Fixed algorithm for obtaining permission to communicate with USB device. Obtaining permission algorithm is encapsulated in FTDI Class D2xxManager. So we had to implement Activity.onResume() in our application. In onResume() method, we create a trend for automatic connection just in case that connected  device have obtained permition. On device close we have destroy a trend for automatic connection.
class DlReader v1.7
- Added method getNumOfDlDevices()
example (app) v1.7

- in ComProtocol.portWrite() from this version we use an nonblocking write() overloaded method from the FTDI class and we have implemented retry count (Consts.MAX_COMMUNICATION_BREAK_RETRIES times) on communication break. If the number of the communication break retries exceeded, raised DlReaderException have Consts.DL_READER_IS_NOT_CONNECTED err_code and usb device is closed. This algorithm solve usb otg device disconnect detection problem on the Runbo X5 and probably some other Android smart phones with usb otg port.

-Removed UI buttons "Device Open" and "Device Close"
-Implemented automatic opening and closing device regarding changes in class DLReader v1.5.
-Automatic opening and closing implemented in class ReaderConnectionStatus. D-Logic uFR device is automaticaly opened when attached to the Android system. D-Logic uFR device is automaticaly closed on detaching from the system.

In DlReader.open() method added DlReaderException which will be thrown if there is already only one opened D-Logic device attached. Instance of the DlReaderException have: err_code = Consts.DL_READER_GENERAL_EXCEPTION and  detailMessage = "There is already opened D-Logic devices."
