android - Pass data efficiently across JNI as well as renderscript -

I intend to read YUV frames from the JNI level, implement them in the renderScript and then present them. I'm very curious if there is an effective way to pass the block of data without too many copy ops. Right now, I'm returning Java as ByteBuffer as frame using NewDirectByteBuffer () . But it seems that I can not build directly on this allotment on this ByteBuffer .

So my question is, can I do this in only two copy operations or the data in allocation

to SurfaceView Copy (I think there is a copy operation in the rendering part, such as canvas.Ssetbitimype (BMP)

From the MongoDB site:  "Documents stored in a collection require a unique _id field which acts as the primary key.

    How to install a package in Cyrus image?   I do not have any installer available in the Siros image that comes with devstack installation.
