try-with-resources not supported below API 19

[gautamw]

I noticed that a few of the classes use try-with-resources blocks, which are not supported below API 19. However, the minimum SDK in the manifest is listed as 9.

It seems that try-with-resources "mostly work" down to API 15.
See: https://code.google.com/p/android/issues/detail?id=73483)

I haven't heard of anyone successfully using try-with-resources below API 14, and the support below 19 doesn't appear to be guaranteed. Is there a reason for using try-with-resources in this codebase other than convenience?

Convenience is a good reason as long as the code still works everywhere.

I found this write up, which should provide more info: https://blog.osom.info/2019/10/try-with-resources-desugaring-support.html
