PJSUA2 Android - Incoming calls drop after 32 seconds

I'm building a PJSUA2 (PJSIP 2.8) Android app and I have some issues: i.e. only on incoming call, call state remains in "PJSIP_INV_STATE_CONNECTING" and after 32 seconds the call drops.
I'm looking for the cause of the issue since several days, I googled a lot and all what I found is: in most situations this issue is related to NAT management or network issues related to NAT. In a few words: in most cases the called party does not receive the ACK after answering the call.
Finally I was able to log all SIP messages between my app and the SIP server and found that my app receives the ACK from the server, so I suppose it's not a network related issue.
I compiled PJSIP 2.8 with OpenSSL and SRTP support, but without video support (I don't need it at least at the moment). If it makes any difference, the app has a target version 28 and minimum SDK version 19.
I tried several apps on the market and they work fine enough with and without SRTP and with all signaling transports (UDP, TCP, TLS), WebRTC works fine too (tested with SipML5), so I would exclude a server misconfiguration. My app does the same (except SRTP with which I have some issues at the moment).
I tried with a SIP provider too (MessageNet) using UDP and the behaviour is always the same. I tried to use compact SIP messages and it behaves the same, with and without uri parameters, with and without STUN and or ICE and nothing changes. Mobile network and WiFi networks give the same results.
I tried to debug inside PJSIP library too, but without any success, then I tried to follow the code, to understand what I was doing wrong, but it doesn't seem to me there is something evidently wrong.
The following is the code (last version) which initializes PJSIP:

Finally, how I answer the code at the moment in a class which extends the PJSIP's Call class:
#Override
public void answerCall() {
Log.d(TAG, "Answering call...");
CallOpParam prm = new CallOpParam(true);
prm.setStatusCode(pjsip_status_code.PJSIP_SC_OK);
prm.getOpt().setAudioCount(1);
prm.getOpt().setVideoCount(0);
try {
this.answer(prm);
} catch (Exception e) {
e.printStackTrace();
}
}
I also tried with new CallOpParam(); with just the status code and nothing else, but nothing changes.
One note: I created the IdUri as sip:username#127.0.0.1 because without the host the resulting contact was and I thought that the missing user part may be the cause of the issue or part of it.
The following is the trace of the app <-> my Asterisk server communication during call (linked because of content length exceed).
https://gist.github.com/ivano85/a212ddc9a808f3cd991234725c2bdb45
The ServerIp is an internet public IP, while the MyIp[5.XXX.XXX.XXX] is my phone's public IP.
As you can see from the log, my app sends a 100 Trying, then a 180 Ringing when the phone rings, then the user answers and the app sends a 200 OK. The server replies with a ACK message (I would say it's not a NAT issue, because PJSIP receives the ACK). I see the same from Asterisk.
After this I would expect the call goes from PJSIP_INV_STATE_CONNECTING to PJSIP_INV_STATE_CONFIRMED, but it does not happen, so PJSIP continues to send a 200 OK and receive the ACK every about 2 seconds, until the call times out after 32 seconds and PJSIP disconnects the call (sending a BYE).
I'm starting to think that PJSIP just ignores ACK messages and just has a wrong behaviour. Please help me to understand what is happening here. I would appreciate it so much!
Obviously let me know if you think that more details are needed.

How to get Text response from DialogFlow agent in android?

How do I get this Default response in Android?
I want to get the same response as I get doing this CURL request in android. Is there a way to do this using API.AI SDK or otherwise?

You can use Dialogflow Android SDK. Check the documentation for integration and accessing the Dialogflow agent.
Get action
final Result result = response.getResult();
Log.i(TAG, "Action: " + result.getAction());
Get speech
final Result result = response.getResult();
final String speech = result.getFulfillment().getSpeech();
Log.i(TAG, "Speech: " + speech);
Get metadata
final Result result = response.getResult();
final Metadata metadata = result.getMetadata();
if (metadata != null) {
Log.i(TAG, "Intent id: " + metadata.getIntentId());
Log.i(TAG, "Intent name: " + metadata.getIntentName());
}
Get parameters
final Result result = response.getResult();
final HashMap<String, JsonElement> params = result.getParameters();
if (params != null && !params.isEmpty()) {
Log.i(TAG, "Parameters: ");
for (final Map.Entry<String, JsonElement> entry : params.entrySet()) {
Log.i(TAG, String.format("%s: %s", entry.getKey(), entry.getValue().toString()));
}
}

Intent failed with Canceled on SpeechFactory.fromSubscription (LUIS azure, android sdk)

I am getting the following message when trying to analyze an utterance with LUIS using the cognitive service android SDK:
Final result received: Intent failed with Canceled. Did you enter your Language Understanding subscription? WebSocket Upgrade failed with an authentication error (403). Please check the subscription key or the authorization token, and the region name., intent:
I am able to get an utterance evaluation via REST using the same Subscription key , and App ID passed to the SpeechFactory methods.
Moreover, continuous recognition through the Android SDK works as well.
Anyone is getting my same issue ?

stream screen to chromecast using Presentation

I'm using com.android.support:appcompat-v7:21.0.3 to develop an app that stream the screen to the TV using chromecast.
The problem is that when i retrieve the presentationDisplay it is null!
I'm using default receiver app and it seems that chromecast does not support
MediaControlIntent.CATEGORY_LIVE_VIDEO
This is the code:
private void updatePresentation() {
Log.d(TAG, "updatePresentation()");
MediaRouter.RouteInfo route = mMediaRouter.getSelectedRoute();
Display presentationDisplay = route != null ? route.getPresentationDisplay() : null;
Log.d(TAG, "MediaRouter.RouteIngo: " + route.getName());
if (presentationDisplay != null)
Log.d(TAG, "presentationDisplay " + presentationDisplay.getName());
else if (presentationDisplay == null)
Log.d(TAG, "presentationDisplay is null");
// Dismiss the current presentation if the display has changed.
if (mPresentation != null && mPresentation.getDisplay() != presentationDisplay) {
Log.i(TAG, "Dismissing presentation because the current route no longer "
+ "has a presentation display.");
mPresentation.dismiss();
mPresentation = null;
}
// Show a new presentation if needed.
if (mPresentation == null && presentationDisplay != null) {
Log.i(TAG, "Showing presentation on display: " + presentationDisplay);
mPresentation = new DemoPresentation(this, presentationDisplay);
mPresentation.setOnDismissListener(new DialogInterface.OnDismissListener() {
#Override
public void onDismiss(DialogInterface dialog)
{
if (mPresentation != null) mPresentation.dismiss();
}
});
try {
Log.d("mPresentation", "showing");
mPresentation.show();
} catch (WindowManager.InvalidDisplayException ex) {
Log.w(TAG, "Couldn't show presentation! Display was removed in "
+ "the meantime.", ex);
mPresentation = null;
}
}
}

on my own nexus 10 i used Chromecast App to setup the chromecast device and on my nexsus 4 all happened automatically.
No, I am not referring to just the Chromecast app.
Chromecast natively supports the Cast SDK and RemotePlaybackClient. It also supports serving as an external display, which can be used for Presentation. However, the user has to manually go into Settings > Displays > Cast Screen and choose the Chromecast. Then, you will get screen mirroring, and Presentation will work.

Connecting to existing Google Chromecast Session from Android (for generic remote control)

I am creating a generic Chromecast remote control app. Most of the guts of the app are already created and I've managed to get Chromecast volume control working (by connecting to a Chromecast device along side another app that is casting - YouTube for example).
What I've having difficult with is performing other media commands such as play, pause, seek, etc.
Use case example:
1. User opens YouTube on their android device and starts casting a video.
2. User opens my app and connects to the same Chromecast device.
3. Volume control from my app (works now)
4. Media control (play, pause, etc) (does not yet work)
I found the Cast api reference that explains that you can sendMessage(ApiClient, namespace, message) with media commands; however the "message" (JSON) requires the sessionId of the current application (Youtube in this case). I have tried the following, but the connection to the current application always fails; status.isSuccess() is always false:
Cast.CastApi
.joinApplication(mApiClient)
.setResultCallback(
new ResultCallback<Cast.ApplicationConnectionResult>() {
#Override
public void onResult(
Cast.ApplicationConnectionResult result) {
Status status = result.getStatus();
if (status.isSuccess()) {
ApplicationMetadata applicationMetadata = result
.getApplicationMetadata();
sessionId = result.getSessionId();
String applicationStatus = result
.getApplicationStatus();
boolean wasLaunched = result
.getWasLaunched();
Log.i(TAG,
"Joined Application with sessionId: "
+ sessionId
+ " Application Status: "
+ applicationStatus);
} else {
// teardown();
Log.e(TAG,
"Could not join application: "
+ status.toString());
}
}
});
Is is possible to get the sessionId of an already running cast application from a generic remote control app (like the one I am creating)? If so, am I right in my assumption that I can then perform media commands on the connected Chromecast device using something like this:
JSONObject message = new JSONObject();
message.put("mediaSessionId", sessionId);
message.put("requestId", 9999);
message.put("type", "PAUSE");
Cast.CastApi.sendMessage(mApiClient,
"urn:x-cast:com.google.cast.media", message.toString());
Update:
I have tried the recommendations provided by #Ali Naddaf but unfortunately they are not working. After creating mRemoteMediaPlayer in onCreate, I also do requestStatus(mApiClient) in the onConnected callback (in the ConnectionCallbacks). When I try to .play(mApiClient) I get an IllegalStateException stating that there is no current media session. Also, I tried doing joinApplication and in the callback performed result.getSessionId; which returns null.

A few comments and answers:
You can get the sessionId from the callback of launchApplication or joinApplication; in the "onResult(result)", you can get the sessionId from: result.getSessionId()
YouTube is still not on the official SDK so YMMV, for apps using official SDK, you should be able to use the above approach (most of it)
Why are you trying to set up a message yourself? Why not building a RemoteMediaPlayer and using play/pause that is provided there? Whenever you are working with the media playback through the official channel, always use the RemoteMediaPlayer (don't forget to call requestStatus() on it after creating it).

Yes it is possible , First you have to save sesionId and CastDevice device id
and when remove app from background and again open app please check is there sessionId then call bello line.
Cast.CastApi.joinApplication(apiClient, APP_ID,sid).setResultCallback(connectionResultCallback);
if you get success result then need to implement further process in connectionResultCallback listener.
