Android-job: [1.2.0-RC1] Didn't find class "android.app.job.JobServiceEngine"

[MateuszMlodawski]

Hey,

looks like version 1.2.0-RC1 doesn't work on pre-Oreo devices.
While adding JobCreator in the Application class JobManager.create(this).addJobCreator(new SampleJobCreator()); the following error about missing android.app.job.JobServiceEngine class occurs:

Launching on Oreo looks fine.
Am I missing something in configuration for pre-Oreo devices?

[MateuszMlodawski]

OK, looks like jobs are scheduled correctly and they work also on pre-Oreo devices (my mistake, sorry!).
The error above is still visible in logs. It would be great to get rid of it.

[vRallev]

I just checked the logs with an API 21 emulator and don't see the exception. Which device are you using? I know that Samsung sometimes logs unnecessary errors. Also, this class is coming from the support library, so even if I would like to change it, I cannot do it.

[vRallev]

Closing because of inactivity.

Also seeing this on Nexus 6 Android 7.1.1 logcat.

On further investigation, it looks like "android.app.job.JobServiceEngine" is only available on Oreo.

I just changed my build.gradle minifyEnabled to false:

...
minifyEnabled false
useProguard true
...

After that, this issue is not showing up.

I did not figure out what the hell was going on.

[phileo]

It sounds like it could be a V4 support library issue with trying to call a new API (API 27) on older devices (ie. Android 7.x).
I have filed ticket with Google's Issue Tracking system.

Please follow this link and star the issue, hopefully that will give it enough attention for Google to expedite a fix.
