我尝试从Android Studio上传图像/视频，这在所有其他Android版本中运行良好，但面临与牛轧糖的问题。
任何人都可以帮助我做到这一点。

答案 0 :(得分：2)
问题在于这一行（无论何处写）
Uri fileUri = Uri.parse(uri);
此行为在Android Nougat中已更改。与牛轧糖达到同样的效果
请关注this thread作为参考。当您将targetSDK设置为24并更改以下内容时，它将向您展示如何使用文件提供程序。在private static Uri getImageFileUri()方法
更改此行
Uri fileUri = Uri.parse(uri);
到
Uri fileUri = FileProvider.getUriForFile(context, context.getApplicationContext().getPackageName() + ".provider", createImageFile());
希望这可以帮助您解决问题。
