Hallo Herr Wolf,
Ich habe ein Samsung S5duos (G900FD) mit Android 6.0.1 und genau das beschriebene Problem.
Wie kann ich das beheben??

This sounds like the problem described here: https://stackoverflow.com/questions/44862176/request-ignore-battery-optimizations-how-to-do-it-right/50840603#50840603. Unfortunately I have no Samsung running Android 6 to test this myself but maybe you guys can try to have a further look based on this information.

@PhilippNowak96 looks like a good find!
Pushing forward to @svengabr

When taking a look at the Jira tickets, this issue might be resolved with 1.3.0. Could you check again if the error still persists in the latest version?

hi @svengabr ,

EXPOSUREAPP-1885

just to prevent any confusion, and for double checking: this issue here is about CAUSE 10 (android.content.ActivityNotFoundException) - and obviously has more rare effects specifically on Samsung devices running Android 6. The link provided by @PhilippNowak96 https://stackoverflow.com/questions/44862176/request-ignore-battery-optimizations-how-to-do-it-right/50840603#50840603 seems to be rather useful. So, it's not about API 10...
Also, I couldn't find any related PR for 1.3.0 nor for 1.3.1 RC1.

Thanks for checking :)

I also double checked: PR #1116 might have an effect (EXPOSUREAPP-2506) here, but can't understand for which release it's planned.

Hey @vaubaehn

I just checked again today for the ticket I mentioned (EXPOSUREAPP-1885) and it was reopened yesterday by the development team. Internal the ticket was mentioned to be related this is why i thought it could already been fixed.

Hi everyone, I have reopened this issue, since there is no background activity on the Xiaomi devices despite Google's watchdog as long as MIUI energymode is on (by default). BR Katharina

I just corrected the assignee here and gave it to @harambasicluka since he is working on the original Jira issue currently.

Best regards,
SG
