bluetooth, nfc, radio and shell are not explicitly declared in installd.te. This prevents applications in those group from upgrading by "adb install -r". You can reproduce the issue by following step: 1. adb pull /system/priv-app/Shell.apk 2. adb install -r Shell.apk 3. install failed with the error log blow [Error in logcat] E/installd( 338): couldn't symlink directory '/data/data/com.android.shell/lib' -> '/data/app-lib/com.android.shell-1': Permission denied E/installd( 338): couldn't symlink directory '/data/data/com.android.shell/lib' -> '/data/app-lib/Shell': Permission denied [Error in dmesg] <5>[ 112.053301] type=1400 audit(1387412796.071:10): avc: denied { create } for pid=337 comm="installd" name="lib" scontext=u:r:installd:s0 tcontext=u:object_r:shell_data_file:s0 tclass=lnk_file This operation fails only if the app belongs to any of the groups specified in the commit title.
