问题
Help,
I am trying to make a class that handles facebook login in my application. My problem is it doesnt work on all activity. On that activity it doesnt call the callback. After the login and authorize application webview is dismiss, the callback doesnt fire. the last state that printed in Logcat is OPENING
Here is my code:
public void doLogin() {
if ((Session.getActiveSession() == null || !Session.getActiveSession().isOpened())) {
List<String> permissions = new ArrayList<String>();
permissions.add("email");
// start Facebook Login
openActiveSession(activity, true, new Session.StatusCallback() {
// callback when session changes state
@Override
public void call(Session session, SessionState state,
Exception exception) {
Log.d("Sessionstate", state.toString());
if (session.isOpened()) {
// make request to the /me API
Request.executeMeRequestAsync(session,
new Request.GraphUserCallback() {
@Override
public void onCompleted(GraphUser user,
Response response) {
if (prgCheckFB.isShowing())
prgCheckFB.dismiss();
if (user != null) {
Log.e("facebookid", id);
doSomething(user);
}
}
});
}
}, permissions);
}
}
private static Session openActiveSession(Activity activity,
boolean allowLoginUI, Session.StatusCallback callback,
List<String> permissions) {
Session.OpenRequest openRequest = new Session.OpenRequest(activity)
.setPermissions(permissions).setCallback(callback);
Session session = new Session.Builder(activity).build();
if (SessionState.CREATED_TOKEN_LOADED.equals(session.getState())
|| allowLoginUI) {
Session.setActiveSession(session);
session.openForRead(openRequest);
return session;
}
return null;
}
doSomething is function that will save the user data in a shared preference.
Is there anything wrong? The function works in some activity but not ALL activities.
Thank you
回答1:
maybe you forget to handle the results after login...
check the override method onActivityResult..
because it handle the results back to the MainActivity,
maybe this can help your problem..
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Session.getActiveSession().onActivityResult(this, requestCode,
resultCode, data);
}
Update 1
For newer SDK use:
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
callbackManager.onActivityResult(requestCode,
resultCode, data);
}

Having the attribute android:noHistory="true" set for your callback activity in the AndroidManifest.xml file will also result with the callback methods not firing.
