Android :: Waking Phone & Safely Disabling Keyguard
Feb 23, 2009
Does anyone know how to do this correctly? I can't find any examples & the API documentation is pretty hard to follow.I am guessing I need to use the KeyGuardManager and PowerManager... but can't figure out how to bring my activity up past the keyguard and re-enable the keyguard so my activity doesn't let someone get past the lock when my activity awakens.

I have an activity that I want to show up when the phone goes to sleep. However, the phone wakes up when I press the volume buttons or the camera button.
I tried using the dispatchKeyEvent(KeyEvent event) method, but it doesn't prevent the phone from waking up.
How else can I disable that functionality?

I know, given the multitude of apps and setups that could be causing this, but hopefully someone can help. Sometimes my phone just won't come back up at all. Lock and power buttons do nothing and it needs me to pop the battery to get it back.I don't want to push anyone down this line, but I get the feeling it's related to being in the stock case?Any ideas, it's been happening a couple of times a day for the past few days now?

I'm not sure if this is worth complaining about but is anybody else experiencing their phone waking up on its own while it's connected to the charger? I'm not sure when it started exactly but I'm sure it was after I updated to OTA 2.2.It's not hot or does anything else just that the screen turns on, stays on for like 2 seconds, and than the screen turns off. It seems to occur randomly. Is anybody else having this issue?

With my Storm, I could wake up my phone by pushing on the screen. Does the X do this, or do you need a special app for it? Touching the screen to wake it up is much easier than trying to push the small home button.

Nothing blocking the sensor sometimes I cant end a call because the phone wont wake up! I click everything,slide everything sometimes just sometimes It will wake up if I push the little button up top. Major bummer when leaving a voice message. Anyone else have trouble ending phone calls or the thing going into some deep sleep?

I don't know if this is a common problem with the Behold 2 or not, but my phone isn't automatically reconnecting to wifi after waking up from sleep.I have to manually toggle the wifi switch to off and then back on for it to reconnect.I'm using Warheads Rom with new kernal if that helps at all.

I would gladly pay money (and i'm sure a lot of eris -> incredible users would too) for an app/patch to give me the option to use an alternative key/button (menu/home button, or even vol rocker?) to wake up the phone when it's in sleep mode. It was one of the major reasons why I ended up returning the moto droid for an eris (the eris has a power button on the bottom of the phone). Would root be required for this kind of mod?

I can't be 100% sure which one it is. But I installed Nonsensikal 13.2 about a week ago, love it, and was about to basically settle on this as my default rom until Saturday. Starting Saturday my phone has become non-responsive about 5-6 times. Meanin the lock screen won't come on, and the power button will not turn the phone on or off.I'm assuming this means that the phone is still on when this happens, because if it had just powered down randomly I'd think the power button would turn the phone back on I have to pull the battery out and power it back on to start working again. I don't have setcpu or autokiller running, but I am running juicedefender (in case any of that is helpful for anybody.)

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 working on a lock screen application and am disabling the keyguard using the following code snippet which I call from a service on receiving the ACTION_SCREEN_OFF broadcast: KeyguardManager keyguardManager = KeyguardManager)getSystemService (KEYGUARD_SERVICE); KeyguardLock keyguardLock = keyguardManager.newKeyguardLock (getPackageName()); keyguardLock.disableKeyguard(); This seems to work fine, but when I return to the home screen the notification bar does not respond to touch/drag events. It's stuck and I can't drag it down until I hit the Home button. Has anyone seen this behavior? As far as I know there is no way to disable the dragging of the notification bar programatically. Perhaps something I'm doing is triggering a bug? Any ideas?

How can I disable the keyguard when a broadcast receiver is activated by screen_on, so that when it occurs the user sees an activity that I have started behind it?(The activity is running already)I have been trying the following code from a broadcast receiver triggered by screen off.It doesn't seem to be working though as it is. When I turn the screen on, I still have to manually unlock the keyguard on the phone to reveal the activity behind it.

I have an application in which there will be a service continuously running in background and on certain conditions service should call an activity or pop-up a dialog. I think this is possible. The question is, in case device keyguard gets on say after 2 minutes of idle time then will the service continue running in background. And what will happen when the condition of opening pop-up or Activity is reached.

Is there a app or a way to not have a call come through my cell when listening to Pandora or some other audio app? This happens frequently and it's a pain in the ass to get back to normal after I send the call to voicemail. I'd like to have it where incoming phone calls don't interrupt audio streaming. I have a Samsung Moment.

I needed edit the SystemUI.apk for add a feature, and for this i should add a line in the AndroidManifest.xml, when i did all the modifications and install the rom, i get this message "KeyguardTestActivity has stopped".

I don't know why this don't work! I'm using the last apktool, i have installed the framework-res.apk of the stock rom!

I'm going to be traveling to S Korea and Japan next week. I'd like to use my DInc for wireless data when I have a wireless network available, but I don't want to get hit with any $100 roaming or international use fees. I think what I can do is turn airplane mode on while I'm abroad, and then enable wifi on top of airplane mode whenever I need it.

how I wound up with this but after a factory reset I noticed that in my phone contacts there are all these "connections" with a chainlink type icon. I didn't have these things before my factory reset.
I don't sync with Google, I use Companion Link and DejaOffice. DON'T want to sync with Google. I can't find a way to "un-connect" and get rid of these things. If I press on them, I get an option to add a connection but no option to disconnect that I can see.
I'm assuming this is either an Android or another one of freaking Google's attempts to invade a my space, privacy and run my life and I don't like it.

Everytime I plug my Desire into either of my PCs, I get a warning from Norton 360 saying that it (the Desire) is infected with a virus called VBS.Runauto. Having checked the details of this supposed virus, it appears to be in the Google folder. Has anyone else had this problem, and is there a way to "ignore" it or safely remove it without causing problems?

it's very difficult to wake the screen back up because of all the power saving things that go into effect when you turn the screen "off" using brightness = 0;Let me first point out that I'm not really tied to power constraints in this particular application.One of my assumptions is that this device (Droid) will be plugged in when this application is run. Ideally, I'd like to not hammer the battery if I don't have to, but I'm open to it if it's the only way.So, back to the issue when the display is off, pretty much everything shuts down.For instance, one idea I had was to shake the display back awake by reading the accelerometer.However, as soon as the display goes off, my listener that was reading values from the accelerometer (be it in an activity or a service) stops echoing values.I can't register any key listeners because when the display is off, if I press anything other than the unlock button (e.g. volume up/down, camera button, etc.)
In short, it appears that once the display goes dark, the only way to interact with the user is by hitting the "unlock" button.This isn't ideal because it's awkwardly placed.I had *really* hoped to be able to re-activate the device by pressing anywhere on the touch screen.I can understand that the touch screen is disabled for power reasons, but I was hoping I could override that(given I don't mind the power draw).Failing at that, I'd settle for any of the accessible keys (even the keyboard) reacting to user input and waking the thing up.

I know JT said wait it out, but I havent read about anybody having it in reboot for over an hour.I dont know what to do?

When I connect to my company's Exchange server, it pushes a password policy that makes me have to use a password on the phone. With my Sprint Hero, I used an app called LockPicker to disable this requirement. Apparently this app only works on HTC Sense. Anyone know how to do this with the Fascinate?
