Is there a simple way to check each time a user launches my game, to notify him if there is an update to my app? Maybe there is something built into Google Play?
Create Simple web service.when user run your app check local version with server (app version in device and app version in server).
if app version is new , notify to user .

I want to know what happens to users already installed applications, if i made any change in backend application and deploy module to app engine???
i.e i installed an application in play store yesterday with google storage backend in java. Now i wanted to add new feature to my existing app. but i am afraid if i did something wrong in backend application and deploy it to app engine, whether it will effect my installed application and users????
Your already published app will be the same as when you published. If you had any communication with backend app will expect that backend will be working.
You can change anything in your backend as long as old endpoints will be working. If you need to make bigger update and remove some of elements in backend your app you should check version of backend API in your app and notify user about needed update of app.
Best way to check if everything is working is simply run existing app and verify if everything is ok. If anything broke up prepare fixed version of app and publish to play market as soon as possible. Users will get notification about update of your app. In that case they will have not working app until update.
I want to make an application manager like Google Play that allows user to download APK file to her/his mobile phone and update any application when there is a new version.
So I need information how to start first step, how to notify the application if there is a new update is there Google API allow me to download APK file directly to the application server and update to the last version?
Any help information what I should use and shall not use are appreciated.
You could check every x minutes or when Internet connection appears if there is new version of Your application on server. You could also use Google Cloud Messaging to notify users that update appears.
I am a beginner on Android as I am working on developing a new Android app. In my project I have some problems when the user click on an icon, it should redirect him to dot net website I did in my code.

If you release your app in the Google Play Store the updates are managed automatically by Google. You can just release another version of the app in the Google Play Store and all users will be notified from Google that a new version is available.

If you release your app in the Google Play Store bugs will be reported automatically by Google to your Google-Mail Account.
Better to implement GCM push service in your application to send a notification about the update to all your application users.
http://developer.android.com/guide/google/gcm/index.html
This framework will give your application to support push notify the user from your server, and what you need to do in your application just track the received push and write a code to download new APk from server and install it automatically.
The second thing you asked about the Crash reports so the best option is use ACRA technology to get the your application report on server everything force close or logcat
Both are very easy to implement so enjoy!!
At first use GCM for push notifications like updates for your application.
Second useGoogle Analytics for any bug report crashes usage
I plan to publish my Android app on getjar.com . However, I am unable to see how the user would be notified of any updates. Does GetJar support app updates (i.e. would the user be notified of app updates when new versions are uploaded to getjar.com ?)
Thanks for asking, we actually just rolled out update notifications for Android apps. You can find out how to update your app here: http://blog.getjar.com/developer/howtoupdates/
If you have any questions, feel free to email me at Brian#getjar.com.
No, getjar doesn't but you can notify the user in the app that the update is available to download from getjar.You can set time in your app e.g after 24hrs check the server for updates.
If I have an app on the market with analytics API integrated , now i want to change the integrated API (analytics) to some other analytics API and update the build in market. I want the user forcefully to update the application. How can i do that?
Thanks in Advance
If your app uploaded on android market, and you update ur application with incremental version code. Users of application will be notified with update for application, but by no means user can be ask to update application forcefully.
You can't force users to update, unless the functionality of the app is reliant on something external (eg, a call to an URL) that you can deliberately break at the external end -- and even then, they could just uninstall the app instead of upgrading.
