NoClassDefFoundError的：com.google.firebase.FirebaseOptions（火力和AdMob）

Question

我在苦惱，因爲：

java.lang.NoClassDefFoundError: com.google.firebase.FirebaseOptions at com.google.firebase.FirebaseApp.initializeApp(Unknown Source) at com.google.firebase.provider.FirebaseInitProvider.onCreate(Unknown Source) at android.content.ContentProvider.attachInfo(ContentProvider.java:1214) at android.content.ContentProvider.attachInfo(ContentProvider.java:1189) at com.google.firebase.provider.FirebaseInitProvider.attachInfo(Unknown Source) at android.app.ActivityThread.installProvider(ActivityThread.java:4912) at android.app.ActivityThread.installContentProviders(ActivityThread.java:4518) at android.app.ActivityThread.handleBindApplication(ActivityThread.java:4458) at android.app.ActivityThread.access$1300(ActivityThread.java:144) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1319) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:137) at android.app.ActivityThread.main(ActivityThread.java:5136) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:525) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:737) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:553) at dalvik.system.NativeStart.main(Native Method)

這當您使用在項目中發揮谷歌服務的依賴通常會發生。

只需將google play-service依賴項降級到compile 'com.google.android.gms:play-services:8.3.0'，問題就可能得到解決。
