尝试运行 flutter 运行的 android 应用程序时出错

Question

突然，我在尝试运行使用 flutter 和 dart 创建的应用程序时开始收到此错误。 我是 android 开发的新手。 任何帮助表示赞赏。

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:packageDebug'.

Answer 1

这导致您的错误signing-config.json (Access is denied)

删除此文件，它应该可以工作，位于D:\DEVELOPEMENT\Android\flutter_projects\nav_app\build\app\intermediates\signing_config\debug\out\signing-config.json 。

Answer 2

删除这个位置的文件D:\DEVELOPEMENT\Android\flutter_projects\nav_app\build\app\intermediates\signing_config\debug\out\signing-config.json

并做一个flutter clean 。
