Is there a way to debug this using the ndk debugger in Android? I tried this series of calls to detect the new ip address after switching between wifi and 3g: pj_str_t new_contact; new_contact = pjsua_var.acc[2].contact; __android_log_print(ANDROID_LOG_DEBUG, "main_android", "current contact %s", new_contact); pjsua_detect_nat_type(); after switch the "pjsua_detect_nat_type()" causes a fatal signal 11, which I have come to find just means crashing. When I try to run ndk-gdb from the project directory per the directions: /pjsip-android/pjsip-apps/src/apjsua, I get: ndk-gdb /android-ndk-r8//build/core/add-application.mk:133: *** Android NDK: Aborting... . Stop. ERROR: The device does not support the application's targetted CPU ABIs! Device supports: armeabi-v7a armeabi Package supports: Android NDK: Your APP_BUILD_SCRIPT points to an unknown file: ./jni/Android.mk any help on either issue would be great, thanks!
