EBADF (Bad file number) auf inputstream I/O

Habe ich diesen Fehler

java.io.IOException: Lesen fehlgeschlagen: EBADF (Bad file number)

auf dieser code-Zeile:

 while ((input = fis.read(buffer)) != -1) {

Was denken Sie, würde dies dazu führen, EBADF bad file number Fehler in dieser Zeile? Irgendwelche Ideen auf, wie man es beheben. Ich wollte nur einen funktionierenden stream zu Lesen in der PDF-Datei von der SD Lesen und setzen wieder auf die SD-Karte wieder mit einem anderen Namen.
