我尝试使用带有 SDK 3.5 的 Facebook 登录，但我无法让它工作。
登录弹出窗口不显示。
当用户单击我的按钮时，我使用此代码启动登录过程：
private void onClickLogin() {
Session currentSession = Session.getActiveSession();
if (currentSession == null || currentSession.getState().isClosed()) {
Session session = new Session.Builder(RegisterPage.this).build();
Session.setActiveSession(session);
currentSession = session;
}
if (currentSession.isOpened()) {
// Do whatever u want. User has logged in
} else if (!currentSession.isOpened()) {
// Ask for username and password
OpenRequest op = new Session.OpenRequest((Activity) RegisterPage.this);
op.setLoginBehavior(SessionLoginBehavior.SUPPRESS_SSO);
op.setCallback(null);
List<String> permissions = new ArrayList<String>();
permissions.add("publish_stream");
permissions.add("user_likes");
permissions.add("email");
permissions.add("user_birthday");
op.setPermissions(permissions);
Session session = new Session.Builder(RegisterPage.this).build();
Session.setActiveSession(session);
session.openForPublish(op);
}
}
而这个 onActivityResult
@Override
protected void onActivityResult(int requestCode, int resultCode,
Intent data2)
{
if (Session.getActiveSession() != null)
Session.getActiveSession().onActivityResult(this, requestCode,
resultCode, data2);
Session currentSession = Session.getActiveSession();
if (currentSession == null || currentSession.getState().isClosed()) {
Session session = new Session.Builder(this).build();
Session.setActiveSession(session);
currentSession = session;
}
if (currentSession.isOpened()) {
Session.openActiveSession(this, true, new Session.StatusCallback() {
@SuppressWarnings("deprecation")
@Override
public void call(final Session session, SessionState state,
Exception exception) {
if (session.isOpened()) {
Request.executeMeRequestAsync(session,
new Request.GraphUserCallback() {
@Override
public void onCompleted(GraphUser user,
Response response) {
if (user != null) {
facebook_name = user.getName();
facebook_id = user.getId();
email = (String) user.getProperty("email");
Log.i("email", email);
Log.i("facebook_name", facebook_name);
if(isNetworkAvailable())
new GetProfilePicture().execute();
}
}
});
}
}
});
}
}
