Android BroadcastReceiver onReceive() called twice on android 4.0

Question

I faced to one problem on android 4.0.3 (on 4.1.2 it works fine). I have in my Activity BroadcastReceiver. When I send a broadcast, method onReceive() called always twice. P

Answer 1

I have just had this problem and I found a solution that wasn't mentioned in any of the existed answers, so I would like to share it.

I register the BroadcastReceiver just once in onCreate

However, I was registering it like this:

LocalBroadcastManager.getInstance(this).registerReceiver(new MyBroadcastReceiver(), mStatusIntentFilter);

In other words, I was constructing the boradcastReceiver instance inside the registerReceiver call.

But when I construct the BroadcastReceiver in a separate statement the problem was solved. Like this:

MyBroadcastReceiver myBroadcastReceiver = new MyBroadcastReceiver();

LocalBroadcastManager.getInstance(this).registerReceiver(myBroadcastReceiver , mStatusIntentFilter);

Very weird workaround, maybe it's a bug that will be fixed later.

Answer 2

Usually onReceive is being called twice since people are registering the broadcast in 2 locations, Most likely you are registering in your onCreate and in your onResume. (Choose one spot to register).

Although you might have done it probably a dozen of times - it is always recommended to take another glance at the Activity Life Cycle.

Answer 3

I was calling sendBroadcast(intent) multiple times in my Service class

Removing one of them fixed the problem.
