Why when I import a Text File to my project it shows me an error?
I need the text file to read some info from it and display it on a ListView. Here is a screenshot of what I am talking about.

All data files in this directory must be XML format.
There are several kinds of data you can put here. See http://developer.android.com/guide/topics/resources/more-resources.html for details.
For example:
res/values/strings.xml
<string name="prefs">Version</string>
would be referenced in Java code as
String version = context.getResources().getString(R.id.prefs);
You cannot use a textile to fill a ListView, you should set it on strings.xml, add the String name and his value. @String can be stored and retrieved as resources.
To open raw resources, you need to use openRawResource().
For example, if you're in an Activity, you can open the raw text file as:
InputStream input = getResources().openRawResource(R.raw.textfile);
This returns an InputStream, which allows you to read from your file.
This SO question provides a nice code sample for basic reading of a raw text file.
