Working with the API

Translate text as configured

Open MainActivity.java and add the following to the bottom of onCreate():

Amplify.Predictions.translateText("I like to eat spaghetti",
    result -> Log.i("MyAmplifyApp", result.getTranslatedText()),
    error -> Log.e("MyAmplifyApp", "Translation failed", error)

Open MainActivity.kt and add the following to the bottom of onCreate():

Amplify.Predictions.translateText("I like to eat spaghetti",
    { Log.i("MyAmplifyApp", it.translatedText) },
    { Log.e("MyAmplifyApp", "Translation failed", it) }

Open MainActivity.kt and add the following to the bottom of onCreate():

val text = "I like to eat spaghetti"
    val result = Amplify.Predictions.translateText(text)
    Log.i("MyAmplifyApp", result.translatedText)
} catch (error: PredictionsException) {
    Log.e("MyAmplifyApp", "Translation failed", error)

Open MainActivity.java and add the following to the bottom of onCreate():

RxAmplify.Predictions.translateText("I like to eat spaghetti")
        .subscribe(
            result -> Log.i("MyAmplifyApp", result.getTranslatedText()),
            error -> Log.e("MyAmplifyApp", "Translation failed", error)
