How to check if a bitmap (or canvas) is empty in Android -

i have implement function return me boolean if bitmap or canvas empty in android.

how can ?

i have tried solution, doesn't work:

bitmap emptybitmap = bitmap.createbitmap(mybitmap.getwidth(), mybitmap.getheight(), mybitmap.getconfig()); if (mybitmap.sameas(emptybitmap)) {     // mybitmap empty/blank } 

how check if bitmap empty (blank) on android

another solution have considerated is:

fastest way check if image white or transparent

but can't check every pixels, spend time in operation

sorry it's late apparently best way create bitmap , check if it's same boolean res (bitmap.sameas())
