接受的答案不能解决我的问题。

如果您使用Multidex，则您的应用程序应该扩展MultiDexApplication而不是Application。

MyApplication.java

public class MyApplication extends MultiDexApplication{

     ...

}

AndroidManifest.xml

<application

      android:name="your.package.name.MyApplication"

      android:allowBackup="true"

      android:icon="@mipmap/ic_launcher"

      ...

      />

希望能帮助到你。
