処理（バージョン3）でqrコードスキャンのコードを実行しようとしています。私はすでに提供されているQRコードライブラリのサンプルコードを使用しています。私はJDK 8とアンドロイドSDKもインストールしていますが、まだアンドロイド携帯電話でアプリケーションを実行することはできません。インストール中ですが、実行中に閉じます（「残念ながら、QRコードの例が停止しています」を示しています）（私はいくつかの例を試してみました。QRコードスキャナアンドロイド携帯で実行していないQRコードライブラリの処理例コード
ここでは、リファレンスとコンソールに表示されたエラーのコードだけを追加します（これはサンプルコードであり、変更はしません）。私はプログラミングに慣れていないので、エラーの内容を正確に把握することはできません。誰かが見て、私を助けてください。
ありがとうございます。
/*
QRcode reader
Generate images from a QRcode generator such as
http://qrcode.kaywa.com/ and put them in this sketch's
data folder.
Press spacebar to read from the camera, generate an image,
and scan for barcodes. Press f to read from a file and scan.
Press s for camera settings.
