28. Summary

29. The Good
1. The library size for android is very small.
2. Super easy to integration(live version).
3. Flexible : more use case, e.g, FCM
+Crash User, BigQuery Integration…etc

30. We Hope
1. Remote config : multi-conditional
experiment.
2. Android SDK depends on the right
google play service version.
• so it’s not all of android phone can use. e.g, Amazon Kindle
3. Analytics :
• Open funnel is weird.
• Limitation of User Property
user property limitation : https://support.google.com/firebase/answer/6317519?hl=en&ref_topic=6317489
