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

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

Every time I use a USB cable to plug in the computer interface will prompt "device can improve performance" small series always want to know the reason. Today, when I go to the forum, I understand, share to everyone is because your motherboard USB port is different has 1.1 of 2.0 of 3.0 because you plug in the USB port is relatively low so there will be a hint you can ignore him can also be inserted into the other mouth to try to plug in a better mo
