Closed 8 years ago.
Well I searched quit a lot on the new, and I found no good answer for that, unless your phone is rooted.
I am pretty sure you can do this in bash codes, but I have no idea where even to read about that.
I want to make an app with 2 buttons.
1st button will change the date of my phone 1 day forword
2nd button will change the hour of my phone 1 hour backword.
I want that the button will change the clock in the settings of phone

Impossible for non-system apps that don't have a special permission.

I am making an application and I want to make app in such a way that user directly open that by using volume key, suppose user click twice the volume+ or volume- buttom and the app will directly open without home screen or without any interuption.
I want to add this functionality using the code in Android Studio. If anyone know how to add this, please help...
What you are asking for is not App/Code nor Android Studio related but device related, If the Original Equipment Manufacturer will allow a device to have a shortcut button it could be possible to achieve that on those devices.

It depends on your device, but generally you can just press the Volume Down and Power buttons at the same time, hold them for a second, and your phone will take a screenshot.
It Depends on how you want to take screenshot
if you want to take screenshot from eclipse then..
Goto DDMS->Devices->Select your Device-> click on Camera(Screen Capture) icon on Right side -> save.

How to prevent an android activity to get killed
(3 answers)
Closed 9 years ago.
I'm trying to create an app that sets an alarm if the screen is off for too long. This will be checked in the background every 5 minutes. Unfortunately android kills my app sometimes and I need to keep my app active in the background. What is the best way to do this?
I was also thinking about restarting every 5 minutes if the app is killed. Is this a better way to keep my app mostly active in the background? How to do this? Or is there a better solution for me?
Maybe restarting the way like Facebook does?
I would recommend having a look at Mark Murphy's WakefulIntentService.
I think i fixed it by using a simple service that does nothing except for an infiit loop of logging.

You can check android-screenshot-library, which should work without a root access; however it still have some limitations
Also AndroSS is another option for Tegra-based Android phones
