其實,我個人學習Android最主要的目的是學習在此平台下的3D效果的開發。所以,我們開始進入主題吧。 OpenGL ES (OpenGL for Embedded Systems) 是 OpenGL 三維圖形 API 的子集,針對手機、PDA和遊戲主機等嵌入式裝置而設計。該API由Khronos集團定義推廣,Khronos是一個圖形軟硬體行業協會,該協會主要關注圖形和多媒體方面的開放標準。 在Android中搭建一個3D開發的基本架構:一、匯入opengl
記錄了Android系統上由於cursor泄露導致記憶體耗盡(error -12)導致的CursorWindow不能再建立的Issue。[Symptom]08-30 20:27:36.751 E/CursorWindow( 760): Could not allocate CursorWindow '/data/data/com.android.providers.media/databases/external.db' of size 2097152 due to

以下是本人日常工作中收集的比較不錯的Android開源項目,歡迎博友提供未收錄的網址。 roottools: RootTools gives Rooted developers easy access to common rooted tools... mmsbg: mms bg for auto send msg and auto dial acra:
Most apps have an inherent information model that can be expressed as a tree or graph of object types. In more obvious terms, you can draw a diagram of different kinds of information that represents the types of things users interact with in your
Decide on a Substitute SolutionThe most challenging task in using newer UI features in a backward-compatible way is deciding on and implementing an older (fallback) solution for older platform versions. In many cases, it's possible to fulfill
CursorLoader returns its query results to your implementation ofLoaderCallbacks.onLoadFinished(), in the form of a Cursor. In the callback, you can update your data display, do further processing on theCursor data, and so forth. http://blog.csdn.net/
