Did you install the Android SDK / JDK, etc? If not, start here - http://developer.android.com/sdk/index.html.
If you're running 64-bit like me, make sure to install the ia32-libs, since the SDK is 32-bit.
This is completely based on the Hello Android tutorial - I didn't really do a whole lot, but the hope is that this will help get some more ruby devs into android development with a simple how-to.
Step 1 - Setup RVM with jruby
Note: RVM is awesome, if you don't use it or don't know about it - read more here.
rvm install jruby cd /path/to/your/android/pindah/mirah/project/dir/ # using your .rvmrc will trigger `rvm use jruby` when you cd into your project dir. echo "rvm use jruby" > .rvmrc # this will make sure your .rvmrc is working, you should then be able # to use rvm info and see jruby cd .
Step 2 - Install the mirah and pindah gems
# too easy gem install mirah pindah
Step 3 - Create your first pindah app
pindah create com.example.android.hello_world cd hello_world
Step 4 - Create your activity - HelloAndroid.mirah
# from your project dir and inside your pindah app dir <editor> src/com/example/android/hello_world/HelloWorld.mirah
This is the code I used:
Step 5 - Setup your AndroidManifest.xml file
This is where you define your app, version, name, etc, but more importantly for this example - what activity will handle your main intent.
Mine looks like this:
Step 6 - Install to your device
# make sure a device is recognized ... # and make sure adb is in your path (platform-tools in the SDK) adb devices rake install
