beginner level sample codes

in Android
As a scientist trying to utilize kinematics sensor in a new way into research, I am a bit struggling with customizing existing sample codes into my purpose. (I have 3-4 yrs of programming experience in general but < 1year with android :(

Metawear-SampleAndroidApp is rather extensive sample but if not an expert in android I found it still challenging to customize the code. 
Another sample code is Metawear-AndroidStarter, which is rather too simple compared with the other one.

So I was wondering if there is any intermediate level samples between the two sample projects provided in the github. 
My immediate goal is to stream data from multi-sensors (2 Cpro's) to android and visualize gyro/acceleration data from the 2 boards in real time in a single panel. Trying to use line-chart but it's quite challenging.  

Could anyone provide any helpful samples related to visually monitoring multi-board data? 

Any help | advice will be greatly appreciated!

    What progress have you made in your app thus far?  

    For multiple MetaWears, check out this demo project from our projects GitHub repos.

    Hi Eric, thanks, I've taken classes provided in multimw for multi-connection and those are of good help.
    What I am struggling with is using hierarchy of gyroFragment/..SensorFragment/ModuleFragmentBase and inflate multiple copies of layout("fragment_sensor_config_spinner.xml") in multiple-fragment single panel to view multiple streaming chart in real time.  It is mainly my lack of experience but trying this for 2 weeks without success!  Keep getting null pointer error in getactvity() at onCreate of ModuleFragmentBase class.

    You can't inflate multiple layouts in a fragment, you will have to modify the original layout to accommodate the new UI.

    What you should focus on first is getting a reliable data stream from your board.  Once you have that working, then worry about adding the graph and UI elements.  I would actually work from the multimw code and update the UI with what you need.
