Can someone help me about this error? " java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.String.equals(java.lang.Object)' on a null object reference"
and it keeps saying my error is around this line -->
if (searchRiderMowdel.getusername().equals(textViewValue))
and I tried some methods and it keeps crashing as usual
