JP Notify

JP Notify is an Android app that helps you memorize JLPT kanji passively. Every time you turn off your phone screen, the app shows a flashcard-style notification with a random kanji and its meaning.

How It Works

• The app uses a BroadcastReceiver that listens for the SCREEN_OFF event.
• When the screen is turned off, it randomly selects a kanji from a local SQLite database.
• A notification is shown with the kanji (and reading) as well as the meaning.
• The user can configure which JLPT levels (N1 to N5) are included.

Permissions

Android 13 and above require runtime permission for notifications:

<uses-permission android:name="android.permission.POST_NOTIFICATIONS" />
