Answer 1

Just try on jelly on this is working for me :

             broadcastReceiver = new BroadcastReceiver() {//global BroadcastReceiver
            @Override
            public void onReceive(Context context, Intent intent) {

                String action = intent.getAction();
                if(action.equals("android.intent.action.MEDIA_BUTTON")){
                    Log.e("test", "ok");
                }
            };

Intent :

        IntentFilter intentfilterTime = null;
        intentfilterTime = new IntentFilter();  
        intentfilterTime.addAction("android.intent.action.MEDIA_BUTTON");
        registerReceiver(broadcastReceiver, intentfilterTime);

Test from service with media button of Widgetsoid (who emulate BT media buttons). All is working.

It looks like your broadcast receiver is an inner class to your service? If so, make your broadcast receiver static and in the manifest do this:

<receiver android:name="MyOuterClass$MediaButtonIntentReceiver" android:enabled="true">
    <intent-filter android:priority="2147483647" >
        <action android:name="android.intent.action.MEDIA_BUTTON" />
    </intent-filter>
</receiver>

In Android 3.0+ you must use registerMediaButtonEventReceiver to register the receiver. This uses the AndroidManifest for the IntentFilter. The reason it works in 2.x is because you were registering it with this.registerReceiver() which registered the receiver without the AndroidManifest.
