App is crashing when i press on the register's button

Question

I've created an app that should use as registeration page for any user .(The details that the user need to provide is : Name,UserName,Password, and age). I think that everything is ok , so i cannot understand why when i press the send button that should communicate with my domain, the app is crashing . Maybe something wrong with the code?

Here is the JAVA CODE:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_register);

    final EditText etAge= (EditText) findViewById(R.id.etAge);
    final EditText etName= (EditText) findViewById(R.id.etName);
    final EditText etUsername= (EditText) findViewById(R.id.etUsername);
    final EditText etPassword= (EditText) findViewById(R.id.etPassword);
    final Button bRegister = (Button)findViewById(R.id.bRegister);

    bRegister.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            final String name=etName.getText().toString();
            final String username=etUsername.getText().toString();
            final String password=etPassword.getText().toString();
            final int age=Integer.parseInt(etAge.getText().toString());

            Response.Listener<String>responseListener= new Response.Listener<String>(){

                @Override
                public void onResponse(String response){
                    try {
                        JSONObject jsonResponse=new JSONObject(response);
                        boolean success=jsonResponse.getBoolean("success");

                        if(success){
                            Intent intent=new Intent(RegisterActivity.this, LoginActivity.class);
                            RegisterActivity.this.startActivity(intent);
                        }
                        else{
                            AlertDialog.Builder builder= new AlertDialog.Builder(RegisterActivity.this);
                            builder.setMessage("ההרשמה נכשלה .")
                           .setNegativeButton("נסה שוב",null)
                                    .setIcon(R.drawable.erroricon)
                                    .create()
                                    .show();
                        }
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            };
         RegisterRequest registerRequest= new RegisterRequest(name,username,age,password,responseListener);
            RequestQueue queue = Volley.newRequestQueue(RegisterActivity.this);
            queue.add(registerRequest);


        }
    });



}
}

And here is the crash details(Which i cannot understand anything from this)

EDIT 3
Here's what the app is saying as error when I'm trying to complete the reqisteration request:

 07-29 19:32:27.948 9882-10087/com.commandofox.loginrequest E/Volley: [246] BasicNetwork.performRequest: Unexpected response code 404 for http:/nittiest-jurisdicti.000webhostapp.com/register.php

as i was going to answer see the code below String name = ""; try { int f = Integer.parseInt(name); }catch (NumberFormatException e) { Log.e(TAG, "onCreate: Error"); } — Salman500, Jul 29 '17 at 20:08

Check your manifest, may be you did not add the INTERNET permission there.

Edit 1

After you posted logs, it becomes clearer - you tried to convert empty string ("" is a empty string of etAge editText) to int. It causes exception.

Watch at the following video: I learned from this video the coding for this stage and it looks like that Although my code is exactly like him, for some reason the app is working fine for him. – Toad32 Jul 29 '17 at 19:29
