问题
我目前正在构建一个简单的图像查看器应用程序（您可以在其中查看图像）。
考虑这种情况，您刚刚从互联网上下载了一张图片，现在您使用文件浏览器滚动到该图片（该文件浏览器内置于安卓手机中），然后按“打开方式”。目前，在您按“打开方式”时会出现一个“图库”（内置应用）和其他应用，但是我的应用程序不在其中。我该如何解决这个问题？以及我如何打开这张图片？
您只需考虑在我的应用程序中加载图像的函数为
imageViewer.loadImage(getIntent().getData()))。
英文:
Application I am currently building a simple image viewer application ( that you can view an image in)
Consider this scenario, you just downloaded an image from the internet and now you scroll to the image using file explorer ( which is built into the android phone) and press on "open with". Currently, there is a "Gallery" (built-in application) and other applications present when you press "open with" but my application is not present. How can I fix this? And how do I go about opening the image?
you can just consider the function that loads the image in my application to be
imageViewer.loadImage(getIntent().getData()))
