I would like to know if SNMP is supported in Android(2.1)?
If it is not available, is it possible to port the snmp source for Android?(some pointers plz..)
If it is available, how can I test the presence of it in my device.
All pointers are welcomed.
Thanks,
Sen
SNMP4J 2.x can be directly used on Android without changing its sources. The logging can be set to a simple console logger by calling
static {
LogFactory.setLogFactory(new ConsoleLogFactory());
ConsoleLogAdapter.setDebugEnabled(true);
}
in your root activity. Of course, you can implement a Android Logging Adapter too and register it as shown above.
I know this is a really old question, but I was doing exactly what you're asking. The short answer is no, by default, SNMP is not supported on android 2.1. Because it isn't available, what I wound up doing was grabbing snmp4j's source code, and sticking it in android and making my own library. There are libraries (snmp4android comes to mind) but I found that it lacked certain classes I needed and did not have the whole snmp4j.agent branch.
There are a few dependencies and a few libraries that android is missing but most of them pertain to the log4j class.
To remedy that, just convert/make the switch to something like slf4j, which is a small logging library that you can include with your application.
I hope that answers some of your initial questions, and I hope this is still relevant even if it is an old question.

We have a setup where we want to use https://ship.io/ as our cloud-based continuous-integration server.
However we also want to have some kind of static code analysis (preferably SonarCube but that is debatable), which isn't supported officially by ship.io.
The Projects are classic mobile Projects (Android and iOS).
I have seen some posts of people mentioning that they managed to setup this kind of configuration. SonarCube just has released a gradle plugin http://www.sonarsource.com/2015/06/15/sonarqube-gradle-1-0-released/ so the Android part should be doable.
However at the moment i have no idea what would be the best way do do this for the iOS part of the project.
We already contacted the ship.io team on this issue but did not recieve a response yet.
Any suggestions/insights on this?
My name is Tim Rosenblatt and I'm one of the senior engineers here at Ship.io. I'm not sure why you didn't get a reply from our support email, and I'm glad you posted about this here.
As Viktor mentioned, we definitely support custom scripts. You absolutely can run whatever you like during your build process with this type of step.
I've got a few links that should be helpful for you in getting SonarCube added to your Ship job, but you can definitely get in touch with us if anything isn't clear enough for you. You can use the in-app support icon at the bottom right of your dashboard, or just email me personally -- tim at ship dot io

Thanks!
You should be able to write a script (bash, ruby, ...) which runs your static code analysis and then call that script on your own Mac or on any CI which supports running custom scripts. AFAIK ship.io does support this, our service (https://bitrise.io/ - CTO here) certainly does.
I am creating an app showing local events for android. I was hoping to use the Eventful API, since that came with its own java-based client library. However, I'm not sure if it's fit for Android, since I know a lot of these java based client libraries use stuff Android doesn't support.
So, does anybody know if it works?
My entire project is available # github if you want to check it out for yourself.
The API is found here.
Android does not have have issues with Java client libraries. It is build on top of standard Java, and can use all of the framework features.
Furthermore, it looks like this API offers a RESTful interface, which is for sure supported by Android.
Bottom line, I do think you can use this API in Android without issue.
I'd say the easiest way is to compile and run an application that embeds the library and tests a few methods.
Typically, you may have issues with the way the networking is handled. There are 2 main ways in android to do HTTP, the Java and the Apache way, I think the Java URL API is fully supported and very close to the actual Java version, but the Apache has some hidden differences.
The main risks you'll have are A/ that it uses classes or packages that are not present on Android. B/ that a class does not behave as expected, which does happen from time to time, as the Android implementation is entirely specific.
Apparently you have already tried to run an android app with the library included? Did you encounter a specific error? If you, can you post the stacktrace?
Is "AndroidAnnotations" reliable? I've searched it but couldn't find many articles on it(reviews or tutorials).
I've been considering using this library in my project which already has quite lots of users. Before adopting it, I need a good reputation on it. So my concerns mainly are,
Are there famous products using this library?
Can I say it's stable enough to adopt it for my big project?
Will it be maintained well? (bug fixes, etc)
Thanks in advance.
I am the lead developer of AndroidAnnotations. Let's answer your questions:
Can you rely on AndroidAnnotations?
I think so. AndroidAnnotations is a compile time framework which generates code. The generated code is readable java code, which means that if you need to understand what happens, you can. No magic happening at runtime => you are in control.
We try to maintain a list of external articles / tutorials here.
Are there famous products using this library?
Let's be honest: I don't know. Matthias Kaeppler from Qype talked about AndroidAnnotations at DroidCon London 2011. The frontpage lists the applications that we know for sure are using it. I know there are way more people using it because they ask for enhancements and report bugs, but they usually don't let us know when they publish an app. And of course, the idea of "writing clean and maintainable Android code" is not yet very common in the Android community.
Can I say it's stable enough to adopt it for my big project?
We are using it in our own apps, and we find it perfectly stable. So I would answer yes, but I think you should just try it :-) . Download the 2.2 RC2 (will be released stable soon), follow the instructions and see for yourself. You can do progressive enhancement, and start enhancing only one or two activities. See how it fits you, and let us know if anything goes wrong. And if you do release an app with AndroidAnnotations on the Android market, please let us know, we'll update the front page.
Will AndroidAnnotations be maintained?
Yes, it will. Although it started as a personal project, AndroidAnnotations is now sponsored by a company, eBusiness Information. This company employs people (including me) to work on AndroidAnnotations, with the aim of making it a major Open Source Android framework.
As you can see here and there, we are adding a lot of new features for the 2.2 release. And you won't find a lot of open Defects in the issues, because we concentrate on fixing any bug before adding new features.
Is there a handy-dandy equivalent to org.apache.commons.beanutils.PropertyUtils on Android?
I can't seem to use bean utils in my android app due to some dependencies on PropertyDescriptor,and IndexedPropertyDescriptor. So I'm wondering if there are any alternatives?
Basically all I want to do is use a method name as a string "someMethod" and feed that into setMethod(anObject, "someMethod", value), much like PropertyUtils does; but without having to resort to the nasties of reflection...
Or are my hands tied and I need to use Reflection?
There is bridge library which works on Android: android-java-air-bridge.jar. Just include into project path and use all apache beanutils features in your Android project as you could use in ordinary java application. Moreover, there are lot of other classes which moved to this Android supporting library. Look at the list.
There is a possibilty to use libraries or write own code depending on the PropertyUtils. But it sure isn't dandy. You can get the general idea about what has to be done in this thread.
There are apparently some projects who have successfully solved the issue, so you can study thier solution. Take a look at Drawingpad-base and libgdx. You can find PropertyUtils in the package com.madrobot.beans in the first project and com.badlogic.gdx.beans in the second.
I am a beginner on android platform, and I want to build a tracerouting app. So these are my queries:
Is it possible to make such an application in Android? if possible then guide me the way that I follow.
Does Android support low-level programming to capture ICMP packets? or do I need to add some kind of JAR (in java) or some other libraries to support this application?
In Java, there are JPCAP and docjar etc kind of libraries that we can import in our IDE or Eclipse so that Java support for making such kind of API's?
I need valuable suggestions.
It's quite late - but someone might see it.
i found this one and it worked for me:
https://github.com/olivierg13/TraceroutePing
The simplest way I can think of is to just check for the traceroute Linux application, execute it, and parse its output.
Android has full networking support, however, Java doesn't expose an interface to alter the IP header. Hence, manually crafting ICMP packages is out of the question (JPCAP is no help here, since it relies on libpcap, which I suppose you won't find on any vanilla installation).
Another possible solution is to use the NDK and create a small library that handles the low-level number crunching. However, I'm not sure if the NDK would allow you to use setsockopt.
This is working pretty well for me, you may have to filter out the string results.
To add this library, you have to download or clone the git repository and implement the folder "library" just as he does in the other module "app" for it to work properly.
