Solved: INSTALL_FAILED_UPDATE_INCOMPATIBLE

When we tried to install Android APK we had compiled using adb as below, we got an error as, “adb: failed to install APK_PATH Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package com.yourbusiness.app signatures do not match previously installed version; ignoring!]”

$ adb install -r YourBusinessApp.apk
Performing Streamed Install

adb: failed to install YourApp.apk: Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package com.yourbusiness.app signatures do not match previously installed version; ignoring!]

Solution :

This error is because there is already an installed App with same package name in your mobile and the installed App is either downloaded from play-store or release version of it is generated using different sign keys.

Hence, just uninstall the current app from your Android device from Settings or from adb console as,

$ adb uninstall com.yourbusiness.app

Where “com.yourbusiness.app” is package name we used, you should replace it with your app’s package name.

Now if you install the new APK, it should get install without any issues.
