Android NDK usage

---

Hey there, I'm kinda new to android and coding in general, but I was wondering if someone could answer a few questions I had about the android NDK, preferably by someone that has actually used it.

1. How big of a performance boost could I get by using the NDK with a program that is currently runs slow due to a large amount of math processed each loop?

2. How hard is it to transfer data between the java and C/C++ code?

3. Is it possible to get input within the C++ code from the touch screen or keyboard?


Thanks, and sorry if this is the wrong thread for this, I wasn't sure where to put it.

i havent written anything with android yet but i have done java and c++ for a bit so i can tell you that for the most part, translating from java to c++ shouldn't be TOO difficult IMO
