널포인트 발생인데;;; 어디가 문제가 ;; ㅠ 소스는

public void takePicture(final String title, final String description, final String gelPath)

{

mCamera.takePicture(null, null,new PictureCallback()

{

public void onPictureTaken(byte[] data, Camera camera)

{

BitmapFactory.Options options = new BitmapFactory.Options();

options.inSampleSize = 2;

Bitmap bitmp = BitmapFactory.decodeFile(gelPath, options);

picture = BitmapFactory.decodeByteArray(data, 0, data.length);

MediaStore.Images.Media.insertImage(mContext.getContentResolver(),

overlayMark(picture,bitmp,250,250), title, description);

Toast.makeText(mContext, "이미지가 저장 되었습니다.", Toast.LENGTH_SHORT).show();

mCamera.startPreview();

}

});

}

private Bitmap overlayMark(Bitmap baseBmp, Bitmap overlayBmp, int distanceLeft,int distanceTop)

{

    Bitmap bitmap1 = Bitmap.createBitmap(baseBmp.getWidth() + distanceLeft, baseBmp.getHeight() + distanceTop, baseBmp.getConfig());

    BitmapFactory.Options options = new BitmapFactory.Options();

    options.inSampleSize = 2;

    Bitmap resultBmp = Bitmap.createScaledBitmap(bitmap1, 100, 100, true);


    Canvas canvas = new Canvas(resultBmp);

    canvas.drawBitmap(baseBmp, distanceLeft, distanceTop, null);

    canvas.drawBitmap(overlayBmp, 0, 0, null);

    return resultBmp;

} 

이부분에서 오류가나구요;;;

gelPath 는 다른파일에서 

 mCaptureButton = (Button)findViewById(R.id.capture_button);

        mCaptureButton.setOnClickListener(new OnClickListener()

        {

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

String gelPath = "/mnt/sdcard/picture/temp1.jpg";

mPreview.takePicture("MyPhoto", "Photo taken by sample application",gelPath);

}

        });

파라미터로 받고잇습니다..

도와주세요 ㅠ
