Android+mysql : Connection class returns a Null object

I am trying to connect my android login app to XAMP server(an Apache is running in local machine) through jtds jdbc. It seems the code fails to connect the server. Here's the code:
ConnectionClass.java

//String url = "jdbc:mysql://127.0.0.1/events-test";
public String un = "root";
public String password = "password";
public String db = "users";
#SuppressLint("NewApi")
public Connection CONN() {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
java.sql.Connection conn = null;
String ConnURL = null;
try{
Class.forName(driver);
ConnURL = "jdbc:jtds:sqlserver://" + "127.0.0.1" +";databaseName="+ db + ";user=" + un+ ";password=" + password + ";";
conn = DriverManager.getConnection(ConnURL);
}catch (SQLException se){
Log.e("ERROR", se.getMessage());
}catch (ClassNotFoundException e){
Log.e("ERROR", e.getMessage());
}catch(Exception e){
Log.e("ERROR", e.getMessage());
}

return conn;
}

z = "Please enter all fields........";
else
{
try{
Connection con = connectionClass.CONN();
if(con == null){

}else{
String query = "select * from users where user='"+emailstring+"'and password='"+passstring+"'";
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery(query);
while(rs.next())

}
return z;
}
#Override

progressDialog.hide();
}
}
}
I am getting this output: "Please, check your internet connection...." .
This message should fire up only when con = null.
How to resolve?

Android does not support MySQL OR SQL Server : -
You can Use Sqllite
https://www.tutorialspoint.com/android/android_sqlite_database.htm
Or you can Access MySQL by PHP :-
https://www.tutorialspoint.com/android/android_php_mysql.htm

I faced the same problem...
The main problem is in your ConnectionClass.
String url = "jdbc:mysql://localhost/events-test";
public String un = "root";
public String password = "password";
public String db = "users";
this was your code, well, when you are using root and localhost, it's creating the check your internet connection problem. so to solve it, you have to create a new user and instead of localhost, use the IP Address of your internet.
To create new user, if you are using phpmyadmin, click the privileges tab, there you see add user option. Create user there, give all database privileges to that user and save it. Then use the username and password instead of "root"and "password".
Now to get your IP address, go to command prompt, type ipconfig, you will find ip address. In your above code, instead of localhost, type your ip address, for example,
String url = "jdbc:mysql://192.168.0.12/events-test";
And you have to give internet access in the AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
This should solve your problem.

I would like to insert data to phpmyadmin from my android device

At the moment I can add users into the database through postman or emulator but I need to be able insert the data from actual android device .What adjustments do I have to take ? Please have a look at the code below

Android Database Select Query - Does not show all records

Hello I am beginner to android.I want to make a database connection to mssql server in my pc. I found example on the net.
I think I have something wrong in connection. Because I have two records in my User table. But this code only gives me first record in table.
Here is ConnectionClass.java :
import android.annotation.SuppressLint;
import android.os.StrictMode;
import android.util.Log;
import java.sql.Connection;
import java.sql.DriverManager;

String password = "123";

StrictMode.setThreadPolicy(policy);
Connection conn = null;
String ConnURL = null;
try {
Class.forName(classs).newInstance();
ConnURL = "jdbc:jtds:sqlserver://" + ip + ";"
+ "databaseName=" + db + ";user=" + un + ";password="
+ password + ";";
conn = DriverManager.getConnection(ConnURL);
} catch (SQLException se) {
Log.e("ERRO0", se.getMessage());
} catch (ClassNotFoundException e) {
Log.e("ERRO1", e.getMessage());
} catch (Exception e) {
Log.e("ERRO2", e.getMessage());

I hope you can help. Thank you.

You have two records in table but you are using if(rs.next()) to fetch record which will return only single record.
Use for loop or while loop to get all records and iterate resultset in loop.

Data is not inserting into database of webhost from android

My data is not inserting to database of webhost.
Here is my ActionActivity.java from where I will send data to the database.
import android.app.Activity;

import android.widget.TextView;
import android.widget.Toast;
import java.io.InputStream;
public class ActionActivity extends Activity {
private String t;
TextView timer;
EditText e1,e2;
Button save;
static InputStream is = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_action);
Bundle time = getIntent().getExtras();
t = (String) time.get("com.example.masba.timemanagement.MESSAGE");
e1 = (EditText) findViewById(R.id.editText);
e1.setText(t, TextView.BufferType.EDITABLE);
e2 = (EditText) findViewById(R.id.editText2);
save = (Button) findViewById(R.id.save);
}
public void insert(View view){
String actionName = e1.getText().toString();
String time = e2.getText().toString();
Toast.makeText(this, "Data Inserting...", Toast.LENGTH_SHORT).show();
new SignupActivity(this).execute(actionName, time);
e1.setText("");
e2.setText("");
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;

#Override
public boolean onOptionsItemSelected(MenuItem item) {

int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
Now my SignupActivity.java Which extends Asynctask.
import android.content.Context;
import android.os.AsyncTask;
import android.widget.Toast;
import org.json.JSONException;
import org.json.JSONObject;
import java.io.BufferedReader;

}
protected void onPreExecute() {
}
#Override
protected String doInBackground(String... arg0) {
String actionName = arg0[0];
String time = arg0[1];
String link;
String data;
BufferedReader bufferedReader;
String result;
try {

link = "http://masumalmasba.comli.com/insertdata.php" + data;
URL url = new URL(link);

#Override

JSONObject jsonObj = new JSONObject(jsonStr);
String query_result = jsonObj.getString("query_result");
if (query_result.equals("SUCCESS")) {
Toast.makeText(context, "Data inserted successfully.", Toast.LENGTH_SHORT).show();

Toast.makeText(context, "Error parsing JSON data.", Toast.LENGTH_SHORT).show();
}
} else {
Toast.makeText(context, "Couldn't get any JSON data.", Toast.LENGTH_SHORT).show();
}
}
}
Now my insertdata.php code is:
<?php
$servername="mysql6.000webhost.com";
$username = "a1871724_masum";
$password = "almasba012";
$dbname = "a1871724_actiont";
$conn = new mysqli($servername , $username , $password , $dbname);
if($conn->connect_error)
{
die("Connection Failed: ".$conn->connect_error);
}
$action = $_GET['actionname'];
$time = $_GET['time'];
$sql = "INSERT INTO actiontime (name,time) VALUES ('($action)','($time)')";
if($conn->query($sql)===TRUE){
echo "New record created succesfully";
}
else{
echo "Error";
mysql_close($conn);
}
?>
