getString Outside of a Context or Activity

Question

I\'ve found the R.string pretty awesome for keeping hardcoded strings out of my code, and I\'d like to keep using it in a utility class that works with models i

Answer 1

You can do this in Kotlin by creating a class that extends Application and then use its context to call the resources anywhere in your code

Your App class will look like this

 class App : Application() {
    override fun onCreate() {
        super.onCreate()
        context = this
    }

    companion object {
        var context: Context? = null
            private set
    }
}

Declare your Application class in AndroidManifest.xml (very important)

To access e.g. a string file use the following code

App.context?.resources?.getText(R.string.mystring)
