Receiver not registered exception error?

The root of your problem is located here:

 unregisterReceiver(batteryNotifyReceiver);

If the receiver was already unregistered (probably in the code that you didn't include in this post) or was not registered, then call to unregisterReceiver throws IllegalArgumentException. In your case you need to just put special try/catch for this exception and ignore it (assuming you can't or don't want to control number of times you call unregisterReceiver on the same recevier).

Be careful, when you register by

LocalBroadcastManager.getInstance(this).registerReceiver()

you can't unregister by

 unregisterReceiver()

you must use

LocalBroadcastManager.getInstance(this).unregisterReceiver()

or app will crash, log as follow:

Use this code everywhere for unregisterReceiver:

if (batteryNotifyReceiver != null) {    unregisterReceiver(batteryNotifyReceiver);    batteryNotifyReceiver = null;}
