How to use PrettyTime in time4j library?

Question

I am receiving a text which is in seconds (e.g. 7261). I need to convert it to this format: 2h, 1m, 1s

I am using time4j library. According to their Github page, I am doing something like this:

val duration = Duration.of(7261, ClockUnit.SECONDS).with(Duration.STD_CLOCK_PERIOD)
val prettifiedDuration = PrettyTime.of(Locale.ENGLISH).print(duration)

However, I get this error:

06-22 11:50:52.133 12161 12244 E AndroidRuntime: java.lang.ExceptionInInitializerError
06-22 11:50:52.133 12161 12244 E AndroidRuntime:    at net.time4j.base.ResourceLoader.getInstance(ResourceLoader.java:167)
06-22 11:50:52.133 12161 12244 E AndroidRuntime:    at net.time4j.PrettyTime.<clinit>(PrettyTime.java:95)
06-22 11:50:52.133 12161 12244 E AndroidRuntime:    at net.time4j.PrettyTime.of(PrettyTime.java:198)

Any idea? or even, better solution?

Answer 1

So, I realized there is a separate library for Android projects: https://github.com/MenoData/Time4A

For Gradle, add this dependecy:

implementation("net.time4j:time4j-android:4.6-2020a")

And in your Application class, initialize the library:

class MyApplication : DaggerApplication() {

    override fun onCreate() {
        super.onCreate()
        ApplicationStarter.initialize(this, true)
    }
}

Then you can use it as described in the question.
