I am able to fetch friend list and associated object id but I dont know how to pass these to another activity. When I use intent to pass data, I get an empty result in the next activity. Please can someone help me out.
Here is my code
public class MainFragment extends Fragment {
private CallbackManager callbackManager;
private TextView textView;
private AccessTokenTracker accessTokenTracker;
private ProfileTracker profileTracker;
static ArrayList<String> friendlist = new ArrayList<String>();
public MainFragment() {
}
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getActivity().getApplicationContext());
callbackManager = CallbackManager.Factory.create();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_main, container, false);
}
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
LoginButton loginButton = (LoginButton) view.findViewById(R.id.login_button);
final ProfilePictureView pictureView=(ProfilePictureView) view.findViewById(R.id.picture);;
loginButton.setFragment(this);
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>()
{
@Override
public void onSuccess(LoginResult loginResult) {
// AccessToken accessToken = loginResult.getAccessToken();
Toast.makeText(getActivity().getApplicationContext(),"Login Success", Toast.LENGTH_LONG).show();
LoginManager.getInstance().logInWithReadPermissions(getActivity(), Arrays.asList("user_friends","user_photos","email"));
GraphRequest request = GraphRequest.newMeRequest(
AccessToken.getCurrentAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(
JSONObject object,
GraphResponse response) {
// Application code
String name = object.optString("name");
String id = object.optString("id");
String email = object.optString("email");
Log.d("Name",name);
Log.d("ID",id);
Log.d("email",email);
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email");
request.setParameters(parameters);
request.executeAsync();
GraphRequestBatch batch = new GraphRequestBatch(
GraphRequest.newMyFriendsRequest(
AccessToken.getCurrentAccessToken(),
new GraphRequest.GraphJSONArrayCallback() {
@Override
public void onCompleted(
JSONArray jsonArray,
GraphResponse response) {
JSONObject object=response.getJSONObject();
try {
JSONArray listFriends = object.getJSONArray("data");
//get the entire friendlist
for(int i=0;i<listFriends.length();i++)
{
JSONObject firstFriend=listFriends.getJSONObject(i);
friendlist.add(firstFriend.optString("name"));
Log.d("listOfFriends", String.valueOf(friendlist));
}
// String friendName=firstFriend.optString("name");
// Log.d("friendname",friendName);
//String friendid = firstFriend.optString("id");
Log.d("listFriends", listFriends.length() + "");
} catch (JSONException e) {
e.printStackTrace();
}
}
}),
GraphRequest.newMyFriendsRequest(
AccessToken.getCurrentAccessToken(),
new GraphRequest.GraphJSONArrayCallback() {
@Override
public void onCompleted(
JSONArray jsonArray,
GraphResponse response) {
// Application code for users friends
}
})
);
batch.addCallback(new GraphRequestBatch.Callback() {
@Override
public void onBatchCompleted(GraphRequestBatch graphRequests) {
// Application code for when the batch finishes
}
});
batch.executeAsync();
}
@Override
public void onCancel() {
Toast.makeText(getActivity().getApplicationContext(),"Login Cancel", Toast.LENGTH_LONG).show();
}
@Override
public void onError(FacebookException e) {
Toast.makeText(getActivity().getApplicationContext(),"Login Error", Toast.LENGTH_LONG).show();
}
});
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
callbackManager.onActivityResult(requestCode, resultCode, data);
Intent secondActivityIntent = new Intent(MainFragment.this.getActivity(), BackCamera.class);
secondActivityIntent.putExtra("friendlist", friendlist);
Log.d("friendlistnew", String.valueOf(friendlist));
startActivity(secondActivityIntent);
}
@Override
public void onStop() {
super.onStop();
}
@Override
public void onResume() {
super.onResume();
Profile profile = Profile.getCurrentProfile();
}
}
Thanks in advance!
