Usage

From source file:Main.java

private static MotionEvent transformEventOld(MotionEvent e, Matrix m) {
    long downTime = e.getDownTime();
    long eventTime = e.getEventTime();
    int action = e.getAction();

    int[] pointerIds = getPointerIds(e);
    PointerCoords[] pointerCoords = getPointerCoords(e);
    int metaState = e.getMetaState();
    float xPrecision = e.getXPrecision();
    float yPrecision = e.getYPrecision();
    int deviceId = e.getDeviceId();
    int edgeFlags = e.getEdgeFlags();
    int source = e.getSource();
    int flags = e.getFlags();

    // Copy the x and y coordinates into an array, map them, and copy back.
    float[] xy = new float[pointerCoords.length * 2];
