IBM Watson Alchemy API VerifyError

Question

I'm working on alchemy API. The Reference link used Alchemy Ref.

My Android code

 Thread thread = new Thread(new Runnable() {
        @Override
        public void run() {
            try
            {
                AlchemyLanguage service = new AlchemyLanguage();
                service.setApiKey("xxx - My API Key");

                Map<String,Object> param = new HashMap<String, Object>();
                param.put(AlchemyLanguage.TEXT, TextValue);
                DocumentSentiment sentiment = service.getSentiment(param).execute();
                SentimentValue = sentiment.getText();
                System.out.println(sentiment);

                SentimentType = sentiment.getSentiment().getType().name();
            }
            catch (Exception ex)
            {
                Log.d("Exception : " , ex.toString());
            }
        }
    });

    thread.start();
    Toast.makeText(MainActivity.this, SentimentType+" ", Toast.LENGTH_SHORT).show();

The program terminates during the initialization of the class

 AlchemyLanguage service = new AlchemyLanguage();

Log :

I ref'd this link [other ref](http://www.ibm.com/watson/developercloud/doc/alchemylanguage/tutorials.shtml#curlTutorial-keywords) and i could get results. and also the code doesn't run at `service.setApiKey("xxx");` @cricket_007 — SH7, Oct 15 '16 at 20:12
@cricket_007 - of course i used my actual api key just posted 'xxx' in stack overflow. — SH7, Oct 15 '16 at 20:19
Just curious :) Don't really know what to tell you, though. Does this code work in a standard Java app? Making a plain `Thread` object isn't really Android's way of doing things — OneCricketeer, Oct 15 '16 at 20:22
actually i tried **doInBackground** thread even that returns error. Just got a video link [youtube ref](https://www.youtube.com/watch?v=oiwhs1H9JVg) so followed that steps. — SH7, Oct 15 '16 at 20:25

This was a bug in the Java SDK. Make sure you use a version > 3.5.0 in gradle, use something like 3.7.1

'com.ibm.watson.developer_cloud:alchemy:3.7.1'

Then call AlchemyLanguage sentiment analysis:

AlchemyLanguage service = new AlchemyLanguage();
service.setApiKey("xxx - My API Key");

Map<String,Object> param = new HashMap<String, Object>();
param.put(AlchemyLanguage.TEXT, TextValue);

DocumentSentiment sentiment = service.getSentiment(param).execute();
System.out.println(sentiment);
