根据报错,肯定是sensors.qcom引起的,我们在out目录查找该文件:

./out/target/product/msm8952_64/system/bin/sensors.qcom
./out/target/product/msm8952_64/symbols/system/bin/sensors.qcom

注意:

1.一个地方必须使用symbols目录下的sensors.qcom文件,否则解析不出来,其它的.so文件也是一样的必须使用该目录的文件!!!

2.so或者应用程序一定要是出问题版本,即使是同一个项目的不同软件都不能代替.

在根目录执行命令:

addr2line -C -f -e ./out/target/product/msm8952_64/symbols/system/bin/sensors.qcom 0000000000015ee4

结果:
sns_main_handle_ctl_sock
vendor/qcom/proprietary/sensors/dsps/sensordaemon/main/src/sns_main.c:1324
