        Android微信SDK实现分享 里面有写好的manager可以直接使用 ,感谢博主分享 ，但里面有个要注意的地方就是博主为了分享内容的复用导致如果你想分享不同内容的时候出现分享的还是上一个的分享，内容具体请看下面的我写的微信分享的代码红字注释

常见问题 ：

      1.QQ空间分享打不开不报错，但就是打不开页面

　　　　注意：有可能你写成了是这段代码

private void shareToQzone () {
　　//分享类型
　　params.putString(QzoneShare.SHARE_TO_QQ_KEY_TYPE,SHARE_TO_QZONE_TYPE_IMAGE_TEXT );
    params.putString(QzoneShare.SHARE_TO_QQ_TITLE, "标题");//必填
    params.putString(QzoneShare.SHARE_TO_QQ_SUMMARY, "摘要");//选填
    params.putString(QzoneShare.SHARE_TO_QQ_TARGET_URL, "跳转URL");//必填
    params.putString(QzoneShare.SHARE_TO_QQ_IMAGE_URL, "图片链接ArrayList");
    mTencent.shareToQzone(activity, params, new BaseUiListener());
}

你注意这里的params.putString(QzoneShare.SHARE_TO_QQ_IMAGE_URL, "图片链接ArrayList");

这里是错误的，因为要写成这样

ArrayList<String> imageUrls = new ArrayList<String>();

imageUrls.add("https://pic.cnblogs.com/avatar/677455/20150707171133.png");

params.putStringArrayList(QzoneShare.SHARE_TO_QQ_IMAGE_URL,imageUrls); 

后面是个集合不是一个String

应该是这样写代码

/**
     * 分享到QQ空间
     */
    public static void shareToQzone(Context context,IUiListener listener) {
        //分享类型
        final Bundle params = new Bundle();
        params.putInt(QzoneShare.SHARE_TO_QZONE_KEY_TYPE,QzoneShare.SHARE_TO_QZONE_TYPE_IMAGE_TEXT);
        params.putString(QzoneShare.SHARE_TO_QQ_TITLE, "标题                    ");//必填
        params.putString(QzoneShare.SHARE_TO_QQ_SUMMARY, "摘要              ");//选填
        params.putString(QzoneShare.SHARE_TO_QQ_TARGET_URL, "http://www.qq.com/news/1.html");//必填
        ArrayList<String> imageUrls = new ArrayList<String>();
        imageUrls.add("https://pic.cnblogs.com/avatar/677455/20150707171133.png");
        params.putStringArrayList(QzoneShare.SHARE_TO_QQ_IMAGE_URL,imageUrls);
        mTencent.shareToQzone((Activity)context, params, listener);
    }

传的参是 list  而且params.putStringArrayList()  而不是params.puString();

QQ分享本地和网络图片跟下面的红色标注有关  QQShare开头

/**
     * QQ分享内容
     * 分享的是本地图片 SHARE_TO_QQ_IMAGE_LOCAL_URL
     * 分享的是网络图片 SHARE_TO_QQ_IMAGE_URL
     * @param context
     * @param listener
     */
    public static void shareText(Context context, BeanShareInfo info,IUiListener listener) {
        final Bundle params = new Bundle();
        params.putInt(QQShare.SHARE_TO_QQ_KEY_TYPE,QQShare.SHARE_TO_QQ_TYPE_DEFAULT);
        params.putString(QQShare.SHARE_TO_QQ_TITLE, info.getTitle());
        params.putString(QQShare.SHARE_TO_QQ_SUMMARY, info.getDescription());
        params.putString(QQShare.SHARE_TO_QQ_TARGET_URL, info.getTargetUrl());
        params.putString(QQShare.SHARE_TO_QQ_IMAGE_URL, info.getShareCoverUrl());
        params.putString(QQShare.SHARE_TO_QQ_APP_NAME,  info.getAppName());
        params.getInt(QQShare.SHARE_TO_QQ_EXT_INT);
        mTencent.shareToQQ((Activity)context, params, listener);
    }

QQ空间分享也是 但注意的是QQ空间是 QzoneShare 开头

 /**
     * 分享到QQ空间
     * 分享的是本地图片 SHARE_TO_QQ_IMAGE_LOCAL_URL
     * 分享的是网络图片 SHARE_TO_QQ_IMAGE_URL
     */
    public static void shareToQzone(Context context, BeanShareInfo info, IUiListener listener) {
        //分享类型
        final Bundle params = new Bundle();
        params.putInt(QzoneShare.SHARE_TO_QZONE_KEY_TYPE,QzoneShare.SHARE_TO_QZONE_TYPE_IMAGE_TEXT);
        params.putString(QzoneShare.SHARE_TO_QQ_TITLE,info.getTitle());//必填
        params.putString(QzoneShare.SHARE_TO_QQ_SUMMARY, info.getDescription());//选填
        params.putString(QzoneShare.SHARE_TO_QQ_TARGET_URL, info.getTargetUrl());//必填
        ArrayList<String> imageUrls = new ArrayList<String>();
        imageUrls.add(info.getShareCoverUrl());
        params.putStringArrayList(QzoneShare.SHARE_TO_QQ_IMAGE_URL,imageUrls);
        mTencent.shareToQzone((Activity)context, params, listener);
    }

微信常见问题:

        android微信分享中bmpToByteArray报错的解决方案

　1.微信分享网络图片 多看看官方demo里面有详细的用法  ,这里加线程是为了不在主线程中加载网络图片。（不然会报异常）

 /*
     * 分享链接网络图片链接
     */
    private void shareWebPage(final ShareContent shareContent, final int shareType) {

        new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    WXWebpageObject webpage = new WXWebpageObject();
                    webpage.webpageUrl = shareContent.getURL();
                    WXMediaMessage msg = new WXMediaMessage(webpage);
                    msg.title = shareContent.getTitle();
                    msg.description = shareContent.getContent();
        //          Bitmap thumb = BitmapFactory.decodeResource(mContext.getResources(), shareContent.getPictureResource());
                    Bitmap bmp = BitmapFactory.decodeStream(new URL(shareContent.getPictureUrl()).openStream());
                    Bitmap thumb = Bitmap.createScaledBitmap(bmp, THUMB_SIZE, THUMB_SIZE, true);
                    bmp.recycle();
                    if (thumb == null) {
                        Toast.makeText(mContext, "图片不能为空", Toast.LENGTH_SHORT).show();
                    } else {
                        msg.thumbData = Util.bmpToByteArray(thumb, true);
                    }
                    SendMessageToWX.Req req = new SendMessageToWX.Req();
                    req.transaction = buildTransaction("webpage");
                    req.message = msg;
                    req.scene = shareType;
                    mWXApi.sendReq(req);
                }catch (Exception e){
                    e.printStackTrace();
                }
            }
        }).start();
    }

2.集成微信登录和微信分享的返回码的地方区分。

// 第三方应用发送到微信的请求处理后的响应结果，会回调到该方法
    @Override
    public void onResp(BaseResp resp) {
        String result = "";
        if (resp != null) {
            resp = resp;
        }
        switch (resp.errCode) {
            case BaseResp.ErrCode.ERR_OK:
　　　　　　　　　　// 这里可以使用 官方API调用 resp.getType() 获取是登录后返回还是分享后返回 登录返回为1 分享返回为2
                if(resp.getType() == WE_LOGIN) {
                    result = "登录成功";
                    Toast.makeText(this, result, Toast.LENGTH_LONG).show();
                    String code = ((SendAuth.Resp) resp).code;
                    mIWxData.getCode(code);
                }else if(resp.getType() == WE_SHARE){
                    result = "分享成功";
                    Toast.makeText(this, result, Toast.LENGTH_LONG).show();
                }
                finish();
                break;
            case BaseResp.ErrCode.ERR_USER_CANCEL:
                result = "取消";
                Toast.makeText(this, result, Toast.LENGTH_LONG).show();
                LoadDialog.dismiss(this);
                finish();
                break;
            case BaseResp.ErrCode.ERR_AUTH_DENIED:
                result = "登录被拒绝";
                Toast.makeText(this, result, Toast.LENGTH_LONG).show();
                finish();
                break;
            default:
                result = "取消登录";
                Toast.makeText(this, result, Toast.LENGTH_LONG).show();
                finish();
                break;
        }
    }

 3.分享时出现hit push hold 

解决办法是：原因是你分享的微信账号在其他手机登陆了，但是本机还没有退出登陆，导致没有权限分享。重新进入微信并登陆就好了。

示例集成微信：

注意：关于放入SDK库文件我就不说了，下面是放入后的代码说明

 1.在android 的Application 中注册微信 （注意我只是展示了application中关于微信的代码 ，不代表里面就这些代码，当然还有其他的代码）

    /**
     * 微信API
     */
    public static IWXAPI api;
    /**
     * 初始化微信
     */
    private void registWX() {
        //通过WXAPIFactory工厂
        api = WXAPIFactory.createWXAPI(this,WX_APP_ID,false);
        api.registerApp(WX_APP_ID);
    }

2.先集成微信分享  可以编写微信管理类，是参考的上面博客中的内容，直接拿来用然后自己按自己需求改了改的

import android.graphics.Bitmap;

4.集成微信登录

首先做的还是上文第1点的内容

然后开始代码

5.调用的地方

        if(!NetworkUtils.isnetWorkAvilable()){
            ToastUtil.showShort(this,"暂无网络连接");
            return;
        }

//        WXapi = WXAPIFactory.createWXAPI(this, WXEntryActivity.WX_APP_ID, true);
//        WXapi.registerApp(WXEntryActivity.WX_APP_ID);
        WXapi = McvApplication.api;

        // 判断是否安装了微信客户端
        if (!WXapi.isWXAppInstalled()) {
            ToastUtil.showShort(this, "您还未安装微信客户端！");
            return;
        }

        LoadDialog.show(this,"正在打开微信..."); //弹出框

　　　　// 上面写的用来获取wechatCode的回调接口 设置进去
        WXEntryActivity.setIWxData(new WXEntryActivity.IWxData() {
            @Override
            public void getCode(String code) {
                //请求本地微信接口
//                ToastUtil.showShort(RegisterOneActivity.this,code);

                mLoginManager.weChatLogin(code);

            }
        });
        SendAuth.Req req = new SendAuth.Req();
        req.scope = "snsapi_userinfo";
        req.state = "com";
        WXapi.sendReq(req);
    }
