android - Google Glass Broadcastreceiver across activities -

-

I have an activity where I am creating a Broadcast Reciver and with Bluetooth anyone I'm making connections on other devices. In my main activity there is a set of cards in CardScrollView . In this array, the cards are the devices that find my app that are able to establish the connection. When I connect to a device, I am opening another activity with another CardScrollView and the second set of cards, the Bluetooth connection remains, but I no longer exchange information Even if I return to main activity

The question is, should I register BroadcastReiveriver separately? Or is not my best thing about another activity?

Make your broadcast receiver independent of your activities, such as an event bus in a service or simply manifests With a mechanism as a separate class.

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

javascript - How to ignore requestAnimationFrame in browsers which don't support it -

-
Assume that we have a feature / module, which increases a website so it is not really necessary and it I use the requestAnimationFrame , which is like IE8 / 9, I could have polyphil requestAnimationFrame , but because it is only an increase, the old browser should ignore it. The code of this module looks more or less like this: ; {Function (window, document, undefined) {'strict use'; // example module // constructor function module, option) {// ...} Module.prototype = {init: function () {// if requestAnimationFrame Not supported, a warning warning ("init") should be popped up;}, method: function () {/ if the request animationfreck is not supported, then alert any warning ("Start");}}; Window.Module = Module;} (window, document) should pop up; Then I can create a new example var example = new module (document.getElementById ('test')); and "interact with" instance.init (); Instance.method (); The problem with this code ...
