我在 Android 开发者帐户中获得了下面的堆栈跟踪。此错误仅发生一次。

在我的清单文件中，我声明了com.mysite.myapp.TestApplication. 我的清单文件如下所示：

<application
    android:name="com.mysite.myapp.TestApplication"
    android:icon="@drawable/app_icon"
    android:label="@string/app_name"
    android:theme="@style/Theme.myapp" >
    <activity
        android:name="com.mysite.myapp.ActivityDashboard"
        android:configChanges="orientation|keyboard"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

如果您的主页是 ActivityDashboard.java 插入如下，或者如果 TestApplication.java 将 .ActivityDashboard 替换为 .TestApplication 在活动标签中

<package name="com.mysite.myapp"
    <application
        android:name="TestApplication"
        android:icon="@drawable/app_icon"
        android:label="@string/app_name"
        android:theme="@style/Theme.myapp" >

        <activity android:name=".ActivityDashboard" android:configChanges="orientation|keyboard"
                android:label="@string/app_name" >
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />

                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
            </activity>
    ......
    </application>

android:name="com.mysite.myapp.ActivityDashboard"

将清单中的上述内容替换thr为以下内容。

 android:name=".ActivityDashboard"

或者：

android:name="com.mysite.myapp.TestApplication.ActivityDashboard"
