Hello! I have developed an app that use the org.opencv.android.JavaCameraView. My problem is that if I run the application in Asus P00C (10' ) it works well (the camera view is full screen). If I run the application in a SAMSUNG SM-T713 (8') the camera does not cover the entire display. In this case though, the application works in full screen because a textview compare in the black part of the screen where the camera view does not arrive.

This is the xml code:

** <android.support.constraint.constraintlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:opencv="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="underwater.sapienza.com.markerrecognition.MainActivity">

    android:layout_width="wrap_content"

    />

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    >

    android:text="DIMINUISCI SOGLIA MINIMA" />

<TextView
    android:id="@+id/textViewSogliaMinima"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"

    />
