What is the difference between Android 10 and Android 11?

The main differences between Android 10 and Android 11 concern privacy, notification management, dialogues, and multitasking.

Feature	Android 10	Android 11
Location permissions	"Allow all the time", "Allow only while using the app", "Deny"	Added "Allow only this time" (for one-time access).
Data access permissions	Managed through app settings.	Automatic reset of permissions for unused apps. Improved Scoped Storage (restricted access storage area).
Notifications	Grouped by app type, prioritization.	Added "Conversations" category for chat prioritization. Improved notification management in the shade.
Dialogs	Not categorized separately.	Separate "Conversations" section in the notification shade for quick access to chats.
Multitasking	Split-screen mode, gestures.	Improved media management, quick device switching for playback. Enhanced app power management.
Screen recording	Requires third-party apps.	Built-in screen recording feature.
File access	Broader access to the file system.	Stricter file access control via Scoped Storage. Complex access to shared directories without explicit permissions.

Example of using Scoped Storage:

// Example of accessing media files using MediaStore and Scoped Storage
Uri collection = MediaStore.Images.Media.getContentUri(MediaStore.VOLUME_EXTERNAL_PRIMARY);

ContentResolver contentResolver = getContentResolver();

String[] projection = new String[] {
        MediaStore.Images.Media._ID,
        MediaStore.Images.Media.DISPLAY_NAME,
        MediaStore.Images.Media.DURATION,
        MediaStore.Images.Media.SIZE
};

try (Cursor cursor = contentResolver.query(
        collection,
        projection,
        null, // selection
        null, // selectionArgs
        null  // sortOrder
)) {
    // Handling cursor data
}
