Make ObjectAnimator animation duration independent of global animator duration scale setting in developer options

Question

How can you make ObjectAnimator independent of the "Animator duration scale" developer options setting when constant and unmodifiable speed is critical?

Answer 1

If you dont want to mess with setDurationScale, just do this

//in activity, kotlin
val animScale = Settings.Global.getFloat(this.contentResolver, Settings.Global.ANIMATOR_DURATION_SCALE, 1f)
animator.setDuration((timeInMs/animScale).toLong())

Answer 2

I noticed there is no explicit answer for this. You can do this by calling the hidden API via reflection:

// Get duration scale from the global settings.
float durationScale = Settings.Global.getFloat(context.getContentResolver(),
                        Settings.Global.ANIMATOR_DURATION_SCALE, 0);

// If global duration scale is not 1 (default), try to override it
// for the current application.
if (durationScale != 1) {
  try {
    ValueAnimator.class.getMethod("setDurationScale", float.class).invoke(null, 1f);
    durationScale = 1f;
  } catch (Throwable t) {
    // It means something bad happened, and animations are still
    // altered by the global settings. You should warn the user and
    // exit application.
  }
}
