Figure 11-1 shows that the getWorkContexts() method is called by the WorkManager after the Work instance has been submitted by doWork(), startWork() and scheuleWork(). Chapter 10.3.3.5 states that a WorkCompletedException can be thrown with an appropriate error code which in this case is one of the WorkContextErrorCodes. There is a bit more work in regards to custom contexts if you see the last paragraph in 11.4.2 - the container must always check the most specific context first - and then go up the in hierarchy to find a supported one. You can just attach a single patch with all the changes needed if you don't want to split the patch into separate pieces. And more tests are always good :) You can get additional checkstyle checks by uncommenting | <module name="UnusedImports"/> | in tools/checkstyle/checkstyle.xml. A couple of checkstyle bugs does that we can't enable this module by default at the moment. Thanks for your contributions !
