Start for Project Translate
Before start, I highly recommended you to use the offline tools for project translate. Here provides the newest version of ax2j.jar, it has a simple GUI and has both content translate function and project translate function. Use the offline tools can reduce server load pressure, it's important for a completely free open source project.
Compress your Eclipse/Android Studio project to .zip file.
Because of the server cost, .zip file has size limit 10 Mb. Here are some tips to help you reduce your project.zip size:
Necessary files: res folder is necessary, and the AndroidManifest.xml which declares your theme too. If you have custom view, src/path-to-your-custom-view is also necessary.
Unnecessary files: All the other files can be remove from your project.zip, especially for Android Studio project, removing your .gradle and build folders is the most effective thing to reduce the size.
Notice: Currently project translate will scan the files as it is a default project structure. That means if you change the files location of java, res and AndroidManifest.xml by gradle of something else, project translate may not find them out.
Upload your project.zip:Upload
Check the XML files that are going to be translated:
