sdk自带的softkey输入法ap如何打断点，为何apk装载成功后输入法进程就消失了

UserLogin是自己写的ap，sdk自带的contact也有断在断点处，

userlogin进程没有消失，打的断点处可以断（断点主屏的activity处的onCreate）
这个是sdk自带的softkey ap，

但是输入法进程此时消失了，打的断点仍旧在，但是软键盘出来后没有断在任何一个断点处，（断点是onCreate，onCreateInputView，onCreateCandidatesView，onStartInput，onStartInputView）请问，输入法作为服务，没有activity就没法打断点吗，作为单独的一个ap不可以debug吗？
