SkImageDecoder: Fabrik zurückgegeben Null

Question

Ich benutze einen MySQL-Server, um Bilder von der Datenbank zu Android zu holen, um in einem ImageView anzuzeigen. Allerdings erhalte ich folgende Fehlermeldung:

SkImageDecoder:: Factory returned null 

Dies vor beantwortet wurde, aber ich nenne .decodeStream einmal? Es wäre dankbar, wenn Sie mir

Logcat helfen könnte:
