How to localization app name on android platform

If it doesn't already exist, create a folder \Assets\Plugins\Android\res\values-xx for each additional language you want to support. Substitute "xx" with the two letter language (not country!) code.

Also make one without a language code (\Assets\Plugins\Android\res\values) which will be the default one, if your device doesn't match any of the languages you created.

So you would end up with these folders:

\Assets\Plugins\Android\res\values

\Assets\Plugins\Android\res\values-es

\Assets\Plugins\Android\res\values-nl

In each of those folders, create an xml file called strings.xml containing this:

 <?xml version="1.0" encoding="utf-8"?>
 <resources>
     <string name="app_name">Hello World</string>
 </resources>

Let's say the default language is going to be English, so this xml with "Hello World" would go into the values folder. Another one with "Hola Mundo" for the values-es folder and "Hallo Wereld" in the values-nl folder.
