cocos2dx_box2d实例1

## Prerequisites: * Android NDK * Android SDK **OR** Eclipse ADT Bundle * Android AVD target installed ## Building project There are two ways of building Android projects. 1. Eclipse 2. Command Line ### Import Project in Eclipse #### Features: 1. Complete workflow from Eclipse, including: * Build C++. * Clean C++. * Build and Run whole project. * Logcat view. * Debug Java code. * Javascript editor. * Project management. 2. True C++ editing, including: * Code completion. * Jump to definition. * Refactoring tools etc. * Quick open C++ files. #### Setup Eclipse Environment (only once) **NOTE:** This step needs to be done only once to setup the Eclipse environment for cocos2d-x projects. Skip this section if you've done this before. 1. Download Eclipse ADT bundle from [Google ADT homepage](http://developer.android.com/sdk/index.html) **OR** Install Eclipse with Java. Add ADT and CDT plugins. 2. Only for Windows 1. Install [Cygwin](http://www.cygwin.com/) with make (select make package from the list during the install). 2. Add `Cygwin\bin` directory to system PATH variable. 3. Add this line `none /cygdrive cygdrive binary,noacl,posix=0,user 0 0` to `Cygwin\etc\fstab` file. 3. Set up Variables: 1. Path Variable `COCOS2DX`: * Eclipse->Preferences->General->Workspace->**Linked Resources** * Click **New** button to add a Path Variable `COCOS2DX` pointing to the root cocos2d-x directory.  2. C/C++ Environment Variable `NDK_ROOT`: * Eclipse->Preferences->C/C++->Build->**Environment**. * Click **Add** button and add a new variable `NDK_ROOT` pointing to the root NDK directory.  * Only for Windows: Add new variables **CYGWIN** with value `nodosfilewarning` and **SHELLOPTS** with value `igncr` 4. Import libcocos2dx library project: 1. File->New->Project->Android Project From Existing Code. 2. Click **Browse** button and open `cocos2d-x/cocos2dx/platform/android/java` directory. 3. Click **Finish** to add project. #### Adding and running from Eclipse   1. File->New->Project->Android Project From Existing Code 2. **Browse** to your project directory. eg: `cocos2d-x/cocos2dx/samples/Cpp/TestCpp/proj.android/` 3. Add the project 4. Click **Run** or **Debug** to compile C++ followed by Java and to run on connected device or emulator. ### Running project from Command Line $ cd cocos2d-x/samples/Cpp/TestCpp/proj.android/ $ export NDK_ROOT=/path/to/ndk $ ./build_native.sh $ ant debug install If the last command results in sdk.dir missing error then do: $ android list target $ android update project -p . -t (id from step 6) $ android update project -p cocos2d-x/cocos2dx/platform/android/java/ -t (id from step 6)
