我想制作一个Android应用程序，谷歌电子表格将成为我的服务器。我能够通过谷歌表格将数据发布到服务器（谷歌电子表格），但无法从该电子表格中获取数据。 我的代码是

公共类ContactActivity扩展了ActionBarActivity {

public static final MediaType FORM_DATA_TYPE
        = MediaType.parse("application/x-www-form-urlencoded; charset=utf-8");
    public static final String URL="https://docs.google.com/forms/d/e/" +
        "XXXXXXXXX/formResponse";
    public static final String NAME="entry.XXXXXXXX";
public static final String PHONE="entry.XXXXXXXX7";
public static final String EMAIL="entry.XXXXXXXX";

private  Context context;
private EditText name;
private EditText ph;
private EditText email;

@Override
protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_contact);
    context =this;

    Button sendButton = (Button)findViewById(R.id.submit);
    name = (EditText)findViewById(R.id.name);
    ph = (EditText)findViewById(R.id.phone);
    email = (EditText)findViewById(R.id.email);

    sendButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            if(TextUtils.isEmpty(name.getText().toString()) ||
                    TextUtils.isEmpty(ph.getText().toString()) ||
                    TextUtils.isEmpty(email.getText().toString()))
            {
                Toast.makeText(context,"All fields are mandatory.",Toast.LENGTH_LONG).show();
                return;
            }
            if(!android.util.Patterns.EMAIL_ADDRESS.matcher(email.getText().toString()).matches())
            {
                Toast.makeText(context,"Please enter a valid email.",Toast.LENGTH_LONG).show();
                return;
            }

            PostDataTask postDataTask = new PostDataTask();

            postDataTask.execute(URL,name.getText().toString(),ph.getText().toString(),email.getText().toString());
        }
    });
}

private class PostDataTask extends AsyncTask<String, Void, Boolean> {

    @Override
    protected Boolean doInBackground(String... contactData) {
        Boolean result = true;
        String url = contactData[0];
        String n = contactData[1];
        String p = contactData[2];
        String e = contactData[3];
        String postBody="";

        try {

            postBody = NAME+"=" + URLEncoder.encode(n,"UTF-8") +
                    "&" + PHONE + "=" + URLEncoder.encode(p,"UTF-8") +
                    "&" + EMAIL + "=" + URLEncoder.encode(e,"UTF-8");
        } catch (UnsupportedEncodingException ex) {
            result=false;
        }

        try{

            OkHttpClient client = new OkHttpClient();
                            RequestBody body = RequestBody.create(FORM_DATA_TYPE, postBody);
            Request request = new Request.Builder()
                    .url(url)
                    .post(body)
                    .build();
            Response response = client.newCall(request).execute();
        }catch (IOException exception){
            result=false;
        }
        return result;
    }

    @Override
    protected void onPostExecute(Boolean result){
                    Toast.makeText(context,result?"Message successfully sent!":"There was some error in sending message. Please try again after some time.",Toast.LENGTH_LONG).show();
    }

}
