Mr.AndroidShin Dev Tools is run by one person — a solo Android developer. If you've found a bug, spotted something wrong or misleading in a tool, or want a utility that doesn't exist here yet, I genuinely want to hear about it. Reader feedback is where most of the roadmap comes from. The fastest way to reach me is email.
What's useful to include
To help me act on a message quickly, a little context goes a long way:
- For a bug: which tool, what you entered, what you expected, and what happened instead. A copy of the input that broke it is ideal.
- For a wrong result: the tool, the value you used, and the answer you believe is correct — with a source if you have one. Accuracy matters to me and I'll fix confirmed errors quickly.
- For a new tool or guide: the problem you're trying to solve. The best requests describe a chore you keep hitting in your own Android work — those often become the next page on the site.
- For rendering issues: your browser and OS, since a few tools depend on modern browser features.
What to expect
I read every message, but this is a one-person site run alongside building apps, so I can't always reply immediately — thank you for your patience. Confirmed bugs and factual corrections get priority. Feature requests that would help other Android developers, not just a single use case, are especially welcome and are the most likely to ship.
A note on privacy
The tools on this site run entirely in your browser and don't collect your inputs, so there's nothing for me to look up on your behalf — if you're reporting a problem, please include the details above rather than assuming I can see your session. For how the site itself handles data and advertising cookies, see the privacy policy. To learn more about who runs the site and why, see the about page.
