API level >= 21

From API 21 onwards, the C++ Allocation::getPointer function is available, and can be used invoking the rsAllocationGetPointer function (please look at the Native kernel calling section to understand how to do it), declared as follows (rsAllocation.cpp):

void *rsi_AllocationGetPointer(Context *rsc, RsAllocation valloc, uint32_t lod, RsAllocationCubemapFace face, uint32_t z, uint32_t array, size_t *stride, size_t strideLen) { Allocation *alloc = static_cast<Allocation *>(valloc); rsAssert(strideLen == sizeof(size_t)); return alloc->getPointer(rsc, lod, face, z, array, stride); }
