Building for Android on Linux (Ubuntu 12.04 64bit)
CAVEAT
This guide is written from the perspective of a first-time Linux user to describe the steps I took to publish to Android from Linux and help other Moai users by describing problems I encountered. If any of the information I give here is wrong or misleading, please feel free to correct, clarify or add missing information.
I assume that you already have the MOAI SDK and a working Linux-host.
- Android NDK
- Android ADT Tools
- JAVA SE 6 or 7
- lib32z1
- lib32ncurses5
- lib32bz2-1.0
- libstdc++6:i386 (for adb to work)
(I am not sure if all 4 of those are required, but without them, android build failed for me)
- MOAI_BIN ("bin" directory of the Moai SDK for your platform, e.g.: export MOAI_BIN=/home/user/moai-dev/release/linux/host-sdl/x64/bin)
- MOAI_CONFIG (directions to a Moai config, e.g.: export MOAI_BIN=/home/user/moai-dev/samples/config/)
- ANDROID_NDK (directions to the build folder of your android ndk, e.g.: export ANDROID_NDK=/home/user/android-ndk-r9d/)
Set them as persistent environment variables as described here:
https://help.ubuntu.com/community/EnvironmentVariables#Persistent_environment_variables
Install your Android target platforms using the Android sdk manager.
I think that Android-10 is always required, but I could be wrong.
You should now be able to create your Android host with ./bin/build-android.sh
./build-android.sh: line 3: /home/user/.bash_profile: No such file or directory
To my knowledge, this can be ignored.

If build-android.sh is giving you "permission denied" errors like in the example above: in my case, build-android.sh always failed while the Android NDK was stored on another partition (e.g. a shared partition between Windows and Linux). Simply changing permissions on the NDK folder did not suffice, but moving the Android NDK to the main Linux partition fixed it.

Check if the path in your ANDROID_NDK environment variable is correct. If it is, those "not found" errors as in the example above can happen if you are missing some 32-bit libraries: see "SETUP" above for a list of the required libraries.
If adb fails because of a missing library:
error while loading shared libraries: *name of library*
Install it and please add the name of the library to the list under "SETUP" above.
