My code is :
GcsFilename keyAsAFileName = new GcsFilename(contentBucketName, key);
GcsFileMetadata gcsFileMetadata = gcsService.getMetadata(keyAsAFileName);
ByteBuffer result = null;
if (gcsFileMetadata != null) {
result = ByteBuffer.allocate((int)gcsFileMetadata.getLength());
if(gcsFileMetadata.getLength()>0){
readChannel = gcsService.openReadChannel(keyAsAFileName, 0);
readChannel.read(result);
}
}
Please help.
