'PostFragment'の102行は何ですか？ – BlackHatSamurai
これです：StorageReference storageReference = FirebaseStorage.getInstance（） .getReference（mmPost.getPostImageUrl（））; （新しいFirebaseImageLoader（）） Glide.with（getActivity（）） @BlackHatSamurai – Dskato
@BlackHatSamurai私はこれを試してみますが、私は新しい例外があります：} java.lang.IllegalArgumentException：完全なURLであってはなりません。 – Dskato
