Runtime error after extracting strings in Android Studio

I was working on a project which used exclusively strings literals in the code and layout, so I extracted them to strings.xml to later localize. Unfortunately after extracting all the strings and when trying to run I get a runtime error:

Any help or advice would be welcome.

Simply use getString() instead of Resources.getSystem().getString()

WifiAwareManager returns null

I'm trying to create an application that uses Wifi Aware but my WifiAwareManager returns null. How can I properly initialize the class so that it does not return null? What is the cause of this behavior? I'm quite sure that Pixel 2 XL does support Wifi Aware, am I wrong?
final WifiAwareManager wifiAwareManager = (WifiAwareManager) getSystemService(Context.WIFI_AWARE_SERVICE);
if (wifiAwareManager.isAvailable()) {
System.out.println("aware avaiable");
} else {
System.out.println("aware not avaiable");
}
The logcat is:

Cause isAvailiable is added only from api level 26 as WifiAwareManager. I assume you are using android with version lower than Android 8.0

ClassNotFoundException Didn't find class on path: DexPathList

I'm having what I believe to be dex issues, which is something pretty foreign to me. My app crashes when it tries to instantiate an OkHttpClient. I see that a lot of people have this issue, but all the common solutions (which I mention below) haven't helped. Here's my error log:

I see multiple solutions about enabling multidexing, but my app already has multidexing enabled and my manifest also has largeHeap set to true. I've also tried this gradle solution, but it hasn't helped:
dexOptions{
preDexLibraries false
javaMaxHeapSize "4g"
}
Other solutions say to disable instant run, but it's already disabled. Anyone have any suggestions? Please let me know if I need to add anything else to this post.

Trying to run an app using dl4j on Android

I am trying to run a simple app using the deep learning library dl4j.
I am working on Android Studio and using Gradle.
During runtime, I get the following exception:

in the build.gradle file, I have the following dependency:
compile 'org.nd4j:nd4j-native-platform:0.5.0'
but I have also tried different backends.
The dl4j team said Android is not supported yet, but I would still like to try to make it work, so any help would be appreciated.
