How can I set interstitial ads on URL clicks in WebView App? - url

Question

I have implemented following code for interstitial ads .Problem I am facing is that interstitial ad is shown only on first URL click. I want to adjust ads on every URL click or every 5th URL click in WebView app .Help in this regard will highly be appreciated. Following is the code i want to be modified .
private WebView webview;
private AdView mAdView;
private InterstitialAd mInterstitialAd;
SwipeRefreshLayout mySwipeRefreshLayout;
#SuppressLint("SetJavaScriptEnabled")
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MobileAds.initialize(this, new OnInitializationCompleteListener() {
#Override
public void onInitializationComplete(InitializationStatus initializationStatus) {}
});
AdRequest adRequest = new AdRequest.Builder().build();
InterstitialAd.load(this,"ca-app-pub-3940256099942544/1033173712", adRequest,
new InterstitialAdLoadCallback() {
#Override
public void onAdLoaded(#NonNull InterstitialAd interstitialAd) {
// The mInterstitialAd reference will be null until
// an ad is loaded.
mInterstitialAd = interstitialAd;
Log.i("TAG", "onAdLoaded");
}
#Override
public void onAdFailedToLoad(#NonNull LoadAdError loadAdError) {
// Handle the error
Log.i("TAG", loadAdError.getMessage());
mInterstitialAd = null;
}
});
private class WebViewClientDemo extends WebViewClient {
#Override
//Keep webview in app when clicking links
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (mInterstitialAd != null) {
mInterstitialAd.show(MainActivity.this);
} else {
Log.d("TAG", "The interstitial ad wasn't ready yet.");
}
return super.shouldOverrideUrlLoading(view, url);
}

You need to load Ad after each show. Create a static counter variable to load it on everyth nth click.
static int instanceCounter = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LoadInterstitial();
}
private void LoadInterstitial(){
AdRequest adRequest = new AdRequest.Builder().build();
InterstitialAd.load(this,"ca-app-pub-3940256099942544/1033173712", adRequest,
new InterstitialAdLoadCallback() {
#Override
public void onAdLoaded(#NonNull InterstitialAd interstitialAd) {
// The mInterstitialAd reference will be null until
// an ad is loaded.
mInterstitialAd = interstitialAd;
Log.i("TAG", "onAdLoaded");
}
#Override
public void onAdFailedToLoad(#NonNull LoadAdError loadAdError) {
// Handle the error
Log.i("TAG", loadAdError.getMessage());
mInterstitialAd = null;
}
});
}
private class WebViewClientDemo extends WebViewClient {
#Override
//Keep webview in app when clicking links
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (mInterstitialAd != null && isDisplayAdvert()) {
mInterstitialAd.show(MainActivity.this);
LoadInterstitial();
} else {
Log.d("TAG", "The interstitial ad wasn't ready yet.");
}
return super.shouldOverrideUrlLoading(view, url);
}
private bool isDisplayAdvert(){
instanceCounter++;
if(instanceCounter==5){
instanceCounter = 0;
return true;
}
return false;
}

Thanks sir Amod Gokhale . I tried the following code and it is working too .
Would you recommend me about the better one between both codes .
private class WebViewClientDemo extends WebViewClient {
int n = 1;
#Override
//Keep webview in app when clicking links
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (mInterstitialAd != null) {
if( n%6 == 0 )
{
mInterstitialAd.show(MainActivity.this);
} n++;
}
LoadInterstitial();
return super.shouldOverrideUrlLoading(view, url);
}
