binder编译error
1、自己写个binderservice，编译老是报错
make: Entering directory `/home/leaves/android/android2/android'
target thumb C++: libTestBinderServer <= frameworks/tv_print/services/TestBinderServer/TestBinderService.cpp
target SharedLib: libTestBinderServer (out/target/product/generic/obj/SHARED_LIBRARIES/libTestBinderServer_intermediates/LINKED/libTestBinderServer.so)

应该是没有实现BpTestBinderService,而是只实现了BnTestBinderService及TestBinderService
2、
error: cannot allocate an object of abstract type 'android::TvssService'
这个应该是由于在基类中申明的虚函数，在派生类中必须继承并实现，有虚函数没有实现或者参数不一致造成的。
