Android: Admob InterstitialAd Crash At LoadAd

I'm using InterstitialAd by Admob. My app crashes at 'loadAd' only in the first time it's called, and it's not reproducible (it happens once in 100-200 runs less or more). the ad u

Solution 1:

Sometimes what happen is Ad does to get loaded into your buffer so when you try to call loadAd, it crashes onCreate:

    mInterstitialAd = new InterstitialAd(this);
    // set the ad unit ID
    mInterstitialAd.setAdUnitId(getString(R.string.ad_id));

    AdRequest adRequest2 = new AdRequest.Builder()
            .build();
    // Load ads into Interstitial Ads

    mInterstitialAd.loadAd(adRequest2);

    mInterstitialAd.setAdListener(new AdListener() {
        public void onAdLoaded() {
            showInterstitial();
        }
    }); 

In the same class:

private void showInterstitial() {
    if (mInterstitialAd.isLoaded()) {
        mInterstitialAd.show();
    }
}

Solution 2:

Activtiy_m1.java

public class Activity_m1 extends AppCompatActivity {

    InterstitialAd interstitial;
    Activity mactivity;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_m1);
        setTitle("ABCD");
        Advertise.displaym1(getApplicationContext());
    }

    @Override
    public void onBackPressed() {
            Advertise adv = new Advertise();
            adv.disp_adm1();
        finish();
    }
}

Advertise.java

public class Advertise {
    public static InterstitialAd interstitial;

    public static void displaym1(Context act) {
        interstitial = new InterstitialAd(act);
        interstitial.setAdUnitId("ca-app-pub-2621588945556564/3343556333");
        AdRequest adRequest1 = new AdRequest.Builder().build();
        interstitial.loadAd(adRequest1);
    }
    public void disp_adm1() {
        if (interstitial.isLoaded())
            interstitial.show();
    }
}
