If I swipe from Right to Left in Samsung S5 or any device lower then 8.0 I get XVelocity in positive numbers and when I swipe right to left in devices greater then 8.0 like android 9 (Note9, s10) for the same swipe I get XVelocity in negative numbers. why it is so ?

mVelocityTracker = VelocityTracker.obtain();     
mVelocityTracker.addMovement(event);
mVelocityTracker.getXVelocity()

just convert to absolute numbers. – Martin Zeitler Jul 22 '19 at 13:33
@MartinZeitler can you please explain a little bit? – Obaid Jatoi Jul 23 '19 at 05:55

there's nothing to explain; it's a primitive math function. absolute means not relative to zero. – Martin Zeitler Jul 23 '19 at 06:36
