android - React Native + Android:transformClassesWithDexForDebug失败

Question

我在https://facebook.github.io/react-native/docs/getting-started.html上非常仔细地遵循了说明，为我的React Native项目设置了Android AVD环境。在现有项目上运行react-native run-android时收到此错误:

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

我能够很好地运行一个新的react-native init AwesomeProject，因此我在我现有的项目及其依赖关系中假设了它。我知道Firebase的Firestack可能是罪魁祸首，因为它对build.gradle文件进行了一些更改。我搜索了StackOverflow和Google，并尝试了许多建议。没有工作。通过阅读，我发现build.gradle文件中可能存在某些原因，因此我也将它们发布了。

根build.grade

应用程式build.gradle

Answer 1

发生的情况是，您可能有两个不同的库都在提取com.google.android.gms，因此您可以尝试将其排除在react-native-firestack之外。

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