Hello folks,
I'm trying to create multiple TCP listeners in pjsua2 on android using the pjproject-2.5.5 release. Thing is, I don't really require many of them, i just need to replace the current one with a new instance because Doze mode is messing things up.
After returning from Doze mode, I cannot create more TCP listeners and thus cannot (re)register anymore, here's the error I'm getting in Java:
D/PJSIP: 15:20:41.303 tcptp:47899 SIP TCP transport destroyed

Description: Object with the same type exists (PJSIP_ETYPEEXISTS)

So i've grepped for PJSIP_ETYPEEXISTS and found occurances in pjsip/src/pjsip/sip_transport.c and made a small patch in this fashoin:
PJ_DEF(pj_status_t) pjsip_tpmgr_register_tpfactory( pjsip_tpmgr *mgr,
pjsip_tpfactory *tpf)
{
pjsip_tpfactory *p;
pj_status_t status;
pj_lock_acquire(mgr->lock);
/* Check that no factory with the same type has been registered. */
status = PJ_SUCCESS;
for (p=mgr->factory_list.next; p!=&mgr->factory_list; p=p->next) {
if (p->type == tpf->type) {
/*
* SHARK
* attempted fix; if a type exists, simply
* overwrite it instead of telling me it already exists
* status = PJSIP_ETYPEEXISTS;
* break;
*/
pj_list_insert_after(p, tpf);
pj_list_erase(&p);
pj_lock_release(mgr->lock);
return status;
}
//rest of the function ommited
However, I'm still facing the PJSIP_ETYPEEXISTS error and am somewhat clueless as to where it's coming from as if the patch didn't have any effect which leads me to believe i patched the wrong file or in the wrong place
I have also read the archives about a similar-ish problem in a thread called "Multiple endpoints" in which a one-liner patch was attached by Alain Totouom which i cannot find...
Would someone be able to nudge me in the right direction with this issue?
Kind regards, happy new year and merry christmass holidays,
Aleksandar
