Code:

    private void googleTranslate() {
        new Thread(new Runnable() {
            @Override
            public void run() {
                //Translate translate = TranslateOptions.getDefaultInstance().getService();
                Translate translate = TranslateOptions.newBuilder().setApiKey("AIzaSyAuPO3rl-CClveK6XulCapCITeSONanpVA").build().getService();
                String sourceLanguage = "en";
                String targetLanguage = "zh-CN";
                TranslateOption srcLang = TranslateOption.sourceLanguage (sourceLanguage);
                TranslateOption tgtLang = TranslateOption.targetLanguage (targetLanguage);
                // Use translate `model` parameter with `base` and `nmt` options.
                TranslateOption model = TranslateOption.model("nmt");

                String sourceText = "Robinson Crusoe is a real hero. " +
                        "He almost has everything needed for becoming a successful man, " +
                        "such as his excellent creativity, great working capacity, courage, and persistence in overcoming obstacles. " +
                        "However, Robinson Crusoe is not a perfect man. " +
                        "He also has shortcomings. " +
                        "He was such a coward when he encountered a storm the first time. " +
                        "He sweared and repented yet ate his words and sailed on after the storm. " +
                        "By showing Robinson’s shortcomings, Daniel Defoe made Robinson a real person. " +
                        "After all, no one is perfect. " +
                        "Robinson Crusoe can not only lead the ambitious ones to success, but also guide average people to face up to life. " +
                        "This is the significance of the study of Robinson Crusoe";
                Log.e("MainActivity", "googleTranslate.............................1");
                Translation translation = translate.translate(sourceText, srcLang, tgtLang, model);
                Log.e("MainActivity", "Source Text:.............................."+sourceLanguage+"..............."+sourceText);
                Log.e("MainActivity", "TranslatedText.............................."+targetLanguage+"............"+translation.getTranslatedText());
            }
        }).start();
    }

Result after running:

original language

Source Text:..............................en...............Robinson Crusoe is a real hero. He almost has everything needed for becoming a successful man, such as his excellent creativity, great working capacity, courage, and persistence in overcoming obstacles. However, Robinson Crusoe is not a perfect man. He also has shortcomings. He was such a coward when he encountered a storm the first time. He sweared and repented yet ate his words and sailed on after the storm. By showing Robinson’s shortcomings, Daniel Defoe made Robinson a real person. After all, no one is perfect. Robinson Crusoe can not only lead the ambitious ones to success, but also guide average people to face up to life. This is the significance of the study of Robinson Crusoe

translated language

TranslatedText.........................................en-CN............Robinson Crusoe yes true hero. He has almost everything it takes to be a successful person like his brilliant creativity, great work ability, courage and persistence to overcome obstacles. However, Robinson Crusoe is not a perfect person. He also has flaws. When he first encountered the storm, he was a coward. He swore and repented, ate his words, and sailed after the storm. By showing Robinson's flaws, Daniel Defoe made Robinson a real character. After all, no one is perfect. Robinson Crusoe can lead not only to ambitious success, but also to ordinary people to face life. Here's what the study of Robinson Crusoe means

problems encountered

3.Error:Failed to resolve: com.google.cloud:google-cloud-translate:0.20.1-alpha

The above problem occurs after adding the following dependencies according to the official website abbreviation

Solution:

将 compile group: 'com.google.cloud', name: 'google-cloud-translate', version: '0.20.1-alpha' 替换为 compile 'com.google.cloud:google-cloud-translate:1.3.1'

4.Execution failed for task ':app:transformClassesWithDexForOffcialSiteDebug'.

Solution:

Allow multiDex in build.gradle

android {

    defaultConfig {
        ...

        // Enabling multidex support.
        multiDexEnabled true
    }
    ...
}

6.com.google.cloud.translate.TranslateException: The request is missing a valid API key.

Reason: Originally, TranslateOptions.getDefaultInstance().getService() will call the value of GOOGLE_API_KEY configured on the computer by default, but I don't know which step went wrong. If it is not configured, you can use the following method to dynamically set the API Key

Solution:

Translate translate = TranslateOptions.getDefaultInstance().getService();

Become dynamic to set app key from code

Translate translate = TranslateOptions.newBuilder().setApiKey("AIzaSyAuPO3rl-CClwwwkeXulCapCITeSONanpVA").build().getService();
