Unable to run apk on nexus 5 after upgrading to 5.1.1
Using Cordova: 5.0.0 Device : Nexus 5 Machine : MAC
BUILD
I think you have this issue because the app is installed on your device with a different signature.
When you do cordova run android, the app is installed with a debug signature and maybe that signature changed when you changed target sdk or when you upgraded android.
The fix when you have INSTALL_FAILED_UPDATE_INCOMPATIBLE error is to first uninstall your app and then you should not have the issue any-more when launching cordova run android
Don't worry about that.for NEXUS 5.go to Settings>> apps>> search application.
Well done..
