React Native + Android：transformClassesWithDexForDebug失敗

Question

我在https://facebook.github.io/react-native/docs/getting-started.html上非常小心地按照指示爲我的React Native項目設置了Android AVD環境。

Dex: Error converting bytecode to dex: 
Cause: com.android.dex.DexException: Multiple dex files define Lcom/google/android/gms/internal/zzble;

:app:transformClassesWithDexForDebug FAILED 

FAILURE: Build failed with an exception. 

* What went wrong:

我能夠運行一個新的react-native init AwesomeProject就好了，所以我認爲它的東西與我現有的項目和它的依賴關係：當我在我現有的項目運行react-native run-android我得到這個錯誤。我知道Firestack Firebase可能是罪魁禍首，因爲它對build.gradle文件進行了一些更改。我搜索了StackOverflow和Google，並嘗試了許多消化方法。沒有工作。從我的閱讀中可以看出，我的build.gradle文件中可能有些東西可能是原因，所以我也會發布它們。

根build.grade

應用build.gradle

發生了什麼事是，你可能有兩個不同的庫都拉着com.google.android.gms，所以你可以嘗試只排除它react-native-firestack。

compile (project(':react-native-firestack')) { 
     exclude group: 'com.google.android.gms' 
}
