Alsa configuration error on android device

[Vijay Pratap Singh <vijay.singh@xxxxxxxxxxx>]

Hi All,

We are trying to run PJSUA application on android device, for this we have cross-compiled(arm-linux-androideabi)  PJSIP.

We are trying to use alsa sound driver instead of openSLES with JNI frame-work.

Hence we have cross-compiled alsa for android and copied libasound.so.2.0.0  library on android device.

In config_site.h we did below changes:

//#define ANDROID 1
#define PJMEDIA_AUDIO_DEV_HAS_ALSA       1

When, we are running PJSUA app on android device, we suspect alsa has configuaration as  alsa is unable to open sound device.

Below is the complete log:

Please help me to resolve  this issue, also let me know-

Does PJSIP supports TINY-ALSA for android device?

Thanks a lot!
