did you manage to solve the issue?

Hi @haoXu1990,

I've moved this issue to the Unofficial Support Discussion forum since Android is not a Tier 1 platform (you can check out our supported platforms here) and according to our CONTRIBUTING guidelines this is the proper place for such issues.

I've tried reproducing your issue without success. Could you provide some additional information regarding your project configuration (like compilation flags and environment variables used during build process)? A reproducer would be helpful as well.
