I can't run an existing react-native-cli app into my android device. Similar thing happened for iOS emulator, but I'm managed to solve it. So now I can only run into iOS not android. Please take a look at the error message and tell me what to do.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:installDebug'.
> com.android.builder.testing.api.DeviceException: com.android.ddmlib.InstallException: INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package com.banana.apple signatures do not match previously installed version; ignoring!

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

You must have installed the app previously ( possibly from the play store ) with a different version code and version name. So in order to build and run the app, you need to uninstall the previously installed app with package id

com.banana.apple

You can do this in 2 ways:

  1. Manually uninstalling just like any other app from your device
  2. Run the following command when connecting your phone via USB (source).

adb uninstall "com.banana.apple"
