As Edward Falk say, best way is to use path.op() becouse Region is square. And one point can be in 2 or 3 Regions. For example: enter image description here All regions will contain blue point, but on fact only path4 contains this point.

int x, y;
Path tempPath = new Path(); // Create temp Path
tempPath.moveTo(x,y); // Move cursor to point
RectF rectangle = new RectF(x-1, y-1, x+1, y+1); // create rectangle with size 2xp
tempPath.addRect(rectangle, Path.Direction.CW); // add rect to temp path
tempPath.op(pathToDetect, Path.Op.DIFFERENCE); // get difference with our PathToCheck
if (tempPath.isEmpty()) // if out path cover temp path we get empty path in result
{ 
    Log.d(TAG, "Path contains this point");
    return true;
}
else
{
    Log.d(TAG, "Path don't contains this point");
    return false;
}
