Reading up more on adding the API to Android..is it correct that I'd
essentially be building a SDK Add On? If so, I've been reading about
the files present at
http://android.git.kernel.org/?p=platform/vendor/sample.git;a=tree and
following that guide, I've created the frameworks, and sdk_addon
directory in addition to my <product> directory that already existed
to build Android for my board.
I added the sample_addon.mk file to my <product> directory and then
added that to <product>/AndroidProducts.mk file.
Looking at the readme.txt file in the link above, it says to use:
make -j8 PRODUCT-sample_addon-sdk_addon
So do I literally use the word PRODUCT here, or my product name or
what? If I use PRODUCT, then it builds a Generic SDK? Is that what I
want? The lack of documentation around this is seriously
frustrating..having to google for days to get random snippets of
information and try them out is so painstaking..
Any and all help would be appreciated..
