这是我的项目：https://github.com/kenpeter/my_hak_news https://github.com/kenpeter/my_hak_news，它是直接复制https://github.com/grigio/HAgnostic-News https://github.com/grigio/HAgnostic-News.
git克隆https://github.com/kenpeter/my_hak_news https://github.com/kenpeter/my_hak_news，然后运行react-native run-android
得到这个错误：
* What went wrong:
Execution failed for task ':app:installDebug'.
> com.android.builder.testing.api.DeviceException: com.android.ddmlib.InstallException: Failed to finalize session : INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package com.hagnosticnews signatures do not match the previously installed version; ignoring!
相关问题：https://github.com/grigio/HAgnostic-News/issues/1 https://github.com/grigio/HAgnostic-News/issues/1，我尝试了各种方法，但无法解决这个问题。
我的项目中也遇到了这个问题。
这对我有帮助，所以希望能帮助其他人：
adb uninstall "com.domain.yourapp"
