In IBM Watson try out virtual device, it is working perfectly.

But in my Android app, it's not displaying. I think, there is something wrong in my Android code, please help. [edited code image]

Answer 1

Based on the example response from Watson Assistant API

{
  "intents": [
    {
      "intent": "hello",
      "confidence": 0.9755029201507568
    }
  ],
  "entities": [],
  "input": {
    "text": "Hello"
  },
  "output": {
    "generic": [
      {
        "response_type": "text",
        "text": "Hello! What can I do for you?"
      }
    ],
    "text": [
      "Hello! What can I do for you?"
    ],
    "nodes_visited": [
      "greeting"
    ],
    "log_messages": []
  },
  "context": {
    "conversation_id": "a96ec62f-773c-4e84-8be9-f9dbca9f83d0",
    "system": {
      "dialog_stack": [
        {
          "dialog_node": "root"
        }
      ],
      "dialog_turn_counter": 1,
      "dialog_request_counter": 1,
      "_node_output_map": {
        "greeting": {
          "0": [
            0,
            0
          ]
        }
      },
      "branch_exited": true,
      "branch_exited_reason": "completed"
    }
  }
}

I think the issue is with this line of Android code

response.getText().get(0);

Once the response is received you are trying to read the first element under getText.get(0). As it can be an array or an object of arrays, you should loop through it to read every value.

Replace

final String outputText = response.getText().get(0); 

with

String outputText = "";
                    int length=response.getText().size();
                    Log.i(TAG, "run: "+length);
                    if(length>1) {
                        for (int i = 0; i < length; i++) {
                            outputText += '\n' + response.getText().get(i).trim();
                        }
                    }
                    else
                       outputText = response.getText().get(0);
