我使用Send类向php发送电子邮件但是出错

private class Send extends AsyncTask<String, String, String> {

    private InputStream is = null;
    private String url = "http://*****.com/sand.php";
    private String page_output = "";

    @Override
    protected String doInBackground(String... args) {

            try {
                    // Building Parameters
            List<NameValuePair> params = new ArrayList<NameValuePair>();
            params.add(new BasicNameValuePair("Email", ed_email.getText().toString()));

            // defaultHttpClient
            DefaultHttpClient httpClient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(url);
            httpPost.setEntity(new UrlEncodedFormEntity(params));

            HttpResponse httpResponse = httpClient.execute(httpPost);
            HttpEntity httpEntity = httpResponse.getEntity();
            is = httpEntity.getContent();
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        try {
            BufferedReader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"), 8);
            StringBuilder sb = new StringBuilder();

            String line = null;
            while ((line = reader.readLine()) != null)
            {
                sb.append(line + "\n");
            }
            is.close();
            page_output = sb.toString();

            Log.i("Ekhteraat app ControlPanel", "page_output --> " + page_output); ///<--------------------------|
        } catch (Exception e) {
            Log.e("Buffer Error", "Error converting result " + e.toString());
        }

        return page_output;
    }

    @Override
    protected void onPostExecute(String page_output) {
            pDialog.dismiss();
        try {

            myJSON=page_output;


        } catch (Exception e) {
            e.printStackTrace();
        }
   }
}

这是日志中的错误

Answer 1

将此添加到AndroidManifest.xml

<manifest xlmns:android...>
 ...
 <uses-permission android:name="android.permission.INTERNET" />
 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
 <application ...
</manifest>

这有帮助吗？
