LINE SDK for Android lets you integrate LINE into your Android app to create a more engaging experience for your users.

Overview

The LINE SDK for Android provides a modern way of implementing LINE APIs. The features included in this SDK will help you develop an Android app with engaging and personalized user experience.

Features

The LINE SDK for Android provides the following features.

User authentication

This feature allows users to log in to your service with their LINE accounts. With the help of the LINE SDK for Android, it has never been easier to integrate LINE Login into your app. Your users will automatically log in to your app without entering their LINE credentials if they are already logged in to LINE on their Android devices. This offers a great way for users to get started with your app without having to go through a registration process.

Utilizing user data with OpenID support

Once the user is authorized, you can get the user’s LINE profile. You can utilize the user's information registered in LINE without building your user system.

The LINE SDK supports the OpenID Connect 1.0 specification. You can get ID tokens that contain the user’s LINE profile when you retrieve the access token.

Setup

Pre-request

Create your own LINE Channel and follow the instructions here to link your app to your channel.

Gradle

Setup current line-sdk version

linesdk_version = '5.6.2'

Add mavenCentral to your repositories if it's not added yet.

repositories {
    ...
	mavenCentral()
}

Import line-sdk dependency

dependencies {
    implementation 'com.linecorp.linesdk:linesdk:$linesdk_version'
    ...
}

Quickstart

A pre-defined LINE login button is provided. You can add it to the user interface of your app to provide your users with a quick way to log in as below

Add login buton to layout xml

<com.linecorp.linesdk.widget.LoginButton
    android:id="@+id/line_login_btn"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

Use it in codes

LoginButton loginButton = rootView.findViewById(R.id.line_login_btn);

// if the button is inside a Fragment, this function should be called.
loginButton.setFragment(this); 

// replace the string to your own channel id.
loginButton.setChannelId("the channel id you created");

// configure whether login process should be done by LINE App, or by WebView.
loginButton.enableLineAppAuthentication(true);

// set up required scopes. 
loginButton.setAuthenticationParams(new LineAuthenticationParams.Builder()
        .scopes(Arrays.asList(Scope.PROFILE))
        .build()
);

// A delegate for delegating the login result to the internal login handler. 
private LoginDelegate loginDelegate = LoginDelegate.Factory.create();
loginButton.setLoginDelegate(loginDelegate);

loginButton.addLoginListener(new LoginListener() {
    @Override
    public void onLoginSuccess(@NonNull LineLoginResult result) {
        Toast.makeText(getContext(), "Login success", Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onLoginFailure(@Nullable LineLoginResult result) {
        Toast.makeText(getContext(), "Login failure", Toast.LENGTH_SHORT).show();
    }
});
