* Get a reference to the native ASurfaceTexture from the corresponding java object.
*
* The caller must keep a reference to the Java SurfaceTexture during the lifetime of the returned
* ASurfaceTexture. Failing to do so could result in the ASurfaceTexture to stop functioning
* properly once the Java object gets finalized.
* However, this will not result in program termination.
*
* Available since API level 28.

* \param env JNI environment
* \param surfacetexture Instance of Java SurfaceTexture object
* \return native ASurfaceTexture reference or nullptr if the java object is not a SurfaceTexture.
* The returned reference MUST BE released when it's no longer needed using
* ASurfaceTexture_release().
