この機能のみを備えたアプリケーションを作成したい: - 電話のカメラを使用して画像を撮る - 指定されたアドレスにメールの添付ファイルとして送信する

次のコードを書きましたが、カメラ モードを終了できない理由がわかりません (同意ボタンを押しても効果がありません)。

public class MainActivity extends Activity {
  private static final int CAMERA_REQUEST = 1888; 
    private ImageView imageView;
    private File f;
    public File getAlbumDir()
    {

        File storageDir = new File(
                Environment.getExternalStoragePublicDirectory(
                    Environment.DIRECTORY_PICTURES
                ), 
                "BAC/"
            ); 
        return storageDir;
    }
    private File createImageFile() throws IOException {
        // Create an image file name

        String imageFileName =getAlbumDir().toString() +"/image.jpg";
        File image = new File(imageFileName);
        return image;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        this.imageView = (ImageView)this.findViewById(R.id.imageView1);
        Button photoButton = (Button) this.findViewById(R.id.button1);
        photoButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                try {
                    f = createImageFile();
                    Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                    cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
                    startActivityForResult(cameraIntent, CAMERA_REQUEST); 
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }



            }
        });
    }

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
        if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {  
            Bitmap photo = (Bitmap) data.getExtras().get("data"); 
            imageView.setImageBitmap(photo);

            Intent i = new Intent(Intent.ACTION_SEND);
            i.setType("message/rfc822");
            i.putExtra(Intent.EXTRA_EMAIL  , new String[]{"first.last@gmail.com"});
            i.putExtra(Intent.EXTRA_SUBJECT, "first picture");
            i.putExtra(Intent.EXTRA_TEXT   , "body of email");

            Uri uri = Uri.fromFile(f);
            i.putExtra(Intent.EXTRA_STREAM, uri);
            try {
                startActivity(Intent.createChooser(i, "Send mail..."));
            } catch (android.content.ActivityNotFoundException ex) {
                Toast.makeText(MainActivity.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
            }
        }  
    } 
}

提案をいただければ幸いです。ありがとう！

同じ問題を抱えている人にとって、修正された機能的なコードは次のとおりです。

public class MainActivity extends Activity {
  private static final int CAMERA_REQUEST = 1888; 
    private ImageView imageView;
    private File f;
    public File getAlbumDir()
    {

        File storageDir = new File(
                Environment.getExternalStoragePublicDirectory(

                ), 
                "BAC/"
            ); 
         // Create directories if needed
        if (!storageDir.exists()) {
            storageDir.mkdirs();
        }

        return storageDir;
    }
    private File createImageFile() throws IOException {
        // Create an image file name

        String imageFileName =getAlbumDir().toString() +"/image.jpg";
        File image = new File(imageFileName);
        return image;

            }
        }  
    } 
}
