Mäh W.<p>Hi Android <a href="https://chaos.social/tags/reverseengineering" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>reverseengineering</span></a> friends. I am new in this field and wanted to try something out... it's probably pure basics. I got an APK and ran `strings` on the `classes.dex` file. There's an interesting URL embedded which might be related to downloading firmware. When running curl, I get two `301 Moved Permanently`. Manually resolving to the new location results in an HTML file with a "Page not found" message so I guess that there's basic auth. How can I decompile the code around that string?</p>
