wakelock

问题 I have a service that executes in 2 phones. They communicate with each other using sockets and execute some script (which may take 1-2 minutes approx.) and exchange files (using HTTP Post) between them. I want this execution to continue, even when the screen is off, i.e acquire a Wakelock. I saw this link, but I'm not sure where to incorporate this in my code(as the device may sleep in the mid of execution). Any guidance is highly appreciated. Thank you. 回答1: I m using same app for 2 phones.

问题 I have created an android app which runs fine in all phones. But in my Alcatel phone it doesn't as the phone goes to a deep sleep mode and the data network fails so the app doesn't get a data network and doesn't sync the data from the server . My Design ... SystemBootReceiver --> (DataSyncService)Service --> (MyBroadcastReceiver)BroadcastReceiver --> (MyDataService)Service . So here on system boot I start DataSyncService where I set up the AlarmManager (repeated) and call the

问题 I have an app which is used for lets say 4 hours, but only every 5 minutes a user needs to make an input or read the screen. Putting the phone to sleep and locking the screen is a bit annoying. So I have two options: getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); which doesn't lock the screen but the screen is always bright, I would like to dim it while there is no activity. Just because of battery life span, or doesn't that matter that much for these 4 hours? a wake

问题 I am developing an app that needs to use both wifiLock and wakeLock so the audio streaming when the screen is off does not get disturbed. I have tried my app on Android 2.3 and wakeLock and looks like wifiLock work as expected so there is no difference between when the screen is on or off, but the same app on Android 4.2 (Jelly-bean) when the screen goes off is not working as well and the audio gets choppy which shows either wakeLock or wifiLock are not working correctly. Is there any reason

问题 I am trying to turn on and off the display after a certain action happens (Lets just worry about turning the screen off for now). From what I understand from wake lock, this is what I have: PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE); PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "My Tag"); When I read other posts on stackoverflow and else where, they seem to tell me that PARTIAL_WAKE_LOCK will turn the screen off. But if I read the SDK
