Android facebook 4.0.0 分享对话框不分享内容
Android facebook 4.0.0 share dialog does not share the content
几个小时以来，我一直在尝试通过 facebook 4.0.0 sdk 在我的 android 应用程序中分享内容。我完全按照 facebook share document 但没有得到结果。按共享按钮时共享对话框打开，但其中没有内容。如果我单击“确定”，它只会共享一个空字符串。请告诉我解决此问题的方法。

顺便说一句，当我从 phone 中删除 Facebook 原生应用程序时，我可以与 facebook 的 webview 共享。

您需要使用您所在的片段（this）创建 ShareDialog，而不是 activity。 onActivityResult 返回到 activity，因为它被写入，所以它不会进入回调管理器。
这是我在片段中使用的 onClick()，我可以 post 在 FB
上使用它
@Override
public void onClick(View view) {
Profile profile = Profile.getCurrentProfile();
AccessToken accessToken = AccessToken.getCurrentAccessToken();
if (profile != null && accessToken != null) {
if (accessToken.getPermissions().contains("publish_actions")) {
ShareLinkContent shareContent = new ShareLinkContent.Builder()
.setContentTitle(title).setContentDescription(desc)
.setContentUrl(Uri.parse(url))
.build();
ShareDialog shareDialog = new ShareDialog(getActivity());
shareDialog.registerCallback(mCallbackManager, new FacebookCallback<Sharer.Result>() {
@Override
public void onSuccess(Sharer.Result result) {
Toast.makeText(getActivity(), "Share Success", Toast.LENGTH_SHORT).show();
}
@Override
public void onCancel() {
Toast.makeText(getActivity(), "Share Cancelled", Toast.LENGTH_SHORT).show();
}
@Override
public void onError(FacebookException exception) {
Toast.makeText(getActivity(), exception.getMessage(), Toast.LENGTH_LONG).show();
Log.e(TAG, "Share: " + exception.getMessage());
exception.printStackTrace();
}
});
if (ShareDialog.canShow(ShareLinkContent.class)) {
shareDialog.show(shareContent);
}
} else {
List<String> permissions = Arrays.asList("publish_actions");
LoginManager.getInstance().logInWithPublishPermissions(this, permissions);
}
}
}
您的代码在 onError() 方法中出现异常？消息是 "Not found app name"。
如果正确，您需要在清单中添加代码：
<meta-data
android:name="com.facebook.sdk.ApplicationName"
android:value="@string/facebook_app_name" />
您需要在 Facebook 开发网站上的 string.xml 中编辑 app_name 相同的应用程序名称。

我不确定这是否是你的问题，但我在 Facebook 上的分享对话框总是空的。为了解决这个问题，我只是更改了 .setContentUrl。如果您将 link 放入 google 播放或应用程序商店，它只会清空对话框，因此您应该将其更改为任何不同的 link.
几个小时以来，我一直在尝试通过 facebook 4.0.0 sdk 在我的 android 应用程序中分享内容。我完全按照 facebook share document 但没有得到结果。按共享按钮时共享对话框打开，但其中没有内容。如果我单击“确定”，它只会共享一个空字符串。请告诉我解决此问题的方法。
