@mak12 i got this error make my app crash. it cause by "getProbableActivities()' on a null". can you fix it?

Hi, @LightKnight3r can you share more logs? device android version and other info and if you have any more logs that would be great.

[LightKnight3r]

@mak12 thanks for reply. This error occurs when i use ACTIVITY_PROVIDER and listen location change in background. Whenever user's activity update, ActivityRecognitionLocationProvider will report changes. The function getProbableActivities() from ActivityRecognitionResult return null make app crash

@LightKnight3r got it, will look into it today.

hi @mak12, i make a pull request to handle this issue. Can you check and release it? https://github.com/mak12/background-geolocation-android/pull/2

[mak12]

yes sure will check this too, Have you tested this change? @LightKnight3r

[LightKnight3r]

yes, i think this error cause by changing new flag "FLAG_IMMUTABLE", sometimes ActivityRecognitionResult.extractResult has no result. I fixed by checking hasResult() condition. Maybe can use try - catch. https://stackoverflow.com/questions/70065929/getting-activityrecognitionresult-extractresultintent-as-null-while-trying-t

@LightKnight3r yes that's what I had in my mind, and will try to fix this.
