Which countries and which languages will your app support? Review the major markets and identify the regions with the most significant potential for your app.
You usually want to offer an Android app for as many devices as possible. As a developer, you try to work as optimally as possible so that the program code runs well on all hardware configurations and the layout is shown as correctly as possible on all displays. Localisation is another step towards widespread use. This topic can be a little more challenging with WebView-based Android apps. Because it only shows one website, it doesn’t know which language the user actually speaks.
However, the WebViewGold Android App Template is quite smart in terms of Multi-Language Handling:
Set APPEND_LANG_CODE to true if you want to extend URL request by the system language like ?webview_language=LANGUAGE CODE
