## App Tracking

Start in com.linecorp.linesdk.auth.internal.LineAuthenticationActivity, especially onNewIntent at line 119, and review how LineAuthenticationStatus is restored when activities are recreated. Reproduce with Android developer options enabled for “do not keep activities” on the reported Android 10 environment. Done means the login flow no longer crashes with a null status in this lifecycle scenario.
