Hi,
Sorry for long post, but it cannot be shorter.
I have huge problem with deinit endpoint during call. I'm using latest
version of pjsip (2.6) build stack with ndk 11. When I call
Endpoint.delete() or Endpoint.libDestroy() I get crash from lib.

My problem is connected with gc
(http://www.pjsip.org/docs/book-latest/html/intro_pjsua2.html#problems-with-garbage-collection)\

Do you know what kind of objects I need to delete before I want to
deinitialize lib?

I want to do that when I lost connection, when I go out from WiFi or
other user interaction with WiFi.

In these case I get two kinds of error:

1. "conf && port < conf->max_ports" failed (log in attachment)
2. "Calling pjlib from unknown/external thread." (log in attachment)

I also attach full log when I disconnect WiFi during call. As you can
see. I try disconnect audio ports but it doesn't help.

BR, Andrzej

Here is my deinit procedure:
void deInitialize(final SipService sipService)
{
Log.d(this, "deInitialize deleteAudioMedia();");
deleteAudioMedia();
Log.d(this, "deInitialize deleteCall();");
deleteCall(sipService);
Log.d(this, "deInitialize deleteAccount();");
deleteAccount();
try
{
IntVector transportVector = ep.transportEnum();
for (int i = 0; i < transportVector.size(); i++)
{
Log.d(this, "deInitialize transportClose();");
ep.transportClose(i);
}
}
catch (Exception e)
{
Log.e(this, e);
}
Log.d(this, "deInitialize sipTpConfig.delete();");
sipTpConfig.delete();
sipTpConfig = null;
try
{
Thread.sleep(3000);
Log.d(this, "deInitialize ep.libDestroy();");
ep.libDestroy();
}
catch (Exception e)
{
Log.e(this, e);
}
Log.d(this, "deInitialize ep.delete();");
ep.delete();
ep = null;
sipService.notifyStackState(pjsua_state.PJSUA_STATE_NULL);
}

void deleteCall(final SipService sipService)
 {
     try
     {
         ep.hangupAllCalls();
         if (mSipAccount != null)
         {
             Stream.of(mSipAccount.getCallIDs()).filter(callId -> 

callId != -1).forEach(callId -> {
SipCall call = mSipAccount.getCall(callId);
if (call != null)
{
call.delete();
call = null;
}
sipService.notifyCallDisconnected(callId);
});
}
}
catch (Exception e)
{
Log.d(this, "deleteCall", e);
}
}

 void deleteAudioMedia()
 {
     try
     {
         AudioMediaVector audioMediaVector = ep.mediaEnumPorts();
         for (int i = 0; i < audioMediaVector.size(); i++)
         {
             Log.d(this, "audioMedia deleted");
             AudioMedia audioMedia = audioMediaVector.get(i);
             ep.mediaRemove(audioMedia);
             audioMedia.delete();
         }
         Log.d(this, "audDevManager deleted");
         ep.audDevManager().delete();
     }
     catch (Exception e)
     {
         Log.e(this, "deleteAudioMedia", e);
     }
 }

void deleteAccount()
 {
     if (mSipAccount != null)
     {
         try
         {
             mSipAccount.delete();
         }
         catch (final Exception e)
         {
             Log.e(this, e);
         }
     }
     mSipAccount = null;
 }

where

ep - Endpoint
mSipAccount - public class SipAccount extends Account

// try to force GC to do its job before destroying the library, since it's
// recommended to do that by PJSUA examples
        Runtime.getRuntime().gc();
Thread.sleep(100);
