I am sure it is buried in the SDK somewhere but I couldn't find it. This is relevant to a service running in the background: How can I find out if the device is in sleep mode?

I apologize if these topics were already covered in previous threads.I wasn't able to find anything related in my searches. Auto-rotation for keyboard when answering a text message received in sleep mode does not work. If I actively send a text when phone is already awake, keyboard rotates with no problem but when I go to reply to a text that I received while phone is in sleep mode, the keyboard does not rotate. Is this the norm?I am also experiencing a delay when the I wake the phone. After unlocking the phone, I used to go straight to my home page, now I get a "loading" message which takes several seconds. Is this due to the number of apps I have loaded? Is it possibly due to number of photo frames I have on my home screen or the complexity of the wallpaper?

View 3 Replies View RelatedI'm trying to find some official android documentation that discusses sleep mode, with a focus on issues that might be of relevance to app developers. For example, things like:
1. What causes a device to enter / exit sleep mode?
2. How are running processes impacted when the device enters sleep mode? (I believe they continue to exist, but don't execute because cpu activity is suspended. When the device wakes up execution picks up where it left off?)
There is some good info in the API docs for PowerManager and WakeLock, but nothing there that explicitly states what I have assumed in point 2 above. Are the above issues (and any other relevant issues) documented anywhere?
I'm really not "using" my Android S3 phone all day long, it gets frustrating when the bettery runs at 30% at 2pm, without any real use.
So the concept would be:
1) either a "ROM" of Android, which would be seriously minimal - like the device is not a smartphone - so only wake up on incoming call or text message
2) or an app, which does the same thing - suspends the phone completely, and wakes it up only on the incoming call or text message
I was just curious - does something like this exist? I don't care about apps, notifications, wifi or sync, I was thinking more along the lines of would it be possible to use your smartphone like a typical "cell phone", and when you need other apps or full features (GPS navigation with maps, or Shazam, or whatever it is you need) - you just "reboot" or do a quick switch to "full Android" mode, and use those features.
I feel that the battery life should be at least 5 days in that mode, with light usage?
Is there any way to detect whether an android phone is in sleep mode (screen is black) in the code?I wrote a home screen widget. I don't want the widget gets updated when the screen is black to save the battery consumption.

View 4 Replies View RelatedI have a service which polls a server at certain intervals. I use an AlarmManager and a BroadcastReceiver to start the service. My problem is that after a certain duration, even though the WiFi is still enabled, but for some reason, my application can't contact the server. I get an "Unreachable network" error. Note that I've already acquired a partial wake lock as well as a wifilock. Here's my code for the BroadcastReceiver.
public class ServiceAlarmBroadcastReceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
WakeLock wakeLock = null; WifiLock wifiLock = null;
try { PowerManager pm = (PowerManager) context .getSystemService(Context.POWER_SERVICE);
// acquire a WakeLock to keep the CPU running
wakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "MyWakeLock");
if(!wakeLock.isHeld()){ wakeLock.acquire();
} Log.i("ServiceAlarmBroadcastReceiver", "WakeLock acquired!");
WifiManager wm = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
wifiLock = wm.createWifiLock(WifiManager.WIFI_MODE_FULL , "MyWifiLock");
if(!wifiLock.isHeld()){ wifiLock.acquire();
} Log.i("ServiceAlarmBroadcastReceiver", "WifiLock acquired!");
context.startService(new Intent(context, ThePollerService.class));
} finally { // release the WakeLock to allow CPU to sleep
if (wakeLock != null) { if (wakeLock.isHeld()) {
wakeLock.release(); Log.i("ServiceAlarmBroadcastReceiver", "WakeLock released!");
} } // release the WifiLock if (wifiLock != null) { if (wifiLock.isHeld()) { wifiLock.release();
Log.i("ServiceAlarmBroadcastReceiver", "WiFi Lock released!"); } } } } }
I just got an evo a couple weeks ago. I love the phone, but after I downloaded the OTA, it won't go into sleep mode. I've turn off all the syncing, tried task killers, tried stopping google talk, the calender, everything I have read in forums.I am thinking my only choice may be to root, but I wanted to see if anyone else had this problem and if anyone actually got it fixed.I really don't want to risk bricking my phone if I don't have to..
View 4 Replies View RelatedSo, I have left my almost fully charged Evo on my nightstand the past couple of nights without plugging it in, and when I wake up in the morning, my battery is almost fully drained. One night I did have the 4G on, but the other night I did not. Is there some sort of setting or sleep mode so it doesnt drain the battery when I am asleep?

View 5 Replies View RelatedI was investigating the issue of setting up a delayed activity/event, that will occur and trigger even if the phone is in sleep mode (wake up, do what you need to do, go back to sleep). I was thinking of the following methods: 1. sendMessageDelayed 2. Timer 3. AlarmManager.The basic requirement is to be able to set a triger in the future, and be sure that this trigger wakes up the system if it is sleeping,perform the task, and go back to sleep.A partial wakup is required (no screen flickering). Currently i'm using the sendMessageDelayed, and i keep a wake lock held for the timeout period (bad practice).

However a new software upgrade has meant when it's recording it tells you on the home screen if you press the button to wake it up, even if locked. Does the android have voice recording in sleep mode and if so does it do so without it stating it on the screen?

View 2 Replies View RelatedAs the phone sits idle, the screen goes black. In order to use the phone again you must hit the power button, then slide down on the screen or hit menu. Is there anyway to remove the phone from sleep other than hitting the power button? I find this incredibly annoying that I can't just tap the screen then slide down. Are there any other options for removing it from sleep mode and if so where would I change it?
View 2 Replies View RelatedWhat is a good way to find what app is causing the phone not to sleep. I charged the phone last night while on, unplugged this morning and according to Spare Parts, my phone has been running 100%. I've also got System Panel Lite and Battery Left, but I'll be damned if I can't tell what the offending app is. Battery is on Smart Mode, Time Outs are set to 15 min for both Off Peak and Peak.
Good news is 9 hours 36 minutes and I'm still at 50% with an extended Battery and I've done quite a bit of Market searching and downloading, had a few phone calls, sent a few texts, checked the news widget, checked emails, and checked the old facepage a dozen times. (slow day at work)
Anyway, anyone have a good way to check for offending applications?
Over the last week or so I've been obsessed with trying to get my hero into sleep mode, in order to save battery. For those who don't know about this, there are many threads around the net telling of a fix for the messages bug, which prevents the phone entering sleep. It's supposed to reduce CPU usage, thus saving battery.
Now, I've followed the methods of many people who claim to have done this successfully, down to a tee, but for the life of me, I can't get it to work. For some reason my awake time is always at 100%. It's now at the pont of driving me mad, and I'm just wondering if anyone else has tried and failed to do the fix. If anyone needs background info on this problem, I'll post a link up later, as I'm sending this via my phone at the minute.
I have just got my HTC desire. And i cant stand that i have to press the power button to get out of sleep mode to show the lock screen. wish i could just press menu/home or any of the buttons but the power one right at the top. I only say this as i swear my htc tattoo unlocked in this way. if not this could get quite annoying. So is there anyway to change this. I have tried looking through settings but i have a bad feeling you cant change it.

View 3 Replies View RelatedI just bought the phone, and have been charging it for a half hour or so, and it keeps shutting off(or going in sleep mode) while I am trying to set it up.
My first thought is that it needs to charge; I admit, I barely let it charge right out of the box because I am so anxious to use it. Is that the issue? I assumed that even if the batter is at 5-10%, shouldn't it work without issue if it is plugged in to the wall and charging? I will let it charge another hour or so, but I just cannot wait to get my hands on it.

View 4 Replies View RelatedI have a smartq t20 tablet (great cheap tablet!) running ICS, my question is, when I leave wifi on all the time, what happens when the tablet goes to sleep (not awake according to the battery details)?I can leave a download running and it would continue when the screen is off, does this mean my tablet is never going into deep sleep? Or is that unrelated?
I know the wifi itself drains more battery when left on even if it isn't being utilized but I was wondering about the CPU side of it.
My app seldom needs to put the device (or screen) to sleep. That is - programmatically imitate user pressing on red stop-call button. According to docs PowerManager.goToSleep() does just that, but requires android.permission.DEVICE_POWER, which is never granted to apps!
(A) What on earth should I do to get this working?
(B) How can I programmatically wake up the device.
just to clarify - I'm not interested in a wake lock solution.
