For example, a telephony app could turn off the device's screen when the app detects that the user is holding the device close to their body. The app uses the device's proximity sensor. For example, an app could display one of two different color schemes based on the ambient lighting conditions. By using this sensor, an app can detect more smoothly whether it needs to switch between portrait and landscape orientations. The app uses the device's gyroscope to detect rotation and twist, creating a six-axis orientation system. For example, a navigation app could show the current direction a user faces. The app uses the device's magnetometer (compass). For example, a weather app could report air pressure.
The app uses the Global System for Mobile Communications (GSM) telephony radio system. Allows applications to open network sockets.Īllows applications to access information about networks.Īllows using PowerManager WakeLocks to keep processor from sleeping or screen from dimming.Īllows an application to receive the ACTION_BOOT_COMPLETED that is broadcast after the system finishes booting.
