Admob - Problems with Ads in APP

Question

I did everything as ADMOB site tutorial says, I put the layout in XML, imported the path from Google Play Sevices and added the tutorial code lines, my application compiles, but no longer opens on smartphone, an alerat message appears saying that the app has stopped and in the Eclipse log appears the following message (below), I need a help.

Message in the Eclipse:

    adView.loadAd(new AdRequest());

Answer 1

I looked at the Droidgap code in the Cordova. And from what I understand, it is not possible to do the way you did, including an android layout of yours with Adsview, because it always overwrites the layout.

You’ll have to go that way:

import android.os.Bundle; 
import org.apache.cordova.*;
import com.google.ads.*;
import android.widget.LinearLayout;

public class MainActivity extends DroidGap {
    private static final String AdMob_Ad_Unit = "xxxxxxxxxxxxxxx";
    private AdView adView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // Set by <content src="index.html" /> in config.xml
        super.loadUrl(Config.getStartUrl());
        //super.loadUrl("file:///android_asset/www/index.html")

        adView = new AdView(this, AdSize.BANNER, AdMob_Ad_Unit); 
        LinearLayout layout = super.root; 
        layout.addView(adView); 
        AdRequest request = new AdRequest();

        // Comment this out before publishing.
        // request.addTestDevice(AdRequest.TEST_EMULATOR);
        adView.loadAd(request); 
    }
}

Another suggestion is, although the tutorial uses the DroidGap, use the CordovaActivity for the DroidGap this marked as @Deprecated.

There is a tutorial on codetheory, that will help you include Ads in your app.
