Session Management in Android with Example
Session Management is one of the most important features that are to be used in the Android App when you are integrating the login feature in Android. In your android app if you are using a feature of Login then you should have to save the state if the user has signed the first time. Then when the user closes his app and reopens it then he should redirect to our Home screen, rather than opening a login screen. So in this article, we will implement Session Management functionality in our Android app. For implementing this functionality we are creating a simple login form and a home screen. In our login form, the user has to enter his credentials and login into the app. After login, the user’s credentials will be saved inside the app, and whenever he reopens the app the user will be redirected to the home screen. For session management inside our app, we will be using Shared Preferences to store users’ credentials. Now we will move towards the implementation part.
We will be creating a simple Login app as mentioned above for storing user session. A sample GIF is given below in which we will get to see what we will be building in our app. Note that we will be implementing this project using Java language.
Step by Step Implementation
Step 1: Create a New Project
To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. Note that select Java as the programming language.
Step 2: Add the below strings in your strings.xml file
Navigate to the app > res > values > strings.xml and add the below strings to it.
Step 3: Working with the activity_main.xml file
Go to the activity_main.xml file and refer to the following code. Below is the code for the activity_main.xml file.
Step 4: Create a new Activity for Home Screen
Navigate to the app > java > your app’s package name > Right-Click on your package name and New > Activity > Empty Activity and make sure to keep your language as Java. Name the activity as HomeActivity.
Step 5: Working with the MainActivity.java file
Go to the MainActivity.java file and refer to the following code. Below is the code for the MainActivity.java file. Comments are added inside the code to understand the code in more detail.
Step 6: Now we will work on our Home Screen
Inside our home screen, we will be displaying users’ email address and a logout button so that users can Logout of the app. For Home Screen, we have created an activity named as HomeActivity. Navigate to the app > res > layout > activity_home.xml and open it and add the below code to it.
Now we will move towards the java file of our HomeActivity. Navigate to the app > java > your app’s package name and open the HomeActivity.java file. Add below code inside that file.
