你的申请课呢？如果您没有一个，您需要创建一个，并将它的名称放在清单文件中，您的代码应该如下所示

AndroidManifest.xml

<application
        android:name="ApplicationName"
...
>

您的应用程序类将是：

public class ApplicationName extends MultiDexApplication{
.....

 @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(this);
    }
}
