colors - android studio cannot resolve symbol "ff" -

i trying retrieve value of red, green,blue pixel color value .so need perform shift , multiply operation.but android studio notifying above error @ following code.

clr=bm.getpixel(0,0); cred=(clr & 0*ff)>>16; tv.append((string.valueof(clr))); tv.append((string.valueof(cred))); 

error:cannot resolve symbol ff @ line no 2;

it should 0xff , not 0*ff

cred=(clr & 0xff)>>16; 

0*ff multiplying 0 unknown symbol ff (since don't have variable named ff in scope)

while above code compile , resolve error, not correct code reading red color value bitmap pixel. correct code be

cred = (clr >> 16) & 0xff; 

but easiest , safest way use color class.

int = color.alpha(clr); int r = color.red(clr); int g = color.green(clr); int b = color.blue(clr);
