I guess, you should acquire a WakeLock in order to finish your download, and then release it. Especially, if you're downloading a large file via a Wi-Fi connection, it is typical to acquire a WifiLock in order to keep radio awake.

On the other hand, you might (if you do not already) as well try <a href="http://developer.android.com/reference/android/app/DownloadManager.html" rel="nofollow">DownloadManager</a>. As <a href="http://developer.android.com/training/scheduling/wakelock.html" rel="nofollow">this official article on wakelocks</a> states,

"If your app is performing long-running HTTP downloads, consider using DownloadManager."

If you are using HttpConnection then increase Timeout

HttpURLConnection con = (HttpURLConnection) url.openConnection();

con.setReadTimeout(10000 );

OR

HttpConnectionParams.setSoTimeout(httpParameters, 10000); //

I'm not pretty sure this might be the issue but it's a possibility. You say this happens on low processor devices, it might happen that the remote servers upstream bitrate is that big that the client's downstream bitrate can't handle it, and as this happens with large files, after a certain amount of time the receiver device can't handle the bitrate, the <code>Socket</code> collapses and you get that timeout.

My suggestion is trying to implement a bandwith rate limiter. This way you can test whether the slow devices respond better to those long downloads, though they will be slower.

blocks|key|944272|text|要使用HTTP服务器，我强烈建议您使用Loopj库，它是一个可靠、简单且易于使用的库。正如文档所说，您可以像这样简单地下载文件：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|944273|AsyncHttpClient+client+=+new+AsyncHttpClient();

To work with a <code>HTTP</code> server I strongly suggest <a href="http://loopj.com/android-async-http/" rel="nofollow">Loopj</a> library to you, it's a reliable, simple and easy to use library.
as documentation said you can download a file simply like this:

<pre><code>AsyncHttpClient client = new AsyncHttpClient();
String[] allowedContentTypes = new String[] { "image/png", "image/jpeg" };
client.get("http://example.com/file.png", new BinaryHttpResponseHandler(allowedContentTypes) {
 @Override
 public void onSuccess(byte[] fileData) {
 // Do something with the file
 }
});
</code></pre>

I am downloading a large size zip file from server. I am getting following

<pre><code>06-11 21:45:18.789: I/System.out(8993): java.net.SocketException: recvfrom failed: ETIMEDOUT (Connection timed out)
</code></pre>

My application does not stop, but my downloading stops. This happens on hdpi android mobile specifically saying low processor devices. The downloading works fine on S3 and tablets. I am using simple FileOutputStream method to download the file.
