我有以下代码：
BasicHttpResponse send(String message) throws KeyStoreException, IOException, NoSuchAlgorithmException, UnsupportedEncodingException, AuthenticationException, CertificateException, KeyManagementException, UnrecoverableKeyException {
Log.d(context.getString(R.string.app_name), "SOAP: " + message);
//SSL
final KeyStore keyStore = KeyStore.getInstance("BKS");
keyStore.load(context.getResources().openRawResource(R.raw.ipex), "xxx".toCharArray());
final SSLSocketFactory ssl = new SSLSocketFactory(keyStore);
ssl.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
http.getConnectionManager().getSchemeRegistry().register(new Scheme("https", ssl, 443));
//SOAP POST
post.setHeader("Content-Type", "application/soap+xml; charset=utf-8");
http.modifyRequestToAcceptGzipResponse(post);
final StringEntity entity = new StringEntity(message.toString(), HTTP.UTF_8);
entity.setContentType("text/xml");
post.setEntity(entity);
//Basic HTTP authentication
post.setHeader(new BasicScheme().authenticate(credentials, post));
//Send request
BasicHttpResponse response = null;
final byte max = 5;
for (byte i = 1; response == null || (i <= max && response.getStatusLine().getStatusCode() != HttpStatus.SC_OK); i++) {
Log.d(context.getString(R.string.app_name), String.format("SOAP: %d/%d", i, max));
response = (BasicHttpResponse) http.execute(post);
Log.d(context.getString(R.string.app_name), response.getStatusLine().toString());
}
//Unpack response
final BasicHttpEntity ungzipped = new BasicHttpEntity();
ungzipped.setContent(http.getUngzippedContent(response.getEntity()));
response.setEntity(ungzipped);
Log.v(context.getString(R.string.app_name), "SOAP: return");
return response;
}
它始终以3.循环结束，并将其放入logcat：

我不完全了解发生了什么。
我知道ANR是什么，以及如何避免它，我想我正在这样做，但是...... Android并不这么认为。
该应用由Activity和按钮组成。按钮会向ForegroundService发送消息（使用StartService() Intent）。然后ForegroundService创建准备SOAP消息的类，实例化SOAP类并启动AsyncTask以实际执行send()（如traces.txt中所示）。
所以，代码的HTTP部分正在AsyncTask中运行，那么为什么ANR ???
P上。 S.为什么5次尝试？ PHP SOAP服务器有时返回HTTP 500，SOAP响应说Bad Request，我们不知道原因。有什么想法吗？
答案 0 :(得分：2)
此错误通常与调用系统资源过快或不与线程同步有关。如果你正在做这两件事，试着尽量减少线程中的实际代码。
编辑现在，我查看了您的代码，您似乎陷入了僵局。使用你的线程周围的同步，你应该没问题
