Crash on Android

[ghost]

Using:

• X-Code 8.3.x
• Android Studio 2.3.3 on macOS, with SDK 25 installed
• Realm Server on Virtualbox hosted VM with Ubuntu 16.04, latest as of 2017-09-13
• RealmTasks latest commit as of 2017-09-13

To reproduce:

• Start X-Code 8 and install/run app, pointing to local dev Realm Server
• Create account, which creates a realm on the dev Realm Server
• Start Android Studio, invoke Nexus 6 API 25 emulator
• Uninstall any previous version of realm-tasks, if applicable, to be sure
• Modify app/build.gradle to point to IP address of Realm Server (on local subnet, confirmed working with iOS version of RealmTasks)
• git clone https://github.com/realm-demos/realm-tasks/issues/new
• cd realm-tasks
• ./gradlew installDebug
• Open emulator and start RealmTasks
• Try to log in with the same account that you created on iOS
• Crash:

Sorry if this is simply a newbie issue that has an easy solution. Maybe setting the server IP in app/build.gradle for the Realm Server is not sufficient? Is there something that needs to be done to coordinate schema versions between the already-created realm on the Realm Server and the new Android install? Just playing around to try out the tech for our startup.

Please LMK if more info is needed.

I think using a newer version of Realm would fix that
