If so, call the svcmgr_handler function to handle the requests.Service Registration Let's take a look at how ServiceManager registers the service. First, when there is a request for service, the callback function svcmgr_handler called: Int svcmgr_handler (struct binder_state * bs,Struct binder_txn * txn,Struct binder_io * msg,Struct binder_io * reply){Struct svcinfo * si;U

Recently, there was a need to get the MAC address of the Android device on the JNI layer. Google circled it and did not see the implementation method. So I had to write it myself. The basic idea is to call the android Java-layer API through JNI to obtain the MAC address of wifi. Theoretically, all JavaCodeCan be translated into JNI code, so it can be implemented. First, let's take a look at the Java implementation code obtained from the MAC address: PublicString getlocalmacaddress (cont

Because the device files are created through device_create in the kernel driver, the device files created by Device_create are only read by the root user, and Hello_device_open is typically called by the upper app. These apps typically do not have root permissions

Spring for beginners in Java sshIn this article, I learned two ways of dependency injection: Set Value injection and construct injection. In our previous thinking, if we call a class, we need to manually instantiate it. When we create a called job that does not need to be completed, this is the control reversal, when the called instance process is completed by Spring and injected into the caller, this is dependency injection. I. First, let's learn how to set value injection. First, we will creat
