Flutter + Android Studio：无法解析外部库中的Java符号

[英]Flutter+Android Studio: Can't resolve Java symbols from external libraries

原文 2017-10-13 21:22:28 1 1 java/ android/ flutter

I'm trying to build a Flutter app that also runs custom Java code, so that I can execute code in the background, set alarms etc. As such, I'd like to access Firebase from Java. 我正在尝试构建一个同时运行自定义Java代码的Flutter应用程序，以便我可以在后台执行代码，设置警报等。因此，我想从Java访问Firebase。

I've created a new Flutter project in Android Studio and added Firebase as documented here (manually). 我在Android Studio中创建了一个新的Flutter项目，并在此处（手动）添加了Firebase。

It compiles and runs fine on the device, but it seems that the dependency .jars from Gradle are not picked up in Android Studio, and as a result my Java source files show a lot of errors - source being "cannot resolve symbol 'google'" in the import statements. 它在设备上编译并运行良好，但似乎在Android Studio中没有拾取Gradle的依赖.jars，因此我的Java源文件显示了很多错误 - 来源是“无法解析符号'google' “在进口报表中。

Is there anything special that I need to do in order to have Android Studio pick up external Java dependencies from Gradle in Flutter application projects? 为了让Android Studio在Flutter应用程序项目中从Gradle中获取外部Java依赖项，我需要做些什么特别的事情吗？ I'm running Android Studio 3.0 Beta 7. 我正在运行Android Studio 3.0 Beta 7。
