问题
According to the documentation, jobs must have a unique Job ID per uid.
If I use a 3rd party library which also schedules jobs, does this mean I can't use the same Job ID as theirs? If so, how can I avoid these kind of collisions?

Correct.
If so, how can I avoid these kind of collisions?
Ask the developer of the library what job IDs they use, or if those job IDs are configurable somehow.
回答2:
If asking the developer of library doesn't work, you may want to calculate md5 on package name and pick last 4 bytes as unique id. The chances of collision will be quite less.
