I need your help. I created an app in Android Studio, then I created a second "page", well I created a second class.
But it says this class needs an default constructor. What shall I do?

I'm fairly new to java and android studio in general,and I'm trying to follow a tutorial on YouTube on how to make a simple android calculator by Andy York. I made it to part 2 of 2 until he started coding in MainActivity.java, when I noticed that ours were different and that I have stuff like "FloatingActionButton"and "SetSupportActionBar" which he doesn't have and which is confusing because if erase those then everything will mess up. I think it may have been because of an Android Studio update since his video? I'm trying to make everything neat like his but I don't know how. I hope this makes sense and any help would be appreciated. Thanks.
When creating new project in Android Studio use "Empty Activity" template instead of "Basic Activity". The "basic" one does add a lot of things, like a floating action button, which often isn't helpful.
Those are coming because you select a that theme. So, Select the Empty Activity. Then nothing will make problem .
is there someone who can help me to find a android code to create a kitchen >timer (I am a beginner)
As said in the comments, not sure why you didn't just search Google. However I'd advise using the inbuilt CountDownTimer class. Here is an example of how to set it all up:

Eclipse-PhoneGap Tutorial
I'm trying to implement a MenuBar (i need it always visible so the context menu is not useful !) in the bottom of every activity for my app.
I saw that the easy to use TabActivity is now deprecated...and so i didn't get yet ho should i use the Fragments "technology".
I already found some discussion...but there is any already implemented eclipse project i could download somewhere or any easy to follow tutorial?
The one i followed over here http://developer.android.com/reference/android/app/TabActivity.html was really incomplete.
I get some class cast exception due the fact i didn't get how to use FragmentActivities.
Help! :)
Not sure if you're still looking (hopefully not :) ) but here's a really good one:

Try running ApiDemos app shipped with SDK Samples.

I'm a beginner in Android and I would like to know (and understand) in detail how upgrading an application works.
Thanks.
Google have explained all that right here in the Developer Docs.
