Does anyone know what a .alias is as far as file type option goes for Android Studio? The one I'm working with is coming up null because android studio associated as a text file.
Resource files are sometimes placed in the wrong folder, and it can lead to subtle bugs that are hard to understand. This check looks for problems in this area, such as attempting to place a layout "alias" file in a layout/ folder rather than the values/ folder where it belongs.
As Per reference from this android documentation.
There is an earlier reference to the alias file as well, in the same documentation. At any rate, I would suggest that you do refer to this documentation and any other official android documentation that you can find for simple tidbits such as the one requested here..
When you generate a resource alias, the resource you are pointing to must be of the same type as the alias
Effectively, this is stating that the alias is a pointer from one false location to a separate true location..
When using google to search for information, you can be more specific by using keywords "OR" and "AND" as well as quoting. To find the above information, I searched google for:
"android studio" AND "alias file"
which brought it to me as the third result. Earlier results being references to stackoverflow - this question, specifically.
There seems to be some additional information available here and here as well.
