我在同步库中遇到了一些奇怪的问题。它在Android 9下方的设备上正常工作，但我的代码无法对URL进行休息。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：

我有双检查WiFi连接和其他电话设置，一切似乎都很好，我与ADB Shell连接并尝试在此服务器URL上ping并在Android 9手机上获得响应，但是通过上述代码，我无法制作一个仅在Android 9手机上致电。有人可以知道吗？
在新的Android版本上禁用清晰的文本流量
从Android 9(API级别28(开始，默认情况下禁用了ClearText支持。
更改您的AndroidManifest
<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
<uses-permission android:name="android.permission.INTERNET" />
<application
...
android:usesCleartextTraffic="true"
...>
...
</application>
资源：Android 8：ClearText HTTP流量不允许
这与Android 9中的SSL执行有关。我创建了一个适当的SSLFACTORY，并使用Trustmanager使用此帖子来解决此问题：
