Use transferobserver Android to set permissions for AWS objects

private void beginUpload(String filePath) {
        if (filePath == null) {
            Toast.makeText(this, "Could not find the filepath of the selected file", Toast.LENGTH_LONG).show();
            return;
        }

        File file = new File(filePath);
        TransferObserver observer = transferUtility.upload(Constants.BUCKET_NAME, file.getName(), file);
        observers.add(observer);
        HashMap<String, Object> map = new HashMap<String, Object>();
         Util.fillMap(map, observer, false);
        transferRecordMaps.add(map);
        observer.setTransferListener(new UploadListener());
        simpleAdapter.notifyDataSetChanged();
    }

resolvent:

Use putobjectrequest to set permissions on the current bucket and file (such as this)

if(this.publicRead)
{
    por.setCannedAcl(CannedAccessControlList.PublicRead);
}
