v.5.1.0: Sending reports from Application.attachBaseContext causes a crash

[ZimM-LostPolygon]

Since 5.1.0, ACRA uses JobIntentService for SenderService. However, JobIntentService.CompatWorkEnqueuer (for pre-Oreo devices) constructor does this:

mContext = context.getApplicationContext();

as result, mContext is null, so everything else fails. This is probably an issue with the support library itself, but for ACRA, this means that ACRA.init can't be called in Application.attachBaseContext anymore.

Calling ACRA.init from Application.onCreate instead makes everything work again.

Cannot reproduce.

SenderService should not be called in init anyway. Please detail your setup.

SenderService should not be called in init anyway.

It does when there are unsent crash reports. Here's the full stacktrace:
