Using Android Device Monitor to view the Data folder under the File Explorer directory, the result is blank. This problem is caused by the incorrect Linux permissions on the Data folder.Workaround: Ru

Unlike Windows and linux,android devices that don't see the mounted directory on your Mac, how do I transfer files between an Android device and a Mac computer since I can't see the Mount directory for my Android device?Original

set some handler for the qwerty2 device. As shown in figure 1, two important handler types are evdev and keyboard. Add a little output to the two files respectively. It is found that evdev has a poll function, and EventHub also calls the poll function to obtain the input event. We can see that the handler evdev transmits data to EventHub. Conclusion 3.3 This goal has been achieved, and the process for ge

To make a good Android application, it is essential to use the network communication technology, it is difficult to imagine a software without network interaction can eventually develop much success. So let's take a look at how web interactions are implemented in general Android apps, and here's an example of a Boook object: As shown above, first on the phone to generate a book object, which contains the

Device management Android 2.2 and later versions provide a set of device Management APIs to manage Android mobile phone devices, including device lock and camera disabling (4.0 and later), erase user data (also can erase the

event is clicked or double-click or long press and so on, rather than face these large and complex raw information, so, Android will be able to convert these raw data into a certain conversion for ease of use, if you need to do a driver development involving these raw data operations can also be directly accessible to its use.It can be seen that the input subsys

_ write_to_log_kernel.Look at the implementation of _ write_to_kernel (), which is basically a write operation:static int __write_to_log_kernel(log_id_t log_id, struct iovec *vec, size_t nr){ ssize_t ret; int log_fd; if (/*(int)log_id >= 0 */ (int)log_id To sum up, the println_native () operation is to open the device file (if it has not been opened) and then write data. But how to write it depend

For serial communication, the effect of setting data bit length on communication isIn the serial data communication, you will see the serial port parameter settings. Where the "Data bits" setting, there are four options, namely 8, 7, 6, 5. So how does changing this parameter affect the transfer of

During Android development and transplantation, you sometimes need to read and write a device, but the system may not provide the corresponding services. We need to develop our own hardware access service to control devices. The following example is the process of reading and writing the most simple I2C device EEPROM, I2C driver writing there are two ways, one is

On Android devices with G-sensor, the motion acceleration of the device can be obtained through the API, and the application can calculate the direction of the device from the acceleration by some assumptions and operations.The basic code for getting the device's motion acceleration is: Sensormanager sm = (Sensormanager) context.getsystemservice (Context.s
