我追踪了
的地址#02 pc 0004a8ef /system/lib/libandroid_runtime.so (android::sp<android::InputChannel>::~sp()+10)
#03 pc 0005951f /system/lib/libandroid_runtime.so
发现崩溃发生在framework / base / core / jni / android_view_Surface.cpp的nativeUnlockCanvasAndPost函数中。 在此函数中，它声明了Surface的局部变量，当函数退出时，系统删除局部变量导致删除指向InputChannel的强指针。 我检查了logcat并找不到任何可疑点，WindowMnager，InputManager，InputReader，InputDispatcher已经启动。 我尝试使用InputChannel_test命令进行测试，所有测试用例都已通过。
请帮我指出解决这个问题的一些要点。 提前谢谢
