android adb sqlite

  • Then I went ahead and installed 2.2 and now when > I type sqlite3 in the shell it says sqlite3 not found....  Any ideas? Well, it's in the 2.2 emulator image, for what that's worth. -- Mark Murphy (a Commons Guy)

    Android 2.2 的真机中不再有sqlite调试工具了? WTF! ! !

    求助于China android dev开发小组，有了解决办法： step 1: 从其他真机或者模拟器的 /system/xbin目录下copy一份 sqlite3 step 2: 进入shell执行chmod a+x sqlite3 或者 chmod 777 sqlite3 大功告成

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

android IntentService

shared by Vincent Tsao on 20 May 11 - No Cached
  • AsyncTask要点 1、必须从主线程调用，或者线程中有Handler或Looper。 2、不要在一个可能会被另外一个AsyncTask调用的库里面使用AsyncTask（AsyncTask是不可重入的） 3、如果从一个activity中调用，activity进程可能会在AsyncTask结束前退出，例如： 用户退出了activity 系统内存不足 系统暂存了activity的状态留待后用 系统干掉了你的线程 如果AsyncTask中的工作很重要，应该使用……
  • IntentService 的好处 Acitivity的进程，当处理Intent的时候，会产生一个对应的Service Android的进程处理器现在会尽可能的不kill掉你 非常容易使用
  • 总结 离开主线程！ 磁盘和网络操作不是马上就能完的 了解sqlite在干嘛 进度展示很好
