[android-developers] Re: Android data buffer pass by jni problem
HI,fadden
I am very sorry.I don't know very well about jni,and I still don't
know the way to pass the data buffer
(point of void *)from native code to the android application.Could you
give me further explanation or give a example to do this.I have read
some document about jni,but it seems android's jni is difference with
stand java jni.so,I don't know how to to archive this without the
document.Thanks in advance.

[android-developers] Re: [android-developers]how to incude include static files(.a) in android jni application?
Thanks David.
I have this done by add my static library files to the the android's library
path.Thanks for help.
BTW. I have no NDK to use,and the static library is from other company.
2009/7/31 David Turner di...@android.com
You need to generate a shared library, not a static one, to be able to use
native code with JNI.
May I recommend you to download and use the Android NDK to do that?
