Question

I have on Service that must communicate with an Activity (MyActivity) through a BradcastReceiver. This BroadcastReceiver is declare intosame activity so :

    private class MessaggiReceiver extends BroadcastReceiver {
        public static final String ACTION_RELOAD = "it.android.dev.thecode.ACTION_RELOAD";
        @Override
        public void onReceive(Context arg0, Intent intent) {
            if(intent.getAction().equals(ACTION_RELOAD)){
                leggi_act; //Method of MyActivity
            }
        }

    }

but how must declare into Manifest the brodcast contained within the MyActivity ? I used this code with it.android.dev.thecode.MyActivity.MessaggiReceiver

<receiver android:name="it.android.dev.thecode.MyActivity.MessaggiReceiver">
            <intent-filter>
                <action android:name="it.android.dev.thecode.ACTION_RELOAD"></action>
            </intent-filter>
</receiver>

but is wrong then I used this code with it.android.dev.thecode.myactivity$MessaggiReceiver

<receiver android:name="it.android.dev.thecode.MyActivity$MessaggiReceiver">
                <intent-filter>
                    <action android:name="it.android.dev.thecode.ACTION_RELOAD"></action>
                </intent-filter>
    </receiver>

Thanks

You don’t need to register a broadcast receiver in your manifest, instead register it by code in your activity’s onResume. Don’t forget to unregister in onPause to avoid any leaks.

@Override
public void onResume() {
   registerReceiver(mMessageReceiver,
       new IntentFilter("it.android.dev.thecode.ACTION_RELOAD"));
}

@Override
public void onPause() {
   unregisterReceiver(mMessageReceiver);
}

private BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
  @Override
  public void onReceive(Context context, Intent intent) {
    Log.d("receiver", "Got broadcast: " + intent.getAction());
  }
};
