to fix this, use

xavante = require "xavante"
xavante.filehandler = require "xavante.filehandler"

yes, that's the plan!

thanks! no, we don't have any plans yet, but Swift + RAC should play well together, have a look at https://github.com/jspahrsu...

Re: How to preinstall Scala on your (rooted) Android phone

not sure if that would work since there is no way yet to compile code on the device itself .

Re: Scala on Android Revisited

Java is still the "lowest common denominator", there are a lot of Java devs around (compared to ObjC etc) so it makes sense for Google to push Java. But promoting Scala on Android would make the platform more interesting to a whole new group of developers.

Also I think Google suffers from the "not invented here" syndrome - they are more likely to come up with yet another language on the JVM to succeed Java (see Go for example, although not JVM-based).

Or they might go for a language which directly targets the dalvik VM - who knows.

do you mean this recommendation? http://developer.android.co...

20% performance difference sounds very optimistic - the recommendation in this document have been revised a few times since dalvik got JIT support.

i would do it the other way round - do everything in scala and use C (or Java, although the difference should not be that big) for performance critical sections. If you really want to add some static methods you can always throw in a Java class.

What do you mean by static references? While it is true that Scala itself does not use statics there is no problem accessing static fields from existing Java code.

IntelliJ IDEA has this concept of facets - you can use both Scala + Android in the same project, works quite well. Not sure about Eclipse.

Re: Scala: A Better Java for Android

Some assumptions Scala makes (e.g. object creation and garbage collection are fast and cheap) are not necessarily valid on the dalvik VM. Scala's focus on immutable data structures implies that a lot of objects get created which might slow things down on Android where you usually try to avoid creating too many objects since memory is more limited and the GC is slower.

For normal apps this is normally not an issue though, and the dalvik VM is still being improved (concurrent GC, better JIT etc).

@Guest: Scala "defaults" to immutable data structures but you can also use mutable ones. For example, try out the following in the Scala shell:

scala> Map(1->2)
res0: scala.collection.immutable.Map[Int,Int] = Map((1,2))

There's also a corresponding "scala.collection.mutable.Map".

You should be able to upload tracks from third party apps to SoundCloud with the Android app. Just select "Send" from the context menu, and pick "SoundCloud" (application specific, but should work with filemanagers and such).

you could store the png somewhere and then link to it i guess - but it wouldn't be dynamic.

In the meantime i've released 0.5.1 which means you shouldn't need to change version numbers in the file.

sure, it would be great to integrate this with ACRA. do you have a project mailing list ?

yoda: hmm, maybe bundler is set up to ignore shared system gems (and the environment is locked), in which case you'd need to add a dependency to interactive_editor in your Gemfile.

Thanks for the report, looks like some weirdness on osx. I just published 0.0.3 which fixes the problem.

Re: Building Android apps in Scala with sbt

jberkel — Mon, 08 Mar 2010 03:47:22 -0000

hi sciss,

sbt (by design) doesn't use your local scala installation, instead it'll automatically download the version it requires. to use scala 2.8, edit project/build.properties and change build.scala.versions to "2.8.0.Beta1", then run "sbt clean update package-debug". When building it should display "[info] Building project foo 0.1 against Scala 2.8.0.Beta1". hope this helps.

Re: Building Android apps in Scala with sbt

jberkel — Mon, 01 Mar 2010 13:23:22 -0000

just released 0.4.1 which should work ok with newer versions of sbt (also updated instructions on this page, which still mentioned 0.5.6).

i've just pushed some changes which will always reinstall before running tests, which is the expected behaviour.

Re: Building Android apps in Scala with sbt

jberkel — Mon, 22 Feb 2010 07:49:00 -0000

UnitTests.scala is actually more like an integration test (it runs on the device/emulator). UnitTests will always pass, unless you change it to make it fail. at the moment test-emulator won't reinstall the test package, you'll have to do that manually (sbt 'project tests' install-emulator). this should probably be changed.

i'm not sure, but it might be one of the android tools writing to stderr instead of stdout (which will get flagged as [error]). this is confusing but can be ignored. is the package building ok?

Re: Building Android apps in Scala with sbt

jberkel — Mon, 01 Feb 2010 07:39:11 -0000

haven't had the need to debug my apps, but will give it a try & let you know.

Re: Building Android apps in Scala with sbt

jberkel — Mon, 01 Feb 2010 05:45:07 -0000

your debug problems are very likely not scala specific, as there's no difference at bytecode level between the two languages.

should be trivial to do add: the syntax is "am start -a android.intent.action.MAIN -n
com.example/com.example.Foo". just add an entry to the github issue tracker.
