Class android.graphics.PointF

Removed Constructors
android.graphics(int, int) Set the point's X and Y coordinates by automatically promoting (x,y) to float values.
 

Removed Methods
void add(PointF) Add v's coordinates to the point's
float crossProduct(PointF, PointF) Returns the cross product of a and b, treating them as 2D vectors
PointF difference(PointF, PointF) Returns a new point whose coordinates are the difference between a's and b's (a - b)
float distance(PointF, PointF) Returns the euclidian distance between a and b
float dotProduct(PointF, PointF) Returns the dot product of a and b, treating them as 2D vectors
boolean normalize() Set the point (vector) to be unit-length in the same direction as it currently is, and return its old length.
void rotateCCW() Rotate the point counter-clockwise by 90 degrees, writing the answer back into the point.
void rotateCW() Rotate the point clockwise by 90 degrees, writing the answer back into the point.
void scale(float) Scale the point's coordinates by scale, writing the answer into dst.
void set(int, int) Set the point's X and Y coordinates by automatically promoting (x,y) to float values.
boolean setLength(float) Scale the point to have the specified length, and return that length.
boolean setLength(float, float, float) Set the point to have the specified length in the same direction as (x,y), and return the old length of (x,y).
boolean setUnit(float, float) Set the point (vector) to be unit-length in the same direction as the x,y params, and return their old length.
void subtract(PointF) Subtract v's coordinates from the point's
PointF sum(PointF, PointF) Returns a new point whose coordinates are the sum of a's and b's (a + b)
 

Added Methods
void offset(float, float)
