I attempted a fresh install of everything on a newly brought up Arch system using the Beta 5.3.0:

http://www.mirrorservice.org/sites/download.qt-project.org/snapshots/qt/5.3/5.3.0-beta/2014-03-21_24/qt-opensource-linux-x64-android-5.3.0-beta_2014-03-21_05-03-20-21.run

.. I created a new project and from the project creation wizard I elected to setup the Android options (NDK/SDK/Java paths).

When I tried to run the project built for the kit "Android for armeabi-v7a on an armeabi-v7a Android-19 "Nexus 5" AVD, a dialog appeared containing:

"Select Android Device"

"Incompatible devices"

"AVD_for_Nexus_5_by_Google"
"ABI is incompatible, device supports ABIs: default/armeabi-v7a."

.. attempting to use the "Create Android Virtual Device" button resulted in another incompatible device being created.
