android – NoClassDefFoundError：com.google.firebase.FirebaseOptions

我继续得到我正在使用的其他测试设备(4.4.2)上的NoClassDefFoundError.但在我的测试设备( Android 5.1)上工作正常.

我尝试了我已经搜索的解决方案,没有什么似乎有效.

我正在使用Firebase实时数据库.有人可以帮忙吗？

这是错误日志：

解决方法

这是什么解决了我的问题：

>将编译’com.android.support:multidex:1.0.1’添加到
应用程序/的build.gradle.
>将android：name =“android.support.multidex.MultiDexApplication”添加到AndroidManifest.xml中的应用程序标签.

如果您使用自定义应用程序类,请跳过AndroidManifest.xml,并使您的Application类扩展MultiDexApplication而不是应用程序.
