I've some ImageViews in my application. They show up fine on my phone but there's no way to show them on an emulator. I've already tried different version and screen size. In another questions people where able to solve the problem using android:hardwareAccelerated="false" or using src instead of srcCompat, but nothing of this seems to help.
The ConstraintLayout where imageViews are:
<android.support.constraint.ConstraintLayout
android:id="@+id/login_header"
android:layout_width="0dp"
android:layout_height="wrap_content"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent">
<ImageView

I don't think that my layout structure is the problem, but maybe you could prove me wrong. Images show on phone with API 24 Nougat 7.0. I tried emulators from API 21 to 23 because my minimum API is 21.
