I tried changing CPU to use generic-armv7-a which is one of
the "valid" arguments according to above message. That gives
the same error, but this time not even displaying the list of

ndk is android-ndk-r13b <br>

Any suggestions? <br>

Thank you, it now builds and installs on my 32-bit tablet. However
it does not run.<br>

Some internet links about this -<br>
<br>
<i>For those stumbling onto this thread while having trouble with
srand/atof on NDK r10c: Make sure you set your android target to
19. Your app should then work on Android 5 (21) as well as all
lower versions.</i><i><br>
</i><br>
<i>if i use Android 19 to compile the codes that invoke srand(),
because srand() is a static inline function, so it will invoke
srand48 instead, which means cocos2d-x depends on srand48
instead of srand. srand48 is defined in all Android versions, so
there is not problem.</i><i><br>
</i><i>i using Android 21+ to compiling the codes, srand() is
defined like void srand(unsigned int);, so cocos2d-x depends on
srand. Because srand is not defined below Android 21, so it will
have problem if running on Android version below 21.</i><i><br>

My tablet has android 4.2.2, which should be ok with api version
21, I would think.<br>

Ah 4.2.2. <br>
<br>
I have a "special" build mode.<br>
<br>
./makelibs.sh --oldarm all<br>
./mythbuild --oldarm<br>
<br>
It did work for me for 4.2.2 and 4.4 like my projector and my TV. 32
bit only build too.<br>
<br>
I just noticed that there may be some inconsistencies between
makelibs and mythbuild for ANDROID_NATIVE_API_LEVEL.<br>
That may (or not) need to be resolved.<br>
<br>
Also this is untested with newer lib additions as yet.<br>
