I published a version of my app to market.
My project somehow corrupted.
I started a new project with the same package-name and same key-store
But when i run the project gives me this error: INSTALL_FAILED_UPDATE_INCOMPATIBLE

I think the new APK is generated with different Signature than the published one.

How can i generate APK with the same Signature with the published one?!
Thanks.

Do you already have that app installed on the device on you are trying to run..

This may help:

  1. Uninstall App adb uninstall package-name

  2. Reboot Device (if problem still exists)

    there may be signature difference between the app that is installed on your device and the app you are trying to install.

  • Why android studio generates different signature? i use the same key-store. and I think its weird. – RaminBoodaghi Apr 07 '16 at 14:27
  • having same signatures we often get this error. may be your signature are not different, you should try to uninstall the app once. – Rakesh Apr 07 '16 at 14:35

I had the same problem after installing the app-release.apk on the emulator with drag and drop.

Uninstall the drag and drop app-release.apk version did solve the problem.

For me, I had the an android phone connected and also had the emulator running, so the failure was not on the actual device but on the emulator. Should have ready the error message better. Had to close down the emulator for it to work.
