Thank you for using BOOK☆WALKER.
Currently, we offer BOOK☆WALKER app for Android and iOS, as well as the Browser Viewer as reading tools for our customers.
However, there has been an update of Android OS (Android 9 "Pie") on August 6th PT (Pacific Time), and since BOOK☆WALKER app for Android (version 4.2.2) does not correspond to this OS, the app may not operate properly when the OS is updated.
In such case, please update the Android app to the latest version from Google Play.
