Android phone number attribution to the query _android

A simple demo, from aggregation data to apply for mobile phone number attribution to the data interface;

Enter the query number in the EditText, get the number and use HttpURLConnection to get the JSON data in the child thread, then parse;

After data acquisition is complete, update the UI in the main thread to show the number attribution information.
