/**

 * Return the AHardwareBuffer associated with a Java HardwareBuffer object,

 * for interacting with it through native code.  This acquires a reference

 * on the AHardwareBuffer that is returned; be sure to use

 * AHardwareBuffer_release() when done with it so that it doesn't leak.

 * for interacting with it through native code. This method does not acquire any

 * additional reference to the AHardwareBuffer that is returned. To keep the

 * AHardwareBuffer live after the Java HardwareBuffer object got garbage

 * collected, be sure to use AHardwareBuffer_acquire() to acquire an additional

 * reference.
