I know that this question has been asked, but there is only one answer pretty much or is not even answered.
I dont know if it's my lack of understanding or lack of Facebook documentation, but so far i have this code to retrieve user email.
callbackManager = CallbackManager.Factory.create();
mFbLoginManager.registerCallback(
callbackManager,
new FacebookCallback < LoginResult > () {
@Override
public void onSuccess(final LoginResult loginResult) {
// Handle success
Log.i(TAG, "callBack Login Result: LoginManager success - " + loginResult.toString());
GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject userObject, GraphResponse response) {
if (response.getError() == null) {
try {
AccessToken token = AccessToken.getCurrentAccessToken();
Log.e(TAG, token.getToken());
Log.e(TAG, userObject.toString());
email = userObject.getString("email");
} catch (JSONException ex) {
Log.e(TAG, "Not such permissions for email!");
ex.printStackTrace();
}
Log.d(TAG, "Email fetched: " + email);
}else{
Log.e(TAG, "Something went wrong with fetching email with GraphRequest");
}
}
}).executeAsync();
}
The JSON string returns only the name and the id, therefore my email variable is empty.
The part i am troubled with is that when i test it on Graph Explorer or with that link, i get the email.
I have se permissions also on the developers site dashboard and also in my code(that's inside onClick() when user press the facebook login button):
mFbLoginManager.logInWithReadPermissions(LoginActivity.this, Arrays.asList("user_photos", "email", "public_profile")
So i am not sure what is the problem in my code. The login button is custom and not the facebook LoginButton, i dont know if that matters.
Every help is welcome
Add below depandancy in Gradle
implementation 'com.facebook.android:facebook-android-sdk:4.11.0'
FacebookSdk.sdkInitialize(this);
callbackManager =CallbackManager.Factory.create();
// -----start putting in oncreate-----------------------
LoginManager.getInstance().logInWithReadPermissions(UserActivity.this, Arrays.asList("public_profile", "user_friends","email"));
facebookTime();
//----onclicklisterner ---------------/
callbackManager.onActivityResult(requestCode,resultCode,data);
//---onactivityresult-------------/
public void facebookTime() {
LoginManager.getInstance().registerCallback(callbackManager,
new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
System.out.println("Success");
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject object, GraphResponse response) {
// Util.showCenteredToast(getActivity(), "object" + object);
// Util.showCenteredToast(getActivity(), "GraphResponse" + response);
try {
strEmail = object.getString("email");
strUserName = object.getString("name");
String id = object.getString("id");
// write your code here
//asyncTask.iSocialMediaResponse = LoginFragment.this;
asyncTask.execute();
} catch (JSONException e) {
e.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "email,name");
//parameters.putString("fields", "user_friends");
request.setParameters(parameters);
//Log.e(" About to Graph Call", " ");
request.executeAsync();
}
@Override
public void onCancel() {
// App code
Util.showCenteredToast(UserActivity.this, "oncancel");
}
@Override
public void onError(FacebookException exception) {
// App code
Util.showCenteredToast(UserActivity.this, "exception" + exception);
}
});
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
callbackManager.onActivityResult(requestCode, resultCode, data);
