此版本中使用了不推荐的Gradle功能，使其与Gradle 6不兼容

Question

我试图让Apk反应原生，但是它没有给我任何东西。它说，Apk文件中的发布文件是空的，在Gradlew捆绑发布完成后

Answer 1

在2020年，如果你有同样的问题，Powershell的这个建议对我很有帮助。

.\emulator.exe-avd"MyAvd"

在SDK emulator所在的目录（C:\Users\AppData\Local\Android\SDK\emulator）中运行上述命令，然后您可能会得到一些说明，如下所示：

您的模拟器已过时，请通过启动Android Studio更新：

• 启动Android Studio
• 选择“工具”菜单

这发生在我的一个项目中。这是在Windows中逐步修复它的步骤（10 64位）：

1） 在没有Android Studio的情况下运行avd(https://windowsloop.com/launch-avd-manager-without-android-studio/)

2）在另一个控制台运行在您的项目gradle包装器（您必须安装Gradle 5.4.1（https://gradle.org/install/））

3） 然后移动到cd android，在这里运行gradlew clean

4） 移动到根目录cd 并运行react native start

5）在另一个控制台运行在您的项目反应本地运行Android
