Image button icon not appearing on certain devices Android

Question

In my Android app I've added this Image button:

<ImageButton
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_play_circle_filled_black_24dp"
            android:background="@null"
            android:id="@+id/soundButton"

            android:layout_alignParentRight="true"
            android:visibility="visible" />

While testing on emulator and my nexus 4 it's working. But when I tried testing it on other phones, it just don't show up. Why?

You could try copying the image file to the app/src/main file. Android studio makes images of different sizes to fit different screens. What might be happening, as Juan Cruz Soler said, is that the image is too big to be displayed.
