Question

Android beginner, Can anybody guide me on this ?

I do have the distance, angle and origin.

newx = (distance * cosθ) + origin.x;
newy = (distance * sinθ) + origin.y;

Instead of this is there any default API which I can depend on in Android

Answer 1

Your question isn’t clear: Are you not understanding Android or the expressions for polar coordinates?

The latter is easy:

/**
 * Factory for PointF 
 * @param origin of the coordinate system (not needed)
 * @param distance this really means "radius"
 * @param angle from the x-axis in radians; positive increases in the counterclockwise direction 
 */
public static PointF getPoint(PointF origin, float distance, float angle)
{
    PointF newPoint = new PointF();
    newPoint.x = origin.x + distance*Math.cos(angle);
    newPoint.y = origin.y + distance*Math.sin(angle);
    return newPoint;
}
