Regarding the """open source""" via google market issue: could you please make sure the app also makes it into
https://f-droid.org/ or explain why this would be inherently less safe? I was just told that f-droid promises verifiability of installed apps but through the idea in here without searching this myself but think it is a big trust issue.
the key issue for me is that it needs to be easy to keep up to date with the recent versions. we produce very frequent builds (sometimes several times a week) and i am looking to automate those as much as possible with gradle. right now, having a single place to publish the apk speeds up the whole process a lot. eventually the updates will become less frequent then the distribution issue can be adressed properly.
you can literally check out the source from github (git clone, gradlew build) and build it yourself. or you can download the signed apk from mycelium.com. of course you need to keep up to date when we release new builds. there will be several changes to the server API while we are in beta.
i don't know enough about the process at f-droid how fast they incorporate changes. i also doubt that we are elegible because of our license. i think f-droid signs the apks themselves. while highly unlikely any maintainer there _could_ inject any code they want. of course similar things can be said about google play, with the recent APK bugs in the wild. i would personally feel more comfortable with a release signed by the original developers.
i think the optimum way to do it would be for us to provide signed released and f-droid verifies that a certain git tag corresponds to this. i briefly scanned their forums and the process seems highly manual so far.
