HelloIOIO vs HelloIOIOPower

[Rajan Gupta]

Hi All,

HelloIOIOPower code mentions following statement:

---------------------------------------------------------------------------------------

* Compared to the HelloIOIO example, this example does not use the

 * AbstractIOIOActivity utility class, thus has finer control of thread creation

 * and IOIO-connection process. For a simpler use cases, see the HelloIOIO

 * example.

---------------------------------------------------------------------------------------

In what way is HellIOIOPower superior in IOIO Connection Process. I feel, the same thing is being done for HelloIOIO code also, in one of the API libraries for the connection process.

Regards,

Rajan

When I first wrote HelloIOIOPower, it was impossible for an app extending AbstractIOIOActivity to respond to a disconnect. This has now changed, so HelloIOIOPower doesn't do anything that cannot be done with AbstractIOIOActivity.

However, the point being made remains valid:

You don't have to use AbstractIOIOActivity (and stick to the setup-loop-loop-loop-disconnect paradigm, to starting and stopping the connection in response to activity pause / resume, or to a single IOIO thread) for writing IOIO applications. You can explicitly create the IOIO object, and call waitForConnect() / disconnect() whenever you want, and do whatever you want with the IOIO instance, even from multiple threads at the same time (the API is completely thread-safe).

Hi, Ytai. For some reason, I couldn't use the IOIOService and IOIOActivity. So I explicitly create the IOIO object with the code "ioio = IOIOFactory.create()", but I got this error:

I'm sure I got all the permissions the app needs. It is very likely I use it in a wrong way. Please help me and Thank you.

Warm regards,

Jeffrey.

You'd need to do something like this:

https://github.com/ytai/ioio/blob/master/software/IOIOLibAndroid/src/main/java/ioio/lib/util/AbstractIOIOActivity.java#L87

But be warned, that you're choosing a very dis-recommended approach.
