I have in my app a BroadcastReceiver which is called each X seconds by an ALARM_SERVICE. This BroadcastReceiver calls to another service which is run by an AsyncTask (to try to avoid to block the main thread) but I have received some ANRs from my users and the log that google provide me I'm not able to read it if I'm honest. Can someone help me to understand the log and to solve the is
我在我的应用程序中有一个BroadcastReceiver,它每隔X秒由一个ALARM_SERVICE调用。 这个BroadcastReceiver调用另一个由AsyncTask运行的服务(为了避免阻塞主线程),但我收到了一些来自我的用户的ANR以及谷歌提供给我的日志,我无法阅读它,诚实。 有人能帮我理解日志并解决问题吗? 这是Google为我提供的11个日志中的1个: DALVIK THREADS :(互斥锁:tll = 0 tsl = 0 tscl = 0 ghl = 0) "main" prio=5 tid=1 WAIT | gro
I'm sorry for the long post, but I think this is the only way to explain whats happening... I'm looking for help after a lot of research with no answers... A big problem I think... So this web app schedule a local notification based on a time picker that the users interact with.. I'm using cordova and jquery mobile multi-page system... It changes from page to page by div IDs, the na
对于这篇长文章,我感到抱歉,但我认为这是解释发生了什么的唯一方法......经过大量研究,我没有找到答案,我正在寻找帮助......我认为一个大问题...... 所以这个Web应用程序根据时间选择器安排一个本地通知,用户与之交互..我使用的是cordova和jquery移动多页系统......它通过div ID在页面间切换,导航看起来像这样:index.html,index.html#page2,index.html#page3 ..本地通知是Cordova Katzer本地插件的java插件。 该
My team got handed over some server side code (in Java) that generates random tokens and I have a question regarding the same - The purpose of these tokens is fairly sensitive - used for session id, password reset links etc. So they do need to be cryptographically random to avoid somebody guessing them or brute force them feasibly. The token is a "long" so it is 64 bits long. The c
我的团队已经交出了一些生成随机令牌的服务器端代码(使用Java),并且我有一个关于相同的问题 - 这些令牌的用途相当敏感 - 用于会话ID,密码重置链接等。因此,它们确实需要密码随机,以避免有人猜测它们或蛮横逼迫它们。 令牌是一个“长”,所以它是64位长。 该代码当前使用java.util.Random类来生成这些令牌。 java.util.Random的文档([http://docs.oracle.com/javase/7/docs/api/java/util/Random.html][1])明确指出
Areas, in ASP.NET MVC, are handy for breaking a site into smaller, manageable components at a higher level than controllers. They are like mini-MVC pieces within a web application. Is there an equivalent concept in any Java MVC framework to ASP.NET Areas? If not, are there any suggestions on best practices when emulating their functionality in a Java MVC framework? Try Spring MVC. This ma
ASP.NET MVC中的区域可以方便地将站点分解为比控制器更高级别的更小,可管理的组件。 它们就像Web应用程序中的迷你MVC片断。 在ASP.NET区域的任何Java MVC框架中是否存在等同的概念? 如果没有,在Java MVC框架中模拟它们的功能时,有没有关于最佳实践的建议? 试试Spring MVC。 这可能会实现你的愿望。 查看JSP Tiles和Velocity模板。 瓷砖应该看起来与地区相似。 看看这个Web框架的Java:playframework
Most OO languages prefix their interface names with a capital I, why does Java not do this? What was the rationale for not following this convention? To demonstrate what I mean, if I wanted to have a User interface and a User implementation I'd have two choices in Java: Class = User, Interface = UserInterface Class = UserImpl, Interface = User Where in most languages: Class = User,
大多数OO语言都以大写字母I为前缀,Java为什么不这样做? 不遵循这个惯例的理由是什么? 为了演示我的意思,如果我想要一个用户界面和一个用户实现,我会在Java中有两个选择: Class = User,Interface = UserInterface Class = UserImpl,Interface = User 在大多数语言中: Class = User,Interface = IUser 现在,你可能会争辩说,你总是可以为用户实现选择一个最具描述性的名称,问题就会消失,但是Java将POJO
How does one go about and try to find all subclasses of a given class (or all implementors of a given interface) in Java? As of now, I have a method to do this, but I find it quite inefficient (to say the least). The method is: Get a list of all class names that exist on the class path Load each class and test to see if it is a subclass or implementor of the desired class or interface In
一个人如何去尝试在Java中查找给定类(或给定接口的所有实现者)的所有子类? 到目前为止,我有一个方法来做到这一点,但我觉得效率很低(至少可以这么说)。 该方法是: 获取类路径中存在的所有类名的列表 加载每个类并测试它是否是所需类或接口的子类或实现者 在Eclipse中,有一个称为类型层次结构的很好的功能,可以非常有效地显示这一点。 人们如何去编程地做呢? 除了你所描述的之外,没有别的办法可以做到。

I want to encrypt video on the fly that android camera captures. So I need to tell android MediaRecorder to write it video stream to my CipherOutputStream . The problem is MediaRecorder.setOutputFile() method accepts only FileDescriptor and there is no way to get encrypting file descriptor from CipherOutputStream. So my question is how can I either emulate FileDescriptor to receive data write
我想要根据Android摄像头捕获的视频加密视频。 所以我需要告诉android MediaRecorder将它的视频流写入我的CipherOutputStream 。 问题是MediaRecorder.setOutputFile()方法只接受FileDescriptor并且无法从CipherOutputStream获取加密文件描述符。 所以我的问题是如何模拟FileDescriptor来接收数据写入并手动进行加密,或者以某种方式说服MediaRecorder将视频流传输到CipherOutputStream 。 你可以使用LocalServerSocket和L
I'm writing a big Red5 Java application for the web. Red5 a Flash Media Server alternative that is java based and is written with the spring framework. I want to have many versions of my application online, each with different behaviors and different classes enabled or disabled. I'm looking for a way to convert my code into modules based code that will allow me to remove/add modules/
我正在为Web编写一个大的Red5 Java应用程序。 Red5是一个基于Java的Flash Media Server替代品,用Spring框架编写。 我想在线有很多版本的应用程序,每个版本都有不同的行为和不同的类别启用或禁用。 我正在寻找一种方法将我的代码转换为基于模块的代码,这将允许我从主应用程序中删除/添加模块/功能。 我知道OSGI http://www.springsource.org/osgi,但它说它需要一个SpringSource dm服务器,我不知道它将如何在red5中一
i am trying to build an artifact from a modified maven project imported in intellij (v2016.2). Have managed to: (1) Import/build a multi module maven project in intellij (2) Successfully built/run an artifact as a single jar from the project (3) Modified maven project by writing new classes with extra depedencies (via changing project's structure and adding new maven dependencies*)
我试图从intellij(v2016.2)中导入的修改后的maven项目中构建一个工件。 已设法: (1)在intellij中导入/构建一个多模块maven项目 (2)成功将项目构建/运行为项目中的单个jar (3)通过编写具有额外依赖性的新类来修改Maven项目(通过更改项目结构并添加新的Maven依赖关系*) (4)成功构建并运行修改后的项目 然而,当我尝试从修改过的项目中运行一个工件(并且即使它包含了jar中的所有依赖项),它也完全忽略了
