Can i start an android service without activity or GUI?

My target Android is 4.1.2. I created an simple android service which will show Toast on boot. But this application should not have any GUI. I was success running this service only from an activity which show GUI on start.

public class MyServices extends Service {
private MediaRecorder recorder = null;
@Override
public IBinder onBind(Intent intent) {

    return null;

}
public int onStartCommand(Intent intent, int flags, int StartId)
{

    Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show();

}
}

You can start this service from RebootReceiver but As of Android 3.0 the user needs to have started the application at least once before your application can receive android.intent.action.BOOT_COMPLETED events.

Reboot Receiver -> Android BroadcastReceiver on startup - keep running when Activity is in Background

First you have to create a receiver:

public class BootCompletedReceiver extends BroadcastReceiver {

final static String TAG = "BootCompletedReceiver";

@Override
public void onReceive(Context context, Intent arg1) {
    Log.w(TAG, "starting service...");
    context.startService(new Intent(context, MyServices.class));
}

}

Then add permission to your AndroidManifest.xml

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

and register intent receiver:

<receiver android:name=".BootCompletedReceiver" >
<intent-filter>
    <action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>

After this is done, your application (Application class) will run along with services, but no Activities, don't put your application on SD card (APP2SD or something like that), because it has to reside in the main memory to be available right after the boot is completed.
