Android build successful but apk not functioning on android device

[Deepak Kumar]

Hi, I generated a keystore using android studio and added keystore certificate in project properties while triggering android build,i did not trigger build from the same system where keystore was generated at the first place. build was successful but apk generated was not functioning i.e login button was disabled, app was tested to be working fine on simulator before the build. Then i triggered build from the system where keystore was generated at the first place, build got successful and app was functioning well, but after that i given 5 to 6 builds from the same and different systems and work spaces but same issue is arising every time, build successful but app is not working, login button is disabled, can anyone tell whether this problem occurred because of adding certificate to generate signed apk, i tried removing the certificate and triggered debug build, still the same problem occurs, please tell me solution to this problem.

Hi,
a certificate problem will prevent the app from installing. If you have a problem in the initial form it's something else.
Did you test on a modern Android skin?
Did you try looking at the device logs via DDMS?
