Answer 1

If you want get last value from Ubidots to your textview. You can try this, but u must set the textview first OnCreate

@Override
        protected void onPostExecute(Value[] variableValues) {
            // Update your views here

            String status = Double.toString(variableValues[0].getValue());
//this is textview for show last value from ubidots
            mBatteryStatus.setText(status);

        }
    }

Answer 2

Do as follows, save reference to TextView as member and use it in nested AsyncTask:

public class YourActivity extends Activity{

    private TextView textView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.your_activity_layout);
        textView = (TextView)findViewById(R.id.yourTextViewID);
    ...
    }

    private YourAsyncTask extends AsyncTask{
    ...
        @Override
        protected void onPostExecute(Value[] variableValues) {
            if(textView != null)
                textView.setText("your text");

         }
    }
}
