图片显示在预览中，但不在Android平板电脑上显示。 XML问题？

Question

So I have been working on an Android application to make an application for use with DJI's consumer level drones. I have been making the user interface and using XML throughout the project with no issues. I want to add a .png to the UI just so that my logo is showing. When I preview it in Android Studio, I can see the logo being shown but when it is run on the tablet, it is not there. Everything else using XML is fine though. I even preview using the same resolution/ screen size as my tablet I am using (cheap Hudl 2 tablet).

If anybody has any ideas about how I can get this to work, I would appreciate it. I have shown my university lecturer it and he couldn't give me an answer too as nothing seems to be out of the ordinary.

Android studio preview

<ImageView
    android:id="@+id/imageView2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:srcCompat="@drawable/macrosfordji"
    android:layout_alignParentTop="true"
    android:layout_alignParentEnd="true" />

Answer 1

Try this (android:src="..." instead app:srcCompat="..."):

<ImageView
    android:id="@+id/imageView2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/macrosfordji"
    android:layout_alignParentTop="true"
    android:layout_alignParentEnd="true" />
