Is it possible to use CPLEX in Android application?

I just want to know if there is any libraries that I can use, or maybe include some .jar files. I don't know how to do it or even start ,any help or clarification whether it is possible in the first place or not ?
I already saw this forum,but nobody did answer so I am not sure.

at https://www.ibm.com/support/pages/detailed-system-requirements-ibm-ilog-cplex-optimization-studio
you may find all available ports for CPLEX
For ports that are not there, you may call CPLEX in the cloud :
CPLEX is available in the cloud in docplexcloud and wml
https://developer.ibm.com/docloud/
https://www.ibm.com/cloud/blog/announcements/decision-optimization-now-available-in-watson-machine-learning-service

You can use python on android and run CPLEX from the IBM cloud
in your app install : docplex and docloud (as python modules).

you do the tests with the trial version : https://developer.ibm.com/docloud/try-docloud-free/

How to get the Android logs remotely?

Because Google told me to, I've been using Log.I , Log.E etc commands throughout my code during development.
This of course has been quite helpful during testing and debugging.
However an application that I have deployed seems to be crashing sometimes, something which I cannot replicate.
Is there a way to retrieve the logs created through the aforementioned commands from the device? I've been through the whole google development site, but there seems to be nothing on the subject (or I am missing something)
Thanks in advance for any help you can provide

Try to look at ACRA and Crashlytics, this tools should help you.

Beginning Android 4.0 Application Development by Wei-Meng Lee Eclipse Version Error

I am a android beginner. I am going through the book listed in the title. I haven't even made it past the first chapter without running into problems. I have installed the latest version of Eclipse. However, the examples shown in the book are not much like my version. For instance, this main.xml file that's supposed to be in the layout folder is not there. The "New Android Project" dialog box is arranged very differently and the package explorer is called project explorer. Is there a way to get this kind of eclipse in the book? Or do I just have to interpret it best I can? Any help would be much appreciated! This question has been down voted and closed by another user. Could someone please tell me why? I am just trying to get some help.

As different Android APIs(ICS, JB, etc.) are released, they sometimes change the ADT (Android Development Tools) for Eclipse. The ADT is plugin for Eclipse. This plugin is what gives you all those neat buttons in the toolbar and the XML layout interaction.
The book you are reading was designed for Android 4.0(Ice Cream Sandwhich). As of right now, Google has released up to Android 4.2.2(JB 4.2). There has been some significant changes to the ADT going from ICS to JB, but in my opinion, they are for the good. Lots of really neat and new features. Here is a Google resource explaining the different API releases for Android: http://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels
I would say continue reading the book as it will teachs you the basics of Android, but when you want to do some in depth coding, that book isn't going to be very useful and you may have to do a little research online. Reason is, Google releases at least two new versions of Android every year. Every version changes, and adds new features. In other words, the book you are reading is already out of date. Android OS development moves way to fast for authors to keep updating their books.
To answer your question, your probably going to have to interpret it the best you can since, most likely, by June/July, Key Lime Pie is going to out, and the ADT your using NOW will be outdated. You should really learn the fundamentals of Android OS and how it works in the background and how processes things. After that, everything else should be easier to learn.
An alternative to the book you are reading is this: http://developer.android.com/training/basics/firstapp/index.html. This is straight from Google and is constantly updated and tweeked. This will be the most updated and useful information on how to write Android apps.
Hope that helps!

Android app with automatic sync

recently, I've started the developing of a new app, and this app is in need of constant update. I know I can do it with alarms, but I think that a better way is to add my app to android automatic sync service (the one that is added gmail app and whatsapp for example).
I've looked for that topic, but couldn't find any answer about how to interact with that service. Can anybody provide me an example of how to accomplish it?
Thank you so much,
Vyrphan

Check out the SampleSyncAdapter code under the SDK samples. It will be in a directory akin to;
C:/Program
Files/Android/android-sdk/samples/android-10/SampleSyncAdapter/

Google IO Twitter Livefeed from a fresh install

I just dowloaded the Google IO Source code from here: http://code.google.com/p/iosched/ in order to understand the great UI of this app.
I also wanted to grab the code of the Twitter LiveFeed, but when compiling freshly downloaded code, I get a crazy UI:
I don't understand what's wrong as I didn't changed one line of the code!
Does this issue happens on other people devices?
Thank a lot.

I answer myself in case other people also searching for the answer:
http://twitter.com/#!/romannurik/statuses/69818965840506880
yes we used some custom Google
Realtime Search tweaks that I
explicitly removed from open source.
So that seem impossible for now... Or we will have to look for other alternatives
