0.7 Snapshot

[fxthomas]

I've been using this branch for a few weeks now to create a small app that I will publish on the Play Store soon, and I believe it is stable enough to be pushed to master. If you find anything bad, let me know!

See the tutorial for a more complete overview on how to use the plugin, and see the posts on the mailing list for some bugs and issues that have been ironed out.

[jberkel]

quite a big PR, but looks good. would also be good to have an updated g8 template to use with with 0.7-SNAPSHOT, didn't find any on your github repo.

[fxthomas]

Ah, yes, the g8 template is not up-to-date, thanks for reminding me! I'll push a commit as soon as I can to change that. In the meantime, fxthomas/android-scratch is a dead-simple example for a small project.

The request is pretty large indeed -- I was hoping to submit more often, but my first commits were a little experimental and weren't very interesting by themselves, so I ended up rebasing them when I pulled from the 0.6.4 release.

Anyway, the large bulk of my improvements is in the first commit. The next commits are mainly bug fixes thanks to the feedback I got on the list.

I tried your android-scratch project, but I get the following exception when trying it in the emulator:

@MHOOO : Which OS? Are you using the project out-of-the-box or did you make changes? Can you run show sources and tell me what's inside it?

I just tried it, and it definitely works for me - I'm on OSX 10.7, Android SDK r22.0.1, not sure if this is relevant.

[fxthomas]

@jberkel : PR sent to the Giter8 template!

[MHOOO]

@fxthomas Out-of-the-box project without any changes made to it. I am running Ubuntu 12.10, android-sdk_r22.0.1-linux and OpenJDK 1.7.0_21. The command "show" does not exist on ubuntu. What does it do? Maybe I can find an alternative.

[fxthomas]

@MHOOO : Sorry about the late answer. show is not an Ubuntu but an SBT command, which you can run in the SBT console.

Can you describe the steps you used to build the app?

[MHOOO]

I did everything as described in the readme, nothing else. Here's how I got it to work though: I added the following line to the build.sbt

proguardOptions += "-keep class com.scratch.**"

Turned out proguard simply removed the R class.

[MHOOO]

@fxthomas Just making sure you get notified of above message (forgot to @ you)

[fxthomas]

Could you maybe post the contents of the ProGuard configuration? They are saved under target/scala_2.10/src_managed IIRC.

R.java should be automatically included when generating the resources, but there could be something I overlooked.

[MHOOO]

@fxthomas I have made additions to the proguard configuration options, so its grown larger than initially. But I think this should still help to track the issue. target/scala_2.10/src_managed/proguard.txt: https://gist.github.com/MHOOO/61aaddaf22bb26e63c65 build.sbt: https://gist.github.com/MHOOO/94ae783284c690414648

[fxthomas]

Does it still crash if you remove all the extra dependencies?

Did you try removing the target/ directory entirely before rebuilding?

[MHOOO]

I checked out the project again, but did not get the error this time. I've had a similar problem (some files missing) while trying to compile akka for android and the solution there was to switch to java 1.6 (from java 1.7). Turns out I still had java 1.6 active, which is why it worked with the clean checkout. So, the problem came about from using java 1.7 instead of java 1.6.

[fxthomas]

So maybe we need to set the target to Java 6 by default in the plugin? I'll add that when I can!

[jkremser]

I had the same problem with Java 7, after switching to Java 6 it was OK.

[appamatto]

I merged this request. Awesome work, @fxthomas! It's too much to review carefully but we'll be able to address issues as they come up. Thanks!

[fxthomas]

Thanks! As far as bugs are concerned, I will fix them whenever I can, of course!

FYI, I am going to keep on using the plugin to run an app we're developing at work from. I'm not directly working on the app itself, and it's pure Java (no Scala :( ), but 10 minutes here and there should be enough to ensure that sbt-android at least handles it correctly.

Anyway, glad to see it go live! ;)
