Attempt to invoke virtual method 'void androidx.recyclerview.widget.ItemTouchHelper.startDrag(androidx.recyclerview.widget.RecyclerView$ViewHolder)' on a null object reference
getting this error
I had a lot of database connection issues while trying out this project. After I started XAMMP (with Apache and MySQL only) and trying to run the application. The android part of the tutorial works but when I tried to connect my phone (as a test device) to the webserver hosted on my machine, it returns an error pertaining to "Unable to retrieve any data from server".
I tried browsing on http://localhost/test_android/index.php when it returned an error like:
Fatal error: Uncaught ArgumentCountError: mysqli_connect_errno() expects exactly 0 arguments, 1 given in D:\XAMPP\htdocs\test_android\db-connect.php:13 Stack trace: #0 D:\XAMPP\htdocs\test_android\db-connect.php(13): mysqli_connect_errno(Object(mysqli)) #1 D:\XAMPP\htdocs\test_android\user.php(12): DbConnect->__construct() #2 D:\XAMPP\htdocs\test_android\index.php(31): User->__construct() #3 {main} thrown in D:\XAMPP\htdocs\test_android\db-connect.php on line 13
I also checked the logcat logs of the app and it returned a similar error like the one on the top:
E/API123: 200
D/API123:
Fatal error: Uncaught ArgumentCountError: mysqli_connect_errno() expects exactly 0 arguments, 1 given in D:\XAMPP\htdocs\test_android\db-connect.php:13
Stack trace:
#0 D:\XAMPP\htdocs\test_android\db-connect.php(13): mysqli_connect_errno(Object(mysqli))
#1 D:\XAMPP\htdocs\test_android\user.php(12): DbConnect->__construct()
#2 D:\XAMPP\htdocs\test_android\index.php(31): User->__construct()
#3 {main}
thrown in D:\XAMPP\htdocs\test_android\db-connect.php on line 13
E/JSON Parser: Error parsing data org.json.JSONException: Value <br of type java.lang.String cannot be converted to JSONObject
I checked the questionable line and it looks like this:
Line 13: if (mysqli_connect_errno($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.

My issue org.apache error is coming no found
@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.
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!
