This can happen if you sign your application with a different certificate  You can always use  adb install -r myapk apk   to overwrite an existing apk on your device  but you will still get the error if you signed the new apk with a different certificate that of the installed apk   In that scenario you would need to uninstall the apk from your device before attempting an install  However  this can also impact your application since your original signing may be tied to certain Developor API s  so you may need to update the console with your new credentials

Uninstalling the application would be enough to avoid this problem  INSTALL FAILED UPDATE INCOMPATIBLE  but sometimes even uninstalling the message is raised again  it occurs in Android OS 5 0    so this is the solution  Go to Settings  gt  Apps and you will find your app with the message    quot Not installed for this user quot    We have to uninstall manually for all users   then we can install our compiled application with no problems   Another options   Remove the old application and install again   Use Android Debug Bridge command   adb uninstall  PACKAGE NAME

I don t see anyone mentioning my case so let me add it - it happens when you build the app in one mode  e g  Dev  and then try to override it with a different mode  e g  Production     The solution is the same as for the other cases - delete the app on the device simulator and run again

If you are attempting to debug from a different computer than you were originally you will get the dreaded INSTALL FAILED UPDATE INCOMPATIBLE error   However  there is a way to proceed without uninstalling the app and losing your data   To see how to transfer the debug keystore that is required so you don t get the message  The device already has an application with the same application but a different signature  In order to proceed you will have to uninstall the existing application    and lose your data   See Update the app in another machine with same debug keystore in android
