Saving Data on Android

Firebase analy/cs
To build a successful app, you need to clearly understand how your users behave and 
how they use your app. This is why analytics are so important.
There are many analytics categories that your app can use. This includes, in-app 
behavior analytics, which measures who your users are and what they are doing; 
attribution analytics, which you can use to measure the effectiveness of your 
advertising and other growth campaigns; push notifications analytics, crash 
reporting analytics and more.
Without Firebase, you may need to use multiple analytics libraries and tools to 
collect and save your analytics data. This becomes problematic when you need to 
share analytics data among those tools. Analytics for Firebase, however, is built to 
provide all of the data mobile app developers need in one place. Analytics integrates 
across Firebase features and provides you with two key capabilities: unlimited 
reporting for up to 500 distinct events and audience segmentation. With audience 
segmentation, you can create a custom audience that you target with new features or 
notification messages, for example. You can choose your custom audience base using 
parameters like device data or user properties.
Once you integrate your app with Firebase, analytics comes standard out-of-the-box.
Developing
Firebase offers many products that help you develop your app. Products that you’ll 
use in this section of the book are Authentication, Realtime Database, Cloud 
Firestore and Cloud Storage. Let’s take a look at each one.

Most apps need a way to identify a user so they can customize their experience and 
keep user data secure, while making authentication easy for both end users and 
developers.
Firebase supports many different ways for your users to authenticate. 
Firebase Auth
 
has built-in functionality for third-party providers such as Facebook, Twitter, Github 
or Google. If you want to authenticate users via an email address, you can do that, 
too.

You can present login functionality to the users in two different ways: using your 
own interface or taking advantage of Firebase’s open source UI, which is also 
customizable. When the user authenticates, information about that user is returned 
to the device via a callback. You can then use that information to customize the 
experience for the specific user.
Firebase also manages user sessions, which means that users will remain logged in 
after the app restarts.
