Rockbox as an application: Commit current Android port progress.
General state is: Rockbox is usable (plays music, saves configuration, touchscreen works too). Problems: - Playing music in the background (i.e. when switching to another app) doesn't work reliably, but I'm working on that now. - no cabbiev2 (only some preliminary files for it), no other default theme. - screen flickers sometimes if the updates are too frequent - no multi screen apk/package - strange behavior when a phone call comes in The java files (and the eclipse project) resides in android/, which is also supposed to be the build folder. I've put a small README in there for instructions. There are some steps needed after the make part, which are described there, and which eclipse mostly handles. But there ought to be some script/makefile rules which do that instead in the future. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27668 a1c6a512-1295-4272-9138-f99709370657

+This folder contains the java parts needed to build an Rockbox as an
+application for android.
+
+* Build instructions
+
+Until there's a script which does all the work the procedure is documented here.
+
+First, make sure you have the ANDROID_NDK_PATH environment variable set up,
+otherwise configure will fail to find the compiler.
+
+Use this as your build folder, using '../tools/configure' etc.
+ $ ../tools/configure
+ $ make
+
+After the build finished, you need to copy librockbox.so to libs/armeabi/.
+ $ cp librockbox.so libs/armeabi
+
+For the other files (codecs, themes), you execute 'make zip'. Then you copy the
+zip to libs/armeabi, using the name libmisc.so. This is needed, since there's no
+way to bundle stuff into apk's and have access to them from native code other
+than pretending it was a library.
+ $ make zip
+ $ cp rockbox.zip lib/armeabi/libmisc.so
+
+rockbox.zip..err, libmisc.so will be unpacked at runtime.
+
+To finish, you can follow this guide [1], or use eclipse. Simply install eclipse
+and the android plugins, then import this folder as a new Android project and run it.
+See [2] for a guide on how to set up eclipse for android development.
