Dear team,

Now I am developing the Ionic based application.

I had developed application for my Android, with the following Ionic configuration,

@Ionic\App script : 3.1.10
Cordova Platforms : Android 6.3.0
Ionic Framework : Ionic Angular 3.9.2
Ionic CLI Version : 3.20.0

In this I have faced some difficulties in the Ionic based application.

I need the answers for following questions.

  1. When I change the Tab , the next page is loaded normally.

    but When I programmatically get the page name , the result page instance is the previous one.

    how could is this possible ?

    I don’t know why it is happened ?

    kindly Advice me ? Am I doing any wrong way ?
