Custom Drawing | Android Developers - 1 views

  • Creating objects ahead of time is an important optimization. Views are redrawn very frequently, and many drawing objects require expensive initialization. Creating drawing objects within your onDraw() method significantly reduces performance and can make your UI appear sluggish.

      將物件在初始化時就實例化是很重要的概念,onDraw()的運作速度很快,如困每一個Paint畫圖物件都臨時才在onDraw()產生,將會大幅下降整体程式的流暢效能。
  • If your view doesn't need special control over its size, you only need to override one method: onSizeChanged().
  • is mandatory.

Android Essentials: Creating Android-Compliant Libraries - Tuts+ Code Tutorial - 1 views

  •  
    For a library to be compatible with Android, it can only reference classes available as part of Android and other classes implemented specifically in the library itself.Android Libraries can contain Java classes, resources, and other project information, but not assets. They can reference other libraries and leverage third party JAR files. They have Android manifest files just like regular Android projects. However, they differ from normal Android projects in an important way: they cannot be compiled into their own application packages or deployed onto devices. They can also not be exported as standalone JAR files. Once referenced from an Android project, the library components are incorporated into the Android application that references them at build time and added to the application package. There is no need to declare the component as the library classes are rolled into the APK directly. In terms of compatibility, the Android project must have an API Level higher than or equal to the API Level set in the Android library.
