I am new to Android programming and I am trying to create a register and login function with php, mysql and sqlite. I am having this error after I clicked the register or login button. How do I fix this?

I am not sure which class is causing the error. This is the Register class:
public class Register extends Activity {
Button btnRegister, btnLinkToLogin;
EditText inputEmail;
EditText inputPassword, inputCPassword;
EditText inputContact;
TextView registerErrorMsg;
// JSON Response node names
private static String KEY_SUCCESS = "success";
private static String KEY_ERROR = "error";
private static String KEY_ERROR_MSG = "error_msg";
private static String KEY_CONTACT = "contact";
private static String KEY_EMAIL = "email";
private static String KEY_CREATED_AT = "created_at";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
// Importing all assets like buttons, text fields
inputEmail = (EditText) findViewById(R.id.registerEmail);
inputPassword = (EditText) findViewById(R.id.registerPassword);
inputCPassword = (EditText) findViewById(R.id.confirmPassword);
inputContact = (EditText) findViewById(R.id.registerContact);
btnRegister = (Button) findViewById(R.id.btnRegister);
btnLinkToLogin = (Button) findViewById(R.id.btnLinkToLogin);
registerErrorMsg = (TextView) findViewById(R.id.register_error);
// Register Button Click event
btnRegister.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
String password = inputPassword.getText().toString();
String confirmpass = inputCPassword.getText().toString();
//Check all fields
if(inputContact.length()<10)
{
Toast.makeText(Register.this,"Please Enter correct mobile number", Toast.LENGTH_LONG).show();
return;
}
if(inputPassword.length()<6)
{
Toast.makeText(Register.this,"Please Enter minimum 6 characters in password", Toast.LENGTH_LONG).show();
return;
}
if(!password.equals(confirmpass))
{
Toast.makeText(Register.this,"Password does not match", Toast.LENGTH_LONG).show();
return;
}
if(inputEmail.length()<6)
{
Toast.makeText(Register.this,"Please Enter valid email", Toast.LENGTH_LONG).show();
return;
}
String contact = inputContact.getText().toString();
String email = inputEmail.getText().toString();
//String password = inputPassword.getText().toString();
UserFunctions userFunction = new UserFunctions();
JSONObject json = userFunction.registerUser(email,contact,password);
// check for login response
try {
if (json.getString(KEY_SUCCESS) != null) {
registerErrorMsg.setText("");
String res = json.getString(KEY_SUCCESS);
if(Integer.parseInt(res) == 1){
// user successfully registred
// Store user details in SQLite Database
DatabaseHandler db = new DatabaseHandler(getApplicationContext());
JSONObject json_user = json.getJSONObject("user");
// Clear all previous data in database
userFunction.logoutUser(getApplicationContext());
db.addUser(json_user.getString(KEY_EMAIL), json_user.getString(KEY_CONTACT), json_user.getString(KEY_CREATED_AT));
// Launch Dashboard Screen
Intent dashboard = new Intent(getApplicationContext(), MainMenu.class);
// Close all views before launching Dashboard
dashboard.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(dashboard);
// Close Registration Screen
finish();
}else{
// Error in registration
registerErrorMsg.setText("Error occured in registration");
}
}
} catch (JSONException e) {
e.printStackTrace();
}
}
});
// Link to Login Screen
/* public void btnLinkToLogin(View view) {
Intent i = new Intent (this, LoginActivity.class);
startActivity (i);
finish();
}*/
btnLinkToLogin.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent i = new Intent(getApplicationContext(),LoginActivity.class);
startActivity(i);
// Close Registration View
finish();
}
});
}}
This is UserFunctions class:
public class UserFunctions {
private JSONParser jsonParser;
private static String loginURL = "http://10.0.2.2/project/index.php";
private static String registerURL = "http://10.0.2.2/project/index.php";
private static String login_tag = "login";
private static String register_tag = "register";
// constructor
public UserFunctions(){
jsonParser = new JSONParser();
}
/**
* function make Login Request
* @param email
* @param password
* */
public JSONObject loginUser(String email, String password){
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("tag", login_tag));
params.add(new BasicNameValuePair("email", email));
params.add(new BasicNameValuePair("password", password));
JSONObject json = jsonParser.getJSONFromUrl(loginURL, params);
// return json
// Log.e("JSON", json.toString());
return json;
}
/**
* function make Login Request
* @param name
* @param email
* @param password
* */
public JSONObject registerUser(String email, String contact, String password){
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("tag", register_tag));
params.add(new BasicNameValuePair("email", email));
params.add(new BasicNameValuePair("contact", contact));
params.add(new BasicNameValuePair("password", password));
// getting JSON Object
JSONObject json = jsonParser.getJSONFromUrl(registerURL, params);
// return json
return json;
}
/**
* Function get Login status
* */
public boolean isUserLoggedIn(Context context){
DatabaseHandler db = new DatabaseHandler(context);
int count = db.getRowCount();
if(count > 0){
// user logged in
return true;
}
return false;
}
/**
* Function to logout user
* Reset Database
* */
public boolean logoutUser(Context context){
DatabaseHandler db = new DatabaseHandler(context);
db.resetTables();
return true;
}}
