Is there an method in Android which equivalent to applicationDidBecomeActive?

Issue

I try to use onStart() or onResume() at first. However, there are two drawbacks to use them.

1, If I start another activity and dismiss it later, as follow. (Kind of like modal present a new viewcontroller and then dismiss it)

private void dismiss() {
   Intent intent = new Intent();
   intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
   intent.setClass(this, MainActivity.class);
   startActivity(intent);
   finish();
}

onResume() will still be called

2, I can't reuse the same login in other activity.

Therefore, I wonder if there is an method in Android is exactly the same as - (void)applicationWillResignActive:(UIApplication *)application in Android

Solution

If you bring the MainActivity to the front using your dismiss() code, you can detect this in MainActivity.onNewIntent() like this:

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    if ((intent & Intent.FLAG_ACTIVITY_REORDER_TO_FRONT) != 0) {
        // I've been brought to the FRONT by another activity
    }
}

Does this help? I'm not 100% sure I understand what you want.
