我得到的错误认证错误215

继承我的代码

我只需要了解oauth

    TwitterTrends objs=gson.fromJson(sb.toString(), TwitterTrends.class);

    Log.e("MY INFO", ""+objs.getTrends().size());
    for(TwitterTrend tr : objs.getTrends()){
        Log.d("TRENDS NAME", tr.getName());
    }

}
}

ive twiiter trend class和twitter trend class

不要担心gson部分

您不做的是让用户登录他的Twitter帐户。确保用户首先登录。登录 - 代码将验证签名，然后才会删除您的错误身份验证错误。

我们可以使用app only auth来获取android中的twitter趋势
