As a user I want to synchronise tasks data using taskserver

[robin92]

This is quite tricky and can be achieved using different approaches:

• taskwarrior native binary needs to compiled with gnutls support

  This is a preferred way allowing taking advantage of the taskwarrior itself with near to none implementation needed from our side. Gnutls is quite advanced project and compiling it for android won't be easy.

• implementing a taskserver protocol based on available Java utilities

  Acceptable solution which will cost us maintenance and is quite risk-prone. Especially at the early stages of application lifetime.

• forking taskwarrior and use other library which is known to work on android

There have been a couple of recent developments make the first approach (a native task binary on android, with gnutls) achievable almost out-of-the-box, using Termux (termux.com) and installing taskwarrior with a simple "apt install taskwarrior".

another, similar tw-on-android-with-sync is taskdroid (https://github.com/tshirtman/taskdroid) although there's no easy install for taskdroid + tw-binary, as the project is still in early development.

both taskdroid and termux require android >5; lolipop (which I don't have, and neither does 70% of the android phones "in the wild")

Using packages provided by termux I was able to synchronise with my taskserver from command line. However, application is not ready yet for the termux binary as it crashes due to hitherto unsupported values in exported tasks' parameters.

Getting it working will be my priority now.
