A malicious client can send an arbitrary user ID or malformed information to your server to impersonate a user. As shown in the example above, you can retrieve the access token using the following code.ĭo not trust user IDs, or other information available in the LineProfile object, when sent by a client to your backend server. The login result contains a LineCredential() object which contains the user’s access token. addLoginListener ( new LoginListener ( ) # Get the access token nonce("") // nonce can be used to improve security. setAuthenticationParams ( new LineAuthenticationParams. enableLineAppAuthentication ( true ) // set up required scopes and nonce. toString ( ) ) // configure whether login process should be done by Line App, or inside WebView. line_login_btn ) // if the button is inside a Fragment, this function should be called.
create ( ) LoginButton loginButton = rootView.

The first time the user shares the text, my app gets the text as expected and displays it via Log.d() - see the handleSendText() method in the code below. In this case, I'll use the basic Android web browser to select text and then share it to my app. I am attempting to get data sent from the user via the Share menu.
