android - Glide - 加载失败的图像大小

问题描述

我有以下代码行，Android App但Glide拒绝向我显示图像：

requestManager.load(profilePicturePath).into(binding.profilePic)

调试显示profilePicturePath有值/media/Images/place.jpg。该文件存在于我的本地Django开发服务器上。我可以通过PostMan.

但是在Android库Glide中，我收到以下错误消息：

2020-11-22 15:24:08.846 7284-7284/com.example.project W/Glide: Load failed for /media/Images/place.jpg with size [1080x1437]

我的问题：

1.) Why is this error happening ? 
2.) The image `place.jpg` has the dimension width=316 and height=159 . But Glide states that the image size is [1080x1437]. Why?

解决方案

这是由于范围存储。在 andriod Q 或更高版本中，您无法直接从图像路径访问。您可以使用：

android:requestLegacyExternalStorage="true" android:preserveLegacyExternalStorage="true"

这两个在清单中的应用程序标记中，因此它适用于 android Q，但不适用于下一个版本。您需要实现 Mediastore API
