I was able to implement Pause/Resume functionality using the following implementation via the Android DownloadManager and Downloads Content Provider:

private boolean resumeDownload(Context context, String downloadTitle) {
    int updatedRows = 0;        

    ContentValues resumeDownload = new ContentValues();
    resumeDownload.put("control", 0); // Resume Control Value

    try {
        updatedRows = context
            .getContentResolver()
            .update(Uri.parse("content://downloads/my_downloads"),
                resumeDownload,
                "title=?",
                new String[]{ downloadTitle });
    } catch (Exception e) {
        Log.e(TAG, "Failed to update control for downloading video");
    }

    return 0 < updatedRows;
}

private boolean pauseDownload(Context context, String downloadTitle) {
    int updatedRows = 0;

    ContentValues pauseDownload = new ContentValues();
    pauseDownload.put("control", 1); // Pause Control Value

    try {
        updatedRows = context
            .getContentResolver()
            .update(Uri.parse("content://downloads/my_downloads"),
                pauseDownload,
                "title=?",
                new String[]{ downloadTitle });
    } catch (Exception e) {
        Log.e(TAG, "Failed to update control for downloading video");
    }

    return 0 < updatedRows;
}
