android - NoClassDefFoundError : com. 谷歌.firebase.FirebaseOptions

Question

我在使用的其他测试设备 (4.4.2) 上不断收到 NoClassDefFoundError。但在我的测试设备 (Android 5.1) 上运行良好。

我尝试了我在谷歌上搜索过的解决方案，但似乎没有任何效果。

我正在使用 Firebase 实时数据库。有人可以帮忙吗？

错误日志如下:

Answer 1

这就是为我解决问题的方法:

1. 添加编译'com.android.support:multidex:1.0.2'到应用程序/build.gradle.

2. 将android:name="android.support.multidex.MultiDexApplication"添加到AndroidManifest.xml中的应用标签。

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