I've been trying to figure out how to add ads to my project for days. I'm hoping that you guys can show me what to do. I am trying to ad the ad after the first round (First time the player dies) After they close the ad; it will allow them to play again.
No ads are appearing and I am getting errors such as:

My classes:
AndroidLauncher
package com.JrodManU.LaserJumper.android;
import android.os.Bundle;
import com.badlogic.gdx.backends.android.AndroidApplication;
import com.badlogic.gdx.backends.android.AndroidApplicationConfiguration;

import com.JrodManU.LaserJumper.LaserJumper;
public class AndroidLauncher extends AndroidApplication implements GameEventListener {
Ad ad = new Ad();
@Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
initialize(new LaserJumper(this), config);
}
@Override
public void showAd() {
ad.showAd();
}
@Override
public void loadAd() {
ad.loadAd();
}
@Override
public boolean isShowing() {
return ad.isShowing();
}
@Override
public boolean isLoaded() {
return ad.isLoaded();
}
}
InGameScreen (Screen class)
package com.JrodManU.LaserJumper.screens;
import com.JrodManU.LaserJumper.LaserJumper;
public class InGameScreen implements Screen {
LaserJumper game;
boolean firstTime;
public InGameScreen(LaserJumper game) {
this.game = game;
game.loadAd();
firstTime = true;
}
@Override
public void render(float delta) {
generalUpdate();
}
private void generalUpdate() {
if(playerDied) {
if(firstTime && game.isLoaded()) {
System.out.println("hi");
game.showAd();
firstTime = false;
while(game.isShowing()) {
//Waiting for the ad to go away..
}
}
}
Ad
package com.JrodManU.LaserJumper.android;
import com.JrodManU.LaserJumper.GameEventListener;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.InterstitialAd;
import com.google.android.gms.ads.AdListener;
import android.app.Activity;
import android.os.Bundle;
public class Ad extends Activity implements GameEventListener{
private InterstitialAd mInterstitialAd;
public static boolean showing;
public static boolean loaded;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mInterstitialAd = new InterstitialAd(this);
mInterstitialAd.setAdUnitId("*****");
AdRequest.Builder adRequestBuilder = new AdRequest.Builder();
adRequestBuilder.addTestDevice(AdRequest.DEVICE_ID_EMULATOR);
mInterstitialAd.setAdListener(new AdListener() {
@Override
public void onAdClosed() {
showing = false;
}
@Override
public void onAdLoaded() {
loaded = true;
}
});
}
public void showAd() {
if (mInterstitialAd.isLoaded()) {
mInterstitialAd.show();
showing = true;
}
}
public void loadAd() {

mInterstitialAd.loadAd(adRequestBuilder.build());
}
public boolean isShowing() {
if(showing) {
return true;
} else {
return false;
}
}
public boolean isLoaded() {
if(loaded) {
return true;
} else {

}
}
}
LaserJumper (main class)
package com.JrodManU.LaserJumper;
import com.JrodManU.LaserJumper.screens.*;
import com.badlogic.gdx.Game;
public class LaserJumper extends Game{
InGameScreen inGameScreen;
public Preferences preferences;
public GameEventListener gameEventListener;
@Override
public void create() {
inGameScreen = new InGameScreen(this);
setScreen(inGameScreen);
}
public void changeToInGame() {
inGameScreen = new InGameScreen(this);
setScreen(inGameScreen);
}
public LaserJumper(GameEventListener listener) {
gameEventListener = listener;
}
public void showAd() {
gameEventListener.showAd();
}
public void loadAd() {
gameEventListener.loadAd();
}
public boolean isShowing() {
return gameEventListener.isShowing();
}
public boolean isLoaded() {
return gameEventListener.isLoaded();
}
}
And finally, the interface GameEventListener
package com.JrodManU.LaserJumper;
public interface GameEventListener {
public void showAd();
public void loadAd();
public boolean isShowing();
public boolean isLoaded();
}
Your interstitial ad is inside a separate Activity Ad and then you instantiate it directly like this Ad ad = new Ad();
You should never instantiate Android Activities like that (they way to launch Activities is by using Intents), because Activities have to obey the Activity lifecycle and Android will call through the Activities lifecycle methods.
The consequence is that the Ad Activity's onCreate() method isn't called and your InterstitialAd has never been instantiated which leads to a NPE later.
