SQLite being accessed by GCM

I need my GCM, when I receive a message, save the information in the database, but it is giving error, it must be because the application is not open. Does anyone know what I should do? I have the following method within my GCM CommonUtilities:

public static void SaveDatabase(int remetente, int destinatario, String msg, Context context){
     try{

      db = dbHelper.getWritableDatabase();

      ContentValues values = new ContentValues();
      values.put(DbHelper.C_REMETENTE, remetente);
      values.put(DbHelper.C_DESTINATARIO, destinatario);
      values.put(DbHelper.C_MSG, msg);
      try{
        db.insertOrThrow(DbHelper.TABLE, null, values);
      }finally
      {
        db.close();
      }
      GCMIntentService.generateNotification(context, "SALVOU");
    }catch(Exception e)
    {
        GCMIntentService.generateNotification(context, "ERRO: " + e.toString());
        //GCMIntentService.generateNotification(context, e.getMessage());
      //Log.e("error sqlite", e.getMessage());
    } 
  }
