how to update the android app in android market

I saw many question addressing this issue but still i have some doubts...

I followed the steps given by Chris Smith in this question 开发者_如何转开发

• Increase the value of the android:versionCode attribute of the <manifest> element in your AndroidManifest.xml
• Build, sign, zipalign the apk as you did originally
• Go to http://market.android.com/publish/Home
• Click on the app name
• Click on [Upload Upgrade]

But no where i could found [Upload Upgrade] option in developer console as he told. Please see the image below

Anyone knows what was the problem?

Google changed the upgrade GUI so the post that you are referring to is no longer valid. From your screen

• click 'save' button
• click 'switch to advance mode' it will show multiple version of your APKs
• you will be able to 'activate' the desired version.
