I am trying to install an apk file on my Android device using ADB with the following command:

E:\adt-bundle-windows-x86-20131030\sdk\platform-tools>adb install -r WebserviceA
ctivity.apk

But I get this error message:

158 KB/s (225399 bytes in 1.391s)
        pkg: /data/local/tmp/WebserviceActivity.apk
Failure [INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES]

Before put your question in stackoverflow just do some googling i'm sure you get something very useful.

Anyways,

try like this

uninstall the existing .apk

and then

re-install the new .apk

Googling your error message can be very succesfull:

It means the new copy of your application (on your development machine) was signed with a different signing key than the old copy of your application (installed on the device/emulator). For example, if this is a device, you might have put the old copy on from a different development machine (e.g., some other developer's machine). Or, the old one is signed with your production key and the new one is signed with your debug key.

So you need to make sure your application is signed with same key as the currently installed application. Note that a debug key is different from a regular key.

If you do not have your old signing key anymore, then you should remove your old application first.

  • Thank you. I get this error while installing the app on to the same emulator and haven't signed it with any other keys. – John Paul Prassanna Feb 09 '14 at 08:46
  • I can only tell you the meaning of the error message, and that is described above. Sorry I can't help you any further. – Mdlc Feb 09 '14 at 08:48
