I think this is a problem related to the emulator and not the physical device.

I used this code and I got a bitmap:

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        captureButton = (Button)findViewById(R.id.capture);
        captureButton.setOnClickListener(listener);

        imageView = (ImageView)findViewById(R.id.image);

        destination = new   File(Environment.getExternalStorageDirectory(),"image.jpg");
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if(requestCode == REQUEST_IMAGE && resultCode == Activity.RESULT_OK) {
            //Bitmap userImage = (Bitmap)data.getExtras().get("data");
            try {
                FileInputStream in = new FileInputStream(destination);
                BitmapFactory.Options options = new BitmapFactory.Options();
                options.inSampleSize = 10; //Downsample 10x
                Bitmap userImage = BitmapFactory.decodeStream(in, null, options);
                imageView.setImageBitmap(userImage);
            } catch (Exception e) {
                e.printStackTrace();
            }

        }
    }

    private View.OnClickListener listener = new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            //Add extra to save full-image somewhere
            intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(destination));
            Toast.makeText(JMABarcodeScannerActivity.this, Uri.fromFile(destination).toString(), Toast.LENGTH_SHORT).show();
            startActivityForResult(intent, REQUEST_IMAGE);
        }
    };
}

Main.XML

          <?xml version="1.0" encoding="utf-8"?>


          <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:orientation="vertical"

          android:layout_height="fill_parent">
      <Button
    android:id="@+id/capture"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="Take a Picture"
      />
      <ImageView
    android:id="@+id/image"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:scaleType="centerInside"
       />
          </LinearLayout>
