Because your gallery DB isn't updated.

You can run media scanner manually

sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://" + Environment.getExternalStorageDirectory())));

or Use

MediaStore.Images.Media.insertImage();

You can also insert gallery(media) DB by hand.

private Uri insertMediaStore(String dirPath, String filename, byte[] jpegByteArray) {
    String filePath = dirPath + "/" + filename;

    try {
        ContentValues values = new ContentValues();
        values.put(Images.Media.DATE_TAKEN, new Date().getTime());
        values.put(Images.Media.ORIENTATION, "0");

        String title = filename.replace(".jpg", "");

        values.put(Images.Media.TITLE, title);
        values.put(Images.Media.DISPLAY_NAME, filename);
        values.put(Images.Media.MIME_TYPE, "image/jpeg");
        values.put(Images.Media.SIZE, jpegByteArray.length);
        values.put("_data", filePath);

        Uri uri = getContentResolver().insert(Images.Media.EXTERNAL_CONTENT_URI, values);
        OutputStream os = getContentResolver().openOutputStream(uri);
        os.write(jpegByteArray);
        os.close();

        Logger.info("MediaStore Inserted URI:" + uri.toString());

        return uri;
    } catch(Exception ex) {
        Logger.error(ex, "Failed to save the Bitmap file. FilePath: %s", filePath);
    }

    return null;
}

You'll have to notify the media scanner to capture metadata of the newly created files. Apps like Gallery work on the metadata database and not directly on the filesystem.

Programmatically you'd use MediaScannerConnection.

Since you're working with adb, you can send a broadcast to invoke media scanner.

Media scanner runs as part of the boot sequence so that's why it works after reboot.
