Android SQLiteDiskIOException disk I/O error. But only one place opens the db in my code

This is part of my trace:

I have checked my code, there is only one place to open the db file. It doesn't look like multi-threaded problem. And the crash mostly happened in Android 4.4.4.

Google Cast crash on stop casting

My custom sender application is crashing whenever I'm clicking 'STOP CASTING' on the cast-options menu in the app. The error I'm getting is:

and I can't seem to find anyone with this error. I've followed https://github.com/googlecast/CastHelloText-android/ to the point. I will post the full activity here if it's wanted.

I've found answer on google issue tracking system on https://issuetracker.google.com/issues/37129745
In short, update v7 supprt library to 25.1.1

FirebaseStorage.getInstance().getReference() crashes app

FirebaseStorage.getInstance().getReference() crashes the app. I have checked another similar post but that did not help as my google-services.json file is correctly downloaded from FireBase API and the FireBase assistant shows connection and status as 'OK'.
here's the log:

There was indeed a conflict with the google-play version. Initially, I had used version 9.2.0 for Firebase libraries as I was getting errors with 10.0.0. However fixing the google-play version seems to have taken care of those ones as well. And I am able to run with all the updated libraries.

ProGuard causing Jackson error, "Conflicting property name definitions"

I am using the Nest Android SDK and am getting close to releasing my application. I have found that it is not possible to use Proguard with the Nest SDK as it stands today. Once a user is authenticated, the data that comes back causes the crash below.
How can I get passed this, and still keep ProGuard enabled? I created an issue on the github page but I assume it will not be a high priority by Nest.

Unexplained IncompatibleClassChangeError In Stable Released App Caused by GoogleMaps

I have just received this strange crash report from a user in my Google Play Developer Console.
The app is stable at the moment and this is the first time I have seen this crash. It has been in release for 3/4 months now. The device was a Galaxy S5 running Android Version 5.0.
My initial thoughts is Google Play Services has updated causing issues. Any better offers?

ADDITION Have just found this thread which is about other people experiencing the same crash on Samsung devices.

This was related to issue 8314. This issue has now been fixed via both a Firmware update from Samsung and also an update to Google Play Services.
If this helped you, please mark this as the correct answer.
