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

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!

Last night I was fed up with the slow debugging of AVD and somewhere I found about HAXM. Which is basically hardware acceleration support. SO-LINK Shows how to install it for ADT. All went fine until I restarted ADT and then I started to get the error on java.util in one of the OpenCV sdk files. Screen below shows the error.
How do I fix this problem. I hope it had nothing todo with HAXM!
Any help much appreciated!
Go to Project Properties -> Java Build Path -> Libraries.
Remove the Library "Unable to get system library for project".
now select Android from left menu -> tick the appropriate version of android under Project Build Target.
Click on apply and then OK.
Now clean your project.
Right click on project -> Android tools -> Fix Project Properties.
I am using intellij-idea to develop android app. I created a project with an android module, but none of these :
import android.app.Activity;
import android.os.Bundle;
are recognized, I get cannot resolve android symbol. I googled this issue but none of the remarks I found there seems to debugg my problem
What you should do is,
1. Select your android project
2. press ctrl +alt + shift + S
3. Select SDK from the project settings
4. Check the files under the class path tab
5. There must be android.jar ,res ,annotations.jar
Probably there should be missed one or several files in step 5.
Then,
6. Go to Android SDK home path field and add your SDK folder again
files even though you have all the jars and still you are getting the error ,then remove all the jars from the class path and add them again ( like in step 6).
7. Build menu -Rebuild your project.
Now your errors should disappear.
i have the answer guys
1- press ctrl+alt+shift+s
2-in the Modules bar click on your project name
3-change the compile sdk version to the newest one
4-click apply and ok then sync your project
5-done , i hope the best for you
Basically, this is because you didn't add Android SDK.
So you need to add android SDK.
go to Files and select project structure.
go to project and select the project SDK
click New and select Android SDK version
If you download android SDK now, it comes with a custom eclipse with android fully installed on it, so way easier
Solved!, it was solved by downloading Eclipse Indigo, but as indicated online, they tell you to go to ‘File>New>Other…>Android>Android Project‘, but Android Project is not in the list?
So,
I recently wanted to start making a Java android app, and by going to developer.android.com, they told me, install Android SDK tools, so i did that, then in eclipse, i have to got to help, ad new software, and use this : Enter Android Development Tools in the Name field, and https://dl-ssl.google.com/android/eclipse/ in the Location field. , so i did that, and it keeps giving me this error :
(com.android.ide.eclipse.adt.feature.group 20.0.2.v201207191942-407447)
Missing requirement: Android Development Tools 20.0.2.v201207191942-407447 (com.android.ide.eclipse.adt.feature.group 20.0.2.v201207191942-407447) requires 'org.eclipse.core.runtime 3.6.0' but it could not be found
i looked it up on google, but couldnt find anything...
Does anyone now how to fix this?

Try using the latest version of Eclipse (Juno), or at least Eclipse Indigo. The newer version of the Android Framework might have dependencies that the latest versions of Eclipse provide.
If this is incorrect / doesn't work, let us know so we can update the solution.
You didn't install ADT plugins yet or something goes wrong.
Download ADT-20 form HERE
In eclipse goto--> Help --> Install new Software --> Select ADT-20.zip
For step-by-step instruction HOW TO INSTALL ANDROID see this
As per your given error it is sure an version problem.. you might be trying to add ADT whose version is below ADT-20 and your ecllips is asking for ADT-20..so try to provide link which contains ADT version 20. If still problem exists go to : http://developer.android.com/sdk/installing/installing-adt.html there they have also given download for ADT-20.zip file download it and install it manually.
I had the same problem, I installed Eclipse Indigo and it worked perfect... because it's version 3.7.2 so it should be working fine with this.
I'm using Eclipse to learn to develop Android applications in Java. I haven't used Eclipse before.
The project I'm trying to use (supplied by OReilly as part of 'Android Application Development') is MJAndroid. When attempting to run the project, the Run fails, and the Problems tab mentions com.java.Object can't be found, and Eclipse asks me to check the build path. Clicking
Properties -> Java Build Path -> Libraries, the message 'Unable to get system library for the project' is displayed.
On a working project, Properties -> Java Build Path -> Libraries has an entry for Android 1.1, which if I click Edit, has the classpath container path of com.android.ide.eclipse.adt.ANDROID_FRAMEWORK.
It seems a simple matter of adding the correct container path to my non-working project. However Eclipse seems determined to make this as difficult as possible. No matter what I chose to add - jars, externals jars, variables, libraries, class folders, external class folders, nothing seems to take the form of 'com.android.ide.eclipse.adt.ANDROID_FRAMEWORK' that the 'Android 1.1' entry on the working app has.
How can I add this namespace to my project so it resembles the working one?
I'm quite sure it's a problem with Eclipse's somewhat odd user interface. Frankly there' nothing I'd prefer more than a file to modify and set such information - my background is in Python, and the whole eclipse environment seems an unnecessary burden.
I had faced the same issue when I imported a sample code downloaded from the internet. I am using android sdk 1.5 with 0.9 ADT plugins. Here is a simpler way to fix the andoid library reference issues
Right click on the project which has
issues and select properties
Select the appropriate Android build
(1.1, 1.5 or 1.5 with google api) and
say ok
Again right click on the project and
select "Android Tools > Fix Project
Properties"
Fix the imports once (if required)
Refresh the project and you should be
ready to go without any manual
editing
I faced this same problem after importing a project through GIT. The problem was that I didn't have the same target android platform installed, and the build path somehow got corrupted.
The first obvious thing i did was changing the target sdk in the project.properties, but even after cleaning up the project and Android Tools > Fix Project Properties, it didn't help and I was still getting the build error.
My solution after wasting close to 1 hour trying to figure this out?
RESTART ECLIPSE
Everything worked fine after that. Eclipse is pretty fickle. Only through years of experience you'll then understand her well. :)
Had the same problem and it turns out the Android SDK Location was not set which was a really simple fix. Go to Window->Preferences, click on 'Android' on the left hand menu, fill in the location of the Android SDK (e.g. C:\Program Files\Android\android-sdk) and click OK. Everything worked fine for me after that.
Found the answer in this set up guide: http://developer.motorola.com/docstools/library/Installing-Android-Dev-Environment/
Sometimes Eclipse can get a bit funny (technical term) with classpath container resolution.
You have a working project in your workspace, so you can rule out plugin installation issues. You could try opening the .classpath file (hidden by default, select the triangle in the top-right of the Package Explorer view, select Filters... and uncheck .* resources) and manually adding the container declaration.
`<classpathentry kind="con" path="com.android.ide.eclipse.adt.ANDROID_FRAMEWORK"/>`
You may then have to close the project and open it again (right-click->Close Project) before Eclipse recognises the change.
You may also find that there is an Android builder and/or nature. If you compare the .project files for the working and non-working versions you may see entries for Android builders/natures. Copying the relevant entries may resolve the issue.
sometimes, eclipse can help you.
In Android projects, click right button on the project-> Android Tools -> Fix Project Properties.
It's usefull in class path errors!!
Luck!
I would verify you have the correct version of Java installed as well as the Android SDK. I would recommend installing/reinstalling the ADT plugin in your eclipse, makes it alot easier to create the android project.
http://developer.android.com/sdk/1.5_r2/installing.html
Also. I guess the path of the Android SDK must be setup correctly. This happened when I was overloaded with projects and I decided to create a new workspace copying some existing stuff into it.
Seems that the new workspace requires you to setup these details too once again
Is that setup properly?
