My WakeLock isn't keeping my device awake.
In OnCreate() I've got:
CODE:...............
Then:
CODE:........
The screen turns off before the timer finishes, how can I make the screen stay visible?
mWakeLock is a field previously declared like so: private PowerManager.WakeLock mWakeLock;
My device uses Android 1.6. I would really appreciate any help to resolve this.

I have a service that acts a download manager, downloading files in the background. I have aquired a partial wake lock while the downloads are going. When the downloads finish, I manually release the wakelock. Because I am paranoid, I acquired the wakelock also with a timeout. The problem I am seeing is that if I have already manually released my wakelock, when the timeout period expires an error is presented to the user (and adb logcat shows an under-locked wakelock exception).
Is there any way to use a timeout (as backup wakelock release in case the app force closes for some reason) without getting this error?
I have a problem with acquiring a WakeLock. It seems not to work. I am trying to acquire a FULL_WAKE_LOCK but neither the display gets enabled nor is my app able to perform tasks.
I am using the following permission: android.permission.WAKE_LOCK
My acquire code looks like this:
CODE:...........
What am i doing wrong?
Added another flag ACQUIRE_CAUSES_WAKEUP ... but no changes in behavior
All i am trying to do is, to play music and to wake my device up upon a certain event. The music is working perfectrly but the device stays black.
The new IntentService in Android 1.5 looks excellent for handling AlarmManager-initiated broadcasts for scheduled WAKEUP work...except I can't see that it uses a WakeLock anywhere, either in itself or Looper/MessageQueue.
Does this implicitly hold a WakeLock that I'm not seeing? Or would I need to create a WakingIntentService that has an active WakeLock so long as there are messages in the queue?
I'm just wondering if I do this correctly; I'm programming a notification app which can display a notification when the phone is sleeping
Disable keyguard lock. Aquire a wake lock. show notification. Set alarm for timeout and reenabling keyguard and release wakelock is the user dont touches the screen. 4.1 User touches the screen, and I disable the timer. Do nothing more. Done and done 4.2 User dont touch the screen, so reenable keyguard and release wakelock. Phone sleeps again
Basically I'm wondering about point 4.1 the most. cancel the pendingintent for the alarm, and do nothing more? or should the keyguard and wakelock that are set be dealt with in some way?
I am trying to use a service to control a wakelock so I can permanently leave the screen on when my application is running. I create the wakelock and activate it in onCreate() and release it in onDestroy() however I get the error "wl cannot be resolved".
Can someone explain how I can get over this? Code below:
CODE:..................
I have a signal that puts my app to sleep for a given number of minutes (using AlarmManager) and then wakes it back up.Everything is working except the screen doesn't ever come on.I then release the wakelock when I'm sure that my app is up and running and connected again. However, the screen never comes on! The app only actually comes back to life when I hit the power button to wake up the screen manually.I'm developing on an HTC Hero.

The widget is waken up using an AlarmManager (the update interval is chosen by users, ranging from 30 mins to 2 hours) to grab some data from the Internet and display it on the widget. I do not hold a wakelock since if the phone sleeps, just let it sleeps. There's no way to update the information since nobody will see it. If I put the phone in the basement (has no wi-fi or cell signal) for about an hour. the phone will definitely not update anything. However, when I get it back from the basement, the cell network could never be recovered again no matter how long I have waited (it just get an X on the cell signal icon on the notification bar) that I must restart the phone. May I know if a partial wake lock must be held on checking network availability?
Find the code skeleton as below:
CODE:.................
I have a service which, when started, does some stuff (like downloading files) typically taking about 2-3 minutes.
If I start this service and then immediately use the power button to switch off the screen, then I would expect the phone, at some point, to fall asleep. But it never seems to fall asleep while the service is still doing its stuff. At least, not on my Nexus One.
I'm not using a wake lock (though I do use WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON in the activity that monitors the service progress).
So is it true that I don't need to use a wake lock?
I have the following code in Oncreate of my activity:
CODE:.......................
I have a service that needs to write some data to the internal storage using RandomAccessFile. Do I need to use a WakeLock to make sure the data won't get corrupted if the service process gets killed?
View 14 Replies View RelatedI'm trying to implement a times WakeLock in my Application, so this is not a Service.
I want the wakelock to simply prevent screen dimming for 3 min. Looking through the docs, this seems simple enough, but I seem to randomly encounter a Under-Locked exception that I cannot pinpoint.
Here is my WakeLock-related code:
in onCreate: PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE); mWakeLock = pm.newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK, TAG); // Adjust time to include user's setting int timeout = WAKELOCK_TIME - Settings.System.getInt(getContentResolver(), SCREEN_OFF_TIMEOUT, 0); if (timeout > 0) {mWakeLock.acquire(timeout);} ...
in onDestroy: if (mWakeLock != null && mWakeLock.isHeld() == true) { try { As you can see, I wrap the release and try to only execute it when necessary as a clean up only. I'm assuming that since I'm aquiring with a timeout, the PowerManager will handle the release in most cases when the timeout expires.
I don't have a copy of the logcat at the moment, but what seems to happen is I get the Under-Locked exception randomly, and at random times (it's not always when WAKELOCK_TIME elapses). The strange thing is that the exception does not point to my code - all the entries point to "internal" Android code.
It's hard to find examples of other people using aquire with timeouts. Any ideas what I could be doing wrong here?
I have a timer that schedule a task to run every 5 minutes. This task send a request to a server, so I need to be sure that CPU is on so that wifi or 3g can be used.
So the first thing I do in my run() method is :
CODE:.........
And the last thing I do in the run() is : wl.release() ;
I would like not to release here to be sure my service will run in the next 5 minutes :
The question is : if the device is already in a sleep state, can I wake up it with my wl.acquire() ?
Is it possible for a program to effectively and efficiently use partial wakelock without burning through a lot of battery? Tango, for example? I'm trying to decide if the partial wakelock usage is worth the video call ability.
View 1 Replies View RelatedI'm developing an sms receiver, and i have included a KeyguardManager and a PowerManager to be able to disable the keyguard and turn on the screen if user would like to. This works great, but only once.
When a message is received, the keyguard gets unlocked and the screen is turned on, and it gives out a sound and vibration. But if i don't read the message right away, but let the device power off by screen time out, and i then receive another message while the last one is not read, the device does not turn the screen on again, and it does not give out a sound or vibration, until i turn on the screen manually, then the sound and vibration comes.
If i close all received messages, then my app is able to disable the keyguard and turn on the screen and give out a sound and vibration when a new message is received.Here is my code that is run when the keyguard should be unlocked and the screen should be turned on.
Code:
private void disableKeyGuard()
{
KeyguardManager km = (KeyguardManager)getSystemService(KEYGUARD_SERVICE);
kl = km.newKeyguardLock("SMSHandler");[code].....
I have a N7 2013 on stock KRT16S, and my biggest wake lock is AudioMix.
I'm rooted, using Greenify, and I even have Google Search uninstalled. I am not using GEL. People suggested turning touch sounds off, and I tried that too, but it didn't work.
what is this AudioMix wakelock? Is this like Audio_Out2 on the Nexus 4? Keyboard sounds or any sounds = wakelock? I also find it odd that considering I use my phone on vibrate 98% of the time, that the on my Nexus 4 and older phones, the speaker turns on when I press any button my phone. I thought system sounds wouldn't turn on? Quite interesting. Even in silent mode, the speaker turns on. I know this because my Nexus 4 speaker used to crack everytime it would turn on. To me that's an unnecessary wakelock that should ONLY happen if you're not in silent or vibrate."
I want to generate a wakelock when my screen goes off and then release that wakelock 20 minutes later. I can't find an app that will do this for me. Is it possible with Tasker and if so, how??

I'm getting beat down with GTALK_ASYNC_CONN wakelocks while on my work's AP.... the specific WL is :gtalk_async_conn com.google.android.gsf.gtalkservice.androidendpoint.... something everyone has been complaining about recently, and I never saw it until recently (now that I got up to 4.1.2 a short time ago.
Is there a way to determine exactly who is generating that WL? It's not related to GTALK, as the WL name incorrectly leads us to believe, but it must be google, and I only see it fire when the Wi-Fi is connected and in use. It's non-existent when I'm on Mobile. It comes and goes, sometimes chugging wake time like its cheap beer, othertimes it's dormant, and I haven't been able to figure out who is using it based on the context of when it occurs.
There HAS to be a log or something somewhere that says process X is responsible.
I'm using Wakelock in my application to prevent the phone from sleeping when the app is visible. The problem comes when there is an orientation change and the system destroys and re-creates the app in landscape mode. If the wakelock timer has expired in the background the system takes the release of wakelock as an opportunity to switch off the screen.
Edit: I should mention that I am setting Wakelock onResume, and releasing onPause - as I understand it, it's necessary to release then to prevent the app from leaking the wakelock. I need wakelock to continue through the orientation change. Below I've outlined a solution to this. Is this the preferred way to handle it, and are there any alternatives?
Create a service which holds wakelock (rather than the activity) and when the activity unbinds the service starts a countdown timer (for say 10 seconds) in which it will release wakelock when the timer expires if the activity does not rebind. If it was a simple orientation change the activity will rebind within that 10 seconds and so maintain wakelock, if it doesn't, wakelock will be released.
I'm searching for android phones that can use video out to the tv for a research project. I'm considering the HTC Touch Pro.
Is there anything I have to do specifically to get the video out to work (for displaying my app on the tv)? or will the phone just display a running app on the tv without extra work?
I have google voice and use it for every phone call I make. I heard that there were issues with several gvoice updates, so I haven't updated google voice since 0.2.8 and it is working just fine- every call connects, no problems. Is it worth updating to the newest version of google voice with push? For those of you with 2.1 on your Eris- does google voice work for you?

Of the apps I've downloaded, only a few of them have worked. Of those few that work, some don't work right. Has anyone had problems with these apps crashing on them, or just not working correctly?
- Nice Battery (see description at bottom of: My Ultimate CLIQ settings (so far))
- WeatherBug (kept showing the wrong location, crashed when trying to change location)
- Snake - doesn't work just says its "paused"
- RingDroid - crashes when I select the "Facebook Pop" button
- Layar - screen is rotated 90 degrees at all times
There have been others, but usually I just uninstall them right after discovering it doesn't work right.
I've had an HTC Desire on Orange in the UK for about 6 weeks and it is having persistent problem. Firstly despite having a strong 4-bar out of 4 signal, online services and the internet do not work at all when a 3G signal is being received (e.g. news, weather, all widgets, internet, email etc).Calls and texts do work however with a 3G signal.But when a 3g+ signal (HSDPA) is being received, all internet services as above work fine.However, when a 3+ signal is being received, the phone does not make or receive calls or text messages, and often fails to send texts. Calls I make immediately shut down (bleep + �call ended�), and incoming calls from other people go straight to answerphone. Also often when turning the data connection on/off, it freezes and has to be rebooted, and turning airplane setting on and off does not fix the problem.
I have also tried the different network settings (GSM, WCDMA, auto, etc). �GSM� sends and receives calls and texts but doesn�t work (or is incredibly slow) with internet, and �auto� and �WCDMA only� show the problems as above.I don't think this is a network/coverage issues as, as I have seen many people reporting these same issues on other networks and in other parts of the UK, and I have read that other people are having to manually turn off HSDPA to be able to make calls (using an app?). Even if I can stop HSDPA from connecting to make sure the phone works, I still can�t use the internet at all on 3g � even GSM works better!
Finally, when I connect to a bluetooth device (e.g. car and headphones) the phone will connect briefly, and then randomly disconnect. I have also seen this issue reported elsewhere.I very much like the phone and don't want to get rid of it, but these problems are making the phone unuseable.Also I don't know if I should be contacting HTC or Orange about this. Will the upcoming Android 2.2 fix these problems?Anyone know how to fix this or if I need a new handset? Are there any apps that can help? Also does the Nexus One have these problems and are they fixed by Froyo?
So I made a discovery - my dialpad doesn't work during a call. Even if I bring it up via the softkeys, the numbers don't register a tap...anyone. else have this issue or is it just my phone?

a) Speaker doesn't work in call (very weak). works well in ringtones etc.
b) Scrolling contacts by letter doesn't work.
Other than that this is a leap forward, especially with the overclock options!
Both bugs, as well as others, fixed in 1.6.3.1 update!
Ive had Qik on my Symbian and it worked like this, I go in app on my phone and start recording and that is immediately transfered on my profile qik.com/XYXYXY, so everyone who is on that webpage sees what I am recording in real time. How does it work on Android with Qik app ? I go on my profile but no video is showing ? And whats up with that "Sharing" option ?? It takes names and phone numbers from phonebook ? I dont get it how is that sharing when you can see videos only on qik.com/XYXYXY website ?

So here's my situation: I work at a calling center where internet access is blocked off. I have my own cubicle and get my own computer But they have blue coat Web filter And i lack Administrative So i can install only very limited programs. I've tried starling the android sdk But to no avail. I've thought about tethering too but i'm not sure if that will work Since i don't know if a computer.can maintain more than 1 internet connection. Basically i can't have my phone out while at work, so i need to figure out a way to use my phone to browse the internet on my computer screen without being obvious.
