Android Parse.com push notification crash when app closed or app badge click

Question

Followed the official guide and correctly receive push notification when app is opened. When the app is in background I receive the notification but when clicking on the badge it crash. The same when the app is closed,but I don't receive any notification, it crash and give me the following:

E/com.parse.PushService﹕ The Parse push service cannot start because Parse.initialize has not yet been called. If you call Parse.initialize
 from an Activity's onCreate, that call should instead be in the Application.onCreate. 
Be sure your Application class is registered in your AndroidManifest.xml with the
 android:name property of your <application> tag.

    java.lang.RuntimeException: Unable to start service com.parse.PushService@4263802d0
 with Intent { act=com.google.android.c2dm.intent.RECEIVE flg=0x10 pkg=com.xxxxx.xxxxx 
cmp=com.xxx.xxxxxx/com.parse.PushService (has extras) }: java.lang.RuntimeException: applicationContext is null. 
You must call Parse.initialize(Context) before using the Parse library.

Tried to follow similar post but still not work.

public class Application extends android.app.Application {
    public Application() {
    }
    @Override
    public void onCreate() {
        super.onCreate();
// Initialize the Parse SDK.
        Parse.enableLocalDatastore(this);
        Parse.initialize(this, "dzSJWNKJYWgfPykS90u9TlpWrqCljSsOI", "IEGU9e6mBqZsajxDlI5pFIV");
// Specify an Activity to handle all pushes by default.
        PushService.setDefaultPushCallback(this, Welcome.class);
    }
}

And:

    public class Welcome extends Activity {
Context context;
    SessionManagement session;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_welcome);
        Parse.enableLocalDatastore(this);
        Parse.initialize(this, "dzSJWNKJYWgfrykS90u9TlpWrqCljSsOI", "IEGU9e6mBqZsajxDehmvQ149OILfpFIV");
        // Track app opens.
        ParseAnalytics.trackAppOpened(getIntent());
        ParsePush.subscribeInBackground("Global", new SaveCallback() {
            @Override
            public void done(ParseException e) {
                if (e == null) {
                    Log.d("com.parse.push", "successfully subscribed to the broadcast channel.");
                } else {
                    Log.e("com.parse.push", "failed to subscribe for push", e);
                }
            }
        });

Sorry for eventual rendoundant code, it's result of many attempt. Anyone knows how can I fix it? Any help would be much appreciated.
