Du skal skrive Api, hvor du kan videregive dataene fra Android og og hente disse data i Api og gemme i databasen ved hjælp af indsæt forespørgsel. På Android-siden skal du gøre nedenstående kode:
Min klasse PutUtility til getData(), PostData, DeleteData(). du skal bare ændre pakkenavn

Og brug denne klasse sådan her. denne klasse Foretag automatisk internetforbindelse og giver dig svar fra serveren:
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"
}
}
Nu kan du kalde denne tjeneste ved at klikke på knappen og indsætte data i tjenesten som nedenfor:
new ServiceLogin().execute(pass four parameters here);
Håber dette hjælper dig
EDIT:
Dette er simpelt PHP API til at indsætte data
<?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;
}
?>
