विकास पर्यावरण में सक्षम नहीं आवेदन जिसमें धागे मूल में लॉन्च किया जाएगा। मैंने धागे में एक ब्रेक प्वाइंट पकड़ा। (जब मैंने गैलेक्सी एस 2 पर कोशिश की तो मुझे एक त्रुटि मिल रही थी, "इस प्लेटफॉर्म में थ्रेड डीबगिंग समर्थित नहीं है"। इसलिए मैंने एवीडी 2.3.3 लेवल 10 बनाया)।एंड्रॉयड में NDK-gdb में तोड़ बिंदु हिट करने के लिए
इस के बाद मैं इस
#0 0xafd0c51c in epoll_wait() from /Volumes/SecureCode/webos/rta/android/obj/local/armeabi/libc.so
#1 0xa81216a6 in ??()
की तरह एक त्रुटि हो रही थी मैं googled और इस Solution (Link Here).
पाया मैं वहाँ
$ adb pull /system/lib lib
$ ndk-gdb
...
(gdb) set solib-search-path lib
संबंधी दिशा-निर्देश का पालन किया लेकिन इस के बाद भी मैं नहीं कर रहा हूँ ब्रेक पॉइंट हिट करने में सक्षम। मैं अभी भी इस poll_wait() पर अटक गया हूं और आगे नहीं बढ़ रहा हूं।

मुख्य भाग पर ध्यान केंद्रित करना चाहते हैं। यह सापेक्ष पता (रनटाइम पता) पर विचार नहीं कर रहा है, इसलिए ब्रेक पॉइंट को हिट करने में सक्षम नहीं है। और यह epoll_wait() पर अटक गया, आगे नहीं बढ़ रहा है।
क्या कोई मेरी मदद करेगा कृपया आगे कैसे आगे बढ़ सकता है?
धन्यवाद & सादर,
