[Hoss3inf]

after migrating to androidx, the attributes that are related to app namespace does not work. otpView code:

 <com.mukesh.OtpView
                        android:id="@+id/edtOtp"
                        android:layout_width="wrap_content"
                        android:inputType="number"
                        android:layout_height="wrap_content"
                        android:textSize="@dimen/_16sdp"
                        app:itemCount="5"
                        style="@style/OtpWidget.OtpView"
                        android:cursorVisible="true"
                        android:layout_gravity="center"
                        app:lineColor="@color/colorPrimary"
                        android:gravity="center"
                        />

app ns: xmlns:app="http://schemas.android.com/apk/res-auto"
