[pjmedia] Unable to find default audio device on Android

Hi R?gis,

First of all thanks for your quickly reply. I'm building the library from
CSipSimple project as you say I use pjsip_android subfolder.

I try to compile with 2.3 compatibility instead 1.5 but I get the same error
code (420006). I can't use CSipSimple directly because I don't use sip part,
so I make some native functions in c that do the hard work.

Do you have any idea about I'm doing bad?

I paste my Application.mk below:

APP_PROJECT_PATH := $(call my-dir)/../../../CSipSimple
#APP_PROJECT_PATH := $(call my-dir)/project
APP_BUILD_SCRIPT= := $(call my-dir)/project/build/Android.mk
#APP_OPTIM        := debug
APP_OPTIM        := release
APP_ABI := armeabi armeabi-v7a
#APP_ABI := armeabi-v7a
#APP_ABI := armv4t
APP_STL := stlport_static


MY_USE_G729 := 1
MY_USE_ILBC := 0
MY_USE_G722 := 1
MY_USE_G7221 := 0
MY_USE_SPEEX := 1
MY_USE_GSM := 1
MY_USE_SILK := 1
MY_USE_CODEC2 := 0
MY_USE_TLS := 0
MY_USE_WEBRTC := 0

MY_ANDROID_DEV := 2

BASE_PJSIP_FLAGS := -DPJ_ANDROID=1 -DPJMEDIA_HAS_G729_CODEC=$(MY_USE_G729) \
    -DPJMEDIA_HAS_ILBC_CODEC=$(MY_USE_ILBC)
-DPJMEDIA_HAS_G722_CODEC=$(MY_USE_G722) \
    -DPJMEDIA_HAS_SPEEX_CODEC=$(MY_USE_SPEEX)
-DPJMEDIA_HAS_GSM_CODEC=$(MY_USE_GSM) \
    -DPJMEDIA_HAS_SILK_CODEC=$(MY_USE_SILK)
-DPJMEDIA_HAS_CODEC2_CODEC=$(MY_USE_CODEC2) \
    -DPJMEDIA_HAS_G7221_CODEC=$(MY_USE_G7221)
-DPJMEDIA_HAS_WEBRTC_CODEC=$(MY_USE_WEBRTC) \
    -DPJ_HAS_SSL_SOCK=$(MY_USE_TLS) -DPJMEDIA_HAS_ZRTP=$(MY_USE_TLS) \
    -DPJ_ANDROID_DEVICE=$(MY_ANDROID_DEV)

I don't use Webrtc so I desactivated it.

You said "pjsip_android sub project also includes other specific glues for
android." What are this includes? And where I can find this file?

Many thanks!

BR,
Isidoro.
