Android : Implementing Custom Way To Lock/unlock Phone
Sep 9, 2010
Is it possible to implement a custom way to lock/unlock an android mobile phone?I know that in versions 2.1 from android and before, there was only the locking pattern available, and that in version 2.2 it is now possible to set a password as well, but what if i want to make a custom way of locking/unlocking it myself (such as recognizing handwriting, or making some different alternative method for the locking and unlocking process)?Is it possible to achieve this through an application? or would it be necessary to make a version of the Android OS based in the same source code but with changes within it?If it would be necessary to make a different custom version of Android, can anyone give me any hints or tips as to how and where in the source code files are the blocking options considered?

I have seen examples implementing a custom Filter. The Android developer docs talk about implementing a Filterable interface. Does anyone have any advice and/or sample code on the best way to implement filtering in a ListView ?

When I bought the incredible, the Verizon sales rep told me I could use my gmail password to lock/unlock the phone. I haven't been able to find this option anywhere, though. Is it possible to do that?

While taking apart my Galaxy I broke the copper ribbon to the lock button and now I cannot unlock the phone! Is there a hack or other way to unlock this phone? It currently has Galaxo 1.6.3.3
I can probably boot into recovery and flash any zip but currently I cannot get to the home screen as it is locked so Lock 2.0 or other Market app is not a solution.

I would like to know which method you need to use to access the unlock screen and replace it (something like SlideUnlock or Widget Locker). I want to design an app which could work on any phone even those without a custom ROM. This app would then be overriding the default Lock Screen.
You probably need to create a service but I can't seem to find a source code or a good tutorial on it.

We are writing an app to substitute screen/pattern lock on G1. Unfortunately, it is impossible to substitute the original screen lock app with a 3rd party one. The only option left is if we can UNLOCK the phone from a service running in the background when G1 is locked. Is it possible? Is there interface to Pattern/Screen lock? What is KeyguardManager for?

How many of you guys actually use the pattern lock or password before you can use the phone. I have been debating whether or not its a waste of my time b/c even if I get my phone stolen I'm not getting it back. My friends that use my phone can't go through my personal stuff b/c I have a file locker. Even if I did have the pattern lock did anybody create a way to hack it and unlock it like they did with the iPhone?

I found this app that do what I need, however I wonder if there are any free apps that do this? I'm tired of the phone constantly changing orientation when I use it while walking around.

I making an Alarm App.
In my Alarm App, if user set the alarm, the alarm Dialog will be shown at the set alarm time.
but if device(phone) was in lock and screen off, I can't see the alarm dialog.
I need to write code to the alarm dialog will be shown automatically although the device(phone) is screen off(and locked).
I see the source code about AlarmClock in Donut SDK.
It is use the code like below: getWindow().addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
but the FLAG_TURN_SCREEN_ON is only available in SDK 2.0 or later.
I just only use Donut(SDK 1.6).
How can i Screen on & unlock in Donut(SDK 1.6)?

Methods "lock" and "unlock" (and a few others) in the android.hardware.Camera class are missing in the Linux version of the android.jar file for SDK 1.6. Eclipse complained that they were missing, and I checked by opening the jar file and found them missing. I have found them in SDK 2.0.1 though.
To anyone who is developing on similar platform (Linux, SDK 1.6), would you check your jar file and let me know whether yours contains the "lock" and "unlock" methods?

Is there an app that allows you to temporarily unlock your pattern then lock it back without going through settings? Because its gets real annoying to keep putting in my pattern when I'm home alone..

Does anyone have problems with the lock/unlock button? Mine is hard to press (no click or travel) and sometimes it won't recognize that you've pressed it.

Noticed today that when the phone is unlocked with the power/unlock button, that the screen starts off at a significantly lower brightness, but the light sensor seems to then kick in and the correct brightness is then displayed after. This happens for only a fraction of a second, but is quite jerky and immediate.Is this normal, or should the screen brightness remain one constant level from unlock? Of course, changing when it should based on lighting conditions.The same also happens when the screen is about to sleep. Once the lock button is pushed, the screen brightness almost notches down in 2 steps. First at half the brightness, or so, and then off completely. Again, not necessarily smooth, but quite jarring.Again, is this normal of other Captivates?

I am trying to unlock my phone so I can turn off the stream I am listening to in the app StreamFurious Pro but I can not. When I tap the red button right of the track ball, the lock screen comes up, but then when I swipe down it only slides part of the way and then starts to shimmy or bounce up and down. I can see the browser window I last had open below it, but I cant get to anything because the lock won't slide all the way down. Even when that grey bar does get all the way gone, it bounces back a second later.
The menu button does not respond. If I hit the red button again to send it to sleep, it does. Letting it sit does not help. When I hit the red button again, it either shows the grey bar you grab still bouncing, or the lock screen again, but the same thing then happens. I have had streamFurious Pro for awhile and never had this issue. I have not added any new apps since yesterday AM and used my phone just fine between then and now.

Im a bit sick of having to use the powerbutton (on the top of my desire) everytime I have to either lock og unlock the screen. Is there a setting or an app that will let me lock and unlock the screen solely by using the touchscreen?

After some 10 days with my Desire, I am close to getting it 'just right'...
However, I would like to configure the phone to use only the hardware button and the lock pattern in order to use the phone, and bypass the 'slide down' process.
I have tried various permutations and addons but to no avail ...
So to recap:
1 - press upper hardware button
2 - enter lock pattern

The lock screen on my D2 will not unlock. It just began doing this out of nowhere. Obviously, I can't even use my phone.

Anyone notice that the unlock/ lock button on top of the phone seems to go deeper in? meaning its not as tight/ it works still but doesn't seem the same as when i got it first? im afraid that it will stop working at one point. i am past the 30 day and would have to get a certified like new. i called tech support and they said they have no replacement phones in their warehouse currently and i would have to call back maybe tomorrow.

A few of the times that I have played a video using Video Player, I get a lock icon in the top righthand corner. At that point, the buttons do not work. Touching the screen does nothing. I have no idea how to unlock. Each time I've run into this (3 times now), I had to shut down the phone. I must be slow...anyone know how to unlock the video player?

On my blackberry and all previous phones, I was able to customize a text banner, and I'm not finding a way to do it on my Motorola Droid. I usually put my email address on the lock/unlock screen so that if some honest person was to find my phone, they could email me to let me know they found it. Otherwise, it would just be lost. I know that there are theme apps that I can install, and I'm not sure if they have that capability, but if anything, I'd prefer not to have to download any apps to do this. I've also thought about creating a wallpaper that has that information in it, and setting that as my wallpaper. It seems like too much work.
