Phonegap学习点滴（2） -- 网络状态检测 http://blog.csdn.net/x251808026/article/details/16992943
方法一：在MainActivity中检查然后传递参数到html
public class MainActivity extends DroidGap {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo info = cm.getActiveNetworkInfo();
if (info != null){
if (info.isAvailable()){
super.loadUrl("http://www.baidu.com",6000);
}else{
super.loadUrl(Config.getStartUrl());
}
}else{
super.loadUrl(Config.getStartUrl());
}
}
}
方法二：直接在html中检测
function checkConnection() {
var networkState = navigator.network.connection.type;
var states = {};
states[Connection.UNKNOWN] = 1;
states[Connection.ETHERNET] = 2;
states[Connection.WIFI] = 3;
states[Connection.CELL_2G] = 4;
states[Connection.CELL_3G] = 5;
states[Connection.CELL_4G] = 6;
states[Connection.NONE] = 0;
alert('Connection type: ' + states[networkState]);
}
