执行命令后发生运行时异常 在this教程和this示例演示

之后buck install --run demo_app_android

然后,控制台

中显示以下内容
Installing apk on emulator-5554 (null).
[-] PROCESSING BUCK FILES...FINISHED 0.0s [100%]   File removed

最后,设备会显示一条消息Buck Demo App has stopped 该应用已成功安装,因为我可以在应用列表中看到它,但它无法正常工作

设备规格:

  • 原生Android模拟器(也将其运行到具有相同结果的真实设备中)
  • Nexus 5 API 24

我的电脑:

  • MacBook pro 2012年中期

注意:此外,此问题已直接报告给buck repository,但尚未提供解决方案

关于如何解决它的任何想法?

1 个答案:

答案 0 :(得分:1)

重复github的回答:

您需要从here(版本10e)安装Android NDK并将ANDROID_NDK_REPOSITORY设置为解压缩NDK的位置(有关详情,请参阅buckconfig部分)。

例如,如果您将NDK解压缩到~/tmp/ndk(以便有一个目录~/tmp/ndk/android-ndk-r10e),则需要将ANDROID_NDK_REPOSITORY设置为~/tmp/ndk

之后删除旧缓存并重建应用程序:

$ buck kill && rm -rf buck-out
$ buck build demo_app_android
