java - Android AdView NoClassDefFoundError

Question

我是 Android 开发的初学者。我刚刚发布了一个应用程序，但发现了一些问题，因此我想通过创建一个新的 Android 项目来纠正这些问题，该项目的包名称与已发布的应用程序的包名称相同。但是，一旦我完成更新应用程序，该应用程序就不会在手机上运行(调试)。说“不幸的是，这个应用程序已停止。”这次我也尝试合并 adMob。

请帮助我，因为我必须尽快发布此内容。

这是应用程序崩溃后的 Logcat:

这是我的 Admob 展示位置的 XML。我刚刚关注了this link添加admob。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/easyb"
tools:context=".BlueActivity" >

<LinearLayout
    android:id="@+id/adviewPlaceholder"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true"
    android:orientation="vertical" >
</LinearLayout>

//Other elements

我已将其放入我的 list 文件中 >

<activity android:name="com.google.ads.AdActivity" 
        android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" >

    </activity>

这在我的 Activity onCreate 方法中 >

private AdView ad;


@Override
protected void onCreate(Bundle savedInstanceState) {
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_blue);

    initAdView();
//Other elements
protected void initAdView() {

    ad = new AdView(this, AdSize.SMART_BANNER, "a15204b9eb97566");

    LinearLayout ll = (LinearLayout)findViewById(R.id.adviewPlaceholder);

    ll.addView(ad);

    ad.loadAd(new AdRequest());
}

protected void destroyAdView() {
    if(ad != null) ad.destroy();
}

@Override
protected void onDestroy() {    
    // destroy the ad when the activity is destroyed
    destroyAdView();
    super.onDestroy();
}

提前致谢

根据错误消息中的这一行:

08-11 02:28:56.973: E/AndroidRuntime(27461): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.gamerspitch.easybluetooth/com.gamerspitch.easybluetooth.BlueActivity}: android.view.InflateException: Binary XML file line #9: Error inflating class com.google.ads.AdView

您的 AdView 存在问题，导致应用崩溃。

您能否发布您的 .xml 布局文件以及 Activity。

更新:

为了让这一点更清楚。我从未在 .xml 中定义 AdView。我只是在布局 .xml 文件中创建一个没有子项的布局，然后通过代码将 AdView 添加到其中。它看起来像这样:

      private AdView ad;

      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);

          setContentView(R.layout.yourlayout);

          initAdView();

          // other code...
      }

       protected void initAdView() {

            ad = new AdView(this, AdSize.SMART_BANNER, "MY_AD_UNIT_ID");

            LinearLayout ll = (LinearLayout) findViewById(R.id.adviewPlaceholder);

            ll.addView(ad);

            ad.loadAd(new AdRequest());
        }

        protected void destroyAdView() {
            if(ad != null) ad.destroy();
        }

        @Override
        protected void onDestroy() {    
            // destroy the ad when the activity is destroyed
            destroyAdView();
            super.onDestroy();
        }

布局 yourlayout.xml 文件:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent >

    <!-- lots of other layout stuff here -->


    <!-- make the adview be on the bottom of the screen -->
    <LinearLayout
        android:id="@+id/adviewPlaceholder"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:orientation="vertical" >
    </LinearLayout>
 </RelativeLayout>
