我正在制作一个程序,它使用PHP页面连接到数据库,然后通过JSON解析信息。问题是,我在负责网络通信的AsyncTask上遇到了RuntimeException。我正在使用物理安卓设备进行测试。
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("URL");
try {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair("password", "******"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Error appears on this line
HttpResponse response = httpclient.execute(httppost);
//JSON Parsing here
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
catch (Throwable t)
{
CharSequence message = "Request failed: " + t.toString();
Toast.makeText(getApplicationContext(), message, Toast.LENGTH_LONG).show();
}

**只需检查您在Android Manifest文件中添加以下权限行的位置。 **
<uses-permission android:name="android.permission.INTERNET" />
**它必须是清单标记的子元素。您可能已将其添加到应用程序标记下。 **
