Android :: Enable / Disable PatternLock Screen From Code
Feb 3, 2010
I try to find a way to disable the PatternLock screen temporary. I don't want the lock to be disabled completely, but the user should not need to re-enter his pattern all the time.
My idea is to write a service which disables the pattern after some user activity and re-enables it after a while. (and even more)
There are apps on the market that do something like that (i.e. AutoLock or TogglePattern), so there must be a solution ;)
I know that I can prevent a lock completely by using:
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON)
or
KeyguardLock.disableKeyguard()
But that is not what I'm after.
I saw the class "com.android.internal.widget.LockPatternUtils" in the android sources which is used by the settings activity, but this class is not (at least as far as I know) accessible for a "normal" application.
Do you have an advice?

I need to find a way to enable / disable mobile data (the thing you can manually enable / disable in Settings->Wireless->Mobile Network (android 2.1)But I can't find any API for that.For WIFI, there's a method setWifiEnabled(boolean) on the class WifiManager. But I can't find anything like that for the data network... no method for this on TelephonyManager or ConnectivityManager.Isn't it possible to programmatically enable / disable mobile data?

According to the emulator docs, you should be able to enable/disable networking with the F8 key. I doesn't work for me and I'm trying to determine why.
I'm developing on OSX Leopard. I've also tried in a virtual Windows instance (Windows 2008 server running in Parallels). No luck in either case.
I've tried the obvious stuff like fn + F8, etc.
Should there be any sort of visual cue that networking has gone online or offline when F8 is pressed?

How do I enable/disable GPS and Wifi providers? I check to see if they are enabled by using this code:
locationManager.isProviderEnabled("gps") locationManager.isProviderEnabled("network")
If both are false, I'd like to turn enable the GPS provider and/or the Network provider so that the above checks would return true. Is this possible? If so, what permissions does it require?

I want, and I have for a while been willing to, disable and enable DATA (2g, 3g, whatever) with a long press of the search button. And I mean only long-pressing it, NOT opening an app with it and disable it from the app (doesn't make any sense, otherwise one would press the HOME button and disable it from a widget there).

Is there a way to enable or disable tethering (USB or wifi) on an android phone programmatically? Perhaps an API in android SDK or NDK or any even non-UI command to do that.

I want to control the system settings "auto brightness", setting it ON or OFF.I'm able to control the brightness level but only if AUTO is OFF. From what I read until now there is a SCREEN_BRIGHTNESS_MODE in Settings.System but only for API level 8 or higher and also not recommended to mess wit it. But currently my phone has Android 2.1 (API 7) and there are widgets that can control this setting (enable/disable auto brightness and set the level). How is this done?

I am writing an widget application for android.
I have a requirement where i need to disable the widget on some intent, i.e., I have the remove the widget from the android home screen and remove from menu options so that the user cannot add the widget further.
I have to enable the widget on some intent, so that, the framework automatically adds the widget to the home screen, by calculating the empty position available on the home screen, and the many option re-appears in order to add the widget further.
Please let me know if this can be possible..

The service providers in my country are charging for the MBs I downloaded in my GPRS/EDGE connection. So, whenever I want to disable the GPRS, I just change my default APN to something wrong and then correct it when I want to enable it again. I couldn't find another way to enable/disable. I think,Android team assumed that only 3G users with a good data plan only would use this phone. Anyway, I just want to develop an application which can do that automatically for me. However; I couldn't find how to change the APN settings in the docs. but I couldn't find how to use it. Could you please help me? Any alternative ways and/or suggestions are welcome.

I want to develop an application that disable the Background Data (new feature in Android 1.5) and Auto Sync and then enable GPRS/EDGE connection and vice versa.
I figured out how to enable/disable GPRS/EDGE by changing the APN settings. (weird solution. However; Android developers couldn't think a user may want to disable GPRS/EDGE) But, I couldn't find a way to enable/disable Auto Sync and Background data.
I investigated the Android code and as I understood, the Sync operation is an intend. So, I wanted to reach with putExtra to the intend and trigger the enabling/disabling. But; I couldn't find the correct keyword.

Is it possible to programmatically disable and enable the led indicator light on an Android device? I am not referring to just turning it on and off as in a notification. I did not see anything in the api that would do so. I am guessing this is hardware specific if it is possible at all.

Is there a general guideline for application developers about when to disable haptic responses? I know there are ways to enable/disable long-press haptics, but if an application was created to use haptic feedback for other events are there guidelines that application developers should follow? For example, if the user was to go into Settings->Sound & display -> Haptic and set that to OFF, should all applications refer to this setting as a rule of thumb?
From and end user point of view, I would like to have global control of haptic feedback especially if I find it to be annoying. I have seen several postings in the android forums looking for a "global override" to haptic responses. Ultimately, I think it is a question of should each application provide a menu to enable/disable haptic support, or should this be more of a global Setting for the device.
I personally feel applications should refer to the global setting, but would like to get feedback from other developers about this. Reference postings I was referring to: http://www.droidforums.net/forum/droid-general-discussions/6812-hapti... http://androidforums.com/samsung-moment/13633-how-do-you-disable-vibr.

In my application has a ListView. When long press on item the "Context Menu" will appear. I want to check the data ID, then set disable/enable to my Context Menu "Items". I can not find out the function like getMenuInfo() or something like this.
@Override
public void onCreateContextMenu(ContextMenu menu , View v, ContextMenuInfo menuInfo)
{ super.onCreateContextMenu(menu, v, menuInfo);
menu.add(0, ADD_FAVORITE_ID, 0, "Check");
menu.add(0, ADD_FAVORITE_ID, 0, "UnCheck").setEnabled(false);}

I have an Android device where the default is for the Notification bar to be off so you cannot drag it down. I want to write a simple program that turns the notification bar back on so you can drag it down to view the notifications. If someone could show me the code to do that.

For those of you looking to either Enable JIT or Disable JIT on a ROM that has JIT built in (or you've manually flashed it) and decided you wanted to remove it. I had a little trouble searching so I figured I'd post it with a simple logical subject line for future searching.
In the /System Directory you need to fine the file called:
build.prop
then edit the line:
dalvik.vm.execution-mode=int:jit
to say:
dalvik.vm.execution-mode=int:fast
and revsere it to enable it back (fast to jit)
You can do this a few ways.
1. Use a file explorer on your phone (such as ES File Explorer) or Root Explorer find the direcotry /system make sure the drive is R/W (read/write). Open the file, build.prop, then scroll down to the bottom of the file and it should be within the bottom 5 lines and do as stated above.
2. Use adb commands, connect phone via USB.
adb remount
abd pull /system/build.prop build.prop
On your PC find this in your c:"androidsdkdirecotryhere"
ools and edit with your favorite text editor.
then save the file, and go back to your cmd window and type
adb remount
abd pull /system/build.prop build.prop

I got my Incredible almost two weeks ago and haven't modified it in any way other than switching to LauncherPro instead of Sense. I've seen these buttons (highlighted in red in the screenshots) in various places; Used for selection of a single item or as "enabled" or "disabled", they just don't look right. Especially in Astrid, they don't look like they do in the screenshots from the market. what are these buttons called (they're not radio buttons or checkboxes, so I'm assuming they have a name)? Does this happen to anyone else?

Is it possible to enable/disable action bar icons? The scenario is that on the action bar there are two search icons, but they do different jobs, one searches the contents of the app while the other filters the listview (searches the table of contents only).
So if a user only wanted to use only one search method, is it possible to make an option in the settings on the app to enable/disable action bar icons?

I enabled APN in the settings. But, I want to be able to enable/disable my APN so I can be sure that I'm not getting charged for using the Internet when I'm not. On the top of my screen I see an E with 2 arrows, one pointing up and one pointing down, when I turn my WiFi on this disappears and is replaced by a WiFi icon, and I don't get charged for browsing. But I want to be able to turn APN on and off, I can't uncheck the option for APN which I chose, and the application I downloaded does not work. The icon remains there when I'm not connected to a router even if APN is disabled.

As Nexus One is the only model which has already "partly" updated to Froyo,Before Froyo, if I wanna enable/disable mobile data usage, I used a passive way, changing the APN server setting, to fool the system so it couldn't connect.In Froyo, there is a new option under Setings -> Wireless & Network Settings -> Mobile Networks called Data enabled/disabled, which is a much direct approach than changing the APN.But up to today, I've yet to see a widget which targets at this option. Currently I hv made a 3G shortcut to that setting page on to my home screen. Really hope there will be a toggle widget instead!So how do u guys enable/disable data usage at the moment without a handy widget on Froyo?
