I try to log in when clicking the button. I can see from the log that I have entered the correct entries. But it stays in this activity.
Here is the LoginActivity.java(When i press login, i get toast message: STAP 3):
public class LoginActivity extends Activity {
Button btnLogin;
Button btnLinkToRegister;
EditText inputEmail;
EditText inputPassword;
TextView loginErrorMsg;
// 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_UID = "uid";
private static String KEY_NAME = "name";
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.login);
// Importing all assets like buttons, text fields
inputEmail = (EditText) findViewById(R.id.loginEmail);
inputPassword = (EditText) findViewById(R.id.loginPassword);
btnLogin = (Button) findViewById(R.id.btnLogin);
btnLinkToRegister = (Button) findViewById(R.id.btnLinkToRegisterScreen);
loginErrorMsg = (TextView) findViewById(R.id.login_error);
// Login button Click Event
btnLogin.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
String email = inputEmail.getText().toString();
String password = inputPassword.getText().toString();
UserFunctions userFunction = new UserFunctions();
Log.i("Button", "Login");
JSONObject json = userFunction.loginUser(email, password);
// check for login response
try {
if (json != null && json.getString(KEY_SUCCESS) != null) {
Toast.makeText(getApplicationContext(),
"STAP 1", Toast.LENGTH_LONG).show();
loginErrorMsg.setText("");
String res = json.getString(KEY_SUCCESS);
if(Integer.parseInt(res) == 1){
// user successfully logged in
// 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_NAME), json_user.getString(KEY_EMAIL), json.getString(KEY_UID), json_user.getString(KEY_CREATED_AT));
// Launch Dashboard Screen
Intent myactivity = new Intent(getApplicationContext(), MyActivity.class);
// Close all views before launching Dashboard
myactivity.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(myactivity);
Toast.makeText(getApplicationContext(),
"STAP 2", Toast.LENGTH_LONG).show();
// Close Login Screen
finish();
}else{
Toast.makeText(getApplicationContext(),
"Error logging innnn!", Toast.LENGTH_LONG).show();
// Error in login
loginErrorMsg.setText("Incorrect username/password");
}
}
} catch (JSONException e) {
Toast.makeText(getApplicationContext(),
"STAP 3", Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
});
// Link to Register Screen
btnLinkToRegister.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent i = new Intent(getApplicationContext(),
RegisterActivity.class);
startActivity(i);
finish();
}
});
}
}
Here is the UserFunctions.java:
public class UserFunctions {

private static String login_tag = "login";
private static String register_tag = "register";

I ran this code locally on a phpmyadmin, it worked. I swapped to the database in the cloud and it does not work anymore... Any help is welcome as I am wasting my time for hours now....
To make it a bit more clear: It does not access the if statement within try{}
