Question

If the application has android.permission.WRITE_SETTINGS permission to change settings, there are ways to change the system font size programmatically, as described in How to programmatically change device font settings: font style and font size? . However, I could not find a way to resize the display programmatically. Is it possible?

What have i tried?

I checked the options in the Settings.System list of convenience functions needed to change the settings programmatically.

Update :

I opened a function request for the same: https://code.google.com/p/android/issues/detail?id=214124 . If you feel this would be helpful, please run it.

Thanks for your help in advance!
