Can't add .so file to Android Studio 3.5.3 using jniLibs

I'm trying to add a .so file to a new Android project. I'm using Android Studio 3.5.3. I've done what was recommended here and here ; so I created folders (jniLibs/arm64-v8a, etc) in src/main and added this to app/build.gradle:
sourceSets {
main {
jniLibs.srcDirs = ['src/main/jniLibs']
}
}
I placed the libhl.so file in /app/src/main/jniLibs/arm64-v8a (yes, 64-bit should be ok). The project will compile just fine, but on execution it will show the following error in logcat:
02-17 10:25:31.719 3691-3691/com.example.bmdtest03 E/AndroidRuntime: FATAL EXCEPTION: main

Conclusion: the file is there, the source is updated in build.gradle, what am I missing?

You can manually generate the .so file with NDK . Then you can add the lib.so file in your jni folder.
Add the NDK path to your local.properties.
Refer this page : https://developer.android.com/studio/projects/gradle-external-native-builds
If its not works. You can create javah then you can access it.

The fact that the class is found in debug but not in release suggests that it's possibly an issue with your proguard configuration (since Proguard is usually applied only on release builds).
Make sure you have
-keep public class * extends android.app.Activity
in your proguard file to ensure that the Activities are not obfuscated.

Please add this to your build.gradle at dynamic feature you create.
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

What worked for me was: remove all the tags <application> from the dynamic features' AndroidManifest and reunite all the Activities declarations on the application's AndroidManifest.
And before that I follow these migrations steps

I faced and fixed this issue. This problem arises, when you are not setting multiDexEnabled option correctly in your base build.gradle (app level) & the project itself.
defaultConfig {
...
multiDexEnabled true
}
And in dependencies
dependencies{
....
implementation "androidx.multidex:multidex:$multidex_version"
}
And you can extend your application class from MultiDexApplication
class YOUR_APPLICATION_CLASS : MultiDexApplication() {
// Rest of your code
}
In base app Manifest mention above application class like:
<application
android:name=".YOUR_APPLICATION_CLASS"
...
</application>
I paste less code for brevity.

Seems like you are missing it!

ClassNotFoundException when trying to put Android component into a library

I have two Android projects: an app and a library. The library uses StreamProvider and it is included as an AAR module in the app project. Here are important (changed by me) bits in both projects:
Library project:
AndroidManifest.xml:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="au.com.a1ict.mylib">
...
<provider
android:name=".provider.StreamProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="com.commonsware.cwac.provider.STREAM_PROVIDER_PATHS"
android:resource="#xml/file_paths"/>
</provider>
build.gradle:
repositories {
maven {
url "https://s3.amazonaws.com/repo.commonsware.com"
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:24.2.0'
compile 'com.commonsware.cwac:provider:0.4.3'
}
provider/StreamProvider.java:
package au.com.a1ict.mylib.provider;
public class StreamProvider extends com.commonsware.cwac.provider.StreamProvider {
public StreamProvider() {
}
}
App project:
AndroidManifest.xml:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="au.com.a1ict.myapplication">
app/build.gradle:
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:24.2.0'
compile project(':app-debug')
}
app-debug/build.gradle: (name chosen by Android Studio when importing the lib):
configurations.maybeCreate("default")
artifacts.add("default", file('app-debug.aar'))
settings.gradle:
include ':app', ':app-debug'
Compilation & linking phase ends up well, just when the app is about to start I see in the logs:

It must be related to the fact the component (StreamProvider) is located in the AAR file because when used in one project, it works flawlessly (same namespace, packages, ... -- I literally just copy library project's files into app-debug). Related SO questions mostly struggle with Eclipse. I'm really out of ideas here.

OK, this took one hell of an investigation but I have finally figured it out. It was actually a combination of several problems:
AAR doesn't contain information about its dependencies; so I either have to include them manually or setup a maven repository.
First I used maven-publish plugin for that only to realise it doesn't fill out AAR dependencies automatically.
Then I used Gradle Android Maven plugin, much better but:
Latest Gradle Android Maven plugin (1.5) requires Gradle 3.0+ while AS offers/recommends/sets 2.14.1 so I had to downgrade the plugin to 1.4.1
Then I realised that actually I still have to include https://s3.amazonaws.com/repo.commonsware.com dependency url into the app project because POM files do not contain information about repositories, only packages.
After that I finally don't see any crashes. Btw, I didn't have to use
compile ('com.group:artifact:0.0.1#aar'){transitive=true}
form (as suggested all over SO), specifying my dependency as:
compile ('com.group:artifact:0.0.1')
was enough.
