Build failure due to un-pinned dependencies

[sel]

The dependency to recyclerview-v7 is not pinned to a specific revision. Since the refactor of the Android support-v4 library this causes a build failure due to duplicate class files (see below for the error message).

This can be fixed by setting the revision of recyclerview-v7 to 24.1.1 (i.e. to match the other support library versions). Additionally, appcompat-v7 is included twice; once un-pinned. The latter inclusion should be removed.

Build failure:

Execution failed for task ':Application:transformClassesWithDexForDebug'.
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.dex.DexException: Multiple dex files define Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl;

I don't get the same build failure but I can confirm that pinning this dependency fixes the build failure I get:
