private CaptureSessionFragment captureSession;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    this.captureSession = (CaptureSessionFragment) getSupportFragmentManager().findFragmentById(R.id.mob_capture_session);
}
<!-- activity_main.xml -->
<fragment android:name="bio.mobai.library.capture.CaptureSessionFragment"
    android:id="@+id/mob_capture_session"
    app:layout_constraintTop_toTopOf="parent"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    android:layout_height="200dp"
    android:layout_width="200dp"
    />
