使用Volley上传图像（超过2 MB）时出错

Question

我在上传超过2 MB的图片时遇到问题。 请帮我解决这个问题。这个错误

  

java.net.SocketException：Broken pipe

以 Toast 显示。

这是以Base64格式获取图像并在服务器上上传的代码。

public String getStringImage(Bitmap bmp){
    ByteArrayOutputStream baos=new  ByteArrayOutputStream();
    bmp.compress(Bitmap.CompressFormat.JPEG,100, baos);
    byte [] b=baos.toByteArray();
    String encodedImage= null;
    try{
        System.gc();
        encodedImage= Base64.encodeToString(b, Base64.DEFAULT);
    }catch(Exception e){
        e.printStackTrace();
    }catch(OutOfMemoryError e){
        baos=new  ByteArrayOutputStream();
        bmp.compress(Bitmap.CompressFormat.JPEG,50, baos);
        b=baos.toByteArray();
        encodedImage=Base64.encodeToString(b, Base64.DEFAULT);
        Log.e("EWN", "Out of memory error catched");
    }
    return encodedImage;
}

private void uploadImage(){
    //Showing the progress dialog
    final ProgressDialog loading = ProgressDialog.show(getActivity(), "Uploading...", "Please wait...", false, false);
    StringRequest stringRequest = new StringRequest(Request.Method.POST, Constant.UPLOADIMAGE_URL+"/user",

        if (pairs.getValue() == null) {
            map.put(pairs.getKey(), "image");
            map.put(pairs.getKey(), "id");
        }
    }
    return map;
}

private void showFileChooser() {
    Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);
    startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);


    if (requestCode == PICK_IMAGE_REQUEST && resultCode == getActivity().RESULT_OK && data != null && data.getData() != null) {
        Uri filePath = data.getData();
        try {
            //Getting the Bitmap from Gallery
            bitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), filePath);
            //Setting the Bitmap to ImageView

            userImage.setImageBitmap(bitmap);
            uploadImage();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

这是我的代码..
