wakelock

Is it possible to override the functionality of the android power button ? I want to 'disable' the power button. My plan is to override the functionality of this button to do nothing ( {}; ) Well my main idea is to disable the turning the screen off. I want when someone press the power button nothing to happen. How can I do this ? Is it possible to override the functionality of the android power button ? I want to 'disable' the power button. Fortunately, this is not possible, except perhaps via custom firmware. It works on Cyanogenmod: http://review.cyanogenmod.com/#/c/18924/4/core/res

I have this application that needs to run a service (background) that beeps periodically. The phone needs to beep the entire day for 5 seconds every one minute (used a handler in the service). I have implemented this service which does this perfectly, but when the phone goes into deep sleep mode, the execution stops of this handler stops. Using this answer from the question in SO, I managed to use wake locks and it works fine. But when I explicitly put the phone in deep sleep mode, the handler stops executing. Where do I place the wakelock in the service. Code snippet below. public class

I have an activity that needs to turn screen on(if offed) when it is started. So in onCreate, I have: this.getWindow().setFlags( WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON | WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON, WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON | WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON); Using this with help of wakelock in broadcasr receiver , I am able to cause my activity to display whenever it is started from broadcast receiver. But problem is very strange

I have a service running for my application to send notification every hour. This is working fine as i heard a sound and a vibration every hour because of my notification but i also want that my notification light up my screen as well. But i am unable to light up my screen when notification appears. Pradeep Sodhi PowerManager pm = (PowerManager)context.getSystemService(Context.POWER_SERVICE); boolean isScreenOn = pm.isScreenOn(); Log.e("screen on.................................", ""+isScreenOn); if(isScreenOn==false) { WakeLock wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK |PowerManager

I am very confused whether to acquire this wakelock. E.g. I have this type of code that is called from onReceive() of a BroadcastReceiever (CONNECTIVITY_CHANGE, BOOT_COMPLETED etc) asynchronously i.e. I am launching an IntentService from onReceive() which performs heavy lifting. private static void insertInDatabase(Context context /*, some data to be inserted in database*/) { Database helper = Database.getInstance(context); PowerManager pm = (PowerManager) context .getSystemService(Context.POWER_SERVICE); final WakeLock wakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, wakelockName);

Can somebody explain what the exact difference is between BroadcastReceiver and WakefulBroadcastReceiver ? In what situations would we have to use each Receiver class? Mehul Joisar There is only one difference between BroadcastReceiver and WakefulBroadcastReceiver . When you receive the broadcast inside onReceive() method, Suppose, BroadcastReceiver : It is not guaranteed that CPU will stay awake if you initiate some long running process. CPU may go immediately back to sleep. WakefulBroadcastReceiver : It is guaranteed that CPU will stay awake until you fire completeWakefulIntent . Example:
