I am trying to pull contacts from the phone of the user and then match these against the phone numbers I have in my parse backend and then display the matches in a custom list view. I have managed to do almost everything, however I am having trouble setting the global variable mBinderPhoneNumber correctly. For whatever reason according to logcat the variable is first showing as null and only later gets the correct value even though I am setting the variable correctly before I need to use it.
Here is the logcat which shows the variable is showing up as null at first and then only later getting set correctly:
12-31 15:17:12.242 27804-27935/com.rileymacdonaldapps.binder D/TAG: mBinderPhoneNumbers from AddContactsInList:null
12-31 15:17:12.902 27804-27804/com.rileymacdonaldapps.binder D/TAG: mBinderPhoneNumbers from onCreate: [CORRECT PARSE USER1, CORRECT PARSE USER2]
Can someone kindly help me out?
