c - Warning: Expression Result Unused in RenderScript -

i don't it. unless i'm missing something, utilize on next line.

blockaverage >> blocksize; //warning:expression result unused homecoming rspackcolorto8888(blockaverage);

you meant:

blockaverage >>= blocksize;

your code doesn't alter blockaverage; compute value of blockaverage shifted right blocksize bits, throw result away.

you must utilize assignment change value of variable (the above is, of course, short blockaverage = blockaverage >> blocksize; i.e. assigns new value blockaverage).
