एंड्रॉइड से MySQL सर्वर पर डेटा कैसे भेजें?

आपको एपीआई लिखना होगा जहां आप एंड्रॉइड से डेटा पास कर सकते हैं और उस डेटा को एपीआई में ला सकते हैं और सम्मिलित क्वेरी का उपयोग करके डेटाबेस में स्टोर कर सकते हैं। एंड्रॉइड साइड पर आपको नीचे दिए गए कोड को करना होगा:

GetData (), PostData, DeleteData () के लिए मेरी कक्षा PutUtility। आपको बस पैकेज का नाम बदलने की जरूरत है

        }
        return Url;

    }

और इस वर्ग का इस तरह उपयोग करें। यह वर्ग स्वचालित रूप से इंटरनेट कनेक्शन करता है और आपको सर्वर से प्रतिक्रिया देता है:

    private class ServiceLogin extends AsyncTask<String, Void, String> {

            ProgressDialog mProgressDialog;
            private String res;

            @Override
            protected void onPreExecute() {
                mProgressDialog = ProgressDialog.show(LoginActivity.this,
                        "", "Please wait...");
            }

            @Override
            protected String doInBackground(String... params) {
                res = null;
                PutUtility put = new PutUtility();

                put.setParam("UserId", params[0].toString());
                put.setParam("Latitude", params[1].toString());
                put.setParam("Longitude", params[2].toString());
                put.setParam("DateTime", params[3].toString());

                try {
                    res = put.postData("INSERT URL of API HERE");
                    Log.v("res", res);
                } catch (Exception e) {
                    e.printStackTrace();
                }
                return res;

            }

            protected void onPostExecute(String res) {
                //"Here you get response from server in res"

            }
        }

अब आप इस सेवा को बटन क्लिक पर कॉल कर सकते हैं और नीचे की तरह सेवा में डेटा सम्मिलित कर सकते हैं:

new ServiceLogin().execute(pass four parameters here);

आशा है कि यह आपकी मदद करेगा

संपादित करें:

डेटा डालने के लिए यह सरल PHP एपीआई है

<?php include('connection.php');

$return_arr = array();

 $UserId=($_POST['UserId']);
 $Latitude=($_POST['Latitude']);
 $Longitude=($_POST['Longitude']);
$DateTime=($_POST['DateTime']);


        $user_register_sql1 = "INSERT INTO `activity`(`Id`,`UserId`, `Latitude`,`Longitude`,`DateTime`) values (NULL,'".$UserId."','".$Latitude."','".$Longitude."','".$DateTime."')"; 
             mysql_query($user_register_sql1);
             $row_array['errorcode1'] = 1; 

}
?>
