I want users to be able to control the birghtness with a slider. Please answer in the simplest way because im a noob when it comes to android.
My phone is opening in my jacket pocket. Anyone else have this problem? I can hold the back and give the phone a MILD shake and the slider completely opens. Also if I push on the Magnifying Glass while the phone is closed, the phone has quite a bit of downward travel, but the other three corners dont...this happening to anyone else?

So that to unlock the phone I press the slider open, then when I close the slider the phone turns the screen off and locks.
How to write the app? It needs no UI, no anything.When slider goes from open to close, screen off. By slider i mean the slide out keyboard.
We want to create a screen which should have different list views and the user can slide (Left or right) to view another list view (just like in TweetDeck and in home screen on some Android OS version). There is also a list of dots which identify how many list views are there.

View 5 Replies View RelatedI'm wondering how I can choose to wake up my phone without having to do the slider everytime or at all.I work at my home office 12 hours a day and my phone is on my desk always.I use it alot and put it down, then use it some more and back down again.I'd like to conserve battery and not set it to just "screen stay" aka never timeout because that just uses so much battery with the screen on.And using that slider over and over and over well you get the point.So how can I just set it to wake up on like touching the screen or something?
View 7 Replies View RelatedThese are mostly minor things, but it's only been a month. To be honest, I think the BodyGlove that I had on the phone for the first couple of months slightly distorted parts of the phone.
Why do I say that?
One, I have another thread about this, but the plastic edge that runs around the keyboard portion of the slider (it's like a rubber bumper, it runs over the USB port and around the rest of the phone) is a bit loose where the USB port is. Also, the screen seems a bit loose when the slider is closer. I can move the screen slightly side to side (don't know how to describe it), as if it's not quite locked into place.
I don't remember these being issues when I first got the phone, but I attached the BodyGlove about 2 hours after I got it so I really have no idea. But the slider fits together so tightly that I think the clasps that held the BodyGlove on the phone may have causes the phone to adjust slightly and now that I'm not using the BodyGlove any more that adjustment is causing looseness.
Device: MTK6575 Tablet with Analog FM
OS: Android 4.0.4
Condition: USB Debugging enable
Currently my Tablet behave strangely where when I switched it ON, it did run as per normal. But when I slide the unlock slider, the Tablet switch off.
I did a backup user data. Try entering recovery, wipe data/reset factory. Reboot the Tablet, it also did run as per normal. But when I slide the unlock slider, the Tablet switch off.
Then I try another approach. Try entering recovery, wipe data/reset factory. Connect the USB cable to computer. Reboot the Tablet, it also did run as per normal with no unlock slider where it did show a USB enable menu. Press back and it did run as normal. Then I disable the "slide the unlock slider" in setting. Everything work as per normal. Try restart and no problem.
Then I restore previous user data, unfortunately I cannot disable the unlock slider. Try Connect the USB cable to computer, the slider still there.
I'm looking for a way of disabling the unlock slider via ADB command.
Another way I can think of is sideload "Screen lock suppressor" apk into system.[URL]...
Now I forget how to push the apk into system. Or, any other apk to disable the unlock slider.
I'd like to set the sound slider on the lock screen of my Droid to make my phone set to vibrate instead of fully silent. Is there a way to do this?

View 5 Replies View RelatedIs there any way to control from outside an Android which screen has become nuts ?
I have a chinesse phone ( and MTK 6573) which touch screen has become nuts (most of it has become unresponsive and often a continuos touch imput is detected in the center-left side of the screen). So, it has become useless...
The thing is, I would like to access to it, in any way, to recover some of the data I have on it. Also, becouse I try to disasemble, volumen key seem not working. How could I connect to it ?
I tought of the mimobiler, but I need to enable it trought touch and hadn't been able I tought backing up and restoring in another mobile (an MTK6577), but volumen key not working for ColckWorkRecovery would be to control it from mouse or similar, in a way that does not affect the missfuncionality of the touch screen (should be disable I presume). But anything that allows me to recover the saved phones (several got stored in mobile instead of google account), and a couple of apps data (a fianace data and a notes app) would be great something like remote-titanium-backup ?
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).

I want to control the brightness of screen using a background service in android.
Existing Solutions:- There are similar question posted in the form in below link:-
http://stackoverflow.com/questions/1791340/adding-screen-brightness-controls-to-android-application
Why existing solution will not work? All the solution provided in the link works well with an Activity, but I want to write a Background Service which controls the brightness of the screen.
However, Android screen cast is a cross-phone program.Android screen cast is a java program that allows you to connect to your Android phone through an USB connection. I think you need ADB and root access for this.
I am searching for something like this that also supports German charakters like umlaute.
I was toying around with different ways of turning the screen on and off and of course Wakelocks show up quite alot in this discussion. From what I gather, I can acquire a wakelock (partial or full) to turn the screen on and keep it on for the whole duration my app (or service) is running, and then release it to turn the screen off. My question is on the huge issue of battery consumption surrounding wakelocks. As long as I make sure to to acquire it just to keep the screen on and release it to turn the screen off (or when the screen turns off), battery consumption should be minimal right? The wakelock's only there when the screen is on so it will definitely let the phone go into deep sleep when the screen's off but does the wakelock actually consume battery itself while it's acquired? Or is all the fuss just bad programming (leaving the wakelock on when the screen turns off, etc.)?
View 1 Replies View RelatedHow do you control the screen being on or off during a call? My screen blanks, I guess to keep you from hitting buttons with your ear, but when using a bluetooth headset it also blanks. Sometimes tilting the phone wakes the display, sometime the top button does. But sometimes neither hs an effect, and the screen remains off until the call is over. Anyone else have this, and figure it out? Are there settings somewhere to control this behavior?

Anyone tried this yet? Not quite there on features yet, but regular updates and I can see this being a big player. Loving the skins and animations. Zoom wheel is pretty cool too or you can use a slider if you prefer. Was playing around with some of the new skin packs - one of them is kind of scary!

View 2 Replies View RelatedI rooted my phone (HTC Hero 200 running 2.1) a few days ago, went with Fresh 2.1, but after having some trouble with WiFi Tethering I opted for Damage Control. I did a lot of searching online and found Damage Control 0.999999% and installed it on my phone. It is working okay for the most part, but I found out that there are a number of 2.0 versions out there so I decided I wanted to update to a new version.
1) Version 2.09.1 would not load (and I read that it was unstable so I removed it and rolled back.
2) I went with version 2.08.1 and when I rebooted the phone it would get stuck on the boot-up screen and would not go any further (I went in, wiped the phone, went back to the initial Kernel I installed (2.6.29-8f4e5478 htc-kernel@and18-2 #1), but it still wouldn't work.
3) I research other Damage Control ROMS and went with 2.06.1 Lite to download the DCUpdater, thinking that if I went with this edition I would use it to get to 2.08.1, but same result as before.
Do I need to download a new Kernel? Do I need to start from scratch and root my phone all over again?
Some Android programs trigger the "media volume" slider when the hardware volume up/down buttons are pressed. My application seems to set the ringer volume when the hardware buttons are pressed. How would I enable the media volume slider? I would hate for users to have to go into their settings to change the media volume when they use my application.
