Question

我们有办法检查奥恩的网络连接类型(无论是3G、对面还是pr)。

我需要检查带宽率。我需要发出呼吁。为此,我需要检查带宽率。尤其是,只有我才能看到呼吁(发出呼吁)的选择。

我需要从方案上找到连接速度(移动数据链接的连接速度,EDGE)。

Answer 1

你可以从服务器下载一个已知的大小文件,并计算下载文件需要多长时间。然后,你带宽。简单但行之有效:

样本:

//Download your image
long startTime = System.currentTimeMillis();
HttpGet httpRequest = new HttpGet(new URL(urlString).toURI());
HttpClient httpClient = new DefaultHttpClient();
HttpResponse response = (HttpResponse) httpClient.execute(httpRequest);
long endTime = System.currentTimeMillis();

HttpEntity entity = response.getEntity();
BufferedHttpEntity bufHttpEntity;
bufHttpEntity = new BufferedHttpEntity(entity);

//You can re-check the size of your file
final long contentLength = bufHttpEntity.getContentLength();

// Log
Log.d(TAG, "[BENCHMARK] Dowload time :"+(endTime-startTime)+" ms");

// Bandwidth : size(KB)/time(s)
float bandwidth = contentLength / ((endTime-startTime) *1000);

Answer 2

This will Returns the current link speed in LINK_SPEED_UNITS.

但这一工作载于<代码>。 WIFI only

WifiManager wifiManager = Context.getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
if (wifiInfo != null) {
    Integer linkSpeed = wifiInfo.getLinkSpeed(); //measured using WifiInfo.LINK_SPEED_UNITS
}

Answer 3

履历

我们可以手工操作,也可以提供网络变化听众。

ConnectionQuality cq = ConnectionClassManager.getInstance().getCurrentBandwidthQuality();
