eclipse - starting with android sdk

I want start programming for android..
What I have:
-Windows 7
-Eclipse Classic 4.2
-Downloaded all there required files - http://developer.android.com/sdk/installing/adding-packages.html
-ADT Plugin
I want install new ADT plugin.. at first I tried to download it from http://dl-ssl.google.com/android/eclipse, I add it, but if i selected it there is only "pending.." and nothing has load..(maybe internet connection?I have selected Native connection in preferences
after pending it wrotes:
Unable to connect to repository http://dl-ssl.google.com/android/eclipse/content.xml org.eclipse.equinox.p2.core.ProvidesException
)
Thats why I download ADT plugin.
So if I select downloaded ADT plugin - content of it load - developer tools and ndk plugin so I select all and click next.
It loads and writes this:
"Cannot complete the install because one or more required items could
not be found. Software being installed: Android Development Tools
20.0.3.v201208082019-427395 (com.android.ide.eclipse.adt.feature.group 20.0.3.v201208082019-427395) Missing requirement: Android Development Tools 20.0.3.v201208082019-427395
(com.android.ide.eclipse.adt.feature.group
20.0.3.v201208082019-427395) requires 'org.eclipse.wst.sse.core 0.0.0' but it could not be found"
requires 'org.eclipse.wst.sse.core 0.0.0 this problem is shown here:
http://developer.android.com/resources/faq/troubleshooting.html#installeclipsecomponents
but there is solution only for version 3.3 and 3.4 (I have 4.2) anyway
but I tried it- I look for updates but nothing were found
I really dont know where could be problem..
Thanks for any answer.
(sorry for my english)
I will send 1€ to somebody who can solve my problem ;) (I think all problems all for internet connection but I cant set it..)

check this
ADT requires 'org.eclipse.wst.sse.core 0.0.0' but it could not be found

As described in solution here u need to add repository address for updating Eclipse as well because ADT plugin requires some of Eclipse components which might not exist in version u downloaded :)
Links for updating Juno Eclipse is http://download.eclipse.org/releases/juno
Be sure that "Contact all update sites during install.." option is checked..

Try the following:
1) Run eclipse as administrator
2) Make sure you have the following urls included as "Available Software Sites"
(a) for Eclipse juno, "http://download.eclipse.org/releases/juno/"
(b) "http://download.eclipse.org/eclipse/updates/4.2"
(c) "https://dl-ssl.google.com/android/eclipse/"
Hope this helps.

Unable to install ADT in eclipse Juno

I am getting error:
Cannot complete the install because one or more required items could not be found.
Software being installed: Android Native Development Tools 20.0.3.v201208082019-427395 (com.android.ide.eclipse.ndk.feature.group 20.0.3.v201208082019-427395)

Windows 7 Professional 64Bit.
Eclipse Java EE IDE for Web Developers.(32 Bit).
I wanted to install this only through Offline. Because i wanted to send it to my friend.
No issues on Android SDK.
I have Tried the solution by enabling only http://download.eclipse.org/releases/juno
and https://dl-ssl.google.com/android/eclipse/ remaining its disabled.

Deselect the Native Development Toolkit in your installation selection in Eclipse. You don't want that. It is for writing C code used in Android applications and it is absolutely not needed for Android beginners or to write a normal Android application.

Ensure you check the box 'contact all update sites during install to find required software'. This prevented my default juno 64bit install from adding ADT. I'm not sure how you would identify the sites used for the additional dependent libraries being pulled in for your friend though.

I had a the same problem but with a different package. Starting Eclipse as an admin solved it for me

Android plugin install Error. operation cannot be completed

I am trying to add plugin android ADT for eclipse.
I've followed the steps given here
But when I am trying to install available softwares its giving error like
"The Operation cannot be completed. see the details."
in the details the following error is getting displayed.
Cannot complete the install because one or more required items could not be found.
Software being installed: Android Development Tools 16.0.1.v201112150204-238534 (com.android.ide.eclipse.adt.feature.group 16.0.1.v201112150204-238534)
Missing requirement: Android Development Tools 16.0.1.v201112150204-238534 (com.android.ide.eclipse.adt.feature.group 16.0.1.v201112150204-238534) requires 'org.eclipse.core.runtime 3.6.0' but it could not be found.
I am getting same error even if I downloaded the ADT-16.0.1.zip and given the local archive path.
I am using Eclipse Gelelio.

The problem is that you use an old version of Eclipse (Galileo) 3.5.x. There is a requirement in Android SDK that you should use Eclipse 3.6 minimum (Helios). So you have to install at first new version of Eclipse.
I faced with the same problem when I was using Ubuntu 10.04 because by default from the repository it installs Eclipse Galileo.

You are facing an Eclipse bug/issue. You need to following workaround (also mentioned here)
Select Help > Install New Software... Click the link for Available> Software Sites.
Ensure there is an update site named Galileo. If this is not present, click Add
Enter http://download.eclipse.org/releases/galileo for the Location
Now go through the installation steps, Eclipse should download and install the plugin's dependencies.

Android ADT Installation Error

I'm using Ubuntu 11.10 and installed Eclipse from the Ubuntu Software Center. Here's the information of the Eclipse I've downloaded. I have Java SDK 6 and 7, but Eclipse is configured to use the Java SDK 6.
Version: 3.7.0
Build id: I20110613-1736
I was about to install the ADT plug-in on Eclipse when after hitting the first Next button in the installation these error telling me I can't install the ADT unless:
Cannot complete the install because one or more required items could not be found.
Software being installed: Android Development Tools 16.0.1.v201112150204-238534 (com.android.ide.eclipse.adt.feature.group 16.0.1.v201112150204-238534)
Missing requirement: Android Development Tools 16.0.1.v201112150204-238534 (com.android.ide.eclipse.adt.feature.group 16.0.1.v201112150204-238534) requires 'org.eclipse.wst.sse.core 0.0.0' but it could not be found
How can I resolve this problem?
Thanks in advance.

The first recommendation is to NOT install Eclipse from any Linux package manager or software repository. Instead, just get it from http://www.eclipse.org/downloads/. The builds that linux distro's install are often modified (mangled, some would say).
The particular error you're getting is because ADT requires part of the Eclipse WST project features, but the update sites you have configured don't include WST. Getting one of the packages directly from http://www.eclipse.org/downloads/ will solve that, along with knowing exactly what you've got (as opposed to relying on whoever assembled the package for Ubuntu).

I had similar problems and the above answer did not work, in this case try:
deleting workspace directory
check running eclipse as root (just for duration of this ADT install)

'required items could not be found' error when installing ADT plugin

Cannot complete the install because one or more required items could not be found.

Some info:
Eclipse SDK Version: 3.6.2
jdk-6u26-windows-i586
Windows 7
Any suggestions on how to solve this 'required items could not be found' error?

Have had the same problem a few times. You need to add the following urls to the "Available Software Sites" of your eclipse installation:
http://download.eclipse.org/releases/indigo
http://download.eclipse.org/eclipse/updates/3.7
That should fix it.
If not, see my install paths, and add as needed:
Also, make sure you tick the box on install that says "Contact all update sites during install to find required software".

Use the Android Bundle
