    adb shell instrument -w -e class com.lewa.security2.holder.clearanceholdertest     com.lewa.dunit.test/android.test.instrumentationtestrunner 

it never return result.

but when remove "android.uid.system", works

can 1 me ?

a unit test in android need run after kill application. applicaions shareduid android.uid.system cannot killed in way. so,you need force close application before run unit tests.
