Android RenderScript Allocation copy from NIO Direct ByteBuffer -

on android platform (api-19) copy direct byte buffer render script allocation. possible improve following code, example using ndk?

final bytebuffer buffer = ...src;  final byte[] bytes; if (buffer.hasarray()) {     bytes = buffer.array(); } else {     bytes = new byte[buffer.capacity()];     buffer.get(bytes);     buffer.rewind(); } allocation.copyfromunchecked(bytes); 

unfortunately, no. apis not constructed can provide backing data store allocation or retrieve nio based buffer allocation created. closest thing use have bitmap based allocation created usage_shared sync'd differences rather full copy.
