检查 Android 中的带宽速率

发布于 2024-12-17 13:03:16 字数 164 浏览 2 评论 0原文

我们可以选择检查 Android 中的网络连接类型（无论是 3G、edge 还是 gprs）。

我需要检查带宽速率。我需要拨打电话。为此，我需要检查带宽速率。仅在特定带宽之上，我需要使呼叫选项可见（以发起呼叫）。

我需要以编程方式查找连接速度（移动数据链路、EDGE 的连接速度）。

您可以从服务器下载已知大小的文件，并计算下载它需要多长时间。然后你就有了你的带宽。简单但有效:)

示例，未经测试：

//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);

You can download a known-size file from your server, and calculate how long did it take to download it. Then you have your bandwidth. Simple but works :)

Sample, not tested :

//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);

这将返回LINK_SPEED_UNITS 中的当前链接速度。

，但这仅适用于WIFI

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

This will Returns the current link speed in LINK_SPEED_UNITS.

but this work for 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
}
