created issue #1

Jun 24, 2016 05:35AM

Background:

Android N comes with a feature to change system "Display Size" from Accessibility Settings, in addition to the previously present feature of changing "Font Size".
If an app has "android.permission.WRITE_SETTINGS" permission to change the settings programatically, one can modify the system font size programatically like:

float scale = (float) 2.0;
Settings.System.putFloat(context.getContentResolver(), Settings.System.FONT_SCALE, scale);

Request:

In same way, can there be another convenience function in

https://developer.android.com/reference/android/provider/Settings.System.html, which possibly could be used like below to change the display size for Android N and above?

Settings.System.putFloat(context.getContentResolver(), Settings.System.DISPLAY_SIZE_SCALE, scale);

1. Code Sample attached. Cannot attach the original app code because of copyright.

2. Steps to reproduce it:
1. Tap on the first image (this activity is portrait)
2. It will go to a landscape ativity
3. Tap back button
4. Observe that the previous activity goes to portrait, then to landscape and finally portrait again.
Note: On the original app is happening always. On this code sample I was able to reproduce it 5/10 times.
