Platforms that do not provide a memory backend implementation should keep using the maxJpegBufferSize() value to calculate the location where to place the JPEG blob id, as the android_generic backend returns the allocated buffer size as calculated using lseek which is larger than the maximum JPEG frame size, which is where the framework expects the JPEG blob to be placed.
