Question

我在SyncHttpClient库中遇到了一些奇怪的问题。它在android 9以下的设备上运行良好，但是我的代码无法对URL进行其余调用。这是我的示例代码：

import com.loopj.android.http.*;

    AsyncHttpClient client = new SyncHttpClient();
                try {
                    KeyStore trustStore = MySSLSocketFactory.getKeystore();
                    MySSLSocketFactory sf = new MySSLSocketFactory(trustStore);
                    sf.setHostnameVerifier(MySSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
                    client.setSSLSocketFactory(sf);
                    client.setTimeout(600000);
                    client.setConnectTimeout(10000);
                } catch (Exception e) {
                    Log.e(TAG, "error while using truststore for apk instllation..");
                }

                // method which making a rest call
                 private void checkId(final String myUrl, final String name, final Integer version) {
        RequestParams requestParams = new RequestParams("name", name, "version", version);

        client.post(myUrl, requestParams, new JsonHttpResponseHandler() {
            @Override
            public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
                try {
                    if (response == null) {
                        Log.i(TAG, "check_version response is null nothing to download.");
                        return;
                    }
                      //success

                } catch (JSONException e) {
                    Log.e(TAG, "Error while parsing json", e);
                }
            }

            @Override
            public void onFailure(int statusCode, Header[] headers, String res, Throwable throwable) {
                super.onFailure(statusCode, headers, res, throwable);
                Log.e(TAG, "Failed to check id " + myUrl + ", status " + statusCode + " error: "+throwable.getMessage());
            }
        });
    }

这是一个例外：

我已经仔细检查了WIFI连接和其他电话设置，而且一切似乎都很好，我也连接了adb shell，并尝试ping此服务器URL并在android 9手机上获得响应，但通过上述代码我无法做出仅在android 9手机上致电。有人可以提供任何线索吗？

Answer 1

在新的Android版本上禁用了纯文本流量

从Android 9（API级别28）开始，默认情况下禁用明文支持。

更改您的AndroidManifest

Table1.ID

资源：Android 8: Cleartext HTTP traffic not permitted

Answer 2

这与android 9中的SSL实施有关。我创建了一个正确的SSLFactory，并使用trustmanager通过以下post解决此问题：

AsyncHttpClient无法连接到Android 9上的发布URL
