我今天试了一下，可以建立Socket连接了，也能进行数据收发。js代码如下:
```javascript
function testSocket(){
if (plus.os.name == "Android") {
var Socket = plus.android.importClass("java.net.Socket");
var PrintWriter = plus.android.importClass("java.io.PrintWriter");
var BufferedWriter = plus.android.importClass("java.io.BufferedWriter");
var OutputStreamWriter = plus.android.importClass("java.io.OutputStreamWriter");
var BufferedReader = plus.android.importClass("java.io.BufferedReader");
var InputStreamReader = plus.android.importClass("java.io.InputStreamReader");

var socket = new Socket("192.168.23.8", 8080);

var outputStreamWriter = new OutputStreamWriter(socket.getOutputStream());
var bufferWriter = new BufferedWriter(outputStreamWriter);
var out = new PrintWriter(bufferWriter, true);
out.println("Conneted...");

var inputStreamReader = new InputStreamReader(socket.getInputStream());
var br = new BufferedReader(inputStreamReader);
var msg = br.readLine();

//while(true)
{
if(msg != null)
{
console.log(msg);
}
//msg = br.readLine();
}
}
//console.log(mac);
alert("Done");
}
```

感谢分享，真机测试可运行。
“获取手机内存信息”方法代码有点问题，正确代码如下：
``` javascript
/*获取手机内存信息*/
function getMemorySize() {
var memoryInfo = '';
if (plus.os.name == "Android") {
var Context = plus.android.importClass("android.content.Context");
var ActivityManager = plus.android.importClass("android.app.ActivityManager");
var mi = new ActivityManager.MemoryInfo();
var activityService = plus.android.runtimeMainActivity().getSystemService(Context.ACTIVITY_SERVICE);
activityService.getMemoryInfo(mi);
memoryInfo = mi.plusGetAttribute("availMem");
}
return memoryInfo;
}
```
**旧版本HBuilder runtime获取属性值方法plusGetAttribute返回的值不正确，需要更新到最新版本**

@DCloud_App_Array 這個示例代码分享給大家

這個問題就自行回答了 ：P

HTML5+ API 的推送，請參考 [Push模块管理推送消息功能](http://dcloud.io/docs/api/zh_cn/push.shtml)
Dcloud也集成了個推的功能，請參考 [推送插件配置](http://ask.dcloud.net.cn/docs/#http://ask.dcloud.net.cn/article/92) 、 [推送插件开发指南](http://ask.dcloud.net.cn/docs/#http://ask.dcloud.net.cn/article/34)

而原生的文檔，請參考谷歌的 [Notification](http://developer.android.com/reference/android/app/Notification.html) 、 [Notification.Builder](http://developer.android.com/reference/android/app/Notification.Builder.html) 、[NotificationManager](http://developer.android.com/reference/android/app/NotificationManager.html)

代碼如下，效果比較接近5+ 的Push
```javascript
var NotifyID = 1;
var Context = plus.android.importClass("android.content.Context");
var main = plus.android.runtimeMainActivity();
var Noti = plus.android.importClass("android.app.Notification");
var NotificationManager = plus.android.importClass("android.app.NotificationManager");
var nm = main.getSystemService(Context.NOTIFICATION_SERVICE)
var Notification = plus.android.importClass("android.app.Notification");
var mNotification = new Notification.Builder(main);
mNotification.setOngoing(true);
mNotification.setContentTitle("Hbuilder")
mNotification.setContentText("MUI & 5+ 大好！")
mNotification.setSmallIcon(17301620)
mNotification.setTicker("PadInfo")

mNotification.setNumber(10)
var mNb = mNotification.build()
nm.notify(NotifyID , mNb);
```

實際效果：
** 插入的附件 **

這個可以直接實現本地推送，固定在通知栏。
如果要可以从通知栏刪掉的，請去除掉 mNotification.setOngoing(true) 這行代碼即可

用Native.js可以实现此功能：
``` javascript
var main = plus.android.runtimeMainActivity();
main.moveTaskToBack(false);
```

**注意：请更新HBuilder到5.2.0以上版本**

```javascript
var mainActivity = plus.android.runtimeMainActivity();
var Settings= plus.android.importClass("android.provider.Settings");
console.log(Settings.Secure.getString(mainActivity.getContentResolver(),Settings.Secure.ANDROID_ID));
```

@DCloud_App_Array

```javascript
var AVCaptureDevice = plus.ios.importClass("AVCaptureDevice");
var authStatus =AVCaptureDevice.authorizationStatusForMediaType ("vide");
```

向IOS同事请教，已解决该问题。
```javascript
var AVAudioSession = plus.ios.importClass("AVAudioSession");
var AVSpeechSynthesizer = plus.ios.importClass("AVSpeechSynthesizer");
var AVSpeechUtterance = plus.ios.importClass("AVSpeechUtterance");
var AVSpeechSynthesisVoice = plus.ios.import("AVSpeechSynthesisVoice");
AVAudioSession.sharedInstance().setCategoryerror("AVAudioSessionCategoryPlayback",null);
var sppech = new AVSpeechSynthesizer();
var utterance = AVSpeechUtterance.speechUtteranceWithString("共产主义接班人");
utterance.plusSetAttribute("rate",0.3);
sppech.speakUtterance(utterance);
//停止
sppech.stopSpeakingAtBoundary(0)
//暂停
sppech.pauseSpeakingAtBoundary(0);
//继续
sppech.continueSpeaking(0);
plus.ios.deleteObject(voice);
plus.ios.deleteObject(utterance);
plus.ios.deleteObject(sppech);
plus.ios.deleteObject(AVAudioSession);
```
**需iOS7.0及以上系统支持此功能**
**Android平台参考[http://ask.dcloud.net.cn/question/6473](http://ask.dcloud.net.cn/question/6473)**

更新：5+已提供蓝牙，参考[http://www.html5plus.org/doc/zh_cn/bluetooth.html](http://www.html5plus.org/doc/zh_cn/bluetooth.html) 注意需要最新版HBuilderX

需要对你的代码进行修正如下：
main = plus.android.runtimeMainActivity();
Context = plus.android.importClass("android.content.Context");
BManager = main.getSystemService(Context.BLUETOOTH_SERVICE);
plus.android.importClass(BManager);//引入相关的method函数
BAdapter = BManager.getAdapter();
plus.android.importClass(BAdapter);//引入相关的method函数，这样之后才会有isEnabled函数支持
if(!BAdapter.isEnabled()) {
BAdapter.enable();
}

同时建议，由于BluetoothManager.getAdapter()属于level18版本，在18以下版本肯定是不能使用的。还请使用BluetoothAdapter.getDefaultAdapter() 方式实现。

更新=====
plus.webview补充了截屏方法，这个效率更高，而且ios、Android都可以直接用。[http://html5plus.org/doc/zh_cn/webview.html#plus.webview.WebviewObject.draw](http://html5plus.org/doc/zh_cn/webview.html#plus.webview.WebviewObject.draw)

console.log(e.message);

console.log("截图字节长度："+str.length());
document.getElementById("imgCapture").src = "data:image/png;base64," + str.toString();

由于Android系统tts不支持中文，使用科大讯飞文字转语音功能，使用如此功能时，需要保证manifest.json中permissions节点含有speech节点(如"Speech": {"description": "管理语音识别插件" })。

```javascript

var main = plus.android.runtimeMainActivity();
var SynthesizerPlayer = plus.android.importClass('com.iflytek.speech.SynthesizerPlayer');
var play = SynthesizerPlayer.createSynthesizerPlayer(main,'appid=5177d8fe');
play.playText('水果',null,null);
```
