how to implement @drawables? App doesn't build because it doesn't find the resource

I am styarting with the Choose your own adventure Android App, and I have stumbled uppon something I haven't been able to figure out for a couple of hours.

DATA:

• AndroidStudio v 1.2.2, the course is based on v0.86 I think
• OS / DE: Manjaro Linux, KDE

I have copied the image files inside the drawable folder, each into their specific dpi folder.

Project files won't run on my machine, even though I updated every requisite shown to me by Android Studio

I have created the ImageView for the mail_title.png, and added the src as the full path to the png. When I do that, the image loads into the preview screen, and I can work with it, but If I try to build the app it just says the value of src cannot be a string.

So then I tried to point to it as a resource. On many forums and the android documentation I only found that I should reference it through a "pointer" @drawable/main_title , when I downloaded the projectfiles from the course I saw thats how they did it too.

If I try to rebuild now it gives the following error:

Error:(14, 22) No resource found that matches the given name (at 'src' with value '@drawable/main_title').

Then I tried to create a resource inside strings.xml, I found some autocomplete function that pointed me in "the right direction", of course it did not work!, same error as before. I have tried using absolute paths as well without luck.

I somehow suspect it has something to do with the IDE itself, right now It shows R as "cannot resolve symbol R" in the MAinActivity file. I figured out by reading online that this is due to my drawable not existing problem.

Then I created a refs.xml in values and added

<?xml version="1.0" encoding="utf-8"?> <resources> <drawable name="main_title">main_title.png</drawable> </resources>

I actually tried with and without the extension (png)

After that I clicked on the IDE suggestion to create a drawable folder and it just created a @drawable folder inside of layout....

Basically it says it cannot resolve directory @drawable from activity_main.xml

and also Error:(3, 33) String types not allowed (at 'main_title' with value 'main_title.png'). on the refs.xml file (this happens whether I use the extension (png) or not.

So, as you can see I'm kinda lost... Any help would be appreciated. I'm a python backend developer and I'm pretty comfortable usiong Pycharm (IntelliJ for python), but somehow I feel Android Studio keeps failing me!
