public void onAdLoaded(){
interstitial.show();
}
});
} // end onCreate
public void displayInterstitial (){
if (mInterstitialAd.isLoaded()) {
mInterstitialAd.show();
}
}
// in AndroidManifest.xml
<Activity
android:screenOrientation="portrait" // or landscape
// in MyActivity.java
boolean mbOrientacionLandscape = false;
int nOrientation = getResources().getConfiguration().orientation;
if(mbOrientacionLandscape==true){
getResources().getConfiguration();
if(nOrientation != Configuration.ORIENTATION_LANDSCAPE)
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
