Firebase Android Method To Check Existence Of User's Profile Info In Firebase Database
I don't get any error message but I want to execute code differently. If you check following java code, it runs like Tag:1 > Tag:2 > Tag:4 > Tag:5 > Tag:3. I want to ru
Solution 1:
From what I can see from your code is:
- You already have the userID of the userProfile
- You are checking whether a profile exists on that specific id or no.
Well, creating an object and checking whether its null or no is definitely one way but Firebase has a pre-defined method for checking whether data exists on that specific node or no:
dataSnapshot.exists()
Returns true if this DataSnapshot contains any data. It is slightly more efficient than using snapshot.val() !== null.
This is what the official docs mention.
