Are you running CM11 with ART or with Dalvik??
I downloaded NookChargerControl.apk and when I try to install it on my HD+ with CM11 and ART it gives a parse error (says 'there was a problem parsing the package.')
0x32 is 500mAh, so it tries to draw this much, but if charge current in the battery is 0, that means there's not enough power left after what's used by tablet itself with screen on.
I have this problem with my iPhone chargers, not sure how the charger controller differentiates.
Big win for me is with a computer port, where with the app and a new kernel I can draw much more current and keep battery charging even with the screen on
It is part of standard kernel now, so if you use CM nightlies or any of my recent binary drops, it's already in and you just need to install the app.
Sadly there's no real choice available here from the controllerTo speak frankly, I didn't test it until now, but would it be good to provide the app with a few buttons with different charge rates (500mA, 1 A, 1.25 .. 1.5) so that user has the choice to select that best matching rate for the charger? (I hope I didn't misunderstand the feature of setting the rate by register values).
I guess it could be trivially added, though in reality there's this battery-reported current that is the important part and is accurate.Is there any chance you could update the app to include the above information on the screen? I can never remember what the register values equate to amperages.
Also, could you identify some kind of unit for the battery-reported current? Is that miliamperes/hour or what?
