MIUIでのカメラプレビューの不具合（MIUIユーザ/開発者の助けが必要）

Question

カメラの点滅と誤ったプレビュー画像が表示されます（詳細はthisを参照）。私はMIUI（Android 5-7）ユーザーからも同様のレビューを得ていますが、テスト用のMIUIを搭載したデバイスはありません。 1人のユーザーの助けを借りて、私は彼の装置からログを取得しました。しかし、残念ながら、私は失敗の正確な原因を特定することはできません。

ログ（唯一の最も重要な部分）

MIUIユーザー、あなたもGoogle Playで自分のアプリケーションをテストする（負のレビューを残すしないでください）、あるいはどの段階でチェックするために、独自の新しいプロジェクトを作成することができますエラーが発生します。プロジェクトは以下のようにする必要があります：

• android.hardware.Camera（これは非推奨ですが、私はアンドロイド4でユーザーをサポートしたいと思います。）出力用
• 使用TextureView（私はonSurfaceTextureUpdated方法で色の決意のビットマップを取る。）

私はこれがなぜ起こるかわかりません。バグの原因を特定するのを助けてくれることを願っています。
