@SharedPref should support Set<String> #264
Description
Activity
That's something we considered. The problem is that, as you can see [here](http://developer.android.com/reference/android/content/SharedPreferences.html#getStringSet(java.lang.String, java.util.Set<java.lang.String>), those methods appeared in API Level 11. So that means we should provide an alternate implementation for pre Android 11 runtimes.
I think it's better, even if you don't provide an alternate impl, to support it. Of course, converting from one String to Set and back on pre11 would bring even more value from AA.
How'd you convert Set => String ? We need a separator, but I'm not sure there's a good separator.
You need an escaping mechanism (e.g. '') and then any char would do. Make sure that for example | is your separator, | resolves to | and \ resolves to .
Or go for a long string that regular users would definitely use in their own strings.One could use json to serialize StringSet to String
Already implemented. :)
It is my understanding that SharedPreferences has getStringSet() / putStringSet() to allow retrieval of several Strings at once.
An annotated @SharedPref interface should allow a return type of Set
