Troubleshooting
1

the android_prc_test.py script succeeded, however if I run an actual auto-tuning task, it always crashes due to this local reference overflow, looks like an issue in java binding library.

I meet the same issue with the latest code. @yongsun have you fixed this problem?

No, I used cpp_rpc in the end, build it with ndk.

@yongsun, Thanks, I will try it!
