我正在尝试上传图像，但如果 Android 设备上的图像文件超过 ~2 兆，我会收到一些内存不足错误。
File file = new File(<my image file>);
FileInputStream fis = new FileInputStream(file);
HttpClient client = new HttpClient();
PutMethod method = new PutMethod(myUrl);
RequestEntity requestEntity = new InputStreamRequestEntity(fis);
method.setRequestEntity(requestEntity);
client.executeMethod(method);
executeMethod 行发生内存不足错误。我如何更改它以读取流，而不是将整个流读入内存并导致崩溃？

最佳答案
构造不带长度的InputStreamRequestEntity会导致它在本地缓冲数据，以便确定长度。由于您将其作为文件，因此请使用 FileRequestEntity 来代替，因为它将确定文件的大小。
