问题 I'm currently working on an app that connects to a bluetooth device and receives a message every .25 seconds, then displays that data on screen. The user will also be able to arbitrarily start/stop logging this data to a file on the SD card. I have tried extending a thread class that listens for the messages from the BT device, and then using a handler to send the data back to the UI thread and display it. This was working fine, but on configuration changes, like screen rotation, when the

问题 I know about the Windows Phone 8.1 Applications lifecycle: http://msdn.microsoft.com/en-us/library/windowsphone/develop/ff817008%28v=vs.105%29.aspx But, is it possible to keep active the application when it is not used (after deactivation)? Is it possible to realize a WP8.1 App that sends some data to a Server at predetermined time intervals? Is it possible to execute code in the App, when it is deactivated? 回答1: As you have tagged your question for WP8.1, apart from Silverlight apps, there

问题 Short Version I've found that WLClient lifecycle is bound to Activity. Activity lifecycle is managed by OS. Do you have any recommendations to compensate this? Long Version For Android Native project, the first step should be create a WLClient instance by the following call WLClient.getInstance(Context ctx) From the API document, it's a Context, not an Activity, but in reality, there would be a type cast in WLPush.java in WL framework. It doesn't make sense to bind a WLClient to a Activity,

问题 I have my angular app set up with an ng-view directive in the index.html, with views configured with $routeProvider config and each view having its own controller. In one view controller, I have a $rootScope.$on listener that watches for events. I expect this listener to no longer run when I change views, but this is not the case. The watch still keeps calling code when it is triggered, even when I have switched to a view that is no longer using that controller. I have set up some test code

问题 in my app I have a single activity with a container layout for a fragment. In Activity's @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Logger.enable(); setContentView(R.layout.activity_main); FragLobby fragLobby = (FragLobby)getSupportFragmentManager().findFragmentByTag(FragLobby.debugTag); if(fragLobby==null) fragLobby = new FragLobby(); FragmentHelper.replaceSupportFragment(this, fragLobby, R.id.llMain, false, FragLobby.debugTag); /

问题 I'm using Sails.js v0.10.5, but this probably applies to more general MVC lifecycle logics (Ruby on Rails?). I have two models, say Foo and Baz , linked with a one-to-one association. Each time that data in a Foo instance changes, some heavy operations must be carried out on a Baz model instance, like the costlyRoutine method shown below. // api/model/Foo.js module.exports { attributes: { name: 'string', data: 'json', baz: { model: 'Baz' } }, updateBaz: function(criteria,cb) { Foo.findOne(

问题 I'm developing a mobile puzzle game in Unity, when I exit my game to the home screen and return back- the game continues from the same spot and it seems to be fine (without overriding onPause/onStart), am I missing something? Do I need to store variables when exit? What do people usually save? I'm afraid to have bugs in the future. 回答1: I missing something? Yes Do I need to store variables when exit? Yes I'm afraid to have bugs in the future. Yes, you will. You will run into lost variables

问题 After reading some questions/answers about activity and process lifecycle. I suppose I understand the details about activity and process lifecycle. But I'm confused about these Observers like BroadcastReceiver/ContentObserver with process lifecycle . What I want to know is, when I register a BroadcastReciver (i.e, a BroadcastReceiver listen on SMS receive intent),if the process which registered the BroadcastReceiver does exist already, when the system calls the BroadcastReceiver, is it in the

问题 I am using call_number plugin to make a call from my app. I am tracking the AppLifecycleState to take actions. This is the order in which states are changing- AppLifecycleState.inactive AppLifecycleState.resumed AppLifecycleState.inactive AppLifecycleState.paused AppLifecycleState.inactive AppLifecycleState.resumed Last 4-I understand the flow, but I am unable to understand why is state changing to resumed the first time. According to the documentation - "The application is visible and
