【问题描述】：

我有一个应用需要访问用户的图库才能选择图像并对其执行转换。我想将此功能移植到免安装应用体验中。我知道READ_EXTERNAL_STORAGE 权限不适用于即时应用，但ACTION_GET_CONTENT 或new ActivityResultContracts.GetContent() 我们不需要它。

我可以打开图库并选择一张图片，但是当我尝试访问它时出现此错误：

class j1.q: Failed to load resource
There were 3 causes:
    java.io.FileNotFoundException(No content provider: content://com.android.providers.media.documents/document/image%3A221)
    java.io.FileNotFoundException(No content provider: content://com.android.providers.media.documents/document/image%3A221)

        Cause (4 of 4): class j1.q: Failed LoadPathHierarchicalUri->Bitmap->Bitmap, LOCAL
        Cause (1 of 1): class j1.q: Failed DecodePathHierarchicalUri->Bitmap->Bitmap

我在 4 年前就看到过这个问题 Not able to launch Gallery from Android Instant app

现在我们可以打开图库了，所以也许谷歌方面对这个主题做了一些更改。

有人可以在免安装应用上从图库中获取图片吗？
