Content Query "subdirectories" non-recursive

[Ricardo Fernández Serrata]

I want to know how to get all valid paths for a specific URI. For example (not just a example, because it's my specific problem), if the URI is content://settings, I want to get an array similar to this ["system", "secure", "global"] preferably sorted by their IDs, such that I can get their IDs just by looking at the index. Or even better, a dictionary where the keys are the setting categories, and the values are their corresponding IDs, like this {"system": 0, "secure": 1, "global": 2}.

I want this to work with any other provider, not just settings please

Only the content provider, i.e. the app handling the URI knows the URIs it supports, and there's usually no "directory" of them.

Thanks but, what input arguments should I use in the Content Query?

I've tried these:

Where: type='table'

Where: type='base_table'

Where: * ("any" wildcard char)

Where: type='*'

Limit: 1

Limit: null

And other values and combinations I read online. But I always get the same error:

java.lang.IllegalArgumentException: Supported SQL

As said, there's not "directory" of tables.

[Ricardo Fernández Serrata]

So there's no way of "asking" (requesting) a content provider even for a small subset of valid URIs?

Well, at least we tried. Thanks anyways

[Henrik "The Developer" Lindqvist]

No, not as standard.

I found (again) this flow: llamalab.com/automate/community/flows/37254

Which answers 1 of my questions. I want to apologize to everyone in the community for asking a duplicate.

However, about the general-case question, the best way to get a list of valid URIs is (still) reading the documentation of the content provider in question. Or if the content provider has an URI that points to a table of metadata, then requesting data from that URI is enough to get a list of URIs.

Thanks to everyone for their time
