Remarks
Performs a selection of the next Applet on this channel that matches to the partial AID specified in the openBasicChannel(byte[] aid) or openLogicalChannel(byte[] aid) method. This mechanism can be used by a device application to iterate through all Applets matching to the same partial AID. If selectNext() returns true a new Applet was successfully selected on this channel. If no further Applet exists with matches to the partial AID this method returns false and the already selected Applet stays selected. <br>
Since the API cannot distinguish between a partial and full AID the API shall rely on the response of the Secure Element for the return value of this method. <br> The implementation of the underlying SELECT command within this method shall use the same values as the corresponding openBasicChannel(byte[] aid) or openLogicalChannel(byte[] aid) command with the option: <br> P2='02' (Next occurrence) <br> The select response stored in the Channel object shall be updated with the APDU response of the SELECT command.
