适用于content://Android 9及更高版本上的URI的Intent-Filter [英] Intent-Filter for content:// URI on Android 9 and higher
问题描述
我想编写一个意图过滤器，该过滤器将允许我的应用打开自定义文件例外的文件.在Android 8(及更低版本)上，有可能这样做，因为这样发送了意图网址(来自Chrome下载屏幕):
I want to write intent-filter that will allow my app to open files with custom files exception. On Android 8 (and before) there was a possibility to do this as intent url was delivered like this (this comes from Chrome downloads screen):
content://com.android.chrome.FileProvider/downloads/somefile.xyz
现在，Android 9+上的同一屏幕传达了这样的意图:
Now, the same screen on Android 9+ delivers intent like this:
content://media/external/downloads/25
是否有可能用这种intent-uri格式检测我的文件扩展名，而无需编写仅检测所有intent(*)的intent过滤器?
Is there a possibility to detect my file extension with such intent-uri format without writing an intent filter that just detects all intents (*)?
任何帮助将不胜感激！

不，抱歉.

在任何版本的Android上，都不需要content Uri包含文件扩展名，就像Web上不需要http或https URL包含文件扩展名一样.文件扩展名.
There is no requirement, on any version of Android, for a content Uri to contain a file extension, just as there is no requirement on the Web for an http or https URL to contain a file extension.

对于特定版本的Chrome可能是正确的.请不要以为Chrome浏览器将始终使用文件扩展名.而且，请不要假设每个Android设备用户都使用Chrome，并且仅 使用Chrome.无需其他应用程序使用带文件扩展名的content Uri.
That may be true for a particular version of Chrome. Please do not assume that Chrome will always use a file extension. And please do not assume that every Android device user uses Chrome and only uses Chrome. There is no requirement for other apps to use a content Uri with a file extension.
