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: snd_config_search_definition() : error = No such file or directory snd_config_search_definition() : key = defaults.pcm.subdevice snd_config_search_definition() : key = refer
