XML string resources vs Java Constant Strings?

Question

I have a String is like String data="apps";

i know loading String in Android in two ways..

First one is

so it is a constant i defined it as

public static final String data="apps";

And another type is defing it in res/vslues/strings.xml file like..

<string name="data">apps</string>
<string name="hello_world">Hello world!</string>

if i want to use it..

for the first way ClassName.data

for second way context.getResources().getString(resourceid)

Question:

so now my question is I want to use same String in 30 times in different classes.And I have more number of variables.so which will load faster and take lesser memory in the above methods..

Answer 1

However, speed shouldn't really be an issue in either case. I would recommend organizing based on what makes sense.

Constants class

Put strings constants that will be used internally, like database column names or other keys.

strings.xml

Put strings that are displayed for the user. This way you can take advantage of localization, etc.

As per requirement you should be prefer second approach means XML based.
