Sorry it's an error in the javadoc, below you can find an example on how to read the ink path:

if(annot != null && annot.GetType() == 15) {
			Path inkPath = annot.GetInkPath();
			float pt1[] = new float[2];
			float pt2[] = new float[2];
			int index = 0;
			int cnt = inkPath.GetNodeCount();
			while( index < cnt ) {
				int op = inkPath.GetNode(index, pt1);
				switch( op ) {
					case 1: //line to
						Log.i("---INK---", "-- line to " + pt1[0] + ", " + pt1[1]);
						index++;
						break;
					case 2: //curve to
						inkPath.GetNode(index + 1, pt2);
                                                float pt3[] = new float[2];
						inkPath.GetNode(index + 2, pt3);
						Log.i("---INK---", "-- curve to " + pt1[0] + ", " + pt1[1] + ", " + pt2[0] + ", " + pt2[1] + ", " + pt3[0] + ", " + pt3[1]);
						index += 3;
						break;
					default: //move to
						Log.i("---INK---", "-- move to " + pt1[0] + ", " + pt1[1]);
						index++;
						break;
				}
			}
			inkPath.Destroy();
		}
