    String newString = size.toString();



    //String path = getSharedPreferences(PREF_TAG, 0).getString(PREF_HOME,defaultHome);

    //File pathFile = new File(path);

        return path+size;
    else
        return defaultHome+size;
    }
   return defaultHome;
}

您可以使用String.valueOf()或Long.toString()方法将long类型的值转换为String类型。

String str1=String.valueOf(long_var);
String str2=Long.toString(long_var);
