Can't pass null for argument 'pathString' in child in Firebase Database
Hi Hello Friends
Today Video Topic about
"Can't pass null for argument 'pathString' in child() in Firebase Database"
Why This Problem :
Any null child Pass to Database then Will face the Error
DatabaseReference refAvailable = FirebaseDatabase.getInstance().getReference("Driver_Available").child(servicecategory);
This Variable presend null Values
String servicecategory;
So i'm changed Empty Value
String servicecategory = "" ;
From My side i'm clear issue
Then you face this Error Check First passing Child Value Null or not
