在API 22及更低版本上启动我的ap时出现以下异常(在API 24,目标和编译API上运行良好)。

如果我评论使用AdWordsConversionReporter的行(它可以是库类或自定义类),它会移动到另一个类。

似乎与Multidexing有关,但我很确定我使用它很好。 在我的gradle中,我有以下几行:

multiDexEnabled true

compile('com.android.support:multidex:1.0.1') {
    exclude group: 'com.android.support'
}

以下是我的应用程序类的一部分:

public class MyApplication extends MultiDexApplication {
..
}

我的清单的一部分:

    <application
        android:name=".ui.MyApplication"
        android:allowBackup="true"
        android:hardwareAccelerated="true"
        android:icon="@mipmap/icon"
        android:label="@string/app_name"
        android:theme="@style/AppTheme"
        tools:replace="android:theme">

我在很多问题上尝试了很多解决方案看起来类似于在我的Application类上添加MultiDex.install(this),清理我的项目,重新同步Gradle,在我的gradle上启用minify(以及更多)但没有任何作用。 解决它的任何解决方案?

通过添加
