My Database Image

enter image description here

Varieties Details

 refDatabase = FirebaseDatabase.getInstance().getReference().child("INT").child("varieties");
    refDatabase.keepSynced(true);


    refDatabase.getRef().addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {
            Log.d(TAG,""+dataSnapshot.toString());
        }

        @Override
        public void onCancelled(DatabaseError databaseError) {
            Log.d(TAG,databaseError.getMessage());
        }
    });

As "image" data contains the Base64 encoded image.

As the error message says, you're retrieving more data than can be expanded in your phone's memory. There are 2 ways for solving that.

  1. To free your phone's memory to hold more data.
  2. To filter data using one of the filtering methods.

Please see the offical documentation regarding filtering data within Firebase.
