　又到了选择的时候，元宵节，公交遇贼，钱包里的身份证银行卡，统统被偷；被偷了，瞬间感觉“轻松了”，任何情况下我都可能回到原点，不是吗？不要担心选择必然所要做的放弃。

public class ShareSupport {    // when you want to use share(),firstly you should init acty.    public static Activity acty;        public static void share() {        new Thread(new Runnable(){            @Override            public void run() {                Intent intent = new Intent("android.intent.action.SEND");                  intent.setType("image/*");                      intent.putExtra(Intent.EXTRA_SUBJECT, "分享");                      intent.putExtra(Intent.EXTRA_TEXT, "终于可以了!!!");                intent.putExtra(Intent.EXTRA_STREAM,Uri.parse("file:////data/data/" + acty.getApplicationInfo().packageName+ "/share.png"));                Log.i("debug", "/data/data/" + acty.getApplicationInfo().packageName+ "/share.png");                intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);                     acty.startActivity(Intent.createChooser(intent, "分享"));             }                    }).start();    }}

拿出以前写android时的分享代码。

#include "jni_interfaces.h"#include <android/jni/JniHelper.h>extern "C" {    void Share()    {        cocos2d::JniMethodInfo jni_method_info;        cocos2d::JniHelper::getStaticMethodInfo(jni_method_info,"com/hortor/support/ShareSupport","share","()V");        if (jni_method_info.methodID)        {            jni_method_info.env->CallStaticVoidMethod(jni_method_info.classID, jni_method_info.methodID);        }    }}

c++代码越写越简洁了，删掉很多冗杂的地方。

#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)  Share();  CCLog("share ok");#endif

在分享按钮初调用jni_interfaces中的Share()函数。

ok不过有时，程序分享完会出现崩溃。

看到群里有问，如何从序列帧中获取一张图片，我贴出游戏中截图代码：

    CCSize size = CCDirector::sharedDirector()->getWinSize();    CCRenderTexture* in_texture = CCRenderTexture::renderTextureWithWidthAndHeight((int)size.width, (int)size.height,kCCTexture2DPixelFormat_RGBA8888);    in_texture->getSprite()->setAnchorPoint( ccp(0.5f,0.5f) );    in_texture->setPosition( ccp(size.width/2, size.height/2) );    in_texture->setAnchorPoint( ccp(0.5f,0.5f) );    in_texture->begin();    this->visit();    in_texture->end();    CCLog("%d",in_texture->saveBuffer(kCCImageFormatPNG,"share.png",0,0,800,480));
