mversion | cross packaging module version bumper | JSON Processing library

Don't know if this the right place to ask this question but desperately need all the help I can get.

I have an android device with integrated Futronic fingerprint scanner. I have been able to communicate with the scanner and gain access to it using the usb host mode.

I have the below log on the Logcat showing am able to communicate with the scanner

(Disclaimer: the title of this question is probably too generic and not helpful to future readers having the same issue. Probably, it's just because I can't phrase it properly that I've not been able to find anything yet to solve my issue... I engage in modifying the title, or just close the question once someone will have helped me to figure out what the real problem is :) ).

I receive a string in input that contains two information of my interest:

• A version name, which is 3.1.build and something else later
• A build id, which is somenumbers-somenumbers-eitherwordsornumbers-somenumbers

I need to extract them separately.

I have an input which may come in 4 different ways:

Sample 1: v3.1.build.dev.12345.team 12345-12345-cici-12345 (the spaces in between are some \t first, and some whitespaces then).

Sample 2: v3.1.build.dev.12345.team 12345-12345-12345-12345 (this is very similar than the first example, except that in the second part, we only have numbers and -, no alphabetic characters).

Sample 3:

I have 3 dropdowns containing values that are populated on page load

So lately I have been working with smart cards that hold some information and what I am trying to achieve here is to fetch this data from these smart card using a smart card reader through any Android Smartphone. I have been using a HID OMNIKEY 3021 USB smart card reader which would read these card(And I know this reader works with these cards through windows apps because I have personally tested this)

Now Android provides USB Host that makes it possible to read any USB Host provided the Android Smartphones supports it.

And I am trying to use these classes provided by USB Host to reach out to the data inside this card.

My code to detect any USB Host :

The following snippet works fine:

I am creating a QTableView formed of 6 columns that inserts specific values by calling a dialog. When I compile the project I receive the following errors in the file 'itemcameracalibrationdata.h':

note: candidate expects 6 arguments, 0 provided

note: candidate expects 6 arguments, 1 provided

For completeness I am including below both the 6 variables and the dialog file: Below the itemcalibrationdata.h

I am trying to figure out the pre-base64-encoded stats of a string as well as the algorithm used to encode it so I can edit a decoded json string and then re-encode with the same encoding.

I am able to decode the original. But am not able to replicate the encoding.

Example of encoded text:

it's me again with a Android Things question

This time I want to connect a 7" display via HDMI and USB to my Raspberry Pi 3 (running with Android Things 0.5.1)
Here the link to display: 7" HDMI LCD (C)

I also followed the instruction on the manual and added the lines to the config.txt which is located in the root of my sd-card
