  @AppLee I'm actually not using the OpenStore at all but just doing all my development work locally at the moment. I'm not using clickable because my app cannot be cross-compiled. It relies on a rust dbus crate that doesn't allow cross-compiling (see https://github.com/diwic/dbus-rs/blob/master/libdbus-sys/cross_compile.md for details).

  @mirroronthewall Porting android apps is not the best way to achieve your goal I think. The best course of action is to create a native app which can integrate libs or some algorithm from Open Source projects like the one you mentioned. AR and VR requires some work but it's doable, just need someone motivated and with enough time to do the job. If I win the lottery (but I don't bet) I'll be happy to try out the AR

  @dobey I only came across it recently and haven't looked into it properly, but does that mean that we can develop in Python+GTK with libhandy widgets?

  If we start with HERE, see their API first. We need search (address->coordinates), routing and reverse search (coordinates->address). Pure Maps uses REST API to communicate with the servers. So, check their REST API and see if you can get trucks support if you use it. Docs are at https://developer.here.com/documentation Routing at https://developer.here.com/documentation/routing/dev_guide/topics/request-a-simple-route.html If routing seems OK, then let's start with search. Its API at https://developer.here.com/documentation/geocoder/dev_guide/topics/what-is.html That API we will translate to code in https://github.com/rinigus/pure-maps/tree/master/geocoders , so Pure Maps will understand it

  Hello again First step: create an issue for Ubuntu Touch support: https://github.com/redox-os/orbtk/issues/100. I also start evaluating some libraries that could be used to implement that port.

  @poVoq Yes this is the easiest way to do it. If you search for the first release of my app this is what I used. But I had a limitation regarding self signed certificates. So I decided to create a C++ library to send HTTPS requests. Thanks for sharing your findings ; could be helpful for other

  @Flohack Yes the overall system seems quite easy, but the devil lies in the details. Starting from scratch would be reinventing the wheel when there are those nice existing NodeRed nodes. But they reference further NodeJS libraries and while all of that is probably not a big deal for an somewhat experienced Javascript developer, I am somewhat lost looking at it

  The developer of P2 is willing to add Ubports push notification support for XMPP clients, but it would need to be implemented by someone with Java knowledge. According to him it should be really easy though. On an unrelated note, this might also be a portable qt native xmpp client: https://github.com/ksiazkowicz/lightbulb

  Hi @supaiku! Your question is pretty broad, but lets try... Other ways of contributing to apps than writing code: reading code - some tasks like creating developer documentation, only needs you to read and understand the code helping with design creating art work like app icons making mock ups for new apps taking administrative burdens from developers by managing issues for example (being the maintainer of an app you know very well is possible without knowing how to code) help testing of course by joing the ubports qa and test telegram group or: more structured tests were nice in some cases, but someone would need to create that (infra)structure, either by creating and managing test tables, which are filled by testers or by setting up more advanced test managing systems (i.e. see http://www.systemtestportal.org/) translating apps maybe you find enough app devs around you to host a hackathon
