如果将shareduserId设置为“ android.uid.system”，则无法运行Android单元测试

Question

I got a problem when I was running a test that the target Package's sharedUserId is "android.uid.system"

when I type this in shell

    adb shell am instrument -w -e class com.lewa.security2.holder.ClearanceHolderTest     com.lewa.dunit.test/android.test.InstrumentationTestRunner

it never return a result.

but when I remove the "android.uid.system", it just works

can any one help me ?

Answer 1

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