尝试调用2个应用程序以从一个应用程序检索数据并粘贴到另一个应用程序

Question

我有一个应用程序，每次我尝试登录时都可以使用。我必须在登录之前将该设备注册为设备。因此，我必须提供我的LASTNAME和USERID并单击REGISTER。完成此过程后，它将激活码发送到我的GMAIL。因此，在这里我必须调用GMAIL APP“问题1”。 NExt我必须输入主题激活码“问题2”的gmail。并从消息“问题3”中获取激活码。

到目前为止，我已经能够调用以我的姓氏，USER ID和REGISTER注册的第一个应用程序。之后，我无法调用第二个应用程序并检索数据。我是新来的鸦片迷，请帮忙enter image description here
