Android API Tutorial Series

Hi all,

I've put together a basic tutorial series for the MetaWear Android API. A while back I got a message from one of the users on this forum asking more about some code I wrote combining accelerometer and gyroscope data, and it got me thinking that I should document what I've been learning. For developers like me, who don't have a background in Android (or iOS), I think it can be a bit of a jump from the documentation to the sample app. I've tried to bridge that gap in this series. Hope it helps, and apologies in advance for any errors!


Cheers,

Chris

    Wow!  This is a very detailed guide, going beyond just a HowTo for MetaWear.  The guide looks pretty solid to me; I only have two nitpicks.

    First, you can stream and log the same signal.  As you mentioned, its not a recommended use case but neither the api nor firmware stop you from doing so if you need or want to.

    Second, I noticed your code examples only wrapped the getModule calls in try-catch blocks and not the rest of the code.  The getModule function is marked with a checked exception because no board contains all modules.  Your code should handle this case and writing code in this manner completely disregards the purpose of exceptions.

    However, I can understand that if you are developing on one type of board, then you would already know what modules are present thus doing exception handling for a function that will never throw one is meaningless.  Down the line, I would like to add a getModule variant that doesn't throw an exception for those users.

    All in all, nice job and thanks for writing this up for the community.
