Answer 1

If you want to read WhatsApp data,

Android 11: [EDIT]

String path=  Build.VERSION.SDK_INT<=30  ? "WhatsApp/Media/Wallpaper":"Android/media/com.whatsapp/WhatsApp/Media/Wallpaper";

Add Read Permission:

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

Add Exact path:

String path=  "Android/media/com.whatsapp/WhatsApp/Media/WhatsApp <####>";

And finally read all data

private void loadData(String path) {
    File folder = new File(Environment.getExternalStorageDirectory().toString() + path);
    folder.mkdirs();


    File[] allFiles = folder.listFiles(new FilenameFilter() {
        public boolean accept(File dir, String name) {
            return (name.endsWith(".jpg") || name.endsWith(".jpeg") || name.endsWith(".png"));
        }
    });
    Log.e("Datas" , allFiles.toString());
}

Other paths:

        String pathWallPaper=  "Android/media/com.whatsapp/WhatsApp/Media/Wallpaper";
        String pathGif=  "Android/media/com.whatsapp/WhatsApp/Media/WhatsApp Animated Gifs";
        String pathAudio=  "Android/media/com.whatsapp/WhatsApp/Media/WhatsApp Audio";
        String pathDocs=  "Android/media/com.whatsapp/WhatsApp/Media/WhatsApp Documents";
        String pathImage=  "Android/media/com.whatsapp/WhatsApp/Media/WhatsApp Images";
        String pathStickers=  "Android/media/com.whatsapp/WhatsApp/Media/WhatsApp Stickers";
        String pathVideo=  "Android/media/com.whatsapp/WhatsApp/Media/WhatsApp Video";
