localization of assets files

Question

I have several html files in assets folder. How can I localize them? Is my only option to put some hardcode to pick the right file based on locale?

Answer 1

This isn't supported directly but here is what I have done...

Separate your files into groups by country code (like what you would do for normal resource files) and then create a localized string in each of your localized string.xml files called something like "prefix" (where prefix would be "en" for English for example).

Then when you build your asset filenames simple use something like getString("prefix") + "-" + "<name-of-asset->.

At least some variation of the above should work for you.

Answer 2

Put your files into the assets folder with local suffix. Define a String resource 'myLocalizedFileName' for every file and get the filename via R.string.myLocalizedFileName.

Example:

Folder structure:

assets/ assets/help.html assets/help_de.htlm 

String resources for every language in res/values/strings.xml:

<resource>   <string name=helpFile>help.html</string> </resource> 

WebView calling:

public class HelpActivity extends AppCompatActivity {   protected void onCreate(Bundle savedInstanceState) {     ...     findViewById(R.id.helpWebView)       .loadUrl("file:///android_asset/"           + getString(R.string.helpFile));   } }
