从在线数据库获取数据

Question

protected Void doInBackground(Void... params) {
    ArrayList<NameValuePair> dataToSend = new ArrayList<>();
    dataToSend.add(new BasicNameValuePair("Name", user.name));
    return null;
}

my activity was unable to import NameValuePair data model thats why i was getting this issue, i think i have not imported the proper library for this function.

Answer 1

The IDE can't find a class with name "NameValuePair".

It seems that there is an Interface org.apache.http.NameValuePair which is deprecated for API levels 22 and higher.

So, as suggested in the Preview (Behavior Changes) for Android M you should work with 'HttpURLConnection' or

declare the following compile-time dependency in your build.gradle file:

android {
useLibrary 'org.apache.http.legacy'
}
