On dalvik System.getProperty("os.arch") returns "armv7l" on my Galaxy S4 mini and is therefore not detected as an embedded platform.

Changing this line in EnsembleApp
   public static final boolean IS_EMBEDDED = "arm".equals(OS_ARCH) && !IS_IOS;
to
  public static final boolean IS_EMBEDDED = OS_ARCH.startsWith("arm") && !IS_IOS;

and this line in PlatformFeatures
    private static final boolean ARM = arch.equals("arm");
to
    private static final boolean ARM = arch.startsWith("arm");

fixes the problem.
