我在实施Facebook共享信息时遇到了这样一个奇怪的错误。 我在Facebook教程Facebook tutorial - share info
中描述了所有阶段但是当我尝试创建 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();
}
我抓住了 FacebookException ！

正如我从日志中可以理解的那样，主要的麻烦是 Session.getActiveSession（）的结果不应该为空并且应该打开但是因为我看到会话具有状态只创建了！ 但我做了Facebook教程所说的所有阶段！求救！
答案 0 :(得分：7)
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();
}
}
};

除了上面接受的答案之外，如果这是第一次用户体验流程，用户将需要登录才能创建会话。为此，您需要将LoginActivity添加到AndroidManifest.xml -
<activity
android:name="com.facebook.LoginActivity"
android:label="@string/title_activity_facebook_login" >
</activity>
