Python for Android
2+
==================
3+
4+
Python for android is a project to create your own Python distribution
5+
including the modules you want, and create an apk including python, libs, and
6+
your application.
7+
8+
In terms of comparaison, you can check how Python for android can be useful
9+
compared to other projects.
10+
11+

| Project | Native Python | GUI libraries | APK generation | Custom build |

15+
| PGS4A | Yes | Yes | Yes | No |

17+

20+
21+
Prerequisites
22+
-------------
23+
24+
WARNING: the current version is working only on Ubuntu oneiric (11.10). We
25+
don't provide support on other platform. If it doesn't work, send us patch, not
26+
bug report.
27+
28+
You need the minimal environment for building python. Note that other libraries
29+
might need other tools::
30+
31+
sudo apt-get install build-essential patch
32+
33+
You must have android SDK and NDK. You can download them at::
34+
35+
http://developer.android.com/sdk/index.html
36+
http://developer.android.com/sdk/ndk/index.html
37+
38+
If it's your very first time into android sdk, don't forget to follow
39+
documentation for recommended components at::
40+
41+
http://developer.android.com/sdk/installing.html#which
42+
43+
You need to download at least one platform into your environment, so
44+
that you will be able to compile your application and set up an Android
45+
Virtual Device (AVD) to run it on (in the emulator). To start with,
46+
just download the latest version of the platform. Later, if you plan to
47+
publish your application, you will want to download other platforms as
48+
well, so that you can test your application on the full range of
49+
Android platform versions that your application supports.
50+
51+
After installing them, export both installation path::
52+
53+
export ANDROIDSDK=/path/to/android-sdk
54+
export ANDROIDNDK=/path/to/android-ndk
55+
56+
# examples
57+
export ANDROIDSDK="/home/tito/code/android/android-sdk-linux_86"
58+
export ANDROIDNDK="/home/tito/code/android/android-ndk-r5b"
59+
60+
61+
Usage
62+
-----
63+
64+
Step 1, compile the toolchain::
65+
66+
MODULES="openssl pygame" ./configure.sh
67+
68+
Step 2, package your application::
69+
70+
...
