Parrot

Parrot is a gradle plugin that allows your app to speak multiple languages, without the hassle of working with multiple resources, using the translation editor or ordering an expensive translation from AS/IDEA

It leverages the Google Translate API in order to translate your string resources into all the languages specified in the configuration.

Installation

Get a Google Cloud account and get your Translate Api Key.

https://cloud.google.com/translate/

Add the following to your build.gradle:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.carlospaulino:parrot:0.1.0'
    }
}

// Apply below the Android Application Plugin (com.android.application)
apply plugin: 'com.carlospaulino.parrot'

Parrot configuration must be done in the parrot closure:

parrot {

    // Default Google Translate Api Key.
    // You can also set the environmental variable GOOGLE_TRANSLATE_API_KEY with the key
    apiKey = "MY_API_KEY"

    // Language Parrot is translating from in ISO 639-1
    sourceLanguage = "en"

    // Languages Parrot is translating to in ISO 639-1
    destinationLanguages = [ "es", "fr", "de" ]

    // Ignore cache and always perform translations
    alwaysTranslate = false
}

You can see the full list of languages here: https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes

ProTips

If you think the translation that was auto generated is not accurate enough you can just override it, by setting the resources in the correct language folder. For example if you are translating to Spanish just create the file: values-es/strings.xml and add the resource. Parrot will skip that resource and not perform the translation.

<resources>
    <string name="app_name">Mi Aplicación es la mejor</string>
</resources>

You can also view the translated resources before they are merged by looking in your build folder. {appModule}/build/generated/res/rs/{flavor}/{buildType}/values-{lang}/translated-strings.xml
