title: Any collaborative tool/website to localize an Android app?
body: <p>My open source Android application has internationalization done the Android way, with strings.xml files.</p>
  
  <p>The community has many people from many countries, and they are willing to contribute/improve translations using a collaborative website.</p>
  
  <p>There is <a href="https://translations.launchpad.net" rel="noreferrer">Launchpad</a> but it only supports the gettext format so we would have to use scripts, not very convenient.</p>
  
  <p>What website is convenient for translating open source Android applications?<br>
  Anybody must be able to start contributing without any sort of prior approval.</p>
