Guava-使用向导

北战南征 提交于 2019-12-02 20:27:23
Guava中包含了Google的一些核心类库:比如集合,缓存,并发包,常用注解,字符串处理,I/O等等。这些工具类被谷歌的工程师们经常用到。 但是通过查阅文档不是一个有效的学习类库的方式。这儿, 我们尝试提供一写方便查阅的比较常用的Guava工具类。 基础工具: 更加舒适的使用java。 Using and avoiding null : null 可不能被含糊, 能引起一些莫名的错误。许多Guava工具拒绝null并且会快速失败,而不是盲目的接受null。 Preconditions : 非常容易的为你的方法做个先决测试。 Common object methods : 简单的实现Object方法,像 hashCode() and toString() . Ordering : Guava强大的比较类。 Throwables : 简化传播 , 检查异常和错误。 Collections: Guava对JDK集合的扩展。Guava中用的比较多的地方 。 Immutable collections , 防御性编程,常量集合, 提高效率。 New collection types , 一些JDK Collect ion s中没有解决的 : multisets, multimaps, tables, 双向maps等 。 Powerful collection utilities , 一些

Should i rebuild a dependent lib after system update?

我只是一个虾纸丫 提交于 2019-12-02 16:04:43
问题 I have some fear when i update my system libraries. For example, i made make && make install for a custom lib (i.e. libhell , there is no this library in repo) that depends on libssl-dev>0.5. Then apt offers me to update libssl-dev . Should i rebuild libhell against new libssl-dev ? Always it worked fine after updates and without rebuilds, but what about binary safety? All the time i build own packages on bin-dist systems i feel i'm doing something wrong... 回答1: This is why package systems

Python - what is the libs subfolder for?

For me, it's located at C:\Python33\libs. For reference - this is not the same folder as C:\Python33\Lib - note the capitalization and lack of an 's'. On one computer I was working on, I simply dropped a .py file into the libs folder and could import and use it like a library / module (sorry, I don't really know terminology very well), regardless of where the project I was working on is. However, in trying to duplicate this on another machine, this doesn't work. Attempting to import simply gives a "no module named X" error. So, clearly I'm misunderstanding the purpose of the libs folder, and

Have no libs directory in Android Studio

我只是一个虾纸丫 提交于 2019-11-28 15:11:41
I need help in creating libs in Android Studio for my project, mine are not auto generated. When I want to create a folder, it gives me lots of options, like AIDL, Assets, JNI, Java, Java Resources, Renderscripts and Res folders. I chose Res and added a libs folder but it didn't show up on my file structure on the left. Can anyone help me? I wanted to add a JAR file but I can't find libs to put in. dangalg The solution for me was very simple (after 10 hours of searching). Above where your folders are there is a combobox that says "android" click it and choose "Project". Click the left side

How to build the achartengine library after modification?

♀尐吖头ヾ 提交于 2019-11-28 11:52:29
问题 I modified the achartengine code to optimize it for myself but how do I build the lib in AndroidStudio? (I'm new in coding) I found a build.xml file, so it should be possible to run ant jar to create the lib, but how do I do that...? or is there a better way? 回答1: If anyone is still interested in this (in 2019) ... There are copies of achartengine on github, and the primary seems to be this: https://github.com/ddanny/achartengine The project has both build.xml and pom.xml files, so it should

Gradle native libraries not found on device but present in apk

冷暖自知 提交于 2019-11-28 01:20:33
My application uses Here SDK and Twilio SDK . Both uses native libraries (Here SDK with native libraries locally plugged in from /libs and /jniLibs folders, Twilio SDK plugged in from jCenter). But on Android 5.1 Here SDK throws exception "MISSING LIBRARIES: libMAPSJNI.so" although this library present in result APK. I opened folder where my program is installed on device and compared content in two cases: with or without Twilio SDK. The difference is that when connected Twilio API folder /lib is a file, and for obvious reasons, the loader can not see inside it native libraries needed

Adding Joda Time

…衆ロ難τιáo~ 提交于 2019-11-27 13:55:12
问题 I am building an app that uses time. I decided to use Joda time. I am trying to add joda time to my app. I have no experience with adding .jar files to the libs. I followed these steps(see bottom), or so I thought. My project is showing no errors, but when I run a simple test: DateTime test = new DateTime(); I get a force close and the following error: Could not find class 'org.joda.time.DateTime', referenced from method xxxx java.lang.NoClassDefFoundError: org.joda.time.DateTime These are
