java - Android: Change canvas clipBounds -

-

i trying to draw custom slider has tooltip fades in , out on touch events. having trouble canvas clip bounds. tooltip placed above slider, giving negative canvas coordinates, should fine since replace clip bounds on every ondraw.

when running on lenovo tablet works expected, on google nexus 7 odd happens. clip bound acknowledged first ondraw (i have tried filling canvas solid color see size) , after that, though debugging says clipbounds correct, outside original clipbounds clipped.

does know causing behaviour?
