Group: Hardware/History/Howto have a free android sdk

Update

aaronw in #libreplanet found that: http://code.google.com/p/android/issues/detail?id=1261

Rationale

A free SDK could permit us to develop free applications for the androids phones such as a replacement for non-free applications that runs on the androids phones such as the market

Documentation on howto compile it

The problem is that with the JDK6(icedtea is a JDK6) we get that error:

$ make sdk

Docs droiddoc: out/target/common/docs/dx
javadoc: error - In doclet class DroidDoc,  method start has thrown an exception java.lang.reflect.InvocationTargetException
com.sun.tools.javac.code.Symbol$CompletionFailure: class file for sun.util.resources.OpenListResourceBundle not found
1 error
make: *** [out/target/common/docs/dx-timestamp] Error 45

According to the search engines it's not specific to my target but it's a classic error when someone doesn't have the old non-free java5 version

My first try was to try to add the missing class:

so I added the class in /home/android/koolu/build/tools/droiddoc/src

cd /home/android/koolu/build/tools/droiddoc/src
mkdir -p sun/util/resources/
cp ~/errors/OpenListResourceBundle.java sun/util/resources/

And I modified the Android.mk like this:

LOCAL_SRC_FILES := \
+     sun/util/resources/OpenListResourceBundle.java \

while it compiled the class and added it where it should do it didn't work and I had the same error(I didn't understand if it came back later or if the build process had rebuild more things before failing)

Then I tried to add :

LOCAL_DROIDDOC_USE_STANDARD_DOCLET := true

in /home/android/koolu/buildspec.mk It didn't worked...so I did something ugly:I added it to the top of this file instead:

/koolu/build/core/droiddoc.mk

and it passed the error with a lot of warnings

How/Why it works

here's the interesting part of the Makefile

Basically it make use of the standard doclet instead of android's doclet
