使用Volley上传图像（超过2 MB）时出错

我在上传超过2 MB的图片时遇到了问题 . 请帮助我解决这个问题 . 这个错误

java.net.SocketException：管道损坏

显示在 Toast 中 .

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;
}

    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);

        } catch (IOException e) {

这是我的代码..
