android - 如何检查android中的慢速网络连接

Question

如果网络连接很慢，我必须显示一个页面

我正在使用此代码检查网络

   ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo info = cm.getActiveNetworkInfo();
    if (info.getType() == ConnectivityManager.TYPE_WIFI) {
        Toast.makeText(MainActivity.this,"wifi",Toast.LENGTH_LONG).show();


        // do something
    } else if (info.getType() == ConnectivityManager.TYPE_MOBILE) {


        // check NetworkInfo subtype
        if (info.getSubtype() == TelephonyManager.NETWORK_TYPE_GPRS) {
            Toast.makeText(MainActivity.this,"mobile 100kbps",Toast.LENGTH_LONG).show();
            // Bandwidth between 100 kbps and below
        } else if (info.getSubtype() == TelephonyManager.NETWORK_TYPE_EDGE) {
            Toast.makeText(MainActivity.this,"mobile 50-100kbps",Toast.LENGTH_LONG).show();

            // Bandwidth between 50-100 kbps
        } else if (info.getSubtype() == TelephonyManager.NETWORK_TYPE_EVDO_0) {
            Toast.makeText(MainActivity.this,"mobile 400-1000kbps",Toast.LENGTH_LONG).show();

            // Bandwidth between 400-1000 kbps
        } else if (info.getSubtype() == TelephonyManager.NETWORK_TYPE_EVDO_A) {
            Toast.makeText(MainActivity.this,"mobile 600-1400kbps",Toast.LENGTH_LONG).show();

            // Bandwidth between 600-1400 kbps
        }

它显示的是wifi网络但我需要慢速 wifi 网络的代码。请帮助我是否有任何代码来检查慢速 wifi 网络。

使用以下方法检查wifi级别:

public int getWifiLevel()
{
    WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
    int linkSpeed = wifiManager.getConnectionInfo().getRssi();
    int level = WifiManager.calculateSignalLevel(linkSpeed, 5);
    return level;
}

根据 wifi 级别或链接速度，您可以决定它是低连接还是高连接互联网。
