我在实现 Facebook 共享信息时遇到了这样一个奇怪的错误。 我按照 Facebook 教程中的描述制作了所有阶段 Facebook tutorial - share info
但是当我尝试创建 WebDialog.feedDialog 的示例时
private void publishFeedDialog() {
Bundle params = new Bundle();
params.putString("name", getString(R.string.name_fb));
params.putString("description", getString(R.string.description_fb));
params.putString("link", getString(R.string.share_link_fb));
params.putString("picture", getString(R.string.pictute_url_fb));
Session session = Session.getActiveSession();
Log.i(TAG, "session = " + session + " isOpen = " + session.isOpened() + " isClosed = " + session.isClosed());
WebDialog feedDialog = (new WebDialog.FeedDialogBuilder(this, Session.getActiveSession(), params))
.setOnCompleteListener(new OnCompleteListener() {
@Override
public void onComplete(Bundle values, FacebookException error) {
if (error == null) {
// When the story is posted, echo the success and the post Id.
final String postId = values.getString("post_id");
if (postId != null) {
Toast.makeText(MainActivity.this, "Posted story, id: " + postId,
Toast.LENGTH_SHORT).show();
} else {
// User clicked the Cancel button
Toast.makeText(MainActivity.this, "Publish cancelled",
Toast.LENGTH_SHORT).show();
}
} else if (error instanceof FacebookOperationCanceledException) {
// User clicked the "x" button
Toast.makeText(MainActivity.this, "Publish cancelled", Toast.LENGTH_SHORT).show();
} else {
// Generic, ex: network error
Toast.makeText(MainActivity.this, "Error posting story", Toast.LENGTH_SHORT).show();
}
}
}).build();
feedDialog.show();
}我捕获了 FacebookException!

09-22 19:34:52.475: I/GAV3(12202): Thread[GAThread,5,main]: No campaign data found.正如我从日志中了解到的，主要问题是 Session.getActiveSession() 的结果不应该为 null 并且应该打开，但正如我所看到的 session 有状态仅创建! 但我按照 Facebook 教程所说的完成了所有阶段!请帮忙!
最佳答案
经过调查我解决了我的问题:
1) 在创建feedDialog之前我应该检查Active Session是否打开，如果没有那么我应该直接打开Active Session
if (Session.getActiveSession() == null || !Session.getActiveSession().isOpened()) {
Session.openActiveSession(MainActivity.this, true, callback);
} else {
publishFeedDialog();
}2) 并在 Session.StatusCallback 中调用 publishFeedDialog()
private Session.StatusCallback callback = new Session.StatusCallback() {
@Override
public void call(Session session, SessionState state, Exception exception) {
if (state.isOpened() && isFbShare) {
publishFeedDialog();
}
}
};关于android - Facebook SDK : not "opened" session state while creating WebDialog. FeedDialogBuilder，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/25979281/
