Android compatibility issue with many devices

I have followed the instruction on
http://jogamp.org/wiki/index.php/Android_Packages

but unfortunately for some devices (for example the Galaxy Mini) the only downloadable packages are Launcher and Test, cannot download

    GlueGen
    JOGL

from google play

What about this problem?

Hi

Galaxy Mini is shipped with Android Froyo 2.2 whereas JOGL requires at least Android 2.3 as far as I know. Best regards.

We have lowered the default optimization level for the latest jogamp jogl android builds from armv7 to armv6 to stay compatible with more devices. We are still testing if you want to help out then get the latest android APK files here:
http://jogamp.org/deployment/archive/master/gluegen_600-joal_366-jogl_833-jocl_691-signed/apk/
This will eventually become rc11 when we find no more obvious bugs.
Report any failures to the following thread:
http://forum.jogamp.org/Pls-test-new-JOGL-aggregated-build-pre-RC11-no-XInitThreads-tp4026312p4026493.html

As long as your phone is shipped with stable OpenGL ES 2 drivers makes JogAmp able to support it.
The armv6 android builds is in theory binary compatible with the Galaxy Mini, please test.

Xerxes, if his Galaxy Mini is shipped with Android 2.2, it won't work anyway, am I wrong?

You are correct.
To quote Sven from IRC:
(2012-10-14 06:50:47) sgothel: Julien is right, currently 2.3 is minimum requirement :(
(2012-10-14 06:51:04) sgothel: this is due to the native Surface API, introduced w/ 2.3
(2012-10-14 06:51:58) sgothel: < 2.3 had something similar, but would require a 2nd code path

Thus some additional work is needed to support the 2nd code path on < 2.3.
It can be done but nothing that we support right now.

There is some people who have managed to get android 2.3 running on the galaxy mini. Do someone know if these updates is rolled out by Samsung or by a third party?

Keep in mind that most manufacturers have better to avoid providing these updates in order to encourage planned obsolescence so that their customers have to buy new hardware more frequently instead of updating only the "software". In France, it is quite difficult to obtain updates except on models directly handled by Google.
