onReceive(): The default implementation of this method handles the BroadcastReceiver actions and makes the appropriate calls to the methods shown above. (Warning: A well-documented defect exists that requires the developer to handle certain cases explicitly. See the following note for more information.)

AndroidAnnotations - 0 views

Using Java annotations, developers can show their intent and let AndroidAnnotations generate the plumbing code at compile time. Few Features are * Dependency injection: inject views, extras, system services, resources, ... * Simplified threading model: annotate your methods so that they execute on the UI thread or on a background thread. * Event binding: annotate methods to handle events on views, no more ugly anonymous listener classes! * REST client: create a client interface, AndroidAnnotations generates the implementation. * AndroidAnnotations provide those good things and even more for less than 50kb, without any runtime perf impact!

Additionally, you can feel free to use the Search bar selection mechanism as a replacement for tabs since it’s really just a fast pivot on a data set. If you have more than 3 data sets, tabs become problematic since no more than 3 can be onscreen at once. For example, look at how we implemented the Profile switching mechanism below:

Search | Android Developers - 0 views
-
Android's search framework provides a user interface in which users can perform a search and an interaction layer that communicates with your application, so you don't have to build your own search Activity. Instead, a search dialog appears at the top of the screen at the user's command without interrupting the current Activity.

我是在实现了一个自己的search activity后看到这篇文章了，oh~shit

Using the Android Search Dialog | Android Developers - 0 views
-
If your data is stored in a SQLite database on the device, performing a full-text search (using FTS3, rather than a LIKE query) can provide a more robust search across text data and can produce results significantly faster.
-
If your data is stored online, then the perceived search performance might be inhibited by the user's data connection. You might want to display a spinning progress wheel until your search returns.
-
<?xml version="1.0" encoding="utf-8"?><searchable xmlns:android="http://schemas.android.com/apk/res/android" android:label="@string/app_label" android:hint="@string/search_hint" ></searchable>
-
这个地方一定要记得在string.xml文件中定义label，并在此处refrence定义好的label key。直接在里面写value是不会work的，得出这个结论我花了2个小时！
-
android:label="@string/app_label" 如果我写成 android:label="test", 铁定不能invoke search，不知道为什么Android要区别对待，我认为这是Android的一个bug

But in practice, you will notice that the AsyncTask is limited to 10 threads. This number is hardcoded somewhere in the Android SDK so we cannot change this. In this case it’s a limitation we cannot live with, because often more than 10 images are loaded at the same time.

使用AsyncTask类开辟的线程还有数量限制？必须小于10，这个倒是以前没有注意到的，要看看源代码怎么实现的

I’ve shown you how to improve performance of a ListView in three different ways: By loading images in a seperate thread By reusing rows in the list By caching views within a row

This projects aims to provide a reusable action bar widget. The action bar replaces the default title and is therefor located at the top of the screen. The action bar highlights important actions. The action bar pattern is well documented over at Android Patterns. The action bar widget is an Library Project. This means that there's no need to copy-paste resources into your own project, simply add the action bar widget as a reference to your existing project.

Moreover I am not one of top developers nor any of my apps have been promoted by Android Market. I am just an one among of thousands of Android developers with not to well known apps. And what may be really surprising all my apps are free as Google do not allow developers from my country (Poland) to sell apps via Android Market!
-
So keep in mind these facts: None of my apps has been ever promoted in Top of Android Market I am providing only free apps (mostly due of Android Market limitations) Even if I would be able to sell apps I would not use it as main income source… (I believe that you still can make more from ads…)
