Thank you for your contribution! I'll review it in the next few days.

1. don't worry about the failing Travis CI build. It's just broken for pull requests from external repositories.
2. you asked for feedback, so... I noticed that you mentioned the issue Drag and drop to rearrange items in Stored Recordings list #23 in a commit message. and you could also refer this issue in PR description, like "fixes Drag and drop to rearrange items in Stored Recordings list #23", for convenient navigation. anyway, it's not a big deal =)

@axel-legue you've implemented records reordering and it's working fine.

After manual testing I discovered the following issues:

• Crashlytics initialization fails with the following exception: "UnmetDependencyException The Crashlytics build ID is missing. This occurs when Crashlytics tooling is absent from your app's build configuration. Please review Crashlytics onboarding instructions and ensure you have a valid Crashlytics account."
• User can't listen to records. In this app, user can go to "saved recordings" tab and tap on any item in list to open a Media Player (see PlaybackFragment). But now it doesn't happen.
• Travis CI build fails.

Possible solutions:

• don't change Crashlytics initialization code! revert Fabric.with(this, new Crashlytics()); to Fabric.with(fabric);
• I suggest adding a drag handler for each item. A user can reorder items by holding this handler, and a user can open recordings for listening by tapping on items. Refer to https://material.io/design/components/lists.html#behavior for example (see Behaviour > Gestures).
• ignore Travis CI build for this Pull Request. if your local build fails due to Crashlytics, just add fabric.properties file with apiSecret and apiKey to the project root directory. DO NOT commit this file to Github.

Please fix the first two issues and then I review this PR again.
