广播

一:网络监听广播

NetWorkReceiver mNetWorkReceiver = new NetWorkReceiver();
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
registerReceiver(mNetWorkReceiver, intentFilter);

广播内操作:

@Override
public void onReceive(Context context, Intent intent) {

    if (isNetworkConnected(context)) {
        MyLog.d( TAG,"网络已连接");
        mFTPManager.initHttp();

    } else {
        MyLog.d( TAG,"网络连接已断开");

    }
}

//网络是否有连接
public boolean isNetworkConnected(Context context) {
    if (context != null) {
        ConnectivityManager mConnectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo mNetworkInfo = mConnectivityManager.getActiveNetworkInfo();
        if (mNetworkInfo != null && mNetworkInfo.isAvailable()) {
            return mNetworkInfo.isAvailable();
        }
    }
    return false;
}

二:开机广播

(注:需开启过一次才能监听到)

<receiver android:name=".DeviceStateReceiver" >
    <intent-filter >
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")){

    //具体操作

}
