    这句话是写在第4点 Use the Custom Component中∶ Notice that the MyEditText class is now a separate class file. 1.When the class is nested in the NoteEditor class, this technique will not work. 我还没真实遇到，Diigo先！ 总之告诉我们如果将自己写的View写成内部类时， XML会找不到！

  • Getting Started Welcome to Training for Android developers. Here you'll find sets of lessons within classes that describe how to accomplish a specific task with code samples you can re-use in your app. Classes are organized into several groups you can see at the top-level of the left navigation. This first group, Getting Started, teaches you the bare essentials for Android app development. If you're a new Android app developer, you should complete each of these classes in order:

    This site hosts a library for Near Field Communication on Android using the NDEF format.. In particular the site provides an eclipse plugin for the developers to create NDef records for various use cases - URI, Smartposter, Event etc. There is also an associated application hosted on Google Play store which is very useful in composing complex NDEF records and burning on Tags

Handling User Interaction with Android App Widgets - Developer.com - 0 views

android Widget button tech

shared by Vincent Tsao on 08 Jul 10 - Cached
  • An App Widget uses a special display control called RemoteViews. Unlike a regular View, a RemoteViews control is designed to display a collection of View controls in another process. Consequently, you can't simply add a button handler because that code would run in your application process, not in the process displaying the RemoteViews object (in this case, the Home Screen process).
  • In order to handle user interaction with an App Widget, the following tasks must be performed: Set a unique click handler for each App Widget control Have the click handler send a command to a registered receiver Process the command received and perform any action necessary Update the App Widget to reflect the changes

Is it possible to update a widget from an Activity? - Android Developers | Google Groups - 0 views

android AppWidget Widget tech

shared by Vincent Tsao on 13 Jul 10 - Cached
  • An AppWidgetProvider is a BroadcastReceiver. That gives you two possibilities right off the bat: 1. Have it also handle whatever other Intents you were planning on setting up with a separate BroadcastReceiver, or 2. Send an Intent from whatever component you want to the AppWidgetProvider. In other words, don't worry about trying to talk directly to the app widget (which I suspect is impossible) -- just talk to your code that already talks to the app widget.

      good explanation
  • I update my widget from within my app, when I delete/add entries to a list. To do this, I have a method (updateWidget) and a static String (UPDATE_ACTION). My updateWidget() method sends a broadcast which is received by the widget class and then calls onUpdate() with the appropriate params: private void updateWidget() {                 Intent i = new Intent(this, TVWidget.class);                 i.setAction(TVWidget.UPDATE_ACTION);                 sendBroadcast(i);         } In TVWidget class: @Override         public void onReceive(Context context, Intent intent) {                 String action = intent.getAction();                 if (action != null && action.equals(UPDATE_ACTION)) {                         final AppWidgetManager manager = AppWidgetManager.getInstance (context);                         onUpdate(context, manager,                                         manager.getAppWidgetIds(new ComponentName(                                                         context, TVWidget.class)                                         )                         );                 }                 else {                         super.onReceive(context, intent);                 }         } This seems to work fine.

Try loadDataWithBaseUrl() instead of loadData(), supplying some bogus value for the base URL (e.g., fake://why/o/why/is/this/needed).

Android Cloud to Device Messaging Framework - Google Projects for Android - 1 views

code.google.com/c2dm

android C2DM google

shared by Vincent Tsao on 24 May 10 - Cached
  • It allows third-party application servers to send lightweight messages to their Android applications. The messaging service is not designed for sending a lot of user content via the messages. Rather, it should be used to tell the application that there is new data on the server, so that the application can fetch it. C2DM makes no guarantees about delivery or the order of messages. So, for example, while you might use this feature to tell an instant messaging application that the user has new messages, you probably would not use it to pass the actual messages. An application on an Android device doesn’t need to be running to receive messages. The system will wake up the application via Intent broadcast when the the message arrives, as long as the application is set up with the proper broadcast receiver and permissions.
  • It uses an existing connection for Google services. This requires users to set up their Google account on their mobile devices.
  • C2DM imposes the following limitations: The message size limit is 1024 bytes. Google limits the number of messages a sender sends in aggregate, and the number of messages a sender sends to a specific device
  • ...1 more annotation...
  • The ClientLogin token authorizes the application server to send messages to a particular Android application. An application server has one ClientLogin token for a particular 3rd party app, and multiple registration IDs. Each registration ID represents a particular device that has registered to use the messaging service for a particular 3rd party app.

  • Droid-Fu offers both support classes meant to be used alongside existing Android code, as well as self-contained, ready-to-be-used components like new adapters and widgets. The areas tackled by Droid-Fu include: application life-cycle helpers support classes for handling Intents and diagnostics better support for background tasks super-easy and robust HTTP messaging powerful caching of Objects, HTTP responses, and remote images custom adapters and views I suggest you read this introductory article, and anything that follows.

    大哥你有覺得這個比AsyncTask好用嗎？

    BetterAsyncTask本质就是AsyncTask，我想在用法上应该没有太大区别 但AsyncTask有个硬伤就是它的life-cycle对当前的activity的life-cycle有依赖，容易引起FC，而BetterAsyncTask解决了这个问题，Ref: http://groups.diigo.com/group/android_related/content/introducing-droid-fu-for-android-betteractivity-betterservice-and-betterasynctask-brain-flush-2838716 当然还有其他解决办法，我自己偏向于 IntentService + Broadcast mechanism的解决方案

    在我最近的案子裡 幾乎很少機會用到IntentService。 我目前唯一用到的是AsyncTask， 而且那還是我硬用，才有機會用到它。

android svg

shared by Vincent Tsao on 17 May 11 - No Cached
  • This is a compact and straightforward library for parsing SVG files and rendering them in an Android Canvas. By using vector art, the pain of supporting various screen sizes and densities in Android can be reduced. This was the library used to render the artwork and the interface of Androidify. The project also includes a Live Wallpaper app extracted from Androidify. The app shows off the SVG library, and demonstrates the rendering pipeline used to draw the Androids.
