read failed: EBADF (Bad file number)

问题:

When I try do a copy one file of the external storage for into folder database, this error happens:

java.io.IOException: read failed: EBADF (Bad file number)

This error happens on the line of while of this method

private void copiarBaseDados(InputStream input) throws IOException{   OutputStream output = new FileOutputStream(ConfiguracoesBaseDados.BANCO_PATH + ConfiguracoesBaseDados.BANCO_NOME);   int tamanho;   byte[] buffer = new byte[1024];   while ((tamanho = input.read(buffer)) > 0)         output.write(buffer, 0, tamanho);   output.flush();   output.close();   input.close(); }

Any idea what could be the problem? Thanks
