Error inflating class com.google.ads.AdView

Question

Hello I am new to android dev and admob. I am trying to make a simple test app with a button, a couple pages and admob at the bottom. Everything works fine until I try implementing admob. Here is my code:

HelloAndroid.java:

package com.manny.HelloAndroid;  import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.widget.ImageView;  public class HelloAndroid extends Activity {     /** Called when the activity is first created. */     private static final int ACTIVITY_CREATE = 0;     @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);           setContentView(R.layout.main);         ImageView image = (ImageView) findViewById(R.id.test_image);         //image.setScaleType(ImageView.ScaleType.FIT_XY);      }     public void onClick(View v){         Intent i = new Intent(this, HelloPage2.class);         startActivityForResult(i, ACTIVITY_CREATE);     } } 

main.xml:

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:orientation="vertical" >      <ImageView          android:id="@+id/test_image"         android:src="@drawable/bak_vert_480x800"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_centerHorizontal="true"         android:scaleType="fitXY"         />      <TextView         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:text="@string/hello" />     <ImageButton          android:id="@+id/test_button"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:src="@drawable/btn_arrow"         android:layout_marginLeft="100dp"         android:layout_marginTop="200dp"         android:onClick="onClick"         />      <com.google.ads.AdView android:id="@+id/adView"                          android:layout_width="wrap_content"                          android:layout_height="wrap_content"                          ads:adUnitId="b14be806e9ddf1f"                          ads:adSize="BANNER"                          ads:testDevices="TEST_EMULATOR, TEST_DEVICE_ID"                          ads:loadAdOnCreate="true"/>  </RelativeLayout> 

hello android Manifest:

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"     package="com.manny.HelloAndroid"     android:versionCode="1"     android:versionName="1.0" >      <uses-sdk android:minSdkVersion="7"          android:targetSdkVersion="13"/>      <application         android:icon="@drawable/ic_launcher"         android:label="@string/app_name"          android:theme="@android:style/Theme.NoTitleBar.Fullscreen">         <activity             android:name=".HelloAndroid"             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=".HelloPage2">         </activity>     <activity android:name="com.google.ads.AdActivity"                     android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|s    mallestScreenSize"/>   </application>   <uses-permission android:name="android.permission.INTERNET"/>   <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> </manifest>

I am using GoogleAdMobAdsSdkAndroid-6.0.0. Again I am very new to this and I have tried using examples off multiple sites but the app continues to crash when it hits a page with admob in it. If someone can help me it would be much appreciated. Thank you. If more code is needed let me know.

Answer 1

Have you recently updated your Android Tools to r17 or higher? If so, you need to create a libs/ folder in your project, and physically put the SDK in the project. Or, in the Java Build Path, you must Order and Export the SDK jar.

Otherwise, the jar doesn't get included when your apk gets compiled, and all hell breaks loose when you run AdMob code at runtime.

NOTE: This applies to any library your project references.
