Definition

A wake lock is a mechanism to indicate that your application needs to have the device stay on.

Remarks

A wake lock is a mechanism to indicate that your application needs to have the device stay on.

Any application using a WakeLock must request the android.permission.WAKE_LOCK permission in an <uses-permission> element of the application's manifest. Obtain a wake lock by calling PowerManager#newWakeLock(int, String).

Call #acquire() to acquire the wake lock and force the device to stay on at the level that was requested when the wake lock was created.

Call #release() when you are done and don't need the lock anymore. It is very important to do this as soon as possible to avoid running down the device's battery excessively.
