エラー：roboelectricとrealmを持つjava.lang.UnsatisfiedLinkError

Question

こんにちは私はアプリケーションのためにrealmデータベースを使用しており、ユニットテストを実行するためのユニットテストフレームワークroboelectricを使用しています。私はrealmがネイティブCコードで書かれているのを参照してください、それはその機能のためにlibrealm-jni.soファイルを持っています。

私はUnsatisfiedLinkErrorエラーが発生していますが、robolectricはネイティブライブラリをサポートしていません。それを解決するには何らかの方法が必要だと私は信じています。私はこのHow to load .so when using Robolectric?の回答を受け入れようとしましたが運はありませんでした。

チェックこのout

RealmがRobolectric（まだ）をサポートしていないことは未解決の問題です。
