How to open your application on top of other applications by event (even if by timer)?

Answer 1

This is a very bad idea, if you want to draw the user's attention to the application, then use notifications, but if you still need to move the application to the foreground, then add to the manifest:

<intent-filter>
 <action android:name="intent.bring.to.front" />
 <category android:name="android.intent.category.DEFAULT" />
</intent-filter>

and in the right place call:

Intent intent = new Intent("intent.bring.to.front");
intent.setComponent(new ComponentName(context.getPackageName(), MainActivity.class.getName()));
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.getApplicationContext().startActivity(intent);

but again, don't do that.
