Re: [pygame] Pygame Subset for Android 0.9.2 Released

[René Dudfield <renesd@xxxxxxxxx>]

Hi again,

build_all.sh seems to have worked!

If you don't mind me asking questions... How do I know make it into an .apk that I can install?


Some notes...

I built python 2.6.4 from source, and copied the python and pgen from there into hostpython and hostpgen in the python source dir that's included in pgs4a.  

Then I needed to download the ndk 4b.  Which isn't listed on the android ndk website, so that took a bit of finding.  Aparently the newer SDL in git supports 5b... but the library hangs on anything below android 2.2 devices.

I had to fix a few instances for getattr in the pyrex, that used the third argument as a default argument.  I think the version that comes with ubuntu only works with 2 arguments.  I submitted a branch to merge a fix if you want it.

cya.

Hi,

last night I tried to compile pygame subset for android but run into my first error. 

Writing some notes here for referencing later...

It looks like the ndk r5b is different to r4b which is specified in the environment.
    http://developer.android.com/sdk/ndk/index.html

I changed the paths in environment.sh to the new places, but got an error after a while of building.

I am using 32bit ubuntu though, and I didn't compile python like you said.  So I'll try compiling python2.6.4 from source as hostpython and hostpgen like you say... and then if that still fails I'll try using the r4b ndk.

cya!

Do you build it on ubuntu?  If so, what packages do you need to install to package it?

Yes. From Ubuntu I grabbed the jdk and ant, while I downloaded the android-sdk and android-ndk directly from google.

 

If you're not using 64-bit ubuntu, you'll need to compile python 2.6.4 and copy the python and pgen binaries into Python-2.6.4 as hostpython and hostpgen, respectively. 

Is there a way to install it without the market?  My cheapo tablet doesn't have the market on it yet(without a hack), since it's still android 2.2, and apparently they're not supposed to put the market on 2.2 with 10 inch screens.  I guess I can just build packages which include pygame for people to download manually.

Two ways (both of which require you to enable "Unknown Sources" on the Applications Settings screen):

- You can just download the .apk file using the web browser, go into downloads, and choose it. That should install the app.

- Once you have the sdk set up, you can connect to the computer and run "adb install -r app.apk". (This also requires you to enable U

 

Is the web cam supported?  I'd guess not.  My device has one, so it'd be neat if it was working.  I wonder if we can use normal linux video interface (then we can use the code included in pygame already) or if we'd need to use some other API. 

I don't believe that the NDK supports accessing the camera directly. So we'd probably have to use JNI to access the camera.

 

What do you think of including other common game modules?  For example, numpy, pybox2d ( http://code.google.com/p/pybox2d/ ), pyaudio, etc.

Is there a chance to get ctypes working?  Or is that not possible with the python?

It probably makes sense to have a way of including these modules, if they can be cross-compiled. With the new model (where each application ships with its own copy of python and pygame), it probably makes sense to have a way for people to choose which modules should be included. That's what I'm doing with the Ren'Py-specific modules. 

 

At the same time, convincing Python to cross-compile is something of a challenge, since there isn't a supported way of doing so.
