android - Adt doesn't create default hello world but command line does

Question

My ADT worked correctly as same as whatever saw in tutorial until 2days ago when i created a project like before and also i selected "create a blank activity" and i expect it makes a default hello world project for me and a Main.java also a xml layout file, but it doesn't create this default hello world project anymore. i installed and updated Most of things in SDK Manager. i created another workspace and i did whatever i could but it doesn't create default hello world project. but when i create project from command line it works correctly and make a hello world project. why ADT doesn't do that? it's list of installed package on my SDK manager

and its the project tree in ADT that is empty when i create a project with blank activity:

But it works in commandline. i use same sdk manager from command line:

~/Program/Andr/adt/sdk/tools $ ./android create project --target 24 --name MyFirstApp --path MyFirstApp --activity Main --package com.mrg.myfirstapp
Created project directory: MyFirstApp
....

And it makes Helloworld project:

My OS is linux Mint 15-16bit:

$ uname -a
Linux mrg-samsung 3.8.0-19-generic #30-Ubuntu SMP Wed May 1 16:35:23 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

It's my java version:

$ java -version
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)

and its my ADT version:

Answer 1

This problem was because of New version of SDK and ADT so to update ADT please add this address: https://dl-ssl.google.com/android/eclipse/ ** Be aware it doesn't work with exciting address begin with http so go to Install New software in ADT and do these steps:

Then Select this and press Next and Next and accept licence and press finish to download and install:

Now after restart ADT if you create a project it will work another problem i saw was the AVD doesn't work correctly you can not add new device to solve this problem run this command from SDK path:

~/Program/android/adt/sdk/tools $ ./android avd

After add your device go to ADT and open AVD from eclipse and press Refresh

It should work now
