ProviderCaller <-- BinderProvider
note over ProviderCaller,BinderProvider
这条call调用属于跨进程调用，
BinderProvider左边的方法调用均位于VA主进程(main process，进程名io.virtualapp)
右边的BinderProvider个ContentProvider，位于服务进程(server process，进程名io.virtualapp:x)
当ProviderCaller首次调用call时，Android系统会创建服务进程，启动ContentProvider,
并调用BinderProvider.onCreate方法。
