Create an Android app for Syncthing as part of the Syncthing Tray project by mkittler

Description

There's already an app but code/features already in Syncthing Tray could be reused to create a nicer app with additional features like managing ignore patterns more easily. The additional UI code for the app could then in turn be re-used by other parts of Syncthing Tray, e.g. to implement further steps in the wizard as requested by some users. This way one "UI wrapper codebase" could serve GNU/Linux, Windows and Android (and in theory MacOS) at the same time which is kind of neat.

Goals

• DONE: Learn more about development for Android and development of UIs with Qt Quick
• DONE: Create an experimental app reusing as much existing Syncthing Tray code as possible
• DONE: Build Syncthing as a library also for Android and use it in the app (already done but needs further testing and integration with the rest of the app configuration)
• DONE: Update the Syncthing Tray website, documentation
• DONE: Extend the app so it has at least a start page and an import
• Update forum thread
• DONE: Upload an experimental build on GitHub
• Extend the Syncthing API to download single files on demand (instead of having to sync the whole directory or use ignore patterns)
• Bring back parts of the newly developed mobile UI back to Syncthing Tray on the desktop to fully benefit from the cross-platform development
  • Add UI to add/edit folders and devices in desktop tray app
  • Add UI to show out-of-sync items in desktop tray app
  • Create an alternative "AppWindow" tailored for desktop platforms reusing UI components developed for the mobile app

Resources

• Android SDK/NDK and emulator
