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

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

Hi Mark<br>
<br>
--oldarm successfully compiled and installed after a couple of
tweaks.<br>
<br>
Now it fails with <br>
<br>
D/dalvikvm( 9979): Trying to load lib
/data/data/org.mythtv.mythfrontend/qt-reserved-files/plugins/platforms/android/libqtforandroid.so

found <br>
<br>
I checked, libfreetype.so does exist in
/data/data/org.mythtv.mythfrontend/lib/<br>
It is the correct file type<br>
peter@andromeda:~$ file
'/home/peter/proj/github.com/MythTV/packaging/android/mythinstallold/libs/armeabi-v7a/libfreetype.so'<br>
/home/peter/proj/github.com/MythTV/packaging/android/mythinstallold/libs/armeabi-v7a/libfreetype.so:
ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV),
dynamically linked, interpreter /system/bin/linker, stripped<br>
<br>
Perhaps it is supposed to be in directory
/data/data/org.mythtv.mythfrontend/qt-reserved-files/plugins/platforms/android/
where that libqtforandroid.so is found.<br>
<br>
Adding to my confusion is the fact that in the apk we do not
deploy a file called
qt-reserved-files/plugins/platforms/android/libqtforandroid.so
- we actually deploy
lib/armeabi-v7a/libplugins_platforms_android_libqtforandroid.so
and by some magic it maybe gets renamed and moved, or possibly
just linked.<br>
<br>
On android the file
/data/data/org.mythtv.mythfrontend/libplugins_platforms_android_libqtforandroid.so
exists and can be listed.<br>
I am unable to list
/data/data/org.mythtv.mythfrontend/qt-reserved-files/plugins/platforms/android/,
I get Permission denied.<br>
<br>
If you don't know what is going on here, no worry this is not
important, just something I am trying for interest and
learning.<br>
</blockquote>
On android you cant have a deep lib directory. I has to be
shallow/flat. So I came up with the above flattening schema to
allow plugins to be distinct (also filters).<br>
However freetype should be there since it's build and deployed.<br>
I havent build oldarm for a while esp. since the external lib
refactor. Ill investigate.<br>
<br>
Note: I am learning too. I haven't done much of importance/large
with android except this. If it looks like I know what I'm doing
then I've pulled the wool over your eyes well.<br>

<br>
I did have to remove "android:banner="@drawable/banner" from the
Manifest to get it to create the package with --oldarm<br>
See attached patch.</blockquote>
Good solution. Commit it.<br>
