How to enable “Transition Animation Scale” in “Developer Options” programmatically ?

Question

I have some animation transitions for my activities. So when an activity starts, it comes up with some fade animations. Here is the code:

Intent intent = new Intent(this, NextActivity.class);
startActivity(intent);
overridePendingTransition (android.R.anim.fade_in, android.R.anim.fade_out);

The Problem is that, these animations will not run when "Transition Animation Scale" in "Developer Options" is off. So I'm searching for a way to enable this feature programmatically to ensure that my animations shown. Is There a way to set "Transition Animation Scale" to "Animation scale 1x"?

Answer 1

After a few days searching I have found the code which can enable (or disable) "Transition Animation Scale".

        Settings.Global.putInt(getContentResolver(), Global.TRANSITION_ANIMATION_SCALE, 1);

But there is a big problem with this code And if you ask whats the problem? I would tell this line of code needs this permission:

<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS"/>

which is only granted to the system Apps. So your app must be a system app.

UPDATE

and as @TripeHound said, we can

Display a dialog telling the user that the app will look much nicer if they turn this option on (with an option to not display the message again if they really want it off)
