I am running into an issue where I get the error.
Process: ericscalise.cs499.bloodhoundcommunity, PID: 22247 java.lang.RuntimeException: Unable to start activity ComponentInfo{ericscalise.cs499.bloodhoundcommunity/ericscalise.cs499.bloodhoundcommunity.MyProfileActivity}: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.view.View.setOnClickListener(android.view.View$OnClickListener)' on a null object reference
I am not sure 100% what I am doing wrong. This section is to show my users firebase information back to them and I have the firebase setting all set correctly according to their docs and android studio. Below is the code from the activity that is throwing the error. and help would be appreciated.
