getting a 401 error on connecting to linkedin rest api with volley - android-volley

Question

I am trying to get email address of a user through linkedin's rest api. I am using volley for the request. But it shows 401 error. Can anyone help me through this. Below is the code. Access token is for r_basicprofile and r_emailaddress permissions
private static final String PROFILE_URL = "https://api.linkedin.com/v1/people/~:(id,first-name,last-name,email-address)";
private static final String OAUTH_ACCESS_TOKEN_PARAM ="oauth2_access_token";
private static final String QUESTION_MARK = "?";
private static final String EQUALS = "=";
private static final String HEADER_CONTENT_TYPE = "Content-Type";
private static final String HEADER_AUTHORIZATION = "Authorization";
private static final String HEADER_SRC = "x-li-src";
private static final String HEADER_LI_FORMAT = "x-li-format";
private static final String HEADER_LI_VER = "x-li-msdk-ver";
private static final String CONTENT_VALUE = "application/json";
private static final String HEADER_SRC_VALUE = "msdk";
private static final String HEADER_LI_FORMAT_VALUE = "json";
private TextView welcomeText;
private ProgressDialog pd;
String accessToken;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fflifind_friends);
welcomeText = (TextView) findViewById(R.id.activity_profile_welcome_text);
//Request basic profile of the user
SharedPreferences preferences = this.getSharedPreferences("user_info", 0);
accessToken = preferences.getString("accessToken", null);
if(accessToken!=null){
String profileUrl = getProfileUrl(accessToken);
Log.d("profile url", profileUrl);
// new GetProfileRequestAsyncTask().execute(profileUrl);
doServer(profileUrl);
}
}
private Map<String, String> getLiHeaders(String accessToken) {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put(HEADER_CONTENT_TYPE, CONTENT_VALUE);
headers.put(HEADER_AUTHORIZATION, "Bearer " + accessToken);
headers.put(HEADER_SRC, HEADER_SRC_VALUE);
headers.put(HEADER_LI_FORMAT, HEADER_LI_FORMAT_VALUE);
//headers.put(HEADER_LI_VER, BuildConfig.MSDK_VERSION);
return headers;
}
private static final String getProfileUrl(String accessToken){
String url = PROFILE_URL
+ QUESTION_MARK
+ OAUTH_ACCESS_TOKEN_PARAM + EQUALS + accessToken;
return url;
}
public void doServer(String url)
{
final ProgressDialog dialog = ProgressDialog.show(this, null, "Loading data ");
JsonObjectRequest jsObjRequest = new JsonObjectRequest
(Request.Method.POST, url, null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
dialog.dismiss();
Log.d("Jsonres-", response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
dialog.dismiss();
// TODO Auto-generated method stub
Log.d("error ","err");
Toast.makeText(getApplicationContext(), error.getLocalizedMessage(), Toast.LENGTH_LONG).show();
}
}){
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
return getLiHeaders(accessToken);
}
};
NetworkRequestQueue.getInstance(this).addToRequestQueue(jsObjRequest);
}

Use this method to get the profile information of linkedin account and define what you want from profile in PROFILE_LINK string mention below it's working fine for me.I hope its solved your problem.
public static final String HOST="https://api.linkedin.com/";
public static final String PROFILE_LINK=HOST+"v1/people/~:(id,firstName,lastName,picture-url)?oauth2_access_token=";
public static final String JSON_FORMAT=AMPERSAND+"format=json";
private void profileRequestAsyncTask(final String accessToken) {
showProgressDialog();
// Instantiate the RequestQueue.
RequestQueue queue = Volley.newRequestQueue(activity);
String url=PROFILE_LINK+accessToken+JSON_FORMAT;
// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
// Display the first 500 characters of the response string.
Log.e(TAG, "onResponse: "+response );
JSONObject dataAsJson= null;
try {
dataAsJson = new JSONObject(response);
String id=dataAsJson.getString("id");
String firstName=dataAsJson.getString("firstName");
String lastName=dataAsJson.getString("lastName");
String pictureUrl=dataAsJson.getString("pictureUrl");
Log.e(TAG, "onResponse: "+id+"="+firstName+"-"+lastName+"-"+pictureUrl );
String username=firstName+" "+lastName;
insertLinkedinAccount(id,username,pictureUrl,accessToken,expires);
editor.clear();
editor.commit();
} catch (JSONException e) {
e.printStackTrace();
}
//Log.e(TAG, "onApiSuccess:profileData- "+firstName+"-"+lastName+"-"+profileId);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e(TAG, "onErrorResponse: "+error );
}
});
// Add the request to the RequestQueue.
queue.add(stringRequest);
}
