LinkedIn Android SDK出现访问令牌问题：未设置访问令牌。授权时

Question

我想使用LinkedIn android SDK分享信息到LinkedIn。以前，它工作正常。但是从过去几天开始，我突然收到“未设置访问令牌” 的异常。

我用于登录的代码：

public void login(final OnAuthorization onAuthorization) {

    if (context instanceof Activity) {

        Scope scope = Scope.build(Scope.R_BASICPROFILE, Scope.R_EMAILADDRESS, Scope.W_SHARE, Scope.RW_COMPANY_ADMIN);
        LISessionManager.getInstance(context).init((Activity) context, scope//pass the build scope here
                , new AuthListener() {
                    @Override
                    public void onAuthSuccess() {
                        onAuthorization.onAuthSuccess();
                    }

                    @Override
                    public void onAuthError(LIAuthError error) {
                        // Handle authentication errors
                        onAuthorization.onAuthFailure(error);
                        Log.e("linkedin error ", "Auth Error :" + error.toString());

                    }
                }, true);//if TRUE then it will show dialog if
        // any device has no LinkedIn app installed to download app else won't show anything
    }
}

此处OnAuthorization是通知LinkedIn成功与失败的界面。

public interface OnAuthorization {
    void onAuthSuccess();

    void onAuthFailure(LIAuthError liAuthError);
}

成功通过LinkedIn身份验证（登录）。共享完成。

public void share(BlogInfo blogInfo, final OnSharingComplete onSharingComplete) {

    String url = "https://api.linkedin.com/v1/people/~/shares";

    Visibility visibility = new Visibility(Visibility.CODE_ANYONE);
    Content content = new Content(blogInfo.getTitle(), blogInfo.getContent(), blogInfo.getBlogUrl(), blogInfo.getImageUrl());

    LinkedInShareRequestModel linkedInShareRequestModel = new LinkedInShareRequestModel(blogInfo.getDate(), visibility, content);

    Log.e("gson", new Gson().toJson(linkedInShareRequestModel));

    APIHelper apiHelper = APIHelper.getInstance(context);

    apiHelper.postRequest(context, url, new Gson().toJson(linkedInShareRequestModel), new ApiListener() {
        @Override
        public void onApiSuccess(ApiResponse apiResponse) {
            // Success!
            Log.d("", "Share response : " + apiResponse.toString());
            onSharingComplete.onComplete(true, null);
            logout();
        }

        @Override
        public void onApiError(LIApiError liApiError) {
            // Error making POST request!
            Log.e("", "Share error : " + liApiError.getLocalizedMessage());
            onSharingComplete.onComplete(false, liApiError);
        }
    });

}

在这里，BlogInfo是一个如下模型

public class BlogInfo implements Parcelable {

public static final Creator<BlogInfo> CREATOR = new Creator<BlogInfo>() {
    @Override
    public BlogInfo createFromParcel(Parcel in) {
        return new BlogInfo(in);
    }

    @Override
    public BlogInfo[] newArray(int size) {
        return new BlogInfo[size];
    }
};
private int id;
private String title;
private String subTitle;
private String content;
private String date;
private String imageUrl;
private String blogUrl;

public BlogInfo(int id, String title, String subTitle, String content, String date, String imageUrl, String blogUrl) {
    this.id = id;
    this.title = title;
    this.subTitle = subTitle;
    this.content = content;
    this.date = date;
    this.imageUrl = imageUrl;
    this.blogUrl = blogUrl;
}

public BlogInfo(String title, String subTitle, String content, String date, String imageUrl, String blogUrl) {
    this.title = title;
    this.subTitle = subTitle;
    this.content = content;
    this.date = date;
    this.imageUrl = imageUrl;
    this.blogUrl = blogUrl;
}

private BlogInfo(Parcel in) {
    id = in.readInt();
    title = in.readString();
    subTitle = in.readString();
    content = in.readString();
    date = in.readString();
    imageUrl = in.readString();
    blogUrl = in.readString();
}

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public String getTitle() {
    return title;
}

public void setTitle(String title) {
    this.title = title;
}

public String getSubTitle() {
    return subTitle;
}

public void setSubTitle(String subTitle) {
    this.subTitle = subTitle;
}

public String getContent() {
    return content;
}

public void setContent(String content) {
    this.content = content;
}

public String getDate() {
    return date;
}

public void setDate(String date) {
    this.date = date;
}

public String getImageUrl() {
    return imageUrl;
}

public void setImageUrl(String imageUrl) {
    this.imageUrl = imageUrl;
}

public String getBlogUrl() {
    return blogUrl;
}

public void setBlogUrl(String blogUrl) {
    this.blogUrl = blogUrl;
}

@Override
public int describeContents() {
    return 0;
}

@Override
public void writeToParcel(Parcel parcel, int flags) {

    parcel.writeInt(id);
    parcel.writeString(title);
    parcel.writeString(subTitle);
    parcel.writeString(content);
    parcel.writeString(date);
    parcel.writeString(imageUrl);
    parcel.writeString(blogUrl);
}
}

和OnSharingComplete还是一个界面，用于通知共享是成功完成还是失败。

public interface OnSharingComplete {
    void onComplete(boolean isSuccessful,Exception exception);
}

有人可以帮我解决这个错误吗？？
