以下是我的源代码：

public void Login() {
        SharedPreferences sharedPreferences =  getSharedPreferences("Sessions", Context.MODE_PRIVATE) ;
        SharedPreferences.Editor editor =  sharedPreferences.edit();
        EditText EmailAddress = (EditText)findViewById(R.id.Email);

            EditText txtPassword = (EditText)findViewById(R.id.Password);
            final String Email = EmailAddress.getText().toString().trim();
            final String Password = txtPassword.getText().toString().trim();
            Globals globals = new Globals();
            final ProgressDialog ringProgressDialog = ProgressDialog.show(Login.this, "Please wait ...", "Validating User", true);
            ringProgressDialog.setCancelable(true);
            RequestQueue queue;

            StringRequest stringRequest = new StringRequest(Request.Method.POST, "http://www.jobspot.co.ke/Employee/LoginFuncx",
                    new Response.Listener<String>() {
                        @Override
                        public void onResponse(String response) {
                            ringProgressDialog.dismiss();
                            if(Html.fromHtml(response).toString().trim().equals("True"))
                            {
                                SharedPreferences  sharedpreferences = getSharedPreferences("MySessions", Context.MODE_PRIVATE);
                                Intent myIntent = new Intent(Login.this, MainActivity.class);
                                try {

                                    JSONObject object = result.getJSONObject(result.length()-1);
                                    String EmployeeNo = object.getString("EmployeeNo");
                                    String EmployeeName = object.getString("FirstName")+" "+object.getString("OtherNames");
                                    SharedPreferences.Editor editor = sharedpreferences.edit();

                                    editor.putString("jobSpotEmployeeNo", EmployeeNo);
                                    editor.putString("jobSpotEmployer", EmployeeName);
                                    editor.commit();

                                    Login.this.startActivity(myIntent);
                                }catch (JSONException e){

                                }


                            }else {
                                Toast.makeText(getApplicationContext(), Html.fromHtml(response), Toast.LENGTH_LONG).show();

                    // do not add anything here

问题在于我的设备。网络模式设置为仅限GSM。我将它改为GSM / WCDMA auto并且运行正常。使用Retrofit Http库也会出现同样的问题。 Retrofit返回 Retrofit.Retrofit error 。希望这有助于某人

为什么我在使用移动互联网时会遇到Android Volley ClientError
