Unhide GetJNIForThread

As an extension author I need access to Android's platform API. The obvious way to do this is through js-ctypes.

Hi Eitan, thanks for the patch. If you want to get review on the patch (which I assume you want), you should ask review on someone.
Comment 2 Eitan Isaacson [:eeejay] 2011-09-22 15:26:36 PDT
Hey Martijn. I assume you just set that flag right ("review?") for Doug. Right? Or do I need to do anything else? Sorry for the bmo newbyness!
Comment 3 Martijn Wargers [:mwargers] (gone per 2016-05-31 :-( ) 2011-09-22 15:31:28 PDT
Yes, I just set review for Doug. You don't need to do anything anymore.

this is fine -- but beware, i may change this symbol at anytime without warning. :-D

An alternative is to copy this function (all of it) into your support library.
Comment 5 Eitan Isaacson [:eeejay] 2011-09-22 15:57:47 PDT
Support library? wha?? I am hoping not to need one :)

Are we done with the review process? I could push it?
Comment 6 Martijn Wargers [:mwargers] (gone per 2016-05-31 :-( ) 2011-09-22 19:19:27 PDT
Yes, the review process id done. This can be checked in by someone who has check-in privileges (which is not you).
Ideally, you should make a mq patch, which includes your name and check-in comment (which at least should mention the bug nr):
- Add this in your .hgrc:
 [ui]
 username = First Last <email>
 [defaults]
 qnew = -U

- To edit the commit message of the patch:
hg qref -e

More info here (you also need to do some other stuff for the mq patch):

Thanks for the patch :-)

Folks stumbling across this bug via google search for "JNI" and "js-ctypes" might be interested in eeejay's gist which puts most of the pieces together: https://gist.github.com/1236179

I'm working on a patch to https://github.com/mfinkle/skeleton-addon-fxandroid to connect a few more dots for those looking to use Android ADK functions from a Firefox Mobile/Android extension.
Comment 9 Eitan Isaacson [:eeejay] 2012-09-06 14:40:33 PDT
Here is a more complete module:

https://github.com/cscott/skeleton-addon-fxandroid/tree/jni also has a more complete module.
