Android to replace String.xml values at run time?

Question

As per requirement, now all the values of my String.xml file come from the server.
And i need to handle the same in the application and these values are dynamic. what is recommended way to do this.
As per design i save these values in database and on application launch i cache the data in the hashmap and i use the map throughout the application. I have made a service that update the database in the background.

Is there any better way than this?

shared preferneces is may useful.Update shared preferences values when you get data from server and use the values from shared preferences — Narender Reddy

i dont think you can do that. Those are hard coded and cannot be changed dynamically — Tasos

That's why i save the data from the server into database and then use hashmap..but my concern is that there may be possible that, i call tell the system to pick the values from x file and then at run time when i need, i will change that file — user3586231

Solution to your problem is make use of either Shared Preferences or Local Database.

Updating String.xml is not an good programming practice.

Shared Preferences is best solution to your problem and it is easy to use.

Updating string.xml is impossible at runtime

But it is ease to update the database instead of share preference..and with the help of query it is easy to update a particular string resource.

I think you are implementing right way except using hashmap. If data is large or grow in future it will slow down your app. You can use array and get string by directly accessing its index. Thanks.

But, searching in hash-map is faster than Array-list.

Please share some link. In array you can directly access element by using index, but not in hash-map.

Ok, let me explain. Its your array so you do not need to search. you know index so can directly access element by its position and use it. I mean by using this approach you will improve performance for long time. Hope I explained.

We do not know the index of item, because data is in from of key-value pair.

Ramit Over a year ago

Then its fine, but think about this solution. It will improve performance it you can get indexed based data. In my app I used this approach earlier.
