(context.getContentResolver(), _BRIGHTNESS, screenBrightnessValue) The simplest way to show a window on another display is to create a Presentation. The key code which is used to change the device screen brightness value is like below. To obtain a WindowManager for a different display, use createDispla圜ontext (Display) to obtain a Context for that display, then use Context.getSystemService (Context.WINDOWSERVICE) to get the WindowManager.

You can read the article How To Grant Write Settings Permission In Android for more information.
Because change screen brightness action needs _SETTINGS permission, so when you click the button for the first time, it will popup Can modify system settings panel to let you change the app permission manually. There are two buttons on the screen, when you click the first button, the screen brightness will be turn off, when you click the second button, the screen brightness will be changed to max value. What we need to do is to take action at a higher level where the code that draws the ActionBar - ABS or Android itself - contains no data regarding window size, so that we may adjust it to our liking.If you can not watch the above video, you can see it on the youtube URL If you ever taken a close look at ABS source code or been interested enough to examine the structure of a native ActionBar, you know that any attempt to resize an Activity when calling the setContentView method fails: both the size and location of an ActionBar will remain unchanged. 
The library is integrated into projects as a separate module, along with its sources.
Rendering the background unresponsive to touch or any other user inputĬalculating optimal floating activity sizeĪs mentioned above, we plan to work with phone-version Activities that use the ActionBarSherlock (ABS) library. Making the Activity transparent so most everything behind it is visible. Calculating an optimal Activity size and determining its location. Task implementation takes place in 3 stages: Below illustrates and describes how existing Activities were simply modified in order to meet the new device’s format requirements - with the code reused to the max: Since we already had a phone-optimized version with all Activities written, it would have been a waste of time to start completely from scratch. Ideally, the Activity should be located center-screen and reach full-screen across the shortest display dimension and cover 2/3 of the screen across its longest dimension. .putInt(getContentResolver(),, time) but is deprecated.I also tried Power Manager PowerManager.SCREENDIMWAKELOCK which is also deprecated Any other way around for the same. preserve the original size of the floating activity in both portrait and landscape orientations of the device. 
implement a Floating Activity in android application, i.e., a transparent Activity so that users could input the required information while also being able to see other Activities or the app itself on the screen in the background.We were not only making a tablet version for an application based on the ActionBarSherlock library but we also needed to: However, the task within one of our recent projects was rather unique. Usually developing a tablet version of an existing mobile app that’s been optimized for a smartphone is fast and easy: you can use Fragment, decompose Entities, etc.
