I am trying to integrate Facebook into my Android app. Using the Facebook Login Button, I tried to login in. When I first install the app, it works fine and login successfully. When I logged out using that button, and then try to login again, it shows the permission dialogue but SessionState return state is closed. Any Suggestions?
Here is my Code
public class LoginActivity extends FragmentActivity {
// private Login login;
private boolean isResumed = false;
private BirthDayComp app;
private int Login = 0;
private int LogOut = 1;
private int Count = LogOut + 1;
private boolean loged = false;
private Fragment[] fragments = new Fragment[Count];
private UiLifecycleHelper uiHelper;
private Session.StatusCallback callback = new Session.StatusCallback() {
@Override
public void call(Session session, SessionState state, Exception exception) {
onSessionStateChange(session, state, exception);
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.login_fragment);
uiHelper = new UiLifecycleHelper(this, callback);
uiHelper.onCreate(savedInstanceState);
FragmentManager fm = getSupportFragmentManager();
fragments[Login] = fm.findFragmentById(R.id.loginfb);
fragments[LogOut] = fm.findFragmentById(R.id.logoutfb);
FragmentTransaction transaction = fm.beginTransaction();
transaction.commit();
/*if (savedInstanceState == null) {
login = new Login();
getSupportFragmentManager()
.beginTransaction()
.add(android.R.id.content, login)
.commit();
} else {
login = (Login) getSupportFragmentManager()
.findFragmentById(android.R.id.content);
}*/
}
@Override
public void onResume() {
super.onResume();
uiHelper.onResume();
isResumed = true;
}
@Override
public void onPause() {
super.onPause();
uiHelper.onPause();
/* Session session = Session.getActiveSession();
session.removeCallback(callback);*/
isResumed = false;
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// uiHelper.onActivityResult(requestCode, resultCode, data);
// super.onActivityResult(requestCode, resultCode, data);
Session session = Session.getActiveSession();
int sanitizedRequestCode = requestCode % 0x10000;
session.onActivityResult(this, sanitizedRequestCode, resultCode, data);
}
@Override
public void onDestroy() {
super.onDestroy();
uiHelper.onDestroy();
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
uiHelper.onSaveInstanceState(outState);
}
@Override
protected void onResumeFragments() {
super.onResumeFragments();
Session session = Session.getActiveSession();
if (session != null && session.isOpened()) {
// if the session is already open, try to show the selection fragment
/*if(app.getFb()!=true){
app.setFb(true);
}*/
showFragment(Login, false);
} else {
// otherwise present the splash screen and ask the user to login.
//app.setFb(false);
showFragment(Login, false);
}
}
private void onSessionStateChange(Session session, SessionState state, Exception exception) {
if (isResumed) {
FragmentManager manager = getSupportFragmentManager();
int backStackSize = manager.getBackStackEntryCount();
for (int i = 0; i < backStackSize; i++) {
manager.popBackStack();
}
// check for the OPENED state instead of session.isOpened() since for the
// OPENED_TOKEN_UPDATED state, the selection fragment should already be showing.
session = Session.getActiveSession();
state = session.getState();
if (state.equals(SessionState.OPENED)) {
this.loged = true;
showFragment(Login, false);
} else if (state.isClosed()) {
this.loged = false;
System.gc();
//session.closeAndClearTokenInformation();
// showFragment(Login, false);
}
}
}
private void showFragment(int fragmentIndex, boolean addToBackStack) {
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction transaction = fm.beginTransaction();
for (int i = 0; i < fragments.length; i++) {
if (i == fragmentIndex) {
transaction.show(fragments[i]);
} else {
transaction.hide(fragments[i]);
}
}
if (addToBackStack) {
transaction.addToBackStack(null);
}
transaction.commit();
}
}
