MTP Protocol Summary

MTP Protocol Spec

Add Some Feture:

1.Send Custom MTP Command

example:

@Test
public void testGetNumObjects() throws COMException {
    MTPDataset request = new MTPDataset();
    request.code = 0x1006;//Operation Code
    request.params = new int[]{0xFFFFFFFF, 0, 0x00000000}; //Params
    MTPDataset response = MTPHelper.getInstance().sendCMDWithoutDataPhase(device, request);
    long responseCode = response.code;
    int[] responseParams = response.params;
}

example:

    @Test
    public void testSetDevicePropValue() throws COMException {
        MTPDataset request = new MTPDataset();
        request.code = 0x1016;
        request.params = new int[]{0xD402};
        Buffer buffer = new Buffer();
        buffer.writeByte(0x5);
        buffer.writeShortLe('X');
        buffer.writeShortLe('B');
        buffer.writeShortLe('O');
        buffer.writeShortLe('X');
        buffer.writeShortLe(0);
        request.data = buffer.readByteArray(); //Friendly Name MTP Protocol String
        MTPDataset response = MTPHelper.getInstance().sendCMDWithOutData(device, request);
        long responseCode = response.code;
    }

@Test
public void testGetStorageIDs() throws COMException {
    MTPDataset request = new MTPDataset(0x1004);
    MTPDataset response = MTPHelper.getInstance().sendCMDWithInData(device, request);
    byte[] storageIdArr = response.data;
    long responseCode = response.code;
}

2.Register MTP Event

MTPHelper.getInstance().registerEvent(device, new MTPHelper.EventListener() {
    @Override
    public void onEvent(MTPDataset event, Exception e) {
        if (e != null) {
            e.printStackTrace();
            return;
        }
        //mtp event,example object added...
    }
});
