How to change Strings resource XML file programatically?

Question

I have some conditions in which I have to change some resources in strings.xml file. Is there a way to do that programatically, without pushing an updated version of the app?

You cannot change strings.xml strings as far as I know. Instead introduce two, or more, alternative strings there and use appropriate one where needed. — harism

every resource defined while creating an app, it is assigned an ID which can be found in R.java so until you don't have id, there is no way to modify any res file programmatically. I will suggest you should look for Shared Preferences — Jibran Khan

@harism The values cannot be known in advanced hence I cannot use alternative strings. — Basit

@JibranKhan Now that I've come to think of it, you're right. Those values are assigned at compile time and cannot be modified. Thank you for your response, I'd look for an alternate solution than modifying resource files. — Basit

No you cant. One solution is to use SharedPrefences instead.

It answers my question, thanks! I cannot use SharedPreferences in this case. Will have to opt for a different approach int this case.

You cannot change the values of any resources after the app has been compiled, as the references are generated at this time.

You will have to handle this using some logic directly in your code. Something like:

if (condition) 
   set something not from resources
else
   use resource for text

Yeah! Those resource IDs cannot be modified at run time. I'm opting a different option here. Thank you for your response.
