Native app & cocos2d-x integration scafold
=========

Android and Cocos2D-x integration scafold for testing purpouses.

> What it does:
> 
> This is a test Cocos2D-x app that runs inside another Android App.
> When you click the button, the Android native app writes a file on /data/data/package/files/ folder with some data on it. The Coco2D-x app that get launched will read this file and show it on a CCLabelText. This scafold also includes Backbutton implementation for killing the Cocos2D-x part of the application.

Begin integration:
--------

Start by creating a Cocos2D-X project.

```
    // Create project
    asier:~ $ cocos new MyCocosGame -p com.irontec.axierjhtz -l cpp -d ~/Desktop/CocosGame
```

Import libcocos2dx

```
    MyCocosGame/cocos2d/cocos/2d/platform/java/
```

If using Eclipse, importing MyCocosGame could help making things more easy.

Copy org.cocos2dx.cpp package to your Android project

Modify AppActivity.java

```
	package org.cocos2dx.cpp;

import org.cocos2dx.lib.Cocos2dxActivity;
	import org.cocos2dx.lib.Cocos2dxGLSurfaceView;

public class AppActivity extends Cocos2dxActivity {

public Cocos2dxGLSurfaceView onCreateView() {
			Cocos2dxGLSurfaceView glSurfaceView = new Cocos2dxGLSurfaceView(this);
			glSurfaceView.setEGLConfigChooser(5,6,5,0,16,8);
			return glSurfaceView;
		}
	}
```

Modify you MainActivity.java to write params on a file.

```
    // This function will write a .txt file 
    // in /data/data/package/files/ folder
    public void writeToInternalFilesDir(String filename) {
		JSONObject obj = new JSONObject();
		try {
			obj.put("1", "Hello World");
		} catch (JSONException e1) {
			e1.printStackTrace();
		}
		
		BufferedWriter writer;
		try {
			File path = new File(getActivity().getFilesDir(), filename);
			writer = new BufferedWriter(new FileWriter(path));
			writer.write(obj.toString());
			writer.close();
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
```

Navigate to YouFolder/CocosGame/MyCocosGame/Classes/ and modify HelloWorldScene.cpp to add the parameter interceptor.

```
    // This snippet reads a file located 
    // in /data/data/package/files/ folder
    std::string path = CCFileUtils::getInstance()->getWritablePath() + "gane_data.txt";
    FILE *fp = fopen(path.c_str(), "r");
    std::char buf[200] = {0};

if (! fp)
    {
        CCLOG("can not open file %s", path.c_str());
    } else {
        fgets(buf, 200, fp);
        CCLOG("read content %s", buf);
    }
```

Now compile everything and run the app standalone to see if the code it´s Ok.

```
    asier:~ $ cocos run -s ~/Desktop/CocosGame/MyCocosGame/ -p android
```

After compiling the project check if everithing is ok and then refresh every project on Eclipse just to make sure all changes have been applied.

Copy jni, obj folders to your project root

Copy assets folder content to your project assets folder.

From bin directory copy dexedLibs, classes.dex, classes.dex.d, all .apk, apk.d, ap and ap_.d files.

From libs folder copy all the armeabi folder to your project libs folder.

Modify your projects AndroidManifest.xml file so you can add the AppActivity activity. Remenber to remove the intent filters for this activity. Add the glEsVersion.

Run and test (AVD with armeabi config).

Backbutton implementation
----

For implementing Backbutton functionality you need to modifiy Cocos2dxGLSurfaceView.java

```
    //...
        private Cocos2dxActivity mActivity;
    //...

//...
    
        // ===========================================================
        // Constructors
        // ===========================================================
        public Cocos2dxGLSurfaceView(final Activity activity) {
                super(activity.getBaseContext());
                this.mActivity = (Cocos2dxActivity) activity;
                this.initView();
        }
    // ...

// ...
        @Override
        public boolean onKeyDown(final int pKeyCode, final KeyEvent pKeyEvent) {
                switch (pKeyCode) {
                case KeyEvent.KEYCODE_BACK:
                        if (mActivity != null && !mActivity.isFinishing()) {
                                mActivity.finish();
                        }
                case KeyEvent.KEYCODE_MENU:
                        this.queueEvent(new Runnable() {
                                @Override
                                public void run() {
                                        Cocos2dxGLSurfaceView.this.mCocos2dxRenderer.handleKeyDown(pKeyCode);
                                }
                        });
                        return true;
                default:
                        return super.onKeyDown(pKeyCode, pKeyEvent);
                }
        }

// ...
```

This should do the work.
