如何找到哪个方法导致NDK堆栈跟踪崩溃

Question

我的应用因.so文件而崩溃 我点了这个链接https://developer.android.com/ndk/guides/ndk-stack.html
使用上面的链接，我可以从log cat中获取堆栈跟踪转储 从堆栈跟踪中，它使用 ndk-stack工具向我显示所有函数名称。
但是我无法确定哪种方法确实导致我的应用程序崩溃？

这是我的应用程序中记录致命信号的日志。

id: 26940, tid: 27543, name: Thread-579  >>> com.nexge.nexgeotpdialer <<<
signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x34

它说明故障地址为0x34。但是使用ndk-stack工具它会显示所有带有功能名称的线程，但哪一个引起了崩溃？

Answer 1

我也在寻找跟踪SIGSEGV故障的方法。我决定做自己的踪迹。 https://github.com/claytonfan/trace 预期用途：

#include <stdio.h>
#include <stdlib.h>
#include <signal.h>
#include "trace.h

void sig_handler(int signo)
{
    if( signo ==  SIGSEGV ) {
        traceDump("Signal SIGSEGV");
    }
    // may handle other signo's
    exit( signo );
}

int main(int argc, char **argv)
{
    traceInit( "Prgram Test", &printf, 0 );
    signal( SIGSEGV, sig_handler );
    //
    // and possibly other signals
    //
    // . . . main() logic . . .
    return( 0 );
}

希望有所帮助。
