推荐答案

使用本机意图获取图像时，它将返回原始图像.图片大小过大(将近2MB)，最好将其压缩并上传.

While getting images using native intents it will return original image. Image size is too large (nearly 2MB) better compress the image and upload it.

ByteArrayOutputStream bytes = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.PNG, 80, bytes);
