Why is there a delay between closing interstitial ad and opening the target activity? - android-activity

Question

I implemented this android code to load and show an interstitial ad and after closing the ad it will open the target activity, but my problem is there's a 3 seconds delay between closing and opening the target activity...here's my code:
AdRequest adRequest = new AdRequest.Builder().build();
InterstitialAd.load(HomeActivity.this, UNIT_ID, adRequest, new InterstitialAdLoadCallback() {
#Override
public void onAdLoaded(#NonNull InterstitialAd interstitialAd) {
// The mInterstitialAd reference will be null until
// an ad is loaded.
admobInterstitialAd = interstitialAd;
admobInterstitialAd.setFullScreenContentCallback(new FullScreenContentCallback() {
#Override
public void onAdDismissedFullScreenContent() {
super.onAdDismissedFullScreenContent();
admobInterstitialAd = null;
/**********Here is the delay when starting the activity for about 3 seconds*******/
Intent intent = new Intent(HomeActivity.this, SettingsActivity.class);
startActivity(intent);
/********************************************************************************/
}
#Override
public void onAdFailedToShowFullScreenContent(com.google.android.gms.ads.AdError adError) {
super.onAdFailedToShowFullScreenContent(adError);
admobInterstitialAd = null;
Intent intent = new Intent(HomeActivity.this, SettingsActivity.class);
startActivity(intent);
}
#Override
public void onAdShowedFullScreenContent() {
super.onAdShowedFullScreenContent();
admobInterstitialAd = null;
}
});
if (admobInterstitialAd != null) {
admobInterstitialAd.show(HomeActivity.this);
}
}
#Override
public void onAdFailedToLoad(#NonNull LoadAdError loadAdError) {
// Handle the error
admobInterstitialAd = null;
Intent intent = new Intent(HomeActivity.this, SettingsActivity.class);
startActivity(intent);
}
});
Any suggestions to fix this issue....thanks in advance...

I faced the same problem. I still haven't been able to fix the problem and couldn't find a resource that does. While searching on Google, I realized that you are not alone and those who have the same problem on other platforms.
As a workaround, I will use a progress dialog. This makes users wait until the ad closes and the new event starts. I think 1-3 seconds.
if (mInterstitialAd != null) {
mInterstitialAd.show(MainAct.this);
startActivity(new Intent(MainAct.this, NewAct.class));
progressDialog.show();
} else {
startActivity(new Intent(MainAct.this, MafA.class));
}
