Android LoginActivity, Facebook CallbackManager with Graph API: executeAndWait () method not working
I am new to android and I am creating an application that requires login. The google + and basic email accounts worked so far, but I'm having trouble logging into Facebook. Most of the code I have is sourced from the developer documentation on Facebook and I have tried to use the problem in different ways without any success.
This is my onCreate method where I set up the callbackManager and loginButton. LoginButton registers callbacks. If it is successful, it will start requesting the schedule. However, the method executeAndWait()
never works.
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getApplicationContext());
setContentView(R.layout.activity_login);
mFacebookCallbackManager = CallbackManager.Factory.create();
// Set up facebook login button
LoginButton facebookLoginButton = (LoginButton) findViewById(R.id.facebook_sign_in_button);
facebookLoginButton.setReadPermissions("public_profile", "email");
facebookLoginButton.registerCallback(mFacebookCallbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
Log.e("callback", "success");
new GraphRequest(AccessToken.getCurrentAccessToken(), "/me", null, HttpMethod.GET, new GraphRequest.Callback() {
public void onCompleted(GraphResponse response) {
/* handle the result */
try {
getFacebookUserData(response.getJSONObject());
} catch (JSONException e) {
Log.e("graph request", "json exception");
e.printStackTrace();
}
}
}
).executeAndWait(); //<<<<----- problem is here!!! :(
Log.e("graph request", "executed");
uploadUserToServer();
startLaunchActivity();
}
@Override
public void onCancel() { }
@Override
public void onError(FacebookException exception) {
Log.e("callback", "error");
exception.printStackTrace();}
});
}
This is my onActivityResult () method for callbackManager.
@Override
protected void onActivityResult(final int requestCode, final int resultCode, final Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Log.d(TAG, "onActivityResult:" + requestCode + ":" + resultCode + ":" + data);
mFacebookCallbackManager.onActivityResult(requestCode, resultCode, data);
}
There are other methods in my code that I did not show, but they do other things that are not relevant. This code also does not contain the google + sign which adds a layer of complexity with it onConnectedMethod()
. All I want is GraphRequest execution!
here is the log

Use this code to login to facebook. This works for me.
callbackManager = CallbackManager.Factory.create();
loginButton = (LoginButton) findViewById(R.id.login_button);
List < String > permissionNeeds = Arrays.asList("user_photos", "email",
"user_birthday", "public_profile", "AccessToken");
loginButton.registerCallback(callbackManager,
new FacebookCallback < LoginResult > () {@Override
public void onSuccess(LoginResult loginResult) {
System.out.println("onSuccess");
String accessToken = loginResult.getAccessToken()
.getToken();
Log.i("accessToken", accessToken);
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {@Override
public void onCompleted(JSONObject object,
GraphResponse response) {
Log.i("LoginActivity",
response.toString());
try {
String id = object.getString("id");
try {
URL profile_pic = new URL(
"http://graph.facebook.com/" + id + "/picture?type=large");
Log.i("profile_pic",
profile_pic + "");
} catch (MalformedURLException e) {
e.printStackTrace();
}
String name = object.getString("name");
String email = object.getString("email");
String gender = object.getString("gender");
String birthday = object.getString("birthday");
} catch (JSONException e) {
e.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields",
"id,name,email,gender, birthday");
request.setParameters(parameters);
request.executeAsync();
}
@Override
public void onCancel() {
System.out.println("onCancel");
}
@Override
public void onError(FacebookException exception) {
System.out.println("onError");
Log.v("LoginActivity", exception.getCause().toString());
}
});
@Override protected void onActivityResult(int requestCode, int responseCode, Intent data) { super.onActivityResult(requestCode, responseCode, data); callbackManager.onActivityResult(requestCode, responseCode, data); }
