Broadcast receiver for incoming messages

Question

If I have an inner class that extends BroadcastReceiver within my Service class, should I care about synchronization, when the BroadcastReceiver class reads/writes to objects from the Service class? Or to put it in another way: Are BroadcastReceivers onReceive() Methods started in an extra thread?

Answer 1

No by default all of the components use the same thread/process unless you specifically request the android system to use a separate process using the android:process attribute or create your own threads.

Also this question is same as yours.
