androidgraphicsPath

androidgraphicsPath refers to the Path class in the Android graphics framework, typically used as android.graphics.Path. A Path represents a geometric path described by a sequence of segments and curves, and is drawn with a Canvas via drawPath or used for clipping with clipPath. It is a fundamental tool for rendering custom shapes and complex outlines in Android applications.

A Path is built from segments such as moveTo, lineTo, quadratic and cubic Bezier curves (quadTo, cubicTo), and conic curves (conicTo). It supports absolute and relative variants (moveTo vs rMoveTo, lineTo vs rLineTo, etc.) and can be closed with close to form a closed contour. Additional methods allow appending shapes like addRect, addOval, addCircle, addArc, addRoundRect, and addPath, enabling composition of complex shapes. The path’s fill behavior is controlled by Path.FillType, with options such as WINDING and EVEN_ODD determining how overlapping regions are filled.

Path can be transformed and reused: it supports transformations via Matrix, and can be offset or transformed in place. It can be combined with boolean operations using Path.op to perform union, difference, intersection, xor, and reverse difference with another path. The bounding area of a path can be computed using computeBounds. For animation and precision placement, PathMeasure provides length information and allows sampling positions and tangents along the path.

Rendering and usage: a Path describes geometry that can be drawn on a Canvas with a Painter’s fill or stroke, or used as a clipping region. Reusing Path objects is common for performance, and combining them with other paths enables rich vector-like graphics in Android apps.
