I have a tablet and also I have some test cases want to do.
By triggering screen rotation, I know setRequestedOrientation is a workable api.
However, will it be possible to do it in background service?
Say, can I run the service and look at my home screen to rotate every 1 second?
Thanks for the reply.

Is it possible to programmatically take a screenshot of a mobile screen that is currently displaying? I want my app to take a screenshot of another screen after some time from a background service. what I have done already is I am getting the screenshot from the service but it is taking the screenshot of my app activity in which code is written but I want to take a screenshot every 5 mint no matter what screen is on appearing on the mobile from the background screen.
it is possible then help me out, please?
Maybe you can create only a receiver ACTION_TIME_TICK. If you declare it in AndroidManifest, this works when app closed also. However this works every minute and you have to control modulus 5 in onReceive and capture screenshot.
I am creating a standard Android TV app which plays some videos and ran into an issue where screen saver turns on while I'm watching a video.
How can I prevent that from happening? Is there any trigger which I can trigger when I want for a screen to be ON all the time and prevent screen saver from appearing?
This looks like a good solution but screen saver still appears:
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); works on any device when it is set at the beginning of your activity. Where is that code being set? Is it in your main activity or also in your video playback activity?
You can take a look at the Keeping the Device Awake guide for more information.
If you are using a SurfaceView to display your video, you should call .setKeepScreenOn(true); method of the SurfaceView instance.
I have a requirement in android application where i want to turn off screen when no motion has been detected(Motion detection is done using camera).
But the camera should be running in background and taking pictures while the screen is off and as soon as the motion is detected then the screen should be turned on.
How can i do that in android?
I have searched a lot and implemented few things but could not achieve the desired result.
Please help me out.
I don't think this is possible. To take a picture the Camera class needs the SurfaceHolder and it needs to draw the frame on the screen for the capture to work.
I want to know that Is It possible in Android to set an Image as screenSaver.. I am not sure about the feasibily of screen saver...That is when the phone is Idle, then Instead of showing the black blank screen, my application check the Idle time using OnUserInteraction() method and set an Image as screen saver...?? Please let me know If anybody know about this..
onUserInteraction() is deprecated for a start, and it only listens for events on your Activity.
Secondly, having such a screensaver would require that you use WakeLocks, which consume extra battery. And for a screensaver type app, the battery usage would be extremely high.
You might want to look into Daydreams now, assuming you're fine with Android 4.2 and above only.
I made a android project, now my project has a need to set up a alarm type, like blinking screen for which user can see that screen is blinking,
Flashing screen means, screen back light is turn off/on regularly.
Like we make a thread and after every 500 milliseconds we toggle the screen light.
How i do this...
To modify screen brightness, take a look at this question
For repeating schedulded events you can make use of the standard java Timer/TimerTask or simply play with android Handler.postDelayed(Runnable,delay)
For a short introduction to the later, see this question.
Happy coding!
