Issue Sending data to mysql in android studio

I am currently building an app for my university project and I am well and truly stuck. I am currently trying to send data from my apps sign up page to my Mysql database, I have gotten as far as being able to connect due to error logs showing that a connection was successful but no data is being sent to the database?
I have tried multiple ways of sending the data through php but it doesn't seem to make any difference. I was hoping maybe someone could point out my mistake and help me get past this hurdle I have been stuck on for so long.

This is the result when running my app:
Error Occured org.json.JSONException: No value for Success
Edit
After adding error_reporting(E_ALL); to both php scripts, I am confident that the error does not lie with the php code as no error is being reported. {"success":1,"message":"Successfully uploaded"} This is the response from my php code so I am connecting to the database successfully but I am unsure what the issue is with my android studio code.

Your code is almost fine. You just missed one thing. You did not initialize VolleyRequest. Inside simponData and UpdateData methods write this line at the bottom.
RequestQueue requestQueue = Volley.newRequestQueue(getContext());
requestQueue.add(my_request);
instead of AppController.getInstance().addToRequestQueue(updateReq).
other thing is you are calling the fragment in intent from when response is received .You should call onbackPress() when result is recieved successfully.
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
pd.cancel();
try {
JSONObject res = new JSONObject(response);
Toast.makeText(InsertKategori.this, ""+ res.getString("message") , Toast.LENGTH_SHORT).show();
} catch (JSONException e) {
e.printStackTrace();
}
onBackPressed();
}
},
It will restore the previous fragment. In order to update the KategoriFragment view when successful response is received, you can call the getData() method in onResume() method instead of oncreate(). it will call this method whenever fragment is visible to the use

i used spinner and select value and submit it but no error with submission description in database. i am using oracle web services with wamp server, but description submitting spinner value is not.
thanks in advance

use staticSpinner.getSelectedItem().toString() instead of staticSpinner.toString() in posting parameters
you are posting wrong data check below code
insert.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String DESCR = Descr.getText().toString();
final String Spin = staticSpinner.getSelectedItem().toString();
StringRequest request = new StringRequest(Request.Method.POST, insertUrl, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
if(Descr.getText().toString().equals("")){
Toast.makeText(getApplication(),"Please Enter Detail ",Toast.LENGTH_LONG).show();
}
else if(Descr.getText().toString().length()<10){
Toast.makeText(getApplication(),"Text Must be Greater Than 10",Toast.LENGTH_LONG).show();
}
else{
System.out.println(response.toString());
Toast.makeText(getApplication(),"Application Submitted Successfully....!",Toast.LENGTH_LONG).show();
Intent intent = new Intent(atd_leave_form. this, Issue.class);
