add ability to predex external libraries

[ezh]

Add ability to predex project dependencies with dxOpt (modified dxJavaOpt) This is allow preload external jars (like scala runtime) to android device. We're able to significantly reduce time to build apk at development stage.

Predex jar generated at classesDexPath / predex, also simple permission descriptor generated for /system/etc/permissions. Proguard must be switched off, of course.

After that we preload libraries at emulator or device and add something like that :-)

<uses-library android:name="slf4j-android-1.6.1-RC1" android:required="true"/>

to AndroidManifest.xml

Work flawlessly with Eclipse 3.7.1, ScalaIDE 2, scala 2.9.1, sbt 0.11.2

Add ability to filter predex libraries. This is allow to put some libraries(unstable) in classes.dex and other libraries hold as dex jars

For example, add dxOpts in Android := ("-JXmx512m", Some(Seq("./digilib."))) to push all . * /digilib. * in classes dex

Output for example (1st run): ...

So jar digilib_2.8.2-0.0.1.jar merged with classes.dex and all other libraries saved as pregenerated. Now we may upload it to emulator and use AndroidManifest.xml with

    <uses-library

        android:required="true" />
    <uses-library
        android:name="scala.library"

+1 for this

[saynomoo]

This is fantastic stuff! The patches does not however seem to merge to jberkel/master. I suppose the pull request should be updated

merged, thanks. would you mind adding some docs to the wiki?

[ezh]

Absolutely. Also I did mistake in code comments "prodaction" vs "production". So sorry. Please feel free to correct me, when necessary. I am not native speaker, so there are some glitches ;-)
