高通android q 通过backtrace，使用addr2ine工具，定位crash问题记录

crash日志记录如下：

1.找到带有符号表的相应的库文件或者可执行文件：

        高通sda660为例，我这里目录是 android/out/target/product/sdm660_64/symbols/vendor/lib，

定位  audio.primary.sdm660.so 这个库，此时异常pc  00042c98

执行：addr2line -e audio.primary.sdm660.so -f 00042c98

则会有如下输出：

in_read
vendor/qcom/opensource/audio-hal/primary-hal/hal/audio_hw.c:7062

此时，便找到了 异常时的函数，以及函数在文件中的位置

其他类似
