How can I update the available Android APIs in Eclipse (ADT)

I am trying to update my API level choices within eclipse. Currently, the highest I can get to is API 19:
-
I am interested in starting with 5.0 and making that my target API, but I cannot seem to get it as an available option.
I have tried updating eclipse via the help -> check for updates, but have seen nothing new.
Currently, I am using the ADT via eclipse (See picture below)
-
I am sure it is something very simple that I am missing, but can someone tell me where I can find the update to this so that I can start working with things like the glass API, wearables, and Lollipop? Is there a section for updating that I have not seen? Thanks all!

Steps for updating eclipse
1. Download eclipse from the official site
2. Download and install jdk latest version
3. After installing the eclipse , Go to Help > Install New Software.
4. Click Add, in the top-right corner.
5. In the Add Repository dialog that appears, enter "ADT Plugin" for the
Name and the following URL for the Location:
https://dl-ssl.google.com/android/eclipse/
6. Click OK.
7. In the Available Software dialog, select the checkbox next to Developer Tools and click Next.
8. In the next window, you'll see a list of the tools to be downloaded. Click Next.
9.Read and accept the license agreements, then click Finish.
10. If you get a security warning saying that the authenticity or validity of the software can't be established, click OK.
11. When the installation completes, restart Eclipse.
After restarting eclipse , goto android sdk manager .
Now you will see all the android versions and tools

Market Place not working in Eclipse Luna

I have installed Eclipse Luna(4.4) on my system using the binary file and it is having the MPC plugin which is downloaded from the site :
http://download.eclipse.org/mpc/luna/
Still i am unable to find the Market Place in the Help tab, but in the
About Eclipse >> Installation Details >> Installed Software' , 'Marketplace Client' is visible.
Please help me how to Launch it.
Edit- Attaching the screenshot from Eclipse which shows the MarketPlace is installed, still it is not showing in Help Menu

Go to Help/Install new software from the menu, select the Juno update site (http://download.eclipse.org/releases/juno 'try this repository'), and look for the Marketplace client it is in the General Purpose Tools category

Either drag-and-drop the install URL from the Marketplace website to your Eclipse instance (the main toolbar is a good drop target), or open Help/Eclipse Marketplace... to start it. See also the Marketplace documentation.

->open (your eclipse luna folder)-->configuration-->config
->open the config file with wordpad and add the below lines at the end.
org.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient4
->save the config file
->Now restart the eclipse luna and try to access the market place.

Did you try update your Eclipse installation?
I had the same problem and I solved it selecting all updates from:
Help -> Check for Updates
I hope this helps.

Android: Eclipse can't build projects

days ago I opened ADT and it suggested to update 2-3 things. I did without even looking what they were, and after it all gen folders are empty. I have about 40 little projects, and they all don't have R and BuildConfig classes. I can't create a new project, "Compile With: " field stays empty. When I open "Android -> Properties -> Android" then everything is empty there, no Project Build Target and n o Library, and no possibility to add.
I cleaned many times, Built manually and automatically, insatlled Build Tools in SDK Manager. no error in any layout file. what else to do? Help please.

There are two parts to the tools necessary to build an Android project, the version numbers of each part need to match. I suspect that from your description, that you have only updated one, namely the Android SDK Tools
To check the version of this component, click on the Android SDK Manager icon in the toolbar and in the popped up window you will probably see "Android ADK Tools rev 22.6.2" near the top.
Now check the other necessary part, (the plugin), version number by selecting Help, Install new software, click 'what is already installed". At the top you will see the 4 plugin Android components. These need to be version 22.6.2 as well. If they are not then add the repository https://dl-ssl.google.com/android/eclipse and update it if necessary.

In Eclipse , Open Android Sdk Manager and install or update required Android SDK Build-Tools .
Then restart Eclipse .

Goto windows -> preferences -> android -> sdk location and browse your updated sdk and ok.
Hope this will solve your issue

Eclipse has Android SDK manager option Top on left side.
go to Android SDK Manager and Install Android API packages.

I had same problem yesterday and this is how I solved it :
1.Check if your SDK Manager Works if it says that tools folder is missing it means you dont have any SDK installed if you have then go to : Window -> Preferences -> Android -> and browse to find SDK in my case it is ...Documents\ADT\adt-bundle-windows-x86_64-20131030\sdk then click Apply to refresh if it found sdk chose it then do same for your project to make sure it has sdk assigned to use and about R In each class u will have to go to import section and delete R import because eclipse changed it to R.android, then just import your R. class. If that doesn't help please list more information and what you tried so far.
Good luck

Update ADT from 21.0 to 21.1

i downloaded APIs 15,16 and 17. After the download is finished, I closed eclipse but when i open it again it gives me a message box saying I need to update my ADT from 21.0.0 into 21.1 or higher, (and my current project suddenly didnt work, and full of red lines). There is a "Check for Updates" button. But after clicking it, it says there was no update found. I asked Google and found out that there is already ADT 21.1 released. I am wondering if I should just download the latest ADT bundle, but also looking for a quicker solution. I said “quicker” because my internet connection is a bit slow. :( It will take me a whole day to finish the download. :( And also after i downloaded the API, my graphical layouts do not show any more. There is a message saying "Eclipse is loading the SDK. Home.xml will refresh automatically once the process is finished." I waited for eternity, but nothing shows up. Im pretty messed up here. My project does not work anymore, although it worked well before i downloaded the APIs. Can anyone help me?. Thanks.

Go to eclipse > help > Check for updates.
It should list the latest update of adt. If it doesn't work, try this :
go to eclipse > help > Install new software
Click on add
add this url : https://dl-ssl.google.com/android/eclipse/
It will list the updates available- which should ideally be adt 21.1.0 (latest)
install the latest adt and everything should be fine.

The same thing happened to me, here's what I did-
Apparently, the SDK updated to version 21.1, but ADT, still at 21.0. 21.1 is currently a preview release (so I'm not sure how we accidentally updated the sdk...), so you have to manually add the update source. There's a nice guide (http://tools.android.com/preview-channel), but here's what you need:
Start Eclipse, then select Help > Install New Software.
Click the "Add" button, in the top-right corner.
In the Add Repository dialog that appears, enter "ADT Previews" for the Name and the following URL for the Location:
https://dl-ssl.google.com/android/eclipse-preview/
Click OK.
If you have trouble acquiring the plugin, try using "http" in the Location URL, instead of "https" (https is preferred for security reasons).
In the Available Software dialog, select the checkbox next to Developer Tools and click Next.
This worked for me, although I would rather have just downgraded the sdk.
Hope I helped!

go to window -> SDK manager and then install Android SDK Tools to 21.1 and then check for updates again.
I used to get error " update cannot be installed " for that run eclipse in Admin permission.

same with your problem !!!
btw, Thanks for the info ! I tried it after read this and wohooow It worked ! thx
go to eclipse > help > Install new software
click on add
add this url : https://dl-ssl.google.com/android/eclipse/

How to uninstall plugins in Eclipse 3.4.X or higher

The GUI for managing plugins in Eclipse got a bit of an overhaul in version 3.4.0.
This GUI is accessed via the "Software Updates..." option in the Help menu.
The option to remove the selected Mylyn plugin is greyed out. In fact, this is true of virtually every installed plugin. I know that the Mylyn plugins are optional, so why amn't I provided with an option to remove them?

The following text is quoted from the Eclipse help docs:
The Uninstall wizard allows you to review and uninstall items in your configuration. This wizard is shown when you select items and press Uninstall... from the Installed Software page. To uninstall software from your system:
Click Help > About and then click Installation Details... to open a dialog showing pages that provide more detail about your installation.
Click the Installed Software tab to see a list of the software items that you have installed into your system.
Select the items that you wish to uninstall.
Click Uninstall...
The Uninstall Details page will show you a list of the items that will be uninstalled. Expanding each item will show what additional items (if any) will be uninstalled as a result of your choice.
If you change your mind about which items should be uninstalled, you may click Back to see a checkmark list of the items you selected before. You may check and uncheck different items in the list, and click Next when you are ready to continue.
Click Finish to start the uninstall.
Once all of the software is uninstalled successfully, you will be prompted to restart for the Workbench. Click Yes when asked to exit and restart the Workbench for the changes to take effect.

And just to update it for Helios - Eclipse 3.6
Help->Install New Software at the bottom of dialog there is link What is already installed once you click on that you will get list of installed plugins and Uninstal... button

eclipse 3.5(Galieo)
Help>> Install New Software >> Already Installed Plugins >> select Plugins >> Uninstall works charm.

There are distributions of Eclipse that come packaged with certain plugins that can't be mix-and-matched. That is the case with Mylyn, that went from a student's thesis project to an integral part of Eclipse. If you want to actually get rid of Mylyn, you may want to install Eclipse classic instead of the distribution you have, and then install the stuff you need.
The standard Eclipse distributions come with Myln.
BTW, Eclipser 3.5 completely changes all these screens :(

If you are using Windows, make sure you are running Eclipse as administrator. Without administrator privileges, some options may be grayed-out in "Installed Software".

In eclipse Helios (version 3.6), to uninstall a plugin:
Go to Help->Install New Software...
Click on "What is already installed?" link at the bottom right side of the dialog
In the Installed Software tab choose the software you want to uninstall
Click on the "Uninstall..." button at the bottom
Click 'Finish' on the Uninstall Details dialog
Observe the 'Uninstalling Software %' status at the bottom status bar of eclipse
Click 'Restart Now' when prompted to do so.
Eclipse restarts. Choose the workspace. Now when you go again to the Installed Software window , you do not find the uninstalled software.

In Eclipse 3.6 Helios, the interface has changed again. Go to "About Eclipse", and then click the "Installation Details" button in the about box.

While Help → About Eclipse IDE [or wherever it was in the past or will be in the future] → Installation Details → Installed Software → Uninstall... is the official and preferred way there are features/plugins the latter button of which is disabled.
Remember also that there aren't only plugins but features too. In my case I wanted to remove Mylyn and Wild Web Developer from a rather fresh Eclipse IDE for Enterprise Java and Web Developers package. I did the following.
But first a:
DISCLAIMER
Enter ECLIPSE_HOME at your own risk. Mistakes like typos might be in the following, too. I take no responsibility for whatsoever.
Created the directories features.DISABLED and plugins.DISABLED in Eclipse's home dir.
Moved *mylyn* from ECLIPSE_HOME/features to ECLIPSE_HOME/features.DISABLED
Moved *wildwebdeveloper* from ECLIPSE_HOME/features to ECLIPSE_HOME/features.DISABLED
Moved *mylyn* from ECLIPSE_HOME/plugins to ECLIPSE_HOME/plugins.DISABLED
Moved *wildwebdeveloper* from ECLIPSE_HOME/plugins to ECLIPSE_HOME/plugins.DISABLED
After starting Eclipse there were about a dozen "not found" errors in Eclipse's Error Log view. If you double-click on each of them you can see which dependency plugin JAR(s) haven't been found.
Set the Error Log view's filter to just display errors and warnings.
Moved the dependency plugin *.jars mentioned in the errors from ECLIPSE_HOME/plugins.DISABLED back to ECLIPSE_HOME/plugins one by one (with Eclipse restart after each) until no "not found" error appeared in the view any longer. It were nine *mylyn*.jars in the end.:
*.mylyn.commons.core_*
*.mylyn.commons.net_*
*.mylyn.commons.notifications.core_*
*.mylyn.commons.notifications.ui_*
*.mylyn.commons.screenshots.ui_*
*.mylyn.commons.ui_*
*.mylyn.commons.workbench_*
*.mylyn.commons.wikitext.markdown_*
*.mylyn.commons.wikitext.*
Note that this applies to a rather fresh Eclipse 2021-03 (4.19.0) installation. It might be different from one – even patch – version to the other.
Furthermore:
Keep Eclipse's Error Log view open for a while. The underlying OSGi activates bundles (plugins) on the fly if they are referenced from an other bundle (plugin) for the first time. And if one isn't there then...
Check the Error Log view especially after installing new features/plugins. They might rely on plugins/JARs you moved to .DISABLED. If that's the case move the according JAR(s) back to ECLIPSE_HOME/plugins and/or ECLIPSE_HOME/features.
If something doesn't work as it did in the past once in the future remember what you did and ... → Error Log view.

I'm running (a relatively fresh copy of) 3.4.1. I was able to select the same plug-in shown in your screen shot (Mylyn Bridge: Java Development) to get an enabled "Uninstall..." button. I'd suggest getting the latest updates and trying again.

It sure looks like there's no way to do this.
I just had exactly this problem with a fresh download of the Eclipse Java IDE (Ganymede SR2). I didn't want Mylyn, but I didn't want "Eclipse Classic", either, because the download was twice the size, I presume because it includes source.
The apparent solution was to update everything and restart Eclipse, after which the "Uninstall..." button became enabled for the Mylyn plugins. Unfortunately, this only uninstalled the most recent, updated version (3.0.11 IIRC), reverting to the un-uninstallable 3.0.5.

I just don't know what the hell these Eclipse developers are thinking! Removing plug-ins from Eclipse became a pain in the ass since Helios!
I hear you pal... I just went through the whole day trying to figure out as no one seems to give an straight answer like "do this, that, done."
Man I'd rather be programming instead....
Found, in the middle of my evening that it is possible to uninstall pretty much everything. The issue is that the damn thing is hidden in the "HELP->ABOUT". Who would guess after going over and over through the "Help->Install New Software" or "Help->Check for updates" and never finding anything like "remove" or "reinstall" or "force reinstall".
Seriouly, I'd rather go back to 1990 when we had Microsoft, Borland and Watcom.. you picked your platform and you'd be with 1/3 of the world of developers with you.. ok, perhaps Watcom didn't hit that mark but you get the point.
So... to uninstall any plugin from Eclipse Helios (Service Release 1) or Springsource 3.5.2 (or 3.6.1 I 'm using), do this:
close all your projects (just to be on the safe side);
Hit menu "HELP-->ABOUT" (yeah.. help, about);
Hit "Installation Details" button and you get the list with all plugins;
Click on the one you want to remove; hit uninstall;
If want to remove more than one, just apply the change without restart;
Goto to 4) as needed
Finally, restart Eclipse and reinstall what you need !
It was hard to find, but it worked very well for me.
