DataLogger APK needs security update

[GoogleCodeExporter]

The demo com.cellbots.logger DataLogger

needs to be reviewed and updated, the camera api crashes and the write/zip is 
prevented by the 2.3 and 4 android security updates.

This is a good example and possibly the only functional sensor logger.

The initial setup needs to poll all available cameras (more than 2 possible) 
and option select their maximal resolution or framerate.

Logging needs an option to segment into directories or time stamped files with 
variable duration (10 second sensor data each directory or filename, images 
timestamped)

It is possible to record and snap both front and rear simultaneously on many 
devices, and fast throttle between front and rear cameras is possible (sans 
system delay) and alternation should be included in the settings.

Cameras must be set for INFINITE focus or the demo will be useless for use.

It is possible to use HEVC 265 to encode 8k sequential images from the cameras 
allowing maximal resolution regardless of frame rate. 

There are methods to force maximal frame rate recording, both in video stream 
and photo burst.

There are options to more accurately set the SAMPLE RATE which currently is too 
slow.

There is significantly more information available, a snapshot of all system 
status can be collected at certain interval or upon each fragment.

The host system's status should also be logged, cpu, temp, memory so that 
failures can be tracked.

A number of sensors are not included, namely the signals (phone, wifi, etc) and 
Audio/input when not using system mp4 video

options for the demo.
