Trying to start new activity on certain input of number

I am trying to build an android app for my project in which if i input a certain number in TextView a new activity starts.
I have tried using Intent function and using getText from editText. I dont really understand whats the issue here.
I am new to android studio and also to programming, so i do not have much experience regarding it.

EDIT 1:
I changed my code to this but now i am facing another problem. On input of certain number the new activity starts but on switching to landscape mode the app crashes and none of the operator buttons like +,-,=,*,/ buttons are working.
The app is a basic calculator actually with a different layout in landscape mode and a certain number opens a new activity

UPDATE: I have found the ay to make it work i was making a mistake to take input as float instead of string. changing that has solved my problem thank you for helping me.

You are currently only checking the value once the activity is created, at which point the EditText is empty.
You need to check the value each time the Text gets changed, so take a look at this and put your current code to start the activity into the afterTextChanged method

WhatsApp is not instant check. It's is more like:
Screen off, check 10x after 30s, next 10x after 1m, next 3x after 5m and so on. and start again if the screen turns off again. WhatsApp is checkin in the background also when you close the app. They are using a service.

cannot find symbol method onActivityResult(int,int,Intent)

Im following the tutorial of In-app Billing from the following link:
Android Studio Google Play In-app Billing Tutorial.
Im implementing this logic in a Contact Adapter class which extends Base Adapter. In tutorial it is implemented in a class which extends Activity.
Error comes on onActivityResult(). I read several questions on this and I understand this method should be written in class which extends Activity but in my case the scenario is different.
Is there any way to solve this without writing onActivityResult method in MainActivity class.. and if not what should I do?
