Scala + Android Newbie

Question

I am trying to use the scala-andriod plugin and I am having a problem running and configuring AVD's. Im getting following errors from sbt

android:emulator-start NexusOne [success] Total time: 0 s, completed Nov 18, 2011 7:07:53 PM emulator: ERROR: This AVD's configuration is missing a kernel file!!

I have followed the direction on creating an avd but for some reason when I run the avd from sbt and android SDK manager I get that error.

Background: I used homebrew to install the sdk The .android folder containing the AVDs is in the default location mac home directory

Solution 1

On the Android SDK manager, install/reinstall "ARM EABI v7a System Image" and then create a new AVD.

Solution 2

Maybe it helps some people:

When running the "Android Virtual Device Manager". Clicking the Detail button, the AVD shows the AVD location on your system. Going to this directory will show you a config.ini file.

I changed the image.sysdir.1 value to something other in that particular file.

After going back to the AVD manager, it shows the virtual device with a repair option. Clicking the repair button wields something in the logs like:

[SDK Manager] Updated 'image.sysdir.1' with value 'add-ons/addon-google_apis-google-16/images/armeabi-v7a/'
[SDK Manager] Updated 'image.sysdir.2' with value 'system-images/android-16/armeabi-v7a/'

The thing to I noticed it added a image.sysdir.2 value. After this repair I can start the AVD without a missing kernel message.

This is purely an error on the side of Android's emulator -- it has nothing to do with Scala, or SBT. You can find the text of the error in this code, if you like.

So, I don't know what directions you followed when you created the AVD, but the AVD is malformed. Create a new one by running the android tool in the tools/ directory of the Android SDK, and then finding Manage AVDs... in the Tools menu.

(And to save you some time: after you have a good AVD, use android:package-debug to build an .apk, and android:install-emulator to move it into the emulator. You can do this while the emulator's running.)
