android的crash log

   在android下,如果我们写jni程序,可能经常会出现类似下面的crash log:

我们可以使用gdb来调试,但andorid下gdb不好用,而且不太稳定。其实可以直接通过上面的crash log知道调用堆栈的。

与调用堆栈相关的是类似下面的信息:

通过类似下面的命令就可以知道对应堆栈的源码信息了:

/home/xufan/android/android-1.5/prebuilt/linux-x86/toolchain/arm-eabi-4.2.1/bin/arm-eabi-addr2line -e /home/xufan/android/android-1.5/out/target/product/generic/symbols/system/lib/libxxxCamera.so 

000029fe  

红色部分需要按照crash log做修改。/home/xufan/android/android-1.5/为androoid代码的位置。
