我正在开发将数据保存到SQLite并将其同步到mysql数据库的android应用。 Internet可用时，代码运行良好，但是当没有Internet可用时，它将在MySQL数据库中插入4次。请参阅下面的代码 请帮助谢谢。我指的是此link的代码。请帮助您。

public class NetworkStateChecker extends BroadcastReceiver {
private Context context;
private DatabaseHelper db;


@Override
public void onReceive(Context context, Intent intent) {

    this.context = context;

    db = new DatabaseHelper(context);

    ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetwork = cm.getActiveNetworkInfo();

    //if there is a network
    if (activeNetwork != null) {
        //if connected to wifi or mobile data plan
        if (activeNetwork.getType() == ConnectivityManager.TYPE_WIFI || activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE) {

            //getting all the unsynced names
            Cursor cursor = db.getUnsyncedNames();
            if (cursor.moveToFirst()) {
                do {
                    //calling the method to save the unsynced name to MySQL
                    saveName(
                            cursor.getInt(cursor.getColumnIndex(DatabaseHelper.COLUMN_ID)),
                            cursor.getString(cursor.getColumnIndex(DatabaseHelper.COLUMN_NAME)),
                            cursor.getString(cursor.getColumnIndex(DatabaseHelper.COLUMN_POS)),
                            cursor.getString(cursor.getColumnIndex(DatabaseHelper.COLUMN_CODE))
                    );
                } while (cursor.moveToNext());
            }
        }
    }
}
private void saveName(final int id, final String name, final String code, final String pos) {
    StringRequest stringRequest = new StringRequest(Request.Method.POST, MainActivity.URL_SAVE_NAME,
            new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {
                    try {
                        JSONObject obj = new JSONObject(response);
                        if (!obj.getBoolean("error")) {
                            //updating the status in sqlite
                            db.updateNameStatus(id, MainActivity.NAME_SYNCED_WITH_SERVER);

                            //sending the broadcast to refresh the list
                            context.sendBroadcast(new Intent(MainActivity.DATA_SAVED_BROADCAST));
                        }
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {

                }
            }) {
        @Override
        protected Map<String, String> getParams() throws AuthFailureError {
            Map<String, String> params = new HashMap<>();
            params.put("name", name);
            params.put("code", code);
            params.put("pos", pos);
            return params;
        }
    };

    VolleySingleton.getInstance(context).addToRequestQueue(stringRequest);

}
