Develop Android applicationsProgramYou may need to test between multiple devices, including emulator and handheld devices. When you need to delete an app in development, you need to use the ADB uninstall command. Its explanation is as follows: ADB uninstall [-K] ('-K' means keep the data and cache Directories) By default, this command can run normally when one device is connected. When multiple devices are connected, the following situation occur

When writing drivers, it is generally necessary to add node information to the device tree, which provides a way to add device information directly to the drive.The drive template for I²c is as follows#include The SPI driver template is as follows#include The SPI and IIC drivers under Linux are not programmed to add device information on the

Using the device's onboard gyroscope can be achieved, when you rotate the phone screen, the inside of the screen will not be updated with the view to move to balance the physical movement.The following example performs this operation using a small number of simple geometric transformations. He builds a motion manager, subscribes to device motion updates, and then applies image transformations based on the swing, forward tilt, and sway angle of the mot

is IOS6 the previous implementation, we can see that this API is a relatively low-level implementation, its callback or C implementation, rather than our usual practice of OC implementation. so in IOS6 and beyond, the API is deprecated (of course, if you still use it, you can still implement the function), we have a better and more advanced implementation to solve the problem:[[nsnotificationcenterdefaultcenter] addobserver: Self selector:@selector(outputdevicechanged:) Name:avaudiosessionr
