Java 向图像添加元数据以便在android上共享

我正在尝试向android应用程序中的图像添加元数据。 应用程序从库中接收图像，并可以使用“共享”按钮成功转发图像。然而，我正在努力做的是向图像添加元数据。我只需要添加一些简单的数据（主要是描述）

这允许我发送图像，但元数据丢失，标题重置为时间戳。 我尝试使用不同的URI

  Uri i = getApplicationContext().getContentResolver().insert(Images.Media.INTERNAL_CONTENT_URI, values);

但这会导致应用程序崩溃（下面是logcat）

我环顾了很多地方，但没有找到任何有效的方法

非常感谢你的帮助

更新：备用URI的Logcat错误

post logcat错误消息…MainActivity.java:128上有什么？这是备用URI:URI i=getApplicationContext（）.getContentResolver（）.insert（Images.Media.INTERNAL\u CONTENT\u URI，值）；
