【中文标题】上传图像在某些设备上有效，但返回 Stream FixedLengthSource .inputStream()【英文标题】：Uploading a Image Works on some devices but returns Stream FixedLengthSource .inputStream() 【发布时间】：2020-12-22 14:58:32 【问题描述】：我正在开发一个使用 php 和 okhttp 将图像上传到指定目录的 android 应用程序。嗯，前端和后端在我的个人设备上运行良好，但在非三星设备上崩溃。
当我挖掘问题时，我发现服务器返回：
com.android.okhttp.internal.http.Http1xStream$FixedLengthSource@17768aa).inputStream() 在非三星设备上。
文件上传的Java代码如下：
public class UploadGalleryStoryPost

尝试将缓冲区大小从 1024 增加到 2048 仍然无法在其他设备上运行。

【讨论】：
感谢您的回复，但从相机拍摄的图像上似乎仍然存在问题。从相机拍摄的图像转换为位图，也转换为 base64 字符串。但是在上传时仍然会由于某种未知原因引发错误。 我认为您正在使用 AsyncTask 。但是当涉及到 android 10 时他们有一些问题 .. 但是您可以按照我的步骤进行操作，并且效果很好。如果您认为我的回答对您的问题有帮助吗？您可以对我的个人资料提供反馈吗以上是关于上传图像在某些设备上有效，但返回 Stream FixedLengthSource .inputStream()的主要内容，如果未能解决你的问题，请参考以下文章
