信鸽推送的使用

最近在看推送方面的知识，用的是信鸽推送主要是因为后台用的是信鸽

推送用第三方推送，也就是在客户端建一个广播接收器，当服务器发送消息时发送到信鸽，信鸽再发送一次，广播接受器接受下；

我实现的功能比较简单，当app在运行状态时，会在主页展示一个弹窗展示推送的消息；如果app不在运行状态且service没被销毁就展示默认的通知

那么如何在主页展示弹窗：当广播接受器收到我要的消息时，用观察者模式，收到消息在发送个消息个主界面

官方的Demo连接：http://xg.qq.com/xg/help/ctr_help/download

修改后Demo的地址：http://download.csdn.net/detail/qq_29774291/9635735

1.先按照官网的例子添加好权限及服务有些服务要改成自己的包名；

2.把官网的广播接受器先复制到自己的项目中，再在清单文件中添加；

3.随后添加从官网给出的3个AccessKey了

<meta-data android:name="com.tencent.rdm.uuid" android:value="eb5fa555d70c3246a4944f55be8c266b" />
        <!-- 【必须】 请将YOUR_ACCESS_ID修改为APP的AccessId，“21”开头的10位数字，中间没空格 -->
        <!-- 【必须】 请修改为APP的AccessId，“21”开头的10位数字，中间没空格 -->
        <meta-data
            android:name="XG_V2_ACCESS_ID"
            android:value="2100219302" />
        <!-- 【必须】 请修改为APP的AccessKey，“A”开头的12位字符串，中间没空格 -->
        <meta-data
            android:name="XG_V2_ACCESS_KEY"
            android:value="A15KJ71W9ELC" />

4.现在在主界面中注册信鸽推送主要是获取一个token，然后可以上传给服务端，现在服务器就可以给你发送消息了；当然从信鸽官方后台可以发送消息，但是从信鸽后台发送的消息有时会接受不到，这点做的完全不及极光推送好

XGPushConfig.enableDebug(this, true);这句发布的时候记得改为false或删除

//信鸽start
        private String token;
        private Message message = null;
    private void XGInit() {
        // TODO Auto-generated method stub
        XGPushConfig.enableDebug(this, true);
        // 如果需要知道注册是否成功，请使用registerPush(getApplicationContext(),
        // XGIOperateCallback)带callback版本
        // 如果需要绑定账号，请使用registerPush(getApplicationContext(),account)版本
        // 具体可参考详细的开发指南
        // 传递的参数为ApplicationContext
        //Context context = getApplicationContext();
        //1.获取设备的Token
        Handler handler = new HandlerExtension(MainActivity.this);
        message = handler.obtainMessage();
        XGPushManager.registerPush(getApplicationContext(), new XGIOperateCallback() {
            
            @Override
            public void onSuccess(Object data, int flag) {
                // TODO Auto-generated method stub
                Log.d("jiejie", "+++ register push sucess. token:" + data  + "  " + flag);
                token = data + "";
                message.obj = "+++ register push sucess. token:" + data;
                System.out.println(token);
                message.sendToTarget();
            }
            
            @Override
            public void onFail(Object data, int errCode, String msg) {
                // TODO Auto-generated method stub
                Log.d("jiejie", "+++ register push fail. token:" + data
                        + ", errCode:" + errCode + ",msg:"
                        + msg);
                message.obj = "+++ register push fail. token:" + data
                        + ", errCode:" + errCode + ",msg:" + msg;
                message.sendToTarget();
            }
        });
    }
    private static class HandlerExtension extends Handler{
        WeakReference<MainActivity> mActivity;
        HandlerExtension(MainActivity activity) {
            mActivity = new WeakReference<MainActivity>(activity);
        }
        @Override
        public void handleMessage(Message msg) {
            // TODO Auto-generated method stub
            super.handleMessage(msg);
            MainActivity theActivity = mActivity.get();
            if(theActivity == null){
                theActivity = new MainActivity();
            }
            if(msg != null){
                Log.d(Constants.LogTag, msg.obj.toString());
                System.out.println("ddd"+msg.obj.toString());
            }
        }
    }

5.修改广播接受器中的onTextMessage方法，当消息发送来时，将消息发送到主界面，不展示通知

不过你先要知道你app是否正在运行状态

 /**
     * 判断是否运行在前台
     * 
     * @param context
     * @return
     */
    public static boolean isRunningForeground(Context context) {
        String packageName = getPackageName(context);
        String topActivityClassName = getTopActivityName(context);
        Log.d("TAG", "packageName=" + packageName + ",topActivityClassName=" + topActivityClassName);
        if (packageName != null && topActivityClassName != null && topActivityClassName.startsWith(packageName)) {
            Log.d("TAG", "---> isRunningForeGround");
            return true;
        } else {
            Log.d("TAG", "---> isRunningBackGround");
            return false;
        }
    }

    // 方法2、通过RunningAppProcessInfo类判断（不需要额外权限）：

    public static boolean isBackground(Context context) {
        ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
        List<RunningAppProcessInfo> appProcesses = activityManager.getRunningAppProcesses();
        for (RunningAppProcessInfo appProcess : appProcesses) {
            if (appProcess.processName.equals(context.getPackageName())) {
                if (appProcess.importance == RunningAppProcessInfo.IMPORTANCE_BACKGROUND) {
                    Log.i("后台", appProcess.processName);
                    return true;
                } else {
                    Log.i("前台", appProcess.processName);
                    return false;
                }
            }
        }
        return false;
    }

6.通知EventBus来实现观察者模式在广播接收器中发送消息

 // 消息透传
    @Override
    public void onTextMessage(Context context, XGPushTextMessage message) {
        String text = "收到消息:" + message.toString();
        EventBus.getDefault().post(text);
        System.out.println(text);
        // 获取自定义key-value
        PushTextMessage pushTextMessage = new PushTextMessage();

        String title = message.getTitle();
        String content = message.getContent();
        pushTextMessage.setTitle(title);
        pushTextMessage.setContent(content);       
        String customContent = message.getCustomContent();
        if (customContent != null && customContent.length() != 0) {
            try {
                // JSONObject obj = new JSONObject(customContent);
                // // key1为前台配置的key
                // if (!obj.isNull("key")) {
                // String value = obj.getString("key");
                // LogUtils.log(LogTag, "get custom value:" + value);
                // }
                CustomContent custom = com.alibaba.fastjson.JSONObject.parseObject(customContent, CustomContent.class);
                if (custom != null) {
                    pushTextMessage.setCustomContent(custom);
                }

                // ...
            } catch (Exception e) {
                System.out.println(e + "d");
                e.printStackTrace();
            }
        }
        show(context, text);
        Log.d("jiejie", "pushTextMessage:" + pushTextMessage);
       // EventBus.getDefault().post(pushTextMessage);
        try {
            // APP自主处理消息的过程...
            boolean isForeground = AppUtil.isRunningForeground(context);
            Log.d("jiejie", isForeground + "d");
            if (isForeground) {
                EventBus.getDefault().post(pushTextMessage);
            } else {
                notify(context, title, content);
            }
        } catch (Exception e) {
            System.out.println(e  + "ddd");
            e.printStackTrace();
        }

7.在主界面中接受EventBus发送的消息，展示一个弹窗

@Subscribe
    public void onMessageReviced(final PushTextMessage pushTextMessage){
        Log.d("jiejie", "好"  + "  标题" +pushTextMessage.getTitle() + " 内容：" +pushTextMessage.getContent()  + "CustomContent" + pushTextMessage.getCustomContent().getCmd());
        if(pushTextMessage != null){
            showAlertDialog(this, pushTextMessage);
        }
    }
    private void showAlertDialog(Context context,PushTextMessage text){
        AlertDialog.Builder dialog = new AlertDialog.Builder(context);
        dialog.setTitle("推送的标题");
        dialog.setMessage(text.getContent());
        dialog.setPositiveButton("确认", new DialogInterface.OnClickListener() {
            
            @Override
            public void onClick(DialogInterface arg0, int arg1) {
                // TODO Auto-generated method stub
                
            }
        });
        AlertDialog mDialog = dialog.create();
        mDialog.show();
    }
    
    @Override
    protected void onDestroy() {
        // TODO Auto-generated method stub
        super.onDestroy();
        EventBus.getDefault().unregister(this);
    }
