android开发中wifi模块移植

最近刚上一个项目，是关于在机智平台上使用esp8266芯片进行wifi通信控制，其实我对esp8266这块不是很熟悉，因为以前做的事zigbee的，现在使用wifi对智能灯进行控制。我在移植中碰到的问题做一简单总结。首先，将esp8266的wifi模块demo全部文件（espressif文件夹所有）的复制到机智云的app中，根据demo的Activity的实现在AirlinkActivity.java中写一个异步任务的内部类，重写doInBackground方法

@Override
protected Void doInBackground(String... params) {

String strSsid = params[0];
String strBssid = params[1];
String strPassword = params[2];
String isSsidHiddenStr = params[3];
boolean isSsidHidden = false;
if(isSsidHiddenStr.equals("YES"))
{
isSsidHidden = true;
}

Log.i(TAG, "strSsid = :" + strSsid + ", strBssid = :" + strBssid
+ ", strPassword = :" + strPassword + ", isSsidHiddenStr = :" + isSsidHiddenStr);

new EsptouchTask(strSsid, strBssid, strPassword, isSsidHidden, AirlinkActivity.this).executeForResult();
return null;
}

在

new EsptouchTask(strSsid, strBssid, strPassword, isSsidHidden, AirlinkActivity.this).executeForResult();一定调用executeForResult()方法。

完整demo_Activity

移植的部分代码：

/*** start smartlink wifi*/private void startSmartlink(){secondleft = 60;String strBssid = mWifiAdmin.getWifiConnectedBssid();Log.i(TAG, "strBssid :" + strBssid);boolean isSsidHidden = false;if(isSsidHiddenStr.equals("YES")){isSsidHidden = true;}Log.i(TAG, "mBtnConfirm is clicked, strBssid = " + strBssid + "strSsid = " + strSSid+ ", " + " strPassword = " + strPsw);tvTick.setText(secondleft + "");showLayout(UI_STATE.Setting);timer = new Timer();timer.schedule(new TimerTask() {@Overridepublic void run() {Log.i(TAG, " connect ");handler.sendEmptyMessage(handler_key.TICK_TIME.ordinal());}}, 1000, 1000);new EsptouchAsyncTask().execute(strSSid, strBssid, strPsw, isSsidHiddenStr);}/*** 内部类：异步处理wifi信息*/private class EsptouchAsyncTask extends AsyncTask<String, Void, Void> {@Overrideprotected void onPreExecute() {super.onPreExecute();}@Override
protected Void doInBackground(String... params) {

String strSsid = params[0];
String strBssid = params[1];
String strPassword = params[2];
String isSsidHiddenStr = params[3];
boolean isSsidHidden = false;
if(isSsidHiddenStr.equals("YES"))
{
isSsidHidden = true;
}

Log.i(TAG, "strSsid = :" + strSsid + ", strBssid = :" + strBssid
+ ", strPassword = :" + strPassword + ", isSsidHiddenStr = :" + isSsidHiddenStr);

new EsptouchTask(strSsid, strBssid, strPassword, isSsidHidden, AirlinkActivity.this).executeForResult();
return null;
}@Overrideprotected void onProgressUpdate(Void... values) {super.onProgressUpdate(values);}}

具体的实现要看需要什么条件，可能开发的功能不一样。
