wakelock

问题 I have a Service in my application which is designed to run every 10 minutes. It basically checks up on our servers to see if everything is running properly and notifies the user of any problems. I created this application for internal use at our company. My co-worker used the application over the long weekend and noticed that no checks were performed when the device went to sleep. I was under the impression that the Service was supposed to keep running in the background until I explicitly

问题 Posts from over a year ago suggest that it is necessary to use a WakeLock to reserve CPU to gather location information (CommonsWare in particular here Android Periodic GPS location updates with AlarmManager inside a Service). However I do not understand why I cannot simply call a Service every 28 minutes, connect the LocationClient, set a timer to wait 2 minutes, then get the most recent location, disconnect the client, and then stop the service. Because Commonsware and the user who forked

问题 I've forked the system messaging app and it is consuming the majority of my CPU, and others have reported the same. I cannot for the life of me determine why. I figured the drainage could be possibly two things (because of how much it is draining): a wakelock that has not been released, or a service doing continuous computation. Here's what I have tried: adb shell dumpsys power This shows Wake Locks: size=0 so I am assuming it is not a wakelock issue (the app uses wakelocks, of course, but I

问题 I need to make an app that keeps the screen on even when the app is running in the background. I've tried: getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); But it only works when the app is running and can't run as a service. I've also tried wakelocks but SCREEN_BRIGHT_WAKE_LOCK and FULL_WAKE_LOCK have both been deprecated. The only wakelock left is PARTIAL_WAKE_LOCK. Is there someway to keep the screen on using the PARTIAL_WAKE_LOCK, ACQUIRE_CAUSES_WAKEUP, and some loops

问题 I am writing an app and am having a bit of trouble with getting my Alarm BroadcastReceiver from starting a desired intent. The code is as follows: public void onReceive(Context context, Intent intent) { Log.d("Alarm:","Running WakeLock"); PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE); PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, ""); wl.acquire(); WakeMe.wakelock = wl; Log.d("Alarm:","Running Intent (Service)"); Intent i = new

问题 I am developing a native android app that run a backup operation every 30 mins. I am using AlarmManager for this purpose and it works fine. Here is the code I am using to start the alarm: public static void startSync(Context context) { alarmIntent = new Intent(context, AlarmReceiver.class); pendingIntent = PendingIntent.getBroadcast(context, 0, alarmIntent, 0); manager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); // int interval = 3600000; int interval =30000 ; manager

问题 I want to automatically check for an internet connection every x minutes and send data to a server. However, the following (minimal) code gives a warning in Eclipse, saying that the release() call is not always reached. PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE); PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, ""); wl.acquire(); // check active network ConnectivityManager cm = (ConnectivityManager)context.getSystemService(Context
