应用程序适用于模拟器而不是物理设备：我无法访问我在 Firebase 上定义为 URL 的图像
Application works on emulator not on physical device: I can not access the images I defined as URL on Firebase
我的应用程序在模拟器上正常运行，但是当我将它安装在物理 phone 上时，我无法访问我在 Firebase 中定义为 URL 的图像。所以当我上传应用到phone时，没有图片。除此之外，在实践中一切正常。有什么可以推荐我做的吗？ Android 版本 phone：Android 7 API 24.
这是模拟器

按照这个步骤
前往设置
然后 apps/installed 应用....并搜索您的应用
然后点击打开
并在 App Permission 选项中允许所有权限

我已经解决了这个问题。因为我不打算更改我想看到的图像，所以我自定义了模型 类 变量。我变成了这样;
来自
private String Image;
到
public String Image;
我使用 getter 和 setter 方法查看图像。之后我像这样更改了 FoodList 适配器方法；
Picasso p = Picasso.get();
p.load(model.Image).into(viewHolder.food_image);
如您所见，我也更新了 Picasso。我用的是最新版本。它被用来 get() 而不是 with()。它不需要 getBaseContext().
正如我告诉过你的，我不会更改图像。所以我可以使用 model.Image 如果你的图像是可变的，你需要使用 getter 和 setter 方法，如你所知。
我的应用程序在模拟器上正常运行，但是当我将它安装在物理 phone 上时，我无法访问我在 Firebase 中定义为 URL 的图像。所以当我上传应用到phone时，没有图片。除此之外，在实践中一切正常。有什么可以推荐我做的吗？ Android 版本 phone：Android 7 API 24.
