Localize your Android apps via Google Translate, the easy way!
Smartphones are increasingly used all over the globe, and I expect English to be a minority language among their users pretty soon. Fortunately, both Android and the iPhone are designed from the ground up for multilanguage localization. It's basically a two-step process for both:
There are various translation services you can pay for step 2. And if you're serious about it being a good translation, you probably want to do that. But for a first iteration, or a quick-and-dirty app, why not just use Google Translate?
"Because that would be really tedious" is one answer. Aha, but there is a JavaScript API for Google Translate! And hence I give you this one-page, two-click solution for translating an Android strings file into another language:
There now. Was that so hard? Just paste your initial strings file into the top text box, select your From and To language, hit "Translate", sit back for 30 seconds, let Google Translate work its magic, et voila: your translated strings file appears down below.
Still too lazy to get it up and running yourself? Fine, here's a fully functional version running on my iTravelFree app's App Engine service:
http://itravelapp.appspot.com/static/localizer.html
Right now it only handles Android strings-file syntax, but I'll be adding iPhone soon enough. (And really, if you know anything about JavaScript and XML, it won't be hard for you to customize it yourself.)
Hope y'all find it useful -

- Move all the strings you show your user from code into a strings file. You do this by using activity.getString() in Android, and the NSLocalizedString macro followed by a bit of command-line voodoo in Objective-C.
- Translate the strings file into another language.

Androlate - An Eclipse plugin which translates your string resources using Google Translate. http://www.cicadalane.com/node/394
I have updated this to include string-array's and take out escaped characters. at http://uzitech.com/translator.php

For Android app translation, you should consider the web-based localization platform https://poeditor.com/
It's fast and collaborative and has its own API and offers users a translation memory.

I just jumped into an assumption (logical I hoped) that what her sounds meant were words of goodwill, either have a good day or enjoy the flight. “You’re now just few hours from the World Cup. It’s our pleasure to bring you safely in Germany,” she then translated please visit after the cryptic words.
This article provides a practical guide for localizing Android apps using Google Translate. It simplifies the process into two steps: moving strings from code into a strings file and using Google Translate for translation. This practical approach is beneficial for app developers on tight schedules or budgets. Abogado de Accidentes Camiones Grande
