How to 'unlock' push to listen (acceptAndOpen)

Hi I have tried to find a way to do every morning and google on this topic without finding a good answer.

I have an application that continuously listening one pushes a bes server. Now, I need to change to listen pushes for a period of time. After this time, I have to stop listening (and treat the push messages but it's not the case.)

Set a time-out seems to work only when a connection is already open, so it's not help.

Finally, I tried to run a Thread just before the call to 'acceptAndOpen '. This Thread waits for a while and if nothing is received then it try to call to 'close' the connection, but all I get is a "Invalid PDAP queue state" in the Simulator. I provide the part of the code for more details.

StreamConnection stream = null;InputStream input = null;MDSPushInputStream pushInputStream = null;

[...]

while (!stop) {    try {    

        [...]

        synchronized (this) {

//                    scn = (StreamConnectionNotifier) Connector.open(URL + ";ConnectionTimeout=30000;deviceside=false",Connector.READ,true);            ConnectionFactory connFact = new ConnectionFactory();            ConnectionDescriptor connDesc = connFact.getConnection(URL + ";deviceside=false");            connFact.setConnectionTimeout(30000);            scn = (StreamConnectionNotifier) connDesc.getConnection();        }

        AccepConnectionTimeout thread = null;        while (!stop) {            try {                // NOTE: the following will block until data is received.                thread = new AccepConnectionTimeout(scn);                thread.start();                stream = scn.acceptAndOpen();            } catch (InterruptedIOException  iioe) {                Log.error(ERR_TAG + "Timeout waiting connection:" + iioe.getMessage());                scn.close();                scn = null;                // TODO do something here                continue;            }

            timestampUltimaRecepcion = System.currentTimeMillis();

[...]

public class AccepConnectionTimeout extends Thread {public boolean stop = false;public StreamConnectionNotifier scn = null;

public AccepConnectionTimeout(StreamConnectionNotifier scn) {    this.scn = scn;}

public void run() {    try {        Thread.sleep(30000);    } catch (Exception e) {        Log.error(ERR_TAG + "Error waiting for accept timeout");    }    if (!stop) {        try {            scn.close();        } catch (IOException ioe) {            Log.error(ERR_TAG + "Error closing connection after accept timeout:" + ioe.getMessage());        } catch (Exception e) {            Log.error(ERR_TAG + "(Exception)Error closing connection after accept timeout:" + e.getMessage());        }    }}

[...]

(NOTE: I only ran this in a simulator)

I can't find much information on this 'mistake' and also my main goal is to achieve the objective referred to in the second subparagraph. Could you help me somehow? How to do this? How to solve it? examples?

I'm not sure that understand your condition.

Normally what you would do if have an earpiece for push messages, and whenever a message is received, it starts a new Thread and pass the received data.  So I don't understand the problem with this:

"After this time I have to stop listening (and treat the push messages.

Adoption of the approach to treatment that I mentioned will ensure that pushed messages are processed as they are received, which seems the right thing to do.

As do you this, then I think that the obligation to stop the listener disappears.

Sorry I don't have any comment on your post, just this part of your application design.

    How would unlock my Firefox OS phone if it no longer meets the touch?

    On Android, you can connect a mouse: https://www.youtube.com/watch?v=TTW0yfol_kQ

    Hi Fekle,

    Unfortunately, it is not possible to connect a mouse to Firefox OS. You can write to our advocacy team to suggest new features and provide feedback on your use of Firefox OS:

    I also already asked B2G teams if it is possible to recover a phone without the password. The answer short, is that for security reasons, it is not possible.

    I hope you find this information useful. Please let us know if you have other questions about your Firefox OS device.
