    "We are building a community-written web site which has also been used to create an O'Reilly Cookbook, both about how to build great Android applications. It is full of how-to information along with code snippets that illustrate the ideas presented. It features both how-to's that overlap with the official documentation, and material that goes beyond this to be more tutorial, more in-depth, or explaining "lessons from the trenches": what actually works to get the application functioning well. Unlike most books written by one, two or a few individuals, this one has input from dozens of contributors, who were all able to view and comment on each others' recipes before the book was published. The published version(s) include printed books, eBooks, and other uses"

android search tech

  • 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

How QR Codes Can Grow Your Business | Social Media Examiner - 1 views

QR codes Business trends

shared by Vincent Tsao on 18 May 11 - No Cached
  • Consumers want immediate access to what’s relevant and QR codes are being used to make that possible.
  • Bar codes are linear one-dimensional codes and can only hold up to 20 numerical digits, whereas QR codes are two-dimensional (2D) matrix barcodes that can hold thousands of alphanumeric characters of information. Their ability to hold more information and their ease of use makes them practical for small businesses.
  • When you scan or read a QR code with your iPhone, Android or other camera-enabled Smartphone, you can link to digital content on the web; activate a number of phone functions including email, IM and SMS; and connect the mobile device to a web browser.
  • ...4 more annotations...
  • There are other software companies that have created 2D codes that work much like QR codes, with Microsoft being the most notable.  Microsoft developed their own proprietary software to create codes known as MS tags.  Unlike QR codes, which can be read by a number of different readers, MS tags can only be read by the Microsoft Tag Reader.
  • Calls to Action – After building a community, the next logical step is to mobilize them to take action.   What are you trying to accomplish?  You can alternate special offers by simply linking your QR codes to new landing pages, and you can combine then with email opt-ins to build your list.
  • SEO and SMO – Earlier this month I wrote an article on social graphs where I discuss how web objects such as images, music clips, and videos add valuable content to your social graph.  QR codes enhance both your search engine and social media optimization.  Now you can increase traffic to those searchable objects to further optimize them by encouraging more sharing.
  • Social Proof – To help build a community offline, it can be helpful to use your vibrant online communities as social proof of your influence and expertise.  As one example, you can use QR codes to link to specific blog posts that have earned an abundance of activity.
