i wanted to try at least a "hello world" on android.
so i installed some linux on a usb stick to use as a
"mobile development environment". it went rather well,
using the official hello world tutorial, eclipse and ADT.
but eclipse is not my thing really and as many components
needed for android development run on openbsd, and there
is linux emulation (must be on for this) i started
wondering how far could i get on openbsd before using
linux as a crutch.
turns out, looong way.
the development flow is basically: write code, make apk,
install apk on phone/emulator, run apk, (get rich).
first things first, had to cheat to get the SDK. the
initial download android-sdk_r16-linux.tgz contains
only scaffolding to get the real thing. it is in java,
but unfortunately swt (part of eclipse) from ports is
too old and i couldnt use the GUI or install ADT (Android
TODO: try to update the eclipse port.
but as i already had all of it on the linux stick,
i simply rsync-ed it over under ~/adroid-sdk
$ ls -1 android-sdk
$ sudo pkg_add jdk apache-ant
$ export PATH=$PATH:/usr/local/jdk-1.7.0/bin:$HOME/android-sdk/tools:$HOME/adroid-sdk/platform-tools
$ java -version
openjdk version "1.7.0"
OpenJDK Runtime Environment (build 1.7.0-b00)
OpenJDK Server VM (build 21.0-b17, mixed mode)
apply the attached patch to dx.
these are the API's i have installed using linux:
$ android list target | grep ^id
id: 1 or "android-3"
id: 2 or "Google Inc.:Google APIs:3"
id: 3 or "android-7"
id: 4 or "Google Inc.:Google APIs:7"
id: 5 or "android-15"
id: 6 or "Google Inc.:Google APIs:15"
i will use id 3 (Android 2.1.x Eclair)
HelloAndroid.java is also attached
$ cd src/android/hello
~/src/android/hello$ android create project -t 3 -n HelloPuffy -p . -k com.puffy.hello -a HelloPuffy
~/src/android/hello$ cp ~/HelloAndroid.java src/com/puffy/hello/
~/src/android/hello$ ant debug
if i did not leave out something, the output should finish with:
Total time: 7 seconds
for now i upload the apk files using ftp (swiftp on android). http://obiit.org/f/hello.png
obviously, this is a suboptimal solution, and there is the emulator...
let's see how far that goes.
~/src/android/hello$ android create avd -n puffy_avd -t 3
Auto-selecting single ABI armeabi
Android 2.1 is a basic Android platform.
Do you wish to create a custom hardware profile [no]
Created AVD 'puffy_avd' based on Android 2.1, ARM (armeabi) processor,
with the following hardware config:
unfortunately 'emulator' uses /proc to determine
it's own path, so we need to trick it:
~/src/android/hello$ sudo ln -s ~/android-sdk/tools/emulator /proc/self/exe
~/src/android/hello$ emulator -avd puffy_avd
emulator: ERROR: _camera_device_open: Cannot open camera device '/dev/video0': No such device or address
emulator: warning: opening audio input failed
emulator: WARNING: Unable to create sensors port: Connection refused
masaka! stupefaction http://obiit.org/f/android-emulator-on-openbsd.jpg http://obiit.org/f/android-emulator-on-openbsd2.jpg
and its fast compared to the linux stick. just wow.
now the bad news. adb does not work.
i have asked about it some time ago on ports@
as having a native adb just by itself would be
great to push apk's, shell, root, etc. http://marc.info/?l=openbsd-misc&m=131809077812364&w=2
some responses indicated it's already work in progress.
TODO: get adb to work
adb source: https://github.com/android/platform_system_core
so this is it, perhaps because i started out with zero
expectations, this is a massive happy end.
of course, hello world is just that. it remains
to be seen if more complicated projects can be
most days the only good thing on tv is the vase.
