Hi all I am using admob in android webview. When i integrated admob and run, it displays following error. My code is as follows:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<com.google.ads.AdView
android:id="@+id/adViews"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentTop="false"
android:layout_centerHorizontal="true"
ads:adSize="BANNER"
ads:adUnitId="ca-123456" >
</com.google.ads.AdView>
<LinearLayout
android:layout_alignParentTop="true"
android:layout_above="@id/adView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ProgressBar
android:id="@+id/progressBar1"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<WebView
android:id="@+id/webView1"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
</LinearLayout>
in code i used as:
private InterstitialAd interstitial;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
overridePendingTransition(R.anim.trans_left_in, R.anim.trans_left_out);
setContentView(R.layout.activity_news);
interstitial = new InterstitialAd(News.this);
// Insert the Ad Unit ID
interstitial.setAdUnitId("ca-app123456");
//Locate the Banner Ad in activity_main.xml
AdView adView = (AdView) this.findViewById(R.id.adViews);
// Request for Ads
AdRequest adRequest = new AdRequest.Builder()
// Add a test device to show Test Ads..comment for real app when launching
.addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
.addTestDevice("CC5F2C72DF2B356BBF0DA198")
.build();
// Load ads into Banner Ads
adView.loadAd(adRequest);
// Load ads into Interstitial Ads
interstitial.loadAd(adRequest);
// Prepare an Interstitial Ad Listener
interstitial.setAdListener(new AdListener() {
public void onAdLoaded() {
// Call displayInterstitial() function
displayInterstitial();
}
});
}
public void displayInterstitial() {
// If Ads are loaded, show Interstitial else show nothing.
if (interstitial.isLoaded()) {
interstitial.show();
}
web=(WebView)findViewById(R.id.webView1);
web.setWebViewClient(new WebViewClient());
pb=(ProgressBar)findViewById(R.id.progressBar1);
ActionBar ab=getActionBar();
ColorDrawable cd=new ColorDrawable(Color.parseColor("#000000"));
ab.setBackgroundDrawable(cd);
ab.setDisplayHomeAsUpEnabled(true);
WebSettings ws=web.getSettings();
ws.setBuiltInZoomControls(true);
web.setWebViewClient(new WebViewClient());
web.setWebChromeClient(new WebChromeClient() {
//showing webview
}
}
When i run the code it displays following error:

I suppose you're using admob via the google play service library and not the old/deprecated admob sdk jar, so in your layout, change :
<com.google.ads.AdView
android:id="@+id/adViews"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentTop="false"
android:layout_centerHorizontal="true"
ads:adSize="BANNER"
ads:adUnitId="ca-123456" >
</com.google.ads.AdView>
to:
<com.google.android.gms.ads.AdView
android:id="@+id/adViews"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentTop="false"
android:layout_centerHorizontal="true"
ads:adSize="BANNER"
ads:adUnitId="ca-123456"/>
回答2:
So the Stacktrace says "Didn't find class com.google.ads.AdView"
That's because you're probably using the Admob SDK via the Google Play Services which is mandatory as of 1st of August. (Otherwise you won't be able to upload an application to the Play Store). So instead of using com.google.ads.AdView you need to use com.google.android.gms.ads.AdView.
You can read more about the Migration of the Admob SDK to the Google Play Services on the official developer site (click)
Edit: By the way, you have to move the Admob-Banner layout-code below the LinearLayout otherwise it won't be visible.
