[syphyr]

@n8fr8 @bitmold I have found a few bugs in the additional JNI methods added to Tor for Android.

syphyr/tor@e68d4ad
syphyr/tor@d459a7d

Has anyone had the chance to review this yet?

[bitmold]

@uniqx could you please take a look at this. especially the commit changing return -1 to return false. @uniqx is the person who maintains the fork of C tor used in this project

[syphyr]

@uniqx Do these changes look ok to you?

[uniqx]

Sorry I must have missed the initial ping, yes looks perfectly fine to me 👍

[bitmold]

@uniqx could you please be able to merge this with a new build of tor 0.4.8.20
