实际上我在这里尝试从服务器下载多个图像，当我尝试从localhost下载图像时，它很好（在3秒内图像下载）。但是当我尝试从实际服务器下载它时，即使我的互联网连接非常快，它也需要很长时间（至少15秒）。图像的总大小不超过600 kb。
pool = Executors.newFixedThreadPool(SplitImages.length);
int length = 0;
for (String name : SplitImages) {
pool.submit(new DownloadImageSequencially(name,length));
length = length+1;
}
pool.shutdown();
try {
if(!pool.awaitTermination(15, TimeUnit.SECONDS))
{
Log.e("TASKS NOT COMPLETED","TASKS NOT COMPLETED");
}
}
catch (InterruptedException e)
{
Log.e("GONE","GONE");
}
以上代码调用下面的AsyncTask方法
private class DownloadImageSequencially implements Runnable
{
private String name;
private int indx;
public DownloadImageSequencially(String name,int indx) {
this.name = name;
this.indx=indx;
}
@Override
public void run() {
// surround with try-catch if downloadFile() throws something
downloadBitmap(name);
}
private void downloadBitmap(String url) {
// initilize the default HTTP client object
HttpClient client = new DefaultHttpClient();
//forming a HttoGet request
url = url.replace("\\","");
url = url.replace("\"","");
Log.e("url","url: "+url);
final HttpGet getRequest = new HttpGet(url);
Log.e("Masthan1","Masthan1");
//HttpPost getRequest = new HttpPost(url);
try {
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
Log.e("Masthan2","Masthan2");
HttpResponse response = client.execute(getRequest);
Log.e("Masthan3","Masthan3");
//check 200 OK for success
final int statusCode = response.getStatusLine().getStatusCode();
Log.e("Masthan4","Masthan4");
if (statusCode != HttpStatus.SC_OK) {
Log.w("ImageDownloader", "Error " + statusCode +
" while retrieving bitmap from " + url);
}
final HttpEntity entity = response.getEntity();
Log.e("Masthan5","Masthan5");
if (entity != null) {
InputStream inputStream = null;
try {
// getting contents from the stream
inputStream = entity.getContent();
Log.e("Masthan6","Masthan6");
// decoding stream data back into image Bitmap that android understands
bitmapArray[indx] = BitmapFactory.decodeStream(inputStream);
Log.e("Masthan7","Masthan7");
} finally {
Log.e("Masthan8","Masthan8");
if (inputStream != null) {
Log.e("Masthan9","Masthan9");
inputStream.close();
Log.e("Masthan10", "Masthan10");
}
entity.consumeContent();
Log.e("Masthan11", "Masthan11");
}
}
} catch (Exception e) {
// You Could provide a more explicit error message for IOException
getRequest.abort();
Log.e("ImageDownloader", "Something went wrong while" +

}
}
}
请帮助我为什么花这么长时间下载图片
