NoClassDefFoundError:com.google.firebase.FirebaseOptions

Question

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

我尝试了用Google搜索的解决方案,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？

这是错误日志:

Answer 1

这就是我解决问题的方法:

1. 将编译'com.android.support:multidex:1.0.2'添加到app/build.gradle.

2. 将android:name ="android.support.multidex.MultiDexApplication"添加到AndroidManifest.xml中的应用程序标记中.

   如果您使用的是自定义的应用程序类,跳过AndroidManifest.xml中,让你的应用类扩展MultiDexApplication而不是应用.

Answer 2

我有同样的问题，我已经解决了：

您必须替换android:name=".app"为android:name="android.support.multidex.MultiDexApplication"
