Timers not running when screen is turned off / device is locked in iOS

由 ☆樱花仙子☆ 提交于 2020-01-04 02:56:10
问题 The app is in the background and it receives a callback upon disconnection with the BLE device, after which the app has to wait for sometime(1minute) and then execute some piece of code. The app behaves as expected even when in the background if the screen is turned on. But if the screen is turned off then the timer is not working and the app is not executing as expected. This is the code in AppDelegate to start a timer in background: func startTimerWith(timeInterval: TimeInterval) {

问题 I am developing an iOS app to monitor iBeacons. It works well in both foreground and background. I also need it to keep monitoring even when the screen is off. Now my problem is, when I turn off the screen with the shoulder button, NSLog shows that the iBeacon signal goes off (RSSI=0, beacon.accuracy=-1.0) accordingly, and 10 seconds later, there is no beacon found at all, while the delegate method locationManager:didRangeBeacons:inRegion: is called continuously. It seems that the app is

Obtaining sensors data while the screen is off (Android 4.0+)

问题 As far as I know on Android devices there is no 100%-sure way to get the data from device sensors while the screen is off. There are some workarounds, but they do not work always. But all the posts I read were describing Android versions ~2.2. Does anyone know whether the bug was fixed in Android 4.0+ ? 回答1: This WakeLock works like charm. 来源： https://stackoverflow.com/questions/11612065/obtaining-sensors-data-while-the-screen-is-off-android-4-0

Android notification manager doesn't work with the screen is off

问题 I have a count down timer that when it goes off (to zero) it checks to see if the app has focus. If not it launches a notification in the notification bar. When you click on the notification is re-opens the app. Now all of this works fine but if the screen happens to go off, the timer keeps going and the notification is available at the right time but never actually vibrates or rings until i turn the screen back on. Then it displays the notification like it was waiting in a queue or something

Recognize volume button presses when screen is off Android

由 霸气de小男生 提交于 2019-12-06 07:18:05
问题 I am trying to recognize when the user presses the volume rockers when the screen is off to update an activity. From what I've read, BroadcastReceivers (I think) don't work when the phone is asleep, and so the only way to do this is to keep the activity running using a PARTIAL_WAKE_LOCK. My app is a basic one that shouldn't use too much battery, but I'm concerned that using a PARTIAL_WAKE_LOCK might drain the battery (which defies the purpose of recognizing button presses when the screen is
