Answer 1

    public void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);

           if (requestCode == CAMERA_REQUEST  && resultCode == getActivity().RESULT_OK)       {
                   File file = new File(mCapturedImagePath);
                   file.delet();
            }
    }

or  u can use only this(as your condition)
File file = new File(mCapturedImagePath);
file.delet();

Answer 2

File file = new File(Environment.getExternalStorageDirectory()+"image_name"); //if your image is directly inside sdcard
file.delete();

Answer 3

使用以下代码可能对您有所帮助。

File fdelete = new File(file_dj_path);
    if (fdelete.exists()) {
        if (fdelete.delete()) {
            System.out.println("file Deleted :" + file_dj_path);
        } else {
            System.out.println("file not Deleted :" + file_dj_path);
        }
    }

删除图片后刷新图库的代码

sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED,
 Uri.parse("file://" +  Environment.getExternalStorageDirectory())));
