我是 Android 开发的初学者。我刚刚发布了一个应用程序,但发现了一些故障,所以我想通过创建一个与已发布应用程序包名称相同的新 Android 项目来纠正这些故障。但是一旦我完成了更新应用程序,这个应用程序就没有在手机上运行(调试)。说“不幸的是,这个应用程序已停止。” 这次我也尝试加入 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。我只是按照此链接添加 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

我已经把它放在我的清单文件中>

<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: 无法启动活动 ComponentInfo{com.gamerspitch.easybluetooth/com.gamerspitch.easybluetooth.BlueActivity}: android.view.InflateException: Binary XML 文件第 9 行:膨胀类 com.google.ads.AdView 时出错

您的 AdView 存在问题,导致应用崩溃。

您能否发布您的 .xml 布局文件以及活动。

更新:

为了使这一点更清楚一点。我从不在 .xml 中定义 AdView。我只是在我的布局 .xml 文件中创建一个没有子级的布局,然后通过代码将 AdView 添加到它。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();
        }

和布局 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>

看起来您的 adView 导致了崩溃。你是如何实施的?您是否在清单中包含了所有所需的权限?

ClassNotFound 异常表明您的 admob 库没有连接到您的 XML。有几件事会导致这种情况,但最有可能的是它没有在清单中声明:

 <application android:icon="@drawable/icon" android:label="@string/app_name"
           android:debuggable="true">
  <activity android:label="@string/app_name" android:name="yourActivity">
       .....
  </activity>
  <activity android:name="com.google.ads.AdActivity"   <----- this line
            android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>
 </application>

或者它没有在 XML 文件的顶部声明:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"   <----- this line
          android:orientation="vertical"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent">
   <com.google.ads.AdView android:id="@+id/adView"
                     android:layout_width="wrap_content"
                     android:layout_height="wrap_content"
                     ads:adUnitId="MY_AD_UNIT_ID"
                     ads:adSize="BANNER"
                     ads:testDevices="TEST_EMULATOR, TEST_DEVICE_ID"
                     ads:loadAdOnCreate="true"/>
    </LinearLayout>

试试这些,如果他们不成功,请查看谷歌的文档herehere

您的代码或 XML AFAICT 没有任何问题。该错误明确指出:

Could not find class 'com.google.ads.AdView'

您部署的应用似乎不包含 Admob 库。你需要弄清楚为什么。检查您的构建工具/环境。
