How to read contacts in Android using Realm?

问题 I can't find any solutions to read contacts from Android and save them in Realm. Anyone done that before? I know that I will have to use Contacts Provider , but this is all I know. AFAIK, Realm doesn't support Cursor so...what else? edit: realm.executeTransaction(new Realm.Transaction() { @Override public void execute(Realm realm) { Contact realmContact = new Contact(); String filter = "" + ContactsContract.Contacts.HAS_PHONE_NUMBER + " > 0 and " + ContactsContract.CommonDataKinds.Phone.TYPE

How do I view my Realm file in the Realm Browser?

问题 I've just discovered Realm and wanted to explore it in more detail so I decided to create sample application and having a mess around with it. So far so good. However, one thing I haven't been able to work out just yet is how to view my database in the Realm Browser. How can this be done? 回答1: Currently the Realm Browser doesn't support accessing databases directly on the device, so you need to copy the database from the emulator/phone to view it. That can be done by using ADB: adb pull /data

Shiro的原理及Web搭建

shiro(java安全框架)     以下都是综合之前的人加上自己的一些小总结     Apache Shiro是一个强大且易用的Java安全框架,执行身份验证、授权、密码学和会话管理。使用Shiro的易于理解的API,您可以快速、轻松地获得任何应用程序,从最小的移动应用程序到最大的网络和企业应用程序。 Shiro 主要分为来个部分就是认证和授权,在个人感觉来看就是查询数据库做相应的判断而已,Shiro只是一个框架而已,其中的内容需要自己的去构建,前后是自己的,中间是Shiro帮我们去搭建和配置好的     个人认为需要看一下其中的一些源码,更有帮助的深入的去了解Shiro的原理。 Shiro的主要框架图: 方法类的走向: 对一些其中的方法的简单说明: Subject Subject即主体,外部应用与subject进行交互,subject记录了当前操作用户,将用户的概念理解为当前操作的主体,可能是一个通过浏览器请求的用户,也可能是一个运行的程序。 Subject在shiro中是一个接口,接口中定义了很多认证授相关的方法,外部程序通过subject进行认证授,而subject是通过SecurityManager安全管理器进行认证授权 SecurityManager SecurityManager即安全管理器,对全部的subject进行安全管理,它是shiro的核心

shiro权限管理

参考:https://blog.csdn.net/qq_39874546/article/details/79081950 https://www.cnblogs.com/moonlightL/p/8126910.html 1. Shiro入门 ApacheShiro是一个功能强大且易于使用的Java安全框架,提供了认证,授权,加密,和会话管理。 Shiro有三大核心组件: Subject:即当前用户,在权限管理的应用程序里往往需要知道谁能够操作什么,谁拥有操作该程序的权利,shiro中则需要通过Subject来提供基础的当前用户信息,Subject 不仅仅代表某个用户,与当前应用交互的任何东西都是Subject,如网络爬虫等。所有的Subject都要绑定到SecurityManager上,与Subject的交互实际上是被转换为与SecurityManager的交互。 SecurityManager:即所有Subject的管理者,这是Shiro框架的核心组件,可以把他看做是一个Shiro框架的全局管理组件,用于调度各种Shiro框架的服务。作用类似于SpringMVC中的DispatcherServlet,用于拦截所有请求并进行处理。 Realm:Realm是用户的信息认证器和用户的权限人证器,我们需要自己来实现Realm来自定义的管理我们自己系统内部的权限规则

App size increase due to realm android

问题 I am adding some data into realm database after every 15 sec through a service. After a whole night, the size of app become 350mb due to realm, its confirm.. But if i delete that data from realm, after some condition, the data deleted but the size of app still shown 350mb. The question is why the app size is not shrinking now. 回答1: Realm currently doesn't automatically reclaim the space used by your database, but it will be reused if you later add data again. If you wish to free the disk

问题 For learning purposes i'm creating an android app by using Realm and the Edinburg Festival Api. It's going pretty well except for one problem. I'm using the following to convert the retrieved JSON to RealmObjects: public void onResponse(final String response) { realm.executeTransactionAsync(new Realm.Transaction(){ @Override public void execute(Realm realm) { // Update our realm with the results parseImages(); realm.createOrUpdateAllFromJson(Festival.class, response); } } } This works fine

Shiro - 认证

认证是Shiro最基本的工作! 先从代码开始,运行后再慢慢研究。 以下是我添加的dependecies: <!-- shiro --> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-core</artifactId> <version>${shiro.version}</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring</artifactId> <version>${shiro.version}</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-web</artifactId> <version>${shiro.version}</version> </dependency> 在资源目录下创建shiro.ini,文件内容为: [users] king=t;stmdtkg 写一个main方法: package pac.testcase.shiro; import org.apache.shiro.SecurityUtils;
