getting this error

I noticed that when importing your project there will an error when trying to build it using gradle 2.4. I am using latest Android Studio & unfortunately your project cannot be build.

For example using this project https://www.journaldev.com/10024/android-recyclerview-android-cardview-example-tutorial .

Hey there!

I belong to an open source security research community, and a member (@ready-research) has found an issue, but doesn’t know the best way to disclose it.

If not a hassle, might you kindly add a SECURITY.md file with an email, or another contact method? GitHub recommends this best practice to ensure security issues are responsibly disclosed, and it would serve as a simple instruction for security researchers in the future.

Thank you for your consideration, and I look forward to hearing from you!

I had a lot of database connection issues while trying out this project. After I started XAMMP (with Apache and MySQL only) and trying to run the application. The android part of the tutorial works but when I tried to connect my phone (as a test device) to the webserver hosted on my machine, it returns an error pertaining to "Unable to retrieve any data from server".

I tried browsing on http://localhost/test_android/index.php when it returned an error like:
Fatal error: Uncaught ArgumentCountError: mysqli_connect_errno() expects exactly 0 arguments, 1 given in D:\XAMPP\htdocs\test_android\db-connect.php:13 Stack trace: #0 D:\XAMPP\htdocs\test_android\db-connect.php(13): mysqli_connect_errno(Object(mysqli)) #1 D:\XAMPP\htdocs\test_android\user.php(12): DbConnect->__construct() #2 D:\XAMPP\htdocs\test_android\index.php(31): User->__construct() #3 {main} thrown in D:\XAMPP\htdocs\test_android\db-connect.php on line 13

I also checked the logcat logs of the app and it returned a similar error like the one on the top:
E/API123: 200
D/API123:

Fatal error: Uncaught ArgumentCountError: mysqli_connect_errno() expects exactly 0 arguments, 1 given in D:\XAMPP\htdocs\test_android\db-connect.php:13
Stack trace:

#2 D:\XAMPP\htdocs\test_android\index.php(31): User->__construct()
#3 {main}
thrown in D:\XAMPP\htdocs\test_android\db-connect.php on line 13

E/JSON Parser: Error parsing data org.json.JSONException: Value <br of type java.lang.String cannot be converted to JSONObject

I checked the questionable line and it looks like this:
Line 13: if (mysqli_connect_errno($this->connect)){
Line 14: echo "Unable to connect to MySQL Database: " . mysqli_connect_error();
Line 15: }

I used the default credentials on XAMMP with the DB_HOST set as localhost.

two time callback return

Hello I'm new to programming and not sure how to change the spinner from the AndroidRoomTodo project. How to change the categories String[] to an edittext. could you help me out? Thank you

@journaldev I need the callback when I will drop the raw on a specific position, yes we are getting the callback for row moved using public void onRowMoved(int fromPosition, int toPosition).
But I need to call the API when I have completed my dragging from one position to another to notify the server, if I will call the API every time when moving then this will creates too many counts for the API calls.

Please let me know if there is a possible solution for this.
