我正试着在Facebook上分享一些东西。在guide之后,我设法在您拥有原生应用时完成共享。但是,当我达到这个目的时:
步骤4:使用Feed对话框作为后备。它说为了能够使用回退方法,我需要添加下面的代码
private void publishFeedDialog() {
Bundle params = new Bundle();
params.putString("name", "Facebook SDK for Android");
params.putString("caption", "Build great social apps and get more installs.");
params.putString("description", "The Facebook SDK for Android makes it easier and faster to develop Facebook integrated Android apps.");
params.putString("link", "https://developers.facebook.com/android");
params.putString("picture", "https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png");
WebDialog feedDialog = (
new WebDialog.FeedDialogBuilder(getActivity(),
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(getActivity(),
"Posted story, id: "+postId,
Toast.LENGTH_SHORT).show();
} else {
// User clicked the Cancel button
Toast.makeText(getActivity().getApplicationContext(),
"Publish cancelled",
Toast.LENGTH_SHORT).show();
}
} else if (error instanceof FacebookOperationCanceledException) {
// User clicked the "x" button
Toast.makeText(getActivity().getApplicationContext(),
"Publish cancelled",
Toast.LENGTH_SHORT).show();
} else {
// Generic, ex: network error
Toast.makeText(getActivity().getApplicationContext(),
"Error posting story",
Toast.LENGTH_SHORT).show();
}
}
})
.build();
feedDialog.show();
}
添加此内容后,我在getActivity()
收到错误,我使用MyClass.this
解决此问题。
然后,当我运行应用程序(我在启动时直接运行此方法)时,我的应用程序崩溃,我收到一些错误,例如“尝试使用未打开的会话”
任何人都知道如何在没有安装原生应用的情况下分享内容?
答案 0 :(得分:0)
导致错误的原因是用户尚未通过您的应用登录Facebook。您需要在应用中的某个位置实施登录Facebook。即使用户没有安装本机应用程序,Facebook SDK也将回退到webdialog以请求用户登录。因此,您需要检查会话是否已打开(即用户是否已登录)。 / p>
Session session = Session.getActiveSession();
boolean isSessionOpen = (session != null && session.isOpened());
if(!isSessionOpen) {
Toast.makeText(getApplicationContext(),"Please Login With Facebook First!", Toast.LENGTH_SHORT).show();
return;
}
