We need to add these lines to build.gradle file (in-app module)

defaultConfig {
     …// Support for vector drawable.
     vectorDrawables.useSupportLibrary = true// Add if other libraries have more architectures.
     ndk {
         abiFilters "armeabi-v7a”, "arm64-v8a"
         // Supported "armeabi-v7a”, "x86", 'x86_64', "arm64-v8a"
     }
 } 
 // We are using 8 JavacompileOptions {
     sourceCompatibility JavaVersion.VERSION_1_8
     targetCompatibility JavaVersion.VERSION_1_8
 }

Needed for correctly selecting supported architectures.

We support:’armeabi-v7a’, ‘x86’, ‘x86_64’, “arm64-v8a”. There are no known devices running x86_64 only emulator so it can be excluded from the final build. To lower size, you can remove x86 support, in theory all x86 devices should support Armv7 with around 30% hit to performance, there are exotic devices which possibly don’t support this “arm64-v8a” and ‘armeabi-v7a’ will be mandatory by google play store from 2019 August to be included to .apk or bundle.

In the manifest file, the below permissions and features should be added.

<!-- Required for capturing document, selfie and Proof Of Address images -->
<uses-permission android:name="android.permission.CAMERA" />
 
<!-- Required for communication with IDscan enterprise onboarding service -->
<uses-permission android:name="android.permission.INTERNET" />
 
<!-- Permission used for liveness action changes if not added we will not vibrate on action change. -->
<uses-permission android:name="android.permission.VIBRATE" />
 
 
<!-- Camera features - recommended -->
<uses-feature
    android:name="android.hardware.camera"
    android:required="true" />
<uses-feature
    android:name="android.hardware.camera.autofocus"
    android:required="false" />
<uses-feature
    android:name="android.hardware.camera.flash"
    android:required="false" /> 

SDK should be initialized before using any SDK function. You can either initialize before using directly (lazy) or while application/activity creation.

MJCS.init(context); 

Kotlin

MJCS.init(this@YourActivityActivity) 

Please note: SDK initializing takes a few seconds. Hence it should not be called on the UI thread as IO operations are happening.
