AdMob app keeps crashing

Question

My Code: Java:

import android.os.Bundle;
import android.app.Activity;
import android.util.AttributeSet;
import android.view.Gravity;
import android.view.Menu;
import android.widget.LinearLayout;

import com.google.ads.AdRequest;
import com.google.ads.AdSize;
import com.google.ads.AdView;

public class MainActivity extends Activity
{

private AdView adView;

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    adView = (AdView) findViewById(R.id.adView);

    AdRequest request = new AdRequest();
    request.setTesting(true);
    adView.loadAd(request);

}

@Override
protected void onDestroy()
{
    super.onDestroy();
    if(adView!=null) adView.destroy();
}

@Override
public boolean onCreateOptionsMenu(Menu menu)
{
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

}

xml:

<LinearLayout xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/linearlayout"
    android:orientation="vertical">

<com.google.ads.AdView
        android:id="@+id/adView"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        ads:adUnitId="MY_UNIT_ID"
        ads:adSize="BANNER"
        ads:testDevices = "MY_TEST_DEVICE"
        android:layout_gravity="bottom"/>
</LinearLayout>

Manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="...."
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="10"
    android:targetSdkVersion="16" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com....MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name="com.google.ads.AdActivity"
              android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>
</application>

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

It just keeps crashing on my testing device in this line: setContentView(R.layout.activity_main); The App isnt published in the Play Store, because i want to test it first. So the error should be in the xml. I hope you can help me.

EDIT: logcat:

Answer 2

You need to import the googleadmob.jar in your project... download it from admob site and and extract the googleAdmobAdsSdk.jar from it.. copy it into your libs folder of project

now Right Click on project ->Build Path->java Build Path->libraries check if the jar is imported and if not than click on add jar and add it from libs folder

NOW check the Order and Export tab and make sure that there is tick on that jar

click ok

may be this could help..

Answer 3

You need to declare xmlns:android at the start of LinearLayout

You also need to import the admob code to the library
