Extend android.make so that it can generate a debug signed apk.

'make && make apk && adb install -r bin/Rockbox.apk' should work now.

You should now be able to develop without eclipse.

 Use this as your build folder, using '../tools/configure' etc.
-    $ ../tools/configure
+    $ ../tools/configure # type 200, then chose A for android and your screen resolution
     $ make
 
-After the build finished, you need to copy librockbox.so to libs/armeabi/ (create that dir if it doesn't exit)
+After the build finished, you can create a Rockbox.apk in bin/
-    $ mkdir -p libs/armeabi
+    $ make apk
-    $ cp librockbox.so libs/armeabi
 
-For the other files (codecs, themes), you execute 'make zip'. Then you copy the

-    $ make zip
-    $ cp rockbox.zip libs/armeabi/libmisc.so
-
-rockbox.zip..err, libmisc.so will be unpacked at runtime.
-
-To finish, you can follow this guide [3], or use eclipse. Simply install eclipse
-and the android plugins, then import this folder as a new Android project and run it.
-See [4] for a guide on how to set up eclipse for android development.
 
 
+NOTE: make apk needs creates a debug signed .apk, not suitable for distribution.
+It expects that this key already exists.
+You should be able to generate it with "keytool" using the following options:
+* Keystore name: "debug.keystore"
+* Keystore password: "android"
+* Key alias: "androiddebugkey"
+* Key password: "android"
+* CN: "CN=Android Debug,O=Android,C=US"
+* validity: 365 days
+
+Google docs mention the SDK tools can generate it as well, but I haven't found how yet.
