意图选择器没有显示所有可用选项（三星手机） - 共享内容

Question

这是意图的代码：

<XmlRoot("myvar")> _
Public Class MyVar
    <XmlElement("var")> Public name As String
    <XmlElement("troublecodes")> Public troubleCodes As TroubleCodes
End Class

Public Class TroubleCodes
    <XmlElement("troublecode")> Public troubleCode() As TroubleCode
    <XmlElement("statusbyte")> Public statusByte() As StatusByte
End Class

Public Class TroubleCode
    <XmlElement("one")> Public one As String
    <XmlElement("two")> Public two As String
End Class

Public Class StatusByte
    <XmlElement("three")> Public three As String
    <XmlElement("four")> Public four As String
End Class

在三星手机中，选择器仅显示本机电子邮件应用程序，但不显示已从Play商店安装的应用程序。我还需要添加其他东西吗？
