imageview works only in Android Studio preview, but not on device or emulator

Issue

I've a problem with an image in an activity. For some reason the ImageView is visible in the Android Studio preview, but not when I build it on device or emulator. In any other activity it's working correctly. I'm not an expert in Android and I can't figure out what is the problem.

<?xml version="1.0" encoding="utf-8"?>

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

    <ImageView
        android:id="@+id/imageView2"

        android:layout_height="wrap_content"
        android:layout_above="@+id/map"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"

        android:layout_below="@+id/numeroRisultatiMappa"

    <Button
        android:text="@string/buttonhome"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

    <Button

        android:background="@drawable/my_button_bg"
        android:textColor="@android:color/white"
        android:textStyle="normal|bold" />


    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:id="@+id/numeroRisultatiMappa"

        android:textAppearance="@style/TextAppearance.AppCompat.Title"
        android:textSize="24sp"
        android:textAlignment="center"
        android:layout_toEndOf="@+id/buttonMapToHome"
        android:layout_toRightOf="@+id/buttonMapToHome" />


</RelativeLayout>

Any suggestion?

Solution

Please replace your fragment tag with below code.

<fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_above="@+id/buttonMapToHome"
        android:layout_below="@+id/imageView2"
        tools:context="MapsActivity"/>

And also in imageview please change app:srcCompat="@drawable/logo" to android:src="@drawable/app_logo"
