Android: Leaked IntentReceiver exception is being thrown even though I call unregisterReceiver

Question

I don\'t understand why I\'m getting this exception when hitting the back button. I have the IntentReceiver registered in the onCreate method and it is supposed to be unregi

Answer 1

I had the exact same problem. The cause was that I had inadvertently registered the same BroadcastReceiver twice.

Answer 2

This is a Android activity life cycle issue. I am seeing it in a main activity and then testing on device with the back button that goes back to a splash screen.

In the onPause() method.

Unregister the BroadcastReceiver that you created in the onCreate()

In the onRestart() re-register a brand new Broadcast Receiver.

In the activity class you need to keep a record of the Broadcast Receiver as instance data member.

SECOND

I think this also a feature enhancement issue with Android.

Sometimes developer need a broadcast receiver to outlive the activity. For example to understand when certain screen states are available or not. Think about a conversation context of work flow model, which has many states.

THIRD

You can register and unregister broadcast receivers with an activity, but a simple call like isRegistered(BroadcastReceiver) in the Activity class might be very useful.

If you need receivers to live beyond the activity, then I do not the answer, except to silence the warning, by adding unregister(X) in the onDestroy() call. YMMV ;-)

Answer 3

My situation was similar with Mullins, I registered a receiver in both a class and its subclass.

For newbies like me, just toggle a breakpoint at your receiver, then debug your application. If the receiver is something like com.example.main.listener.MyRecevier@421c0100, while the error log in logcat is different from it, such as com.example.main.listener.MyRecevier@4202fb40, with characters after "@" different, surely you registered it twice (or more).

(Above likes a comment under Mullins' answer, actually, I post it here because I can't post comments now.)
