@moemen according to you the data is storing successfully and you need to call that data and compare the tag and value so you can do like this
Call tag list (it will call all the tags in the form of a list)
When got tag list then
if (is in list, thing emailtextbook.text, list get value) {
Call get value from firebase tag = emailtextbook.text
}
When got value {
if (password.text == get value){
Go to other screen
}
}
I have written it in simple language to make it understandable else I would have written it in java code
I'll provide you the example blocks soon till then try this method and later you will also get the blocks
Hope this might help you if not message me personally I'll help you surely
Off Topic
Actually I have made a fully functioning chat app and there is was using this kind of login system.
That's why I know this all
You have the right to look after your users privacy....
Firebase does not present an authenticated user's password anywhere, you would have to get it from the app
Please stop making a new topic every time you have a question when it relates to your existing topic. Just continue the conversation in the existing topic.
You are testing a demo app for single auth / multiuser login on Firebase.
You have signed up as a user
Now enter some data, and see how it appears in the firebase console
You should also be able to see the users section
Restart the app and signup as a different user (there is no verification so it doesn't have to be a real email address), then check the users section again in the firebase console. As you wanted (your rights) you can see all the sign up / login details for each user....
You may need to create a new firebase project and select the US server (not the EU server). I do not know why this is a problem but switching to the US server usually fixes the problem.
Also, or alternatively, once project is created, and you want to use Authentication features, select Authentication and enable email/password (for this project)
