0 Jelly Bean adb install *.apk Failure [INSTALL_FAILED_INVALID_APK]

If you have been moved recently to Jelly Bean and you use stock kernel(check kernel version on the screenshot) you might have some strange problems with adb and install command.

Every time I tried to use adb install test.apk on my i9300 I got Failure [INSTALL_FAILED_INVALID_APK].

The solution for this this problem is very simple,just change your kernel!
Seems like stock kernel have some strange issues,

1 Cyanogenmod 9 (CM9) for Galaxy S3 i9300 Stable Release

Cyanogenmod team finally released CM 9 stable version tonight!!!
That means that CM 9 development is finally finished and that CM team will focus solely on Jelly Bean(CM 10) and maintenance of the CM 7 codebase.

From CM team blog :

 "Many have wondered why we bothered to finish CM 9 when we are already active in CM 10 development. To that, our answer is: we don’t like to leave things incomplete. There is no profit gained from what we do, so the satisfaction of completing a goal is our only reward. This release also serves as a release suitable for the masses, especially those who won’t have 100% functioning releases of CM 10 immediately or are averse to anything branded as ‘preview’, ‘alpha’, ‘beta’ or ‘nightly’." 

You can get Stable CM9 for Samsung Galaxy S 3 i9300  (only international version) from here and the latest  gapps(google apps pack) here.

Known disadvantages :

- Camera app is very basic (Stock one is better,for example can't take photos while shooting video & e.t.c)
