Hardcoded String

Hi Shiina,

this i a common warning and your app will run fine without creating an error.

If you go to app > src > res > values folder you will see a strings.xml file. Open it and see all the string resources of your project.

You can hardcode a String variable like this:

android:text="someText"

or you can create the value of the String as a reference to the strings.xml file so later on you will have the possibility to change the values inside the resource file without changing your code. If many String use a single String resourse, you just change one resourse value and all String in the code will change. Cool right. This is important if you create many layouts with different languages.

The minimalistic strings.xml resourse could look like this:

<resources>
    <string name="hardCodedStringName"> coolHardCodedStringValue </string>
</resources>

Inside your code you can reference the String resource this way:

android:text="@string/hardCodedStringName"

You can change the value of "hardCodedStringName" without changing the code of the reference.

Makes sense?
