  Information on bag files can be found here:

  https://github.com/IntelRealSense/librealsense/blob/master/doc/sample-data.md 

  The RealSense Viewer program can record data from its "2D" mode into a bag file.  More information on the recording and playback of bag files in the RealSense SDK can be found here:

  https://github.com/IntelRealSense/librealsense/tree/master/examples/record-playback 

  Because a bag file contains unfiltered data, changes such as alignment between depth and color or post-processing filtering cannot be saved within a bag file.  Instead, a bag file can be loaded back in as a playable sequence containing all the streams that were active during the recording process.  Post-processing and other real-time adjustments can then be applied to that loaded-in data.

   

  3D point cloud data from the Viewer's "3D" mode is not stored in a bag file but is instead recorded into a ply file.

  The answer is a bit complicated.  It has been demonstrated to be possible to do SLAM on an Android device using the Robot Operating System (ROS) software.  And the RealSense SDK is fully compatible with ROS using a ROS compatibility 'wrapper' module.

  So whilst SLAM on Android using the Librealsense SDK on its own may not be practical, it may be achievable to use a RealSense 400 Series camera with ROS to perform SLAM mapping on Android.
