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.

I am writing an Android app using Kotlin.
I am receiving NoClassFoundError for java.util.stream.Stream.
At no point in my app am I using that class.
It happens when I open an ad and appears to be part of the serialization process.
It does not happen on all my devices. Only on my older one (5.1.1).
It also does not happen on all the activities.
I'm guessing that it is to do with what it is trying to Serialize. However, I am not sure where to even start.

As documentation says java.util.stream require API level 24 or higher. Android 5.1.1 is API 22, it doesn't have java.util.stream.Stream class.
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

2-I have another question :) how can I change my button background when sb buy my app(for example change its test from Buy to Read)
how can I fix them... tnx in advanced.
I have been constructing a Facebook login for my android app. For some reason it keeps on crashing. I have followed this tutorial to the letter, and copied whole parts of this guys code (besides the part for copying photos, I removed anything picasso related and the xml elements belonging to it. I have also removed the textview with the user name.):
https://www.youtube.com/watch?v=LPG7Rxj3u94
https://github.com/delaroy/AndroidFacebook/blob/master/app/src/main/java/com/tutorialsbuzz/androidfacebook/LoginFragment.java
I have already checked my manifest, my gradle.build files to ensure i have the right dependencies. I have checked my app ID at facebook, and have input the ssl key. Lastly I have indeed initialized the FacebookSDK before trying to inflate any xml in the loginactivity.
at the moment I don't know what the error is...
Here is my error message:

If you need anything else besides this let me know!
Thank you for your help!
I am trying to use RecyclerView in my project, but because we have some bad proxies, I cannot afford to add compile "com.android.support:recyclerview-v7:+" to my build.gradle because the download is very slow. Instead, for the other libraries, I simply added the .jar files to the 'libs' folder of the project and in build.gradle I have compile files('libs/android-support-v7-recyclerview.jar'). I got the .jar from the Android SDK under /extras/android/support/v7/recyclerview/libs.
I got the android-support-v4 library from the same place and it works fine.
The app is building, but at runtime, I get a NoClassDefFoundError. The behavior can be replicated using Google's RecyclerView sample found in /samples/android-21/ui/views/RecyclerView by replacing in Application/build.gradle these lines:
compile "com.android.support:support-v4:21.+"
compile "com.android.support:gridlayout-v7:21.+"
compile "com.android.support:cardview-v7:21.+"
compile "com.android.support:recyclerview-v7:+"
With these ones:
compile files('libs/android-support-v4.jar')
compile files('libs/android-support-v7-gridlayout.jar')
compile files('libs/android-support-v7-cardview.jar')
compile files('libs/android-support-v7-recyclerview.jar')
And adding the 4 jar files from the same SDK to Application/libs (you need to create the folder as it doesn't have one).
The full error log generated by the Google sample:

I also tried, as people suggested, to use the classes.jar found in extras/android/m2repository/com/android/support/recyclerview-v7/23.3.0/recyclerview-v7-23.3.0.aar but the result was exactly the same.
Any hints on what I might be missing/doing wrong?
The jar file doesn't have all the necessary source code in it. You have to use the aar file instead.
Please check this thread how an aar file can be included in your project.
