INSTALL_FAILED_UPDATE_INCOMPATIBLE when I try to i

Question

I've compiled Trebuchet launcher from CyanogenMod 9, and trying to install it with adb:

$ adb install out/target/product/generic/system/app/Trebuchet.apk
3986 KB/s (7870141 bytes in 1.928s)
    pkg: /data/local/tmp/Trebuchet.apk
Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE]

I tried on Nexus S with CM9 and Galaxy Nexus with stock JB. Why I'm getting this error?

EDIT: In my case I've tried to reinstall system package with package manager. That's not supported, so I've got this error. Source of the error may differ in your case.

Answer 1

It happened to me when I installed a dev build using Instant Run, and uninstalled from Google Play. For some reason the data from Instant Run is still in the device and can't install/uninstall the app again.

Only way to fix it: - disable Instant Run in android studio - install from android studio (it should work only from here) - uninstall app

now it should be clean to install from Google Play or adb.

Answer 2

Try

adb uninstall package-name

It works for me. I have remove my app using Titanium Backup. However,I think Titanium backup didn't removed my app totally.

Answer 4

if the APK is built in project with Android.mk file. Maybe it's because of the sign certificate has been changed.

in my problem, I have add LOCAL_CERTIFICATE := platform. as the original apk is signed without this tag.
