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.content.Context;
import android.provider.Settings;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
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) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
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;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLEncoder;
public class SignupActivity extends AsyncTask<String, Void, String> {
private Context context;
public SignupActivity(Context context) {
this.context = context;
}
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 {
data = "?actioname=" + URLEncoder.encode(actionName, "UTF-8");
data += "&time=" + URLEncoder.encode(time, "UTF-8");
link = "http://masumalmasba.comli.com/insertdata.php" + data;
URL url = new URL(link);
HttpURLConnection con = (HttpURLConnection) url.openConnection();
bufferedReader = new BufferedReader(new InputStreamReader(con.getInputStream()));
result = bufferedReader.readLine();
return result;
} catch (Exception e) {
return new String("Exception: " + e.getMessage());
}
}
#Override
protected void onPostExecute(String result) {
String jsonStr = result;
if (jsonStr != null) {
try {
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();
} else if (query_result.equals("FAILURE")) {
Toast.makeText(context, "Data could not be inserted.", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(context, "Couldn't connect to remote database.", Toast.LENGTH_SHORT).show();
}
} catch (JSONException e) {
e.printStackTrace();
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);
}
?>

Make a string from a View element

I have two seekbars in my main activity but I can only use one of them at a time, so I need to retrieve a value seekbarx and seekbary, store either of them in a string variable to use it forward. I already used onProgressChange and onStopTrackingTouch but I guess it doesn't hold the value long enough.
This is what I had for the seekbars

It prints in the LogCat touching Y bar. servo = servoy/ but when I want to use the servo value it prints null.
How can I hold the value for this string?

AsyncTask unfortunately stops on second execution

I'm trying to get strings from my Arduino with my Android phone, everything goes well except for when I press my updatebutton the second time, it unfortunately stops.
I can't seem to track the problem and I ran out of options so I'm asking for help to you guys now.

and if there's a better way of getting strings from arduino please help out.

You probably need to close dtSocket at the end of doInBackground(). Otherwise you will try to create a socket on a bound port when you execute it the second time.

Server can read from android phone also the android client get message from server.
The Problem is whenever The Server detects connection and start Receives text and Sends Reply . The code doesnt accept more connection after that .
Note:
I tried to to test using C# client it works fine so i got a problem on the client side

You can't use more then AsyncTask.
The simplest approach is to move the code inside doInBackground() to a Runnable and then start a new Thread with that runnable on every click.
Example:
private Runnable rSocketCore = new Runnable() {
public void run() {
//here goes your connection code
}
};
b.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
new Thread(rSocketCore).start();
}
Note: You will also need an Handler if you want to communicate from the thread to the UI.
Regards.

Which cursor are you talking about?
If it's when you click on an item it's because you assign the cursor q null in onCreate and then call moveToPosition on it in onListItemClick.
