在 native 层通过 pthread_create() 创建的线程，没有 attach 到 jvm，就没有对应的 java stacktrace。

java层创建的线程中执行native代码发生crash也无法获取到java堆栈

caikelun · 2019-06-13T07:23:15Z

目前输出的tombstone格式中，java stacktrace 是在dump文件的尾部，是否需要再确认下？
另外你可以直接用附带的 sample app 试一下。

子线程制造native crash

   new Thread(new Runnable() {
            @Override
            public void run() {
                XCrash.testNativeCrash(false);
            }
        }).start();

解析crash日志输出到logcat


    public static void log(String tag, String message) {
        int logLevel = Log.ERROR;
        // Split by line, then ensure each line can fit into Log's maximum length.
        for (int i = 0, length = message.length(); i < length; i++) {
            int newline = message.indexOf('\n', i);
            newline = newline != -1 ? newline : length;
            do {
                int end = Math.min(newline, i + 4000);
                Log.println(logLevel, tag, message.substring(i, end));
                i = end;
            } while (i < newline);
        }

感谢反馈！这里确实有问题，我马上修复。

lizhangqu · 2019-06-14T02:36:49Z

@caikelun

应该是这里的判断有问题

 if((is_main_thread && 0 == strcmp(c_name, "main")) ||
           (!is_main_thread && strstr(c_name, tname)))

strstr入参调换下顺序

 if((is_main_thread && 0 == strcmp(c_name, "main")) ||
           (!is_main_thread && strstr(tname, c_name)))
