Google Tangoを使用してアプリを開発しています。しばらくの間、すべてうまくいきましたが、昨日、いくつかの変数をリファクタリングしていくつかの変更を元に戻した後、突然破綻しました。私は、この行に原因を絞り込んタンゴのアプリがJNIで突然破損するアプリケーションで検出されたエラー

しかし、エラーが私のコードのどの部分を言及していないので、私は「ドンアプリを起動すると、私は次のエラー・ログを取得しますさらに見える場所を知っている。これまでの問題に取り組ん後
私の調査結果：
- リスナーは、コードが含まれているかいないかは関係ありません。
- このエラーは、カメラが画像を取得した直後にのみ発生します。カメラがブロックされるように、デバイスがテーブルに置かれている限り、アプリは技術的に正常に動作します。
- 以前は仕事に使っていましたが、以前のコミットさえも壊れています。
- Googleの基本的な例は正常です。
- 別のバージョンのTangoまたはAndroidを使用しても何も変更されません。
- クリーニングgradleまたはクリーンインストールを実行すると、何も変更されません。
- 私はStackoverflow上の別のスレッドで、原因がライブラリのコードにある可能性があることを発見しました。
誰でもこの問題を解決する方法はありますか？
