Very interesting, thanks!

I dont get it

I would like to see more Native American mythology.

For me, less spam, bots, recycled posts.

I would try app:src or adding

 android {  
   defaultConfig {  
     vectorDrawables.useSupportLibrary = true  
    }  

To your build.gradle

Type package:mine level:error in the text bar and see if any errors are returned.

And what is the path of your image, and how are you placing the image in your xml file? Here is an example of one that works for me with an image that is located in the res/drawable/baseline_arrow_back_24.xml package

  <ImageView
        android:id="@+id/backButton"
        android:layout_width="42dp"
        android:layout_height="42dp"
        android:layout_gravity="start"
        android:layout_centerVertical="true"
        android:src="@drawable/baseline_arrow_back_24"
        android:contentDescription="@string/back_arrow" />

Do any errors show in logcat? You should be able to filter to show errors only.

Is it not showing up in the emulator, or the phone on which the app is downloaded, or both?

Damn, where do you live?

I would like to see nuclear power grow in use.

Exactly, and it seems like that is a realistic outcome.

I would love to see large and small scale nuclear reactors become more common.

I am suprised to see all the negativity. I for one think this is awesome and would love to see SMRs become more mainstream.

I had did a premium trial and totally agree. I am always suprised by the people who expect a service as big as youtube to be entirely free.

Not super rare, but a wolverine

Yes, as annoying as apps for everything is, very few are necessary, or even useful. I have had no problem going though life with minimal apps.

What?

Fancy cologne.
