Hi Thanks firstly. Both project is running. In fact B is running, I try to instaniante A from B which lies in different apk. but it failed. The type should be "com.example.test".(Just a guess, I'll confirm tomorrow) Regarding "Is framework/base in project A or B?" , I think both. When I put com.example.test to framework/base(which mean extend android API), it works. Regards, Jove
