Android 更新sdk 24后刷新json视图不起作用
切换到sdk24后，我遇到了一个问题。 阅读json php应用程序，但不再更新。你必须给她闭包，迫使她重读。 以前我经常刷新和更新listfragment perfect。不是现在。 我给我添加的新信息被添加到数据库中，或者你可以删除，但应用程序不更新 代码json阅读器+插入+删除+刷新：Android 更新sdk 24后刷新json视图不起作用,android,android-fragments,android-json,Android,Android Fragments,Android Json,切换到sdk24后，我遇到了一个问题。 阅读json php应用程序，但不再更新。你必须给她闭包，迫使她重读。 以前我经常刷新和更新listfragment perfect。不是现在。 我给我添加的新信息被添加到数据库中，或者你可以删除，但应用程序不更新 代码json阅读器+插入+删除+刷新： public class playlist_torrent extends ListFragment { Main2Activity activity= (Main2Activity) g

如果您留出几分钟的时间间隔并刷新它，它就会运行。但只有一次。就好像连接保持打开且不再响应一样。修复了来自apache2的更改的ngix的此问题，现在工作正常。修复了来自apache2的更改的ngix的此问题，现在工作正常
