android 获取宽带类型,Android 网络类型判断

在Android中经常用到网络状态和网络类型，不如网络为WIFI是做某一操作，网络为数据流量时做另一个操作。

以下是获取网络类型的示例代码：

private void checkNetworkConnection() {

String TAG = "Basic Network Demo";

// Whether there is a Wi-Fi connection.

boolean wifiConnected = false;

// Whether there is a mobile connection.

boolean mobileConnected = false;

// BEGIN_INCLUDE(connect)

ConnectivityManager connMgr =

(ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

NetworkInfo activeInfo = connMgr.getActiveNetworkInfo();

if (activeInfo != null && activeInfo.isConnected()) {

wifiConnected = activeInfo.getType() == ConnectivityManager.TYPE_WIFI;

mobileConnected = activeInfo.getType() == ConnectivityManager.TYPE_MOBILE;

if (wifiConnected) {

Log.i(TAG, "The active connection is wifi.");

} else if (mobileConnected) {

Log.i(TAG, "The active connection is mobile.");

}

} else {

Log.i(TAG, "No wireless or mobile connection.");

}

// END_INCLUDE(connect)

}
