用于上传图像的 Iphone 代码有效，但在 android 中尝试相同的代码会给出状态代码 200 但图像无法上传。

安卓代码

    HttpClient httpclient = new DefaultHttpClient();

    HttpPost httppost = new HttpPost(
            "<URL>");

    String boundary = "0xKhTmLbOuNdArY";

    httppost.setHeader("Content-Type", "multipart/form-data");

    File file = new File(Environment.getExternalStoragePublicDirectory(
            Environment.DIRECTORY_DCIM).toString()
            + "/Camera/Test.jpg");

    Bitmap bitmap = BitmapFactory.decodeResource(getResources(),
            R.drawable.ic_lock_idle_alarm);
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.PNG, 60, baos);
    byte[] BitmapData = baos.toByteArray();


    ByteBuffer buffer = ByteBuffer.allocate(800 * 800 * 4);
    // StringBuffer buffer = new StringBuffer();

    String p1 = new String(("--\r\n" + boundary).getBytes(), "UTF-8");
    String p2 = new String(
            ("Content-Disposition: form-data; name=\"picture\"; filename=\"Temp.jpg\"\r\n")
                    .getBytes(), "UTF-8");
    String p3 = new String(("Content-Type: image/jpeg\r\n\r\n").getBytes(),
            "UTF-8");
    String p4 = new String(("\r\n").getBytes(), "UTF-8");
    String p5 = new String(("--" + boundary + "--\r\n").getBytes(), "UTF-8");

    buffer.put(p1.getBytes());
    buffer.put(p2.getBytes());
    buffer.put(p3.getBytes());
    buffer.put(BitmapData);
    buffer.put(p4.getBytes());
    buffer.put(p5.getBytes());

    ByteArrayEntity entity = new ByteArrayEntity(buffer.array());


    httppost.setEntity(entity);
