/dev/input/path to the hardware input device node named Event[number]. These nodes are related to the specific hardware, so it is possible that the specific node name of each device is different, such as in my mx3/dev/input/event0 for Mxhub-key and/dev/input/event1 for Gp2ap. Specific node information can be viewed through the GetEvent tool provided by Android, i

This is seen on a foreign site, the analysis is good, the original text is as follows:Why does the iPhone require less RAM than Android devices?There is people fight when it comes to comparing the Android devices vs IPhone. Iphones is the expensive than Android devices even with the same specifications. However, the IPhone works a lot smoother and faster than an

Android Device ManagementAndroid2.2 provides support for enterprise-class applications through the Android Device Management API. The Device Management API provides device management features at the system level. These APIs can be

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

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 data in sdcard, but to 2.3) and a series of

Due to work relationships, attention to Android will shift from FWK (Framework) to BSP, that is, Linux Kernel. In the five years at work, I have studied kernel several times, but I have never had the right opportunity or motivation to study it in depth. How can I leave this opportunity? In the past, we used to work with kernel and always felt that there were no suitable devices. After several days, I plan to start with the

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

Last time, I was initially exposed to the mounting problem of Android USB client, so I wrote the first article about the feelings. There are still some problems in many places, some of which are not clear enough, so I want to continue writing. First, the last verification shows that the device can be mounted, but only one storage device can be mounted at a time.
