我尝试在Android设备上运行我的React Native应用程序。该应用已成功安装在手机上，但无法启动。
我发现其他人也有同样的问题。对于他们而言，将其修复为.gradle-files中的编译版本很有帮助。但是对我来说，它们似乎还不错。

* cycle. By default, bundleDebugJsAndAssets is skipped, as in debug/dev mode we prefer to load the
* bundle directly from the development server. Below you can see all the possible configurations
* and their defaults. If you decide to add a configuration block, make sure to add it before the
* `apply from: "../../node_modules/react-native/react.gradle"` line.
