Answer 1

The resources are pretty much set in stone, so you can't modify them at runtime. If you need to store some new strings, use SharedPreferences or SQLite .

Answer 2

I don't think you want to do that. If you are trying to store a value in a persistent way, take a look at SharedPrefences . Google has a good introduction to it here .

Answer 3

It is not possible to modify the resources of an APK during runtime.

Answer 4

You can't edit those resources directly. You might want to look into sharedpreferences http://developer.android.com/reference/android/content/SharedPreferences.html or creating your own xml file.

Answer 5

You cant edit a resource or add a resource once the code is compiled. I dont know exactly what setResource does, but once your program is compiled, android builds the gen files which designate a certain amount of space for those variables, changing the variable once written would cause overflow or outofbounds errors with memory. If you want persistent values try using the SharedPrefs, SQL or even your own XML stored within the directory of the app, which you could set to only be readable by your app.
