "onResume, but it's return from browser, just exit!");
        finish();
        return;
    }
    Log.w(TAG, "onResume");

... then continue OnResume. And, when start BrowserActivity:

    Intent intent = new Intent(this, BrowserActivity.class);
    intent.putExtra(getString(R.string.IPAddr), ip);
    startActivity(intent);
    m_IsBrowserStarted = true;

And it looks like it works good! :-)
