Discovering Flurry

First, I just want to point that I'm not in any way affiliated with Flurry, and blablahbla.... :
NO I DON'T KNOW THOSE GUYS... I just tried their tool !!

What is Flurry ?
When you launch a new application, it's always great to have some feedbacks on it.
There are many different feedbacks : error reports, user evaluations, user mails, online scores, or... 'some' statistics.
It's useful for two different things :
* for your ego, it's always a good thing to have some feedback that basically says that people are trying your application. It's even better if they say they like it ! Even if you don't have the super-developed ego that most developers have, having this kind of information is good for motivation, and helps you improve your application ! As strange as this point may sound, I think it is really important specially if you are an independant developer, as you will need some motivation !
* It's  also crucial if you want to know who your application users are, and how they use it ! It will let you analyse what is good in your application, what are the weaknesses, where to put your efforts in order to satisfy your users...

As I had embedded AdMob ( the now famous ads provider for Android ), I already had some sort of feedback for a while : the number of ads impression for every day. It gives me an indication on how many users are playing my game, and on how this number is evolving.

Flurry ( actually Flurry Analytics ) gives you a lot more statistics on the users and on how they use your application.

How to integrate Flurry ?
The integration of Flurry is really easy.
Create an account on their web site, register your application, add the jar in your application, and copy paste some code on each activity, and voilà ! your first integration is done !!
I also added some special events, in order to know which activity was started, and which game mode was used ( the game has 6 different game modes ).
This is a very good point with this middleware !!

What indications Flurry provides you ?

Flurry provides you informations on :
* users : how many users you have, whether they keep on using your application, how many times did they use it every day, how many sessions you have, how long is a session, and where do they come from.
* Technical : info on which phone was used, which carrier, which firmware, and a simple error reporter is provided ( that does not seem to interfere with mine !! )
* Events : Events are special signals you put in your applications and that are collected by Flurry. You basically do whatever you want with them !

By the way, the information is nicely presented, with some beautiful graphes that make it easy to get the information quickly !

How useful is this information ?

To be honest, I'm kind of fascinated by all this feedback !
All of it is not useful, but it's really interesting to navigate throw this pages and graphes on my game !

In the user pages, you can see the evolution of the way your application is used : if it keeps on increasing.
For instance, I really did see the Chrismas effect : the number of new users has really increased after the 25 !

Welcome to all of those new Android Owners !!

The technical part is also really interesting :
* The firmware versions are divided in about one big third Android 1.5, another third Android 2.0.1, and another little third is Android 1.6...
The rest ( yes, the rest after the 3 thirds... ) is Android 2.0 and Android 2.1. That means that if you want to bypass one of this Android version, you are limiting your audience in large proportions !

* The devices : The droid is the big winner here, with about 1/3 of the devices used. Then the HTC Hero / Eris, the HTC G1/Dream and the MyTouch/Magic...
We can observe that the french version of my game, obviously mainly played in France shows a very different picture :
WordProspector version ( essentially played in the US )

"Chasseur de mots" ( the french version, essentially played in France )

We can see that Samsung - that had shipped the Galaxy a long time ago in France - is much more present, and that Motorola is surprisingly unpresent !
Another funny thing : in the french version there is a ... BlackBerry 8230 : I guess someone played with home-made OS and changed the Phone_Model string !

Last point : the events
The events can clearly be the most important point in Flurry if you use them wisely.
If you want to know something specific on how your users are using your application, Events are for you !
For instance, in my game, I registered which game mode the player were playing.
Personally, I always play the game in Full Game mode, 1 minute, but I discovered that  most people played in 'simple mode', for 1 minute.

Conclusion :
Clearly, users want some quick game : both 'simple game' and 'full game' are played.
And the 2 minutes and 3 minutes games are far from being negligeable ( at that point, I was still wondering if I had developed that for more than 3 users :)

Conclusion : was it worth it ?

First, I want to point that, obviously, Flurry your application to open network and localization authorizations. I don't think it is a real issue ( and in my case, I already needed these authorizations for AdMob), but it may be something that you don't want.

If you don't mind opening these authorization, and don't have any other way to get feedbacks, I think Flurry is really a choice to consider.
It's so simple to use and gives you lot of information.
Now I regret that it is not more flexible with the information it gives. I would like to have a way to create my own requests. For instance, I would like to know how the firmwares are distributed on the G1, but you don't have that much freedom ( even if there are a lot of information already available ).
A custom system done by myself would be more flexible. But, let's be honest : I won't invest time enough  to have something as elaborate as their tool ! ( not to mention the fact that I don't know how to present the data in such a nice way ).

I encourage you to also try Localytics. We give you the flexibility you're looking for--you can chart any metric against any other metric.

Our new event attribute feature enables even more interesting options, such as auditing your AdMob fill and click rates.

You can read more about these new features on our blog post:

To be honest, reports I get in Flurry are absolutely worthless.

I encourage you to try anything else!

If you want to have a go with an open source solution with a pinch of simplicity and great user interface, I'd suggest that you use Countly ( :)

You can even install it on your own servers, and extend it to your needs as you wish.

Thanks in Advance

@Vishal :
There is nothing complex with Flurry, as far as I know.
I think all is explained in their SDK documentation.

I'm just doing this :

// For Flurry :
public void onStart()
FlurryAgent.onStartSession(this, GetFlurryID() );
FlurryAgent.onEvent( "MyString");
public void onStop()

Thanks a lot AndroidBlogger

I've done the same thing in my code but may I know for what is Flurry about ?? I mean to ask its for Analytics only or will it be able to show an ad banner (Like in AdMob) on Android App Screen.??

And When I'll get update for Analytics for whatever events I am putting as Log on Flurry Site..

And By the way I needed the code for Addind Ad-Banner in App not for Analytics ..Can u please post it..??

Thanks a tonne for ur kind reply & Thanks in Advance

@Vishal :
As far as I know, Flurry is just an Analytic product, so it lets you understand how your users are using your application.

If you want some ads, you have to use a ads provider, like Admob.
