Android :: How To Lock Phone By Application
Feb 3, 2009
I'm trying to lock the phone through my application .I'm using following code PowerManager pm = (PowerManager)context.getSystemService(Context.POWER_SERVICE); pm.goToSleep(160000); I've added following permission to AndroiManifest.xml file <uses-permission android:name=" android. permission.DEVICE_POWER"/> But the application crashes by throwing following exception *E/AndroidRuntime( 436): Caused by: java.lang.SecurityException: Neither user 10032 nor current process has android.permission.DEVICE_POWER.* to avoid the above mentioned exception or tell me some other way to lock the screen

I had a scare today where I left my phone at the gym and thought I had lost it. Whats a good app to locate the phone remotely? (preferably works with GPS AND cell tower location, because I don't have GPS on most of the time.) It would be nice to be able to remotely lock it as well... looks like there are some options available but I'm not sure which one works. The thing with the app store is that you can't sort by reviews, its hard to tell which app is good and which one doesn't work

Is there an app/widget out there that will allow my to instantly manually lock my phone? I know I can change the security settings in Froyo to where it locks when the display is off, meaning I could use the power button on my Droid X, but I don't want it to lock every time the screen dims. In other words I want:
a) phone locks on a timed basis (say, 10, 15, 20 minutes of inactivity)
b) phone locks when I tell it to via app/widget
I tried searching for such an app/widget but most of what I found was just enhancements for the lock screen or replacements that didn't address this problem.

I need to create an Application that can lock the handset at some specific Event. either i want to make use of Require Pattern programatically.
or create a lock application, just like windows mobile in which there are digits to be entered instead of a Pattern.
please guide me to the path if creating this application is possible.

Is there a way to have a phone lock on the Desire, in the way it is used on "normal" phones? What I mean is that I need a phone lock for security reasons - however it is a pain to use it every time I turn the screen on. Is there a way to have it work only when you turn the phone on? Right now if yu don't have a phone/screen lock security set if someone steals your phone they take out the sim card and use the phone normally ... if you do have it, then you must use the password every time you want to use the phone (I hate it). I know the best thing is to have a secured access but I was just wandering if it was possible to do seomething different?

I have use case whereas client wants me to lock an application. Could any of the APIs for the Device Lock screen be re-purposed to lock the application in the same manner? Or would I have to come up with some new code?

I've searched these forums and was un succecfull in finding the answere I needed. So my need is a lock screen replacement application that requires you to type in a password (numerical or letters) doesn't matter. I just hate the swipe to unlock and the tap home to unlock on the Samsung Moment. I don't care about looks so much I just want a functioning app to do what I ask.

We are writing our own application to substitute G1 standard screen lock (where you have to draw a pattern between the dots on the screen). Unfortunately, I have been unable to find documents on how to hook our application in, so that it would be called instead of the standard G1 screen lock. Is there a broadcast sent when the standard lock is activated?

I was wondering if there is any privacy feature for messages. I don't want to lock the whole phone, I just want my phone(HTC Hero Euro) to ask for password or pattern whenever I access messages. Is there any application for that?

Seems to me that Lock 2.0 is the best Screen Lock I've found. Only Issue is, even with the security code enabled, all one has to do is power on/off the phone and your in with no need for the code. What I am looking for is a locking app that doesn't get disabled when powering the phone off/on. Looking for something secure much like every BB has where no matter what you do, to proceed into the phone you need to type in the Lock Code.

Camera application process dies and restarts again when device is Locked/End Call Key is clicked. Steps to reproduce: 1) Launch Camera application. 2) Click on End Call key(it acts as lock screen when there is no active call) or wait till device is locked. 3) Camera application is paused and surfaceDestroyed callback is not being called. 4) Camera process has died and restarted again. I would like to know why Camera process has died after onPause is being called and restarted again when device is put to Lock state. For all key events like BackKey,HomeKey and Accept Key it is working fine.

Is it possible to create a lockscreen replacement at the application level that replaces the device's security lock, whether it be PIN, passphrase, pattern or face unlock, or potentially a new method? I know it's possible in the framework level, and have done it before, but I'm just wondering if it's possible to do it at the application level.
So far the few lockscreen replacements that I've tried only implement a slide gesture unlock lockscreen UI, and falls back to the device's security lock after that.

Is there a way to override the auto lock with a manual one? I'm not sure my kids could make an emergency call if they needed to, it's such a chore to make a call.

I am looking for an application that will allow me to lock out certain applications and features. For example, its common that someone wants to tinker with my phone because they have never seen it. I don't want the messing around in my messaging center, gmail, etc. But the general phone lock is not enough. I want to specify certain apps and functions that will require password or gesture. I found "ES Security manager - application protector" in the market. It worked okay for a day, now its buggy. When I go to a locked app and put in my password. Now it goes to the protector settings instead of the application. Also, it can easily be killed from a task manager app. I need a good solid app that will do this for me.

I did some searching and couldn't find an app like this, figured I'd try here. Anyone know of a app that will disable your wifi when you lock your phone, and enable it when it's unlocked?
