If a Manager is strong referenced from a gc root, usually the instances
map, it should not hold itself a strong reference the connection in
order to avoid a cycle that prevents the Connection instance from being
gc'ed.
SMACK-383
This patch provides three components required to implement XEP-0184:
* DeliveryReceiptRequest is a PacketExtension to request a receipt
* DeliveryReceipt is a PacketExtension that contains the receipt
* DeliveryReceiptManager to handle sending/receiving of requests and
receipts.
Implementation:
For requesting a receipt, just add a new DeliveryReceiptRequest() to
your message or use the helper function:
DeliveryReceiptManager.addDeliveryReceiptRequest(packet);
Register a ReceiptReceivedListener to find out if your packet arrived:
DeliveryReceiptManager.getInstanceFor(myConnection)
.registerReceiptReceivedListener(new ReceiptReceivedListener() {
@Override public void onReceiptReceived(String fromJid,
String toJid, String receiptId) {
// receipt received for packet id receiptId
}
To answer a receipt request, you can either check incoming packets
manually:
if (DeliveryReceiptManager.hasDeliveryReceiptRequest(packet)) {
// send receipt
}
Or you can enable automatic receipt transmission with:
DeliveryReceiptManager.getInstanceFor(myConnection)
.setAutoReceiptsEnabled(true);
