Does anyone know how to use Room in an Android Library without having to include any reference to Room in the Android (Java) app?
It's probably useful to note that I'm including a built .aar file of the Android Library in the libs folder which is then referenced by the Android App application level build.gradle. The Android Library and Android App have no connection to each other, other than through the compiled .aar file.
Here's what I'm basically doing:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
MyCustomLibrary.storeSomething("The thing to store"); //method that calls Room stuff
}
The storeSomething method works as expected if I include Room in the app itself, and throws the following if I exclude it:
java.lang.NoClassDefFoundError: Failed resolution of: Landroid/arch/persistence/room/RoomDatabase;
My goal is to not have the app know anything about Room.
See below for all the build.gradle files.

I attached my app and project level gradle file.
My Android is work fine in Android Studio 3.0.1 , but it show the follow build error after I update to the Android Studio 3.1.
Could not find android-maven-gradle-plugin.jar (com.github.dcendents:android-maven-gradle-plugin:2.0).
Searched in the following locations:

Did I missing something ? Thanks in advance.
After I update the following , the project work fine.
Update
classpath 'com.android.tools.build:gradle:3.0.1'
to
classpath 'com.android.tools.build:gradle:3.1.0'
And Update
classpath 'com.github.dcendents:android-maven-gradle-plugin:1.5'
to
classpath 'com.github.dcendents:android-maven-gradle-plugin:2.0'
also update the gradle-wrapper.properties to
