How to update firebasemessagingservice to latest version?

I get an error says "error: class, interface, or enum expected" and I found out its from the firebasemessagingservice needs to be updated and I don't know how to do it. Please help.
import android.util.Log;
import com.google.firebase.iid.FirebaseInstanceId;
public class MyFirebaseMessagingService extends FirebaseMessagingService {
#Override
public void onNewToken(String s) {
super.onNewToken(s);
Log.e("NEW_TOKEN",s);
}
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
}
}
private void sendRegistrationToServer(String token) {
//You can implement this method to store the token on your server
//Not required for current project
}
}

you put an extra " } " in your code. remove it and recompile
Correct code:
public class MyFirebaseMessagingService extends FirebaseMessagingService {
#Override
public void onNewToken(String s) {
super.onNewToken(s);
Log.e("NEW_TOKEN",s);
}
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
}
private void sendRegistrationToServer(String token) {
//You can implement this method to store the token on your server
//Not required for current project
}
}

I'm accessing a Pojo class having static method for returning value. When I access this static method in my Splash Screen class(Launcher page), I get a NoClassDefFoundError for that Pojo class. How to avoid this exception without making the method non-static?

This is caused when there is a class file that your code depends on and it is present at compile time but not found at runtime. Look for differences in your build time and runtime classpaths.

Firebase notification is not working when the activity is on the foreground

I don't have problem with the notification when my app is in the background. Can someone tell me why?
This is my manifest.xml:
<uses-permission android:name="android.permission.INTERNET" />
<application
android:name=".CrowdWeather"
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme" >
<activity android:name=".MainActivity" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service
android:name=".FirebaseNotification">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>
</application>
This is the FirebaseNotification.java:
public class FirebaseNotification extends FirebaseMessagingService {
public static final String TAG= "Firebase rocks";
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d("getFrom",remoteMessage.getFrom()+" ");
Log.d("messageData",remoteMessage.getMessageType()+" ");
Log.d("notificationBody",remoteMessage.getNotification().getBody() +" ");
Log.d("total",remoteMessage.getTtl()+" ");
}
}

Unable to retrieve ads form airpush

Got myself newly registered on AirPush. I integrated bundle SDK with my App. When I tested it for the first time, I got a couple of impressions. It also shows 2 impressions on dashboard.
Now I am unable to fetch the impressions. Did contact the developer team but to no avail.
My code of MainActivity goes like this :
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// MMSDK.initialize(this);
// setup a new adView and initialize an adRequest to it.
setupAirPushAdView();
}
#Override
public void onResume() {
super.onResume();
if ((getResources().getConfiguration().screenLayout
& Configuration.SCREENLAYOUT_SIZE_MASK)
== Configuration.SCREENLAYOUT_SIZE_SMALL) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
try {
if (!appStarted) {
setContentView(R.layout.main);
appStarted = true;
}
} catch (Exception e) {
Toast.makeText(this, e.getMessage() + "\n" + e.getClass().toString() + "\n" + e.getLocalizedMessage() + "\n", Toast.LENGTH_LONG).show();
}
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
perform();
}
}, 2000);
}
private void perform() {
setContentView(R.layout.app_home);
if (!appStarted) {
// attachAdView();
attachAirPushAdView();
appStarted = true;
}
...
Other Methods :
private void setupAirPushAdView() {
ma = new MA(this, null, false);
airPushAdView = new AdView(this, AdView.BANNER_TYPE_IN_APP_AD, AdView.PLACEMENT_TYPE_INTERSTITIAL, false, false,
AdView.ANIMATION_TYPE_LEFT_TO_RIGHT);
}
private void attachAirPushAdView() {

outerAdLayout.addView(airPushAdView);

((ChuckApplication) getActivity().getApplication()).setCurrentGame(c) in Fragment

I'm currently studying a trivia style app and I'm using it in a Fragment. If I use Activities instead of Fragments, the code works:
((ChuckApplication)getApplication()).setCurrentGame(c);
But once I cast it for an activity it keeps on getting an error. The code is:
((ChuckApplication)getActivity().getApplication()).setCurrentGame(c);
The whole code is for this fragment is:
public class Activity_Home_Language extends Fragment implements OnClickListener{
Intent intent;

Button btnExam,btnReview;
TextView txtTitle;
View rootView;

btnReview = (Button) rootView.findViewById(R.id.btnReview);
txtTitle = (TextView) rootView.findViewById(R.id.txtTitle);
btnToggle.setOnClickListener(this);
btnExam.setOnClickListener(this);
btnReview.setOnClickListener(this);

The way that you're accessing the Application (or its subclass) from within your Fragment is fine and correct. Since the error you're getting is a ClassCastException, I think that your problem is that you haven't declared your custom Application subclass in the AndroidManifest.xml's application tag. For this reason, calling .getApplication() will actually return an object of type android.app.Application which cannot be typecast to your custom Application class. Perhaps you did do this in your original Activity-based project, but forgot to do so when creating the Fragments-based project?
Example of how to declare your Application subclass in the manifest file:
<application
android:name="com.example.civilserviceexamreviewer.ChuckApplication"
android:icon="..."
android:label="...">
</application>
So, the complete manifest you posted in your question should actually be:
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<application
android:name="com.example.civilserviceexamreviewer.ChuckApplication"
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#android:style/Theme.Black.NoTitleBar.Fullscreen" >
<activity
android:name="com.example.civilserviceexamreviewer.Activity_Splash1"
android:label="#string/app_name"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.example.civilserviceexamreviewer.Activity_Splash2"
android:label="#string/app_name"
