Obsolete - coded for decommissioned version of the API. This app unmaintained since Feb 2011. Source code still available; all other links dead or empty.

Current status

I'm not actively maintaining Droidstack anymore, I guess real life just got in the way. Being in college and having a full time programming job leaves no room for hobby projects. Also, ever since the mobile-optimized web UI launched, I felt there was no need for an app like this anymore. Thus, I might be removing Droidstack from Google Play Store soon. I'll leave the open-source project up, so if anyone's willing to pick up where I left, be my guest (and please let me know).

In the future (once I finish college this summer), I'd like to either pick up development on Droidstack, or create a new, simpler app that only offers what the web UI doesn't (e.g. notifications).

Get Droidstack

Enter image description here

To get Droidstack, either:


Integrate with Droidstack! Check out how.

Droidstack is an Android app that allows you to browse Stack Exchange websites in a very cool, native kind of way, while keeping a Stack Overflow-like look & feel. The API functionality is powered by StackWrap4J. The awesome icon is created by the talented folk at androidicons.com.


I'm updating this Imgur album with fresh screenshots every once in a while: http://foghina.imgur.com/droidstack






I'm the only one currently working on this app. You can contact me here (comment/answer) or get my email address from here.


The app is built using Java. Tools: Eclipse and Android SDK (and a bit of GIMP and Inkscape) on Linux. The project is hosted on Google Code.

  • Why is this not appearing in the apps tab? :( – Felix Jun 7 '10 at 13:11
  • Finally, someone has released an android app! :) I'll check this out when I get home (when I can compile it and whatnot). Great start! – Bryan Denny Jun 7 '10 at 14:55
  • I'd love some feedback on how it works on other devices than mine! But don't get too excited -- all you can do is view question lists. You can't view actual questions or anything else yet. I'll try to update the app as much as I can although I have to study a lot for college right now. – Felix Jun 7 '10 at 15:04

    I'm concerned that it looks too much like Stack Overflow. – jjnguy Jun 8 '10 at 19:47
  • @jjnguy: How is that a concern? Can you elaborate? – Felix Jun 8 '10 at 21:35
  • @Felix There may be copyright issues. I dunno though, just thought I'd mention it. – jjnguy Jun 8 '10 at 23:59
  • @jjnguy: thanks for pointing that out. I added a mention about legal issues and I'm now waiting for an "official's" response – Felix Jun 9 '10 at 11:37
  • Tested on a HTC Legend, working pretty well. Nice work! – Michael B. Jun 12 '10 at 17:24
  • @Michael B.: Thanks, I'm glad it works for you :) I still have one week and two grueling exams to go, after which I'll be able to pick up development on Droidstack :) – Felix Jun 13 '10 at 15:08
  • @Felix same here, still have 2 exams this week, but I'm working on a BlackBerry one, since I have more experience on these device. – Michael B. Jun 13 '10 at 15:19
  • The app look amazing. It's a shame SOApi doesn't allow ask/answer questions ( afaik ) Otherwise I could use this while I'm not in front of my desk. – OscarRyz Jun 21 '10 at 23:46

    Having to add your account separately for each site is quite a pain. I am a member of too many sites! – Casebash Sep 30 '10 at 1:46

    @John it says that in the app's description in Android Market. The StackExchange API doesn't currently support writing any sort of post, hence you can't do it in Droidstack. However, when you're on a question / answer, you can press the menu button and choose to open that question in a browser window and do your posting from there. – Felix Dec 30 '10 at 18:34

    One nice thing would be to be able to refresh the icon for a site. Specifically, for when a site moves from beta to "released", and it gets a real icon. – eidylon Aug 23 '11 at 5:17

On the legal stuff,

Looking at your screen shots, your application looks good to me.

The purpose of the guidance in StackApps is to encourage people to diversify their apps and make them really kick ass on their platform. I know the issue is confusing but we are trying to steer people away from "I'm just gonna clone the website" or "I'm going to write the OFFICIAL Stack Overflow Android browser."

No reasonable person would look at your application and think "this is the Stack Overflow website I am looking at!" or "this must be an OFFICIAL Stack Overflow app!"

That's what we are looking for. Your app looks awesome. Good job!


It is the best Stack Overflow Android app I've seen. Would it be possible to support notifications whenever someone comments on or answers one of your questions?

Normally, on the website there is a little red circle with a number in it that shows you the number of unseen messages and answers.

Nice work Felix.


Generally a nice app. What I was missing was a way to set the user globally on all sites. Instead you have to set the active user for all the sites. I don't see the usefulness in being able to set different users on different sites... The best way would be to be able to log in, but you commented elsewhere that this is not yet supported by the API. I would see this to be the first priority when (if) it does!

I like the rep notification, but if you have active both the main site and the meta site for one site, you get 2 rep notifications for each rep increase on the main site. The rep on the meta site does not have a rep on it's own, it just showing the rep on the main site (except SO Meta which has its own). You should not trigger for the meta site on rep changes, unless you monitor the internal rep within the meta and not the rep number shown on the user profile.

I also noticed that YouTube links in the "Musical Practice & Performance" site were replaced with large placeholders for the video, but no video. See this answer.


The best Android app I have tested among 3 similar Android apps. Some suggestions and issues:

1- Why are the results fewer than the SO page for the same query? I searched for 'eventhandler' and 'page', I get 'No questions Here' on the app but 4 results on SO. If that's what the API returns, is the API limited?

2- If I have a single site, skip the screen where you choose it or make it an option. (I will never use other than SO). Add a choice to add sites inside further in the menu.

3- I don't see the number of search results.
