Firebase react-native 无法访问

Question

我将 firebase 添加到我的 react 本机应用程序中。我正在尝试在android中编译它，但我们遇到了问题。我团队的其他成员没有任何问题，他们中的一些人无法运行它并且他们正在收到消息。

 basePerformance.java:39: error: cannot access zze
    getOrCreateTrace(identifier).start();
                            ^
 class file for com.google.android.gms.internal.firebase-perf.zze not found

这听起来像是一个依赖问题或类似的问题。我们现在正在挣扎一天，对此我们一无所知。有人可以帮忙吗？这是我们的毕业典礼

Answer 1

最后我解决了这个问题。这是用于编译的 Java SDK 的问题。如果您使用 SDK 9 或 10，您将面临此错误。我将其更改为 Java 8，现在可以使用了。

Answer 2

固定更改为 Java 8

检查你正在使用的版本java -version

export JAVA_HOME=`/usr/libexec/java_home -v 1.8`
