Question

我在HTTPResponseCache的实施方面面临一个问题。该实现在Galaxy S2设备中的Android 4.0.3版本中非常有效，其中相同的代码对于使用Android 4.0.4版本的Galaxy S3设备不起作用。

在阅读InputStream时，它会抛出在飞行模式下找不到的异常URL。如果某个机构有想法，请分享。

感谢。

请在Galaxy S3上发送请求时找到和平代码和异常。

    private void executeGETRequest(){
        InputStream inStream = null;
        String result = "";
        try{
        URL url = new URL("http://example.com/target");

        HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();       
        urlConnection.setUseCaches(true);
        urlConnection.addRequestProperty("Client-Identity", getHeader());
        urlConnection.addRequestProperty("Cache-Control", "max-stale=" + NetworkConstants.MAX_STALE_TIME);       
        urlConnection.setRequestProperty("Accept", "application/json");

        inStream = urlConnection.getInputStream();//Point where the error occur

        if(null != inStream){
            result = convertStreamInToString(inStream);
            //result output
        }
        result = null;
        inStream.close();
        inStream = null;       
        }catch(Exception e){
        e.printstack();
        }
    }

，例外是

由于

HttpResponseCache不适用于Galaxy S3
