I have the below onclick for a facebook login button:
fblogin.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Session session = Session.getActiveSession();
if (session == null) {
Session.openActiveSession(LogIn.this, true,
statusCallback);
} else if (!session.isOpened()) {
session.openForRead(new Session.OpenRequest(
LogIn.this).setCallback(statusCallback)
.setPermissions(permissions)
);
}
}
});
And then have the below logout onclick:
private OnClickListener OnClick_logout = new OnClickListener() {
public void onClick(View v) {
SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
SharedPreferences.Editor editor = settings.edit();
editor.putBoolean("loggedIn", false);
editor.putString("email", "");
editor.putString("password", "");
editor.commit();
db.clearLists();
db.clearProducts();
Intent intent = new Intent(v.getContext(), Splash.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP );
v.getContext().startActivity(intent);
}
};
Currently this does not logout facebook which means when the user goes back to the LogIn activity and trys to click the fblogin button nothing happens.
What would I need to add to my logout onclick to actually log facebook out so that the user can press the fblogin button again and login again.
I have tried adding to the logout button:
Session.getActiveSession().closeAndClearTokenInformation();
However when I then go back to the login screen and click the login button I get:
10-30 10:51:14.776: E/AndroidRuntime(18964): java.lang.UnsupportedOperationException: Session: an attempt was made to open an already opened session.
