Move this to where you declare cc_delegate below since you don't use it in these
first few lines.

[please use gerrit instead, 2016/01/08 00:07:05]

Done.

Hopping back and forth across the JNI barrier can get very expensive.  How many
times do you expect this to loop, on average?  Does it make sense to pass java
arrays, instead (see base/android/jni_array.h)?

[please use gerrit instead, 2016/01/12 00:47:25]

I expect the outer to loop 1 time. inner: 2 times. Probably not worth it to pass
arrays. What do you think?
