How to deal with INSTALL PARSE FAILED INCONSISTENT CERTIFICATES without uninstall

Question

I tried to reinstall an apk   adb install -r new apk   And it shows the error   Failure  INSTALL PARSE FAILED INCONSISTENT CERTIFICATES    One solution is to uninstall and install the new apk  that works fine   But I m wondering whether I could re-build an apk and re-install without the uninstallation  Eg  change some config in the AndroidManifest xml  or not sign the APK  etc   It would be great appreciated if you could tell me the whole meaning of the  INSTALL PARSE FAILED INCONSISTENT CERTIFICATES

I faced an another use case where I got the similar error. When At first I got the error, I panicked, and removed /data/data/{package.name} After that I tried, and my problem was still present. Then I tried uninstall, it failed.

I then removed the apk file present in /system/app (required root access), and tried uninstall and it was successfull.

After that I tried re-installing the apk, it worked.

Nothing from above worked for me  The problem for me was that I had wrong source in my Java Build Path for android-support-v7-appcompat  When you go to Project  Build Path  Configure Build Path   Under the Source tab make sure you have android-support-v7-appcompat gen   android-support-v7-appcompat libs and android-support-v7-appcompat src and nothing else  Click  OK and it should work

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

If you encounter a failed deployment to an Andorid device or emulator with the error  Failure  INSTALL PARSE FAILED INCONSISTENT CERTIFICATES   in the Output Window  simply delete the existing app on the device or emulator and redeploy  Debug builds will use a debug certificate while Release builds will use your configured certificate  This error is simply letting you know that the certificate of the app installed on the device is different than the one you are attempting to install  In non-development  app store  scenarios  this can be indicator of a corrupted or otherwise modified app not safe to install on the device
