Cloud Firestore:DexArchiveMergerException无法合并dex

Question

当我包括:

编译'com.firebaseui:firebase-ui-firestore:3.1.0'

构建失败.firestore版本3.0.0是相同的结果.

没有这个代码,构建就是成功的.

有重复的模块吗？请帮我.

错误:任务':app:transformDexArchiveWithExternalLibsDexMergerForDebug'的执行失败.

Answer 1

你的代码没有错.几天前我遇到了同样的问题,我很简单地解决了这个问题:

1. Clean
2. Rebuild

不要忘记在build.gradle文件中包含以下代码行(Module:app).

android {
    defaultConfig {
       multiDexEnabled true
    }
}

如果它仍然不能如上所述,只是delete the .gradle directory然后run your app again.
