Nexus :: WiFi Sleeps When Device Locked / Solution For This?
Jun 11, 2010
I want you guys to test the new email notifications when the device is connected through WiFi.
For this you've to set the WiFi sleep policy to never and the Background and Auto sync option needs to be checked.
Well, I don't get any notifications. I went an extra mile ahead and pinged the IP address and found that I get "request timed out" error when device is locked and when it is unlocked, the packets are received properly.

From what I can tell, if you turn on WiFi the phone never sleeps even in standby mode. Is this a known issue or has anyone else noticed this. I noticed this using Spare Parts and turning off and on things until I saw it was wifi that keeps it awake.

I've been able to lock the screen twice with the current implementation of the app I'm writing (MediaDroid). It's very inconsistently (2 out of about 100 runs) and I'm not sure how to trigger it, so I'm assuming it's some sort of race condition or the number of threads I'm spawning.
The activity I'm working on loads a gallery of thumbnails from the sdcard. I believe I'm using most of the best practices described by Romain Guy from his Google I/O talk "Make your Android UI Fast and Efficient". I've implemented an image cache with SoftReferences wrapping my Bitmaps and created an Efficient Adapter for the gallery using the ViewHolder pattern.
What I am doing, which I question, is loading each image via a thread as it is retrieved from the ImageCache...I pass back a default image if the bitmap is null, then update the default image in the ImageViews with the Bitmap is loaded from the sdcard; I'm doing this by posting to a Handler in the Adapter from the thread that loads the image.
So as you can imagine a number of threads are created, about 25 at a time, as the user swipes through the image gallery. Once the user reaches the end of the gallery, the images are only reloaded if the garbage collector has collected them due to the SoftReference. I've been impressed by how well this worked....until the bug mysteriously started appearing. What has happened both times is, all the images in the gallery show the default images, then I get an ANR and with the force close or wait option, I hit force close and the ANR dialog shrinks (but doesn't go away) and the background goes black...then everything just freezes...here's the logs where I believe things start to lock up.
CODE:......
If I press on the screen I get nothing on the device, but in the logs I get
CODE:........
And I have to power down the device.
So if the number of threads is the problem I'm thinking of loading all the bitmaps when the app is first initiated, probably using the AsyncTask class. A question I have though about this is that the docs say that you can only call execute() once...what's happens if some of my Bitmaps are garbage collected?? Do I then call individual threads to reload? I've looked through some of the Google apps, Shelves and Photostream, but they don't seem to be using Bitmaps wrapped in SoftReferences.

I want to keep the Hero in my back pocket, replacing another phone. I carry another larger (no jokes) device in my front pocket.
The screen can turned on and unlocked (not pattern lock) by pressing the "menu" key twice. Or, "End/Power" and then "menu". In my back pocket, my @$$ apparently pushes on these buttons randomly and sometimes turn on the device.
I do not wish to use pattern lock, it's too many steps. I am used to S2U2 on WM and it's fast.
Are there any applications that can modify the behavior of the buttons or the turn on characteristic of Hero? It would be nice to disable the menu key from unlocking the screen.

I have an application that is playing audio, and I would like to allow the listener to toggle between pause and play while the screen is locked, as it is a hassle to have to unlock the screen in order to pause the audio playback. Is there any way to monitor for KeyEvent.KEYCODE_DPAD_CENTER while the the screen is locked? I have been looking through the documentation but have not found any information on how to do this.

I have a sony ericsson X10, it has a security pattern lock on the phone. However this has gone off in my pocket and now the phone is locked. I can not remember the google email address for the phone and now i can not access the phone. Orange customer service has told me to get in touch with google, in order to delete the old account [whatever that may be] but there is no number for google customer service.

Apparently the new iPhone will stay connected to wifi even while the screen is locked.This is nice because with my current iPhone,I use about 3-4 megs of data a day even if I never leave my house (which has wifi).It would be nice if the Captivate didn't do that since I have the 200-meg plan with AT&T and I'd like to use my data for web surfing, not checking for email in the background. Would anyone mind checking this for me?

I'm actually more disappointed than I am happy with the update. This is just a minor vent, ignore if you don't want to read. I'm coming from Windows Mobile. Having apps running or not, was a simple thing. With android, why does it have to be an annoyance? I understand Android handles programs in the background well esp Froyo. But why does it have to be a pain, esp for the OCD types, when you close apps you don't want running, they just open themselves again? You can go as far as going into the services, and shutting down that service, not only the app, and have that service restart itself. With 2.1, using Advanced Task Killer, the apps were closed and never really opened again. Unless I lost service or something, which for some reason triggers the internet related apps to open again.
Now I did a hard reset earlier hoping to fix some of the problems I'm having. It didn't really help at all. One problem I'm having is, my Evo NEVER sleeps. Currently synchronized at 0:52:xx Up/Awake times, restarted earlier hoping for change. 2.1, I never had this issue. And after hard resetting, I'd think it would be normal as it is the bare OS itself. Didn't work. Downloaded System Panel lite, forced closed some apps, also from settings-applications. Still same results. 2.1, I had a very good standby time when I wasn't using it.............

I"m running Win XP 32 bit, SP3. I have Nexus one device. and I develop on Eclipse. I'm trying to install my app to test it on a real device - my own Nexus one. after downloading and installing the USB driver - the devices charges just fine. after I mount the USB storage (from the device) I can even see the phone's file system from the computer (thus able to move files in and out of the SD card). however - "adb devices" command returns an empty list. also, Eclipse "Device Chooser" doesn't show the device (it shows emulators I previously configured).

I like to send back a Nexus One device and I like to ask how accurate is the build in function to clean up the device. The one located at Settings->Privacy->Factory data reset.
Is this the same with the "Delete Option" located in the recovery mode?
In general what method advance user use to clean up their device and perform a hard reset?

I have a Star A3 running 2.3.4
I am running Ttorrent Pro on the phone, and the speeds are less than impressive (everyone else says the same thing) I am on a very fast connection, using speed guide I literally max out the speedtest servers in my local area (20Mb up/down which is the max they let you go to, I would get 100/100 if my speedtest server would allow it) and I have a port forwarded correctly.
but anyways, what I have noticed is, when wake the phone, and open the torrent application the speeds are down to around 3Kbps if I leave it open the speeds immediately start ramping up to 200-300Kbps if I keep it awake.
So this makes me think, when the phone is sleeping a lot of the connections are being closed, or when the phone is asleep it won't try and open new connections to new peers (and the current peer list may go stale while its asleep)
this is with all torrents, now the exact same torrent on another PC with a DSL connection (3Mb down 300Kb up) is downloading faster than the phone.
Are there any developers out there than can explain what processes are going to sleep that may be useful to keep awake for downloading, and also what are the tcp limits on the phone, ie. max open connections, max half open etc?

I have a Nexus 7 running 4.2.2 Jelly Bean, with an unlocked boot loader and rooted. Since the 4.3 versions are now officially out, I was wondering how I would update. Is there any special process? Can I just use the normal OTA update service built-in? Will doing that lose my root and unlock? If possible, I'd prefer the most risk-free method, as I don't want to mess up my Nexus.

Why does every android device have 15-step volume control? Why doesn't it have a smooth slider like Windows or ios? Surely it can't be hardware limitation? Because I've had cheap phones and expensive tablets, and they're all the same.
