错误描述

这个错误是在编译 Android APP 时，无法找到对应的 debug.keystore 文件导致的验签失败，只需要重新生成 debug.keystore 文件即可。

解决方案

进入 RN 项目的 android/app 目录中执行下面命令来重新生成 debug.keystore 文件。

keytool -genkey -v -keystore debug.keystore -storepass android -alias androiddebugkey -keypass android -keyalg RSA -keysize 2048 -validity 10000
