How do we look at the crash point at this time, you can use Address2line.

My Mac version of ndk_r8e, which is located in

$NDK/toolchains/arm-linux-androideabi-4.4.3/prebuilt/darwin-x86_64/bin;

You can add this path to the environment variable and execute the following command in the project's root directory.

Arm-linux-androideabi-addr2line-c-f-e obj/local/armeabi/libxxx.so <address>

The address here is the starting point for the crash, #00 the one at the back of the PC. Like we can see the crash information on line 9th gets the address 006d372e.

Arm-linux-androideabi-addr2line-c-f-e obj/local/armeabi/libxxx.so 006d372e

Can see the last wait for this information

./arm-linux-androideabi-addr2line-c-f-e obj/local/armeabi/libgame.so 006d372e

finally found a problem.
