I just updated eclipse and the Android Developer Tools plugin and now when I make a new project and try to run as android application, I get an error: "Your project contains error(s), please fix them before running your application". There is no visual errors (red x on the file name ). I have made several simple projects in the past with success. So I uninstalled eclipse and followed a couple tutorials step by step on setting up an Android developer environment with Eclipse Helios, Ganymede, Indigo with no success.
Does anyone have any idea what the problem could be?
thanks in advance.
EDIT
Thanks for the quick response. I did figure out the problem. Before the problem occurred, I had re-downloaded the android SDK changed the path. But then forgot to install a platform in the new environment.
A common error is that there is a space in the Android toolkit filepath. Make sure it is in a location like "C:/android/android-sdk" rather than something with spaces in it.
Give this a try, and if it doesn't work, please post the actual errors you are receiving.
EDIT:
This has apparently been fixed since r13 of the SDK tools, though it may still be an issue for older versions.

I am using ADT bundle for my Android Application Development
1) From last two days whenever I open my ADT bundle its showing error in all the projects (But I have no errors in my projects and I am sure about it). I tried to clean all the projects but no use... Sometime a restarting eclipse will solve this problem but after few days I am getting this same errors again.
2) Also In my Android SDK Manager some packages like Google API and system images in extras were broken, I don't know what to do.
I tried to clean my projects and to update the SDK manager but nothing solved my problem. Kindly tell a better solution to solve this problem. And tell me why these kind of errors are happening.
Thanks a lot in advance.
But for this kind of problems need more clarifications. Here is my few tips to resolve it. It may or may not work! But better give a try.
In each class or java file which place exactly it showing the error? For example for few it will sow error in R. file and the error will be R cannot be resolved into type. If you are getting this error try to import you package R. file (Like import com.example.R) will resolve issue. If you couldn't import then try to check the package name in manifest file and other layout files. Try to resolve all errors one by one in res folder then clean will help it.
Next check whether Eclipse issue or ADT issue. You said few things are broken in ADT i don't know what exactly it means but try to uninstall and re-install them again.
Try to update eclipse. You can do it by Help->Check for updates
If nothing helps follow the error which are displayed in Problems tab which present near console tab. Otherwise open it here Windows->Show View -> Problems.
Hope anyone will help you if not please follow the errors and edit your question with error. So you might get better answers!
I had the same trouble.
I completely remove Eclipse and SDK bundle; then, i re-install everything.
This worked for me.
Do check this, Lint Error Checking will slow your ADT also seems to be occur error like what you got in a often situation..
so Disable lint from Windows-> Preferences -> Android-> Lint Error Checking, Under
Uncheck the two option in right hand side.
Be aware of what all your projects have JDK compliance.. set common JDK level.. mostly 1.6 based on need change to 1.7 for all projects..
set JDk compliance level in properties of your project -> java compiler and select in right hand side..
Always Check when importing any projects after import if its came up with a compatibility library or external library to be added like appcompat_v7
Check in properties of project under android tab in library section if there is any missing files..
From all the above suggestions are not fulfilled your problem, then go ahead with a new fresh latest ADT Bundle with a fresh download of platforms of SDK.. it will solve most of the ADT problems..
Finally the problem solved
This problem occurred due to missing target SDK in project properties and because of the broken files in SDK manager.
What I did is:
1) I deleted all the broken images and Google api packages from the SDK manager and I re installed all the packages again,
2) Then I selected android 4.2 as the Android Build Target in the project properties.
Thanks all for the time and help.
I was using a .2.x version of Android Studio. Just installed to .3.7 and got two obvious error messages... "Android SDK is not configured for module 'FormerlyWorkingProject' or corrupted" and (when I try to look at any layouts I get) "Rendering Problems- No render target selected." I tried downgrading to .3.2, but no luck.
It seems that some part of my configuration is now missing or messed up. Will someone please give me some guidance on this?
Thank you so much!

From your Project Structure dialog, choose Android SDK under Platform Settings. Make sure it has the path to the right JDK and Android SDK. Correct them, close your project, and reopen.
This is the detailed version of what happened. Please have a little patience and read this. I think my problem is unique.
Initially I had installed Eclipse and followed all procedures and was happily coding my first app. One fine day I fired up the SDK manager and saw the Android Tools had a new update. I tried to install the package. Then may be due to my slow net, something went wrong and Eclipse didn't work at all. It said there was something wrong in some file as an error message.
So I installed Eclipse again and followed all procedures. The address of the workspace and the Android SDK was kept same so that my projects will be automatically imported. But now Eclipse is underlining the R or Resource references in my src files. I do not know what to do.
Did you try opening the sample project that is shipped with andoid SDK? If even that one has the problrm, I think you must update ADT plug-in. Updating SDK and not ADT plug-in caused the problem for me. Once I updated ADT plug-in, everything worked fine.
Though this is a common question . I have searched for almost every topic related to this problem . Did everything people say , but it just didn't work . I disable my firewall , disable antivirus . Run eclipse as administrator , But just cant install . Even I tried offline installation . But I failed . I have tried every possible way .
I tried by using both:
http://dl-ssl.google.com/android/eclipse/
https://dl-ssl.google.com/android/eclipse/
Dont know what to do . It seems I can never try android programming on my PC.
My Eclipse version : Eclipse Classic 4.2.1
Few things:
What errors are you getting?
Someone else had some issues with ADT / Eclipse Classic. Read this post Installing Android ADT plugin v9.0.0 on Eclipse Classic 3.6.1 failed
Is there any reason you can't use Eclipse IDE for Java EE Developers. This will ensure that the java related prereqs are met.
Re-install Eclipse. Might be something wrong with the original install or files missing. (Just saying)
--EDIT--
Are you using JDK 7? Some people have complained that this is a problem with JDK 7, and downgrading to JDK 6 fixed the problem. I would give it a shot if nothing else works.
Are you going through a proxy? I had the same exact issue on my end, and I solved it by correctly entering proxy information.
Today, i tried to update the Android tools i use on Eclipse to version 8.0 and the Android SDK to version 2.3. This caused a loss of adb from tools directory. I managed to retrieve it again and put it back. Then, i searched the forum and found this, that eventually helped me to solved it, by updating the Eclipse first.
So, why is there no warning of proceeding to Android tools update, without updating the Eclipse first, can cause this kind of troubles?
It could have saved some time...
Not to offend anyone, I concur with Niko.
If it was mentioned that Eclipse ADT plugin MUST be updated as adb has been moved - it would have saved some pain.
I have installed these things since Mr Android was born, and I had trouble myself. I go to forums to seek solutions, when I have read the docs and they did not help, and probably whine a bit, coz I'm sure more people are facing this issue. :)
I have a step by step process here:

Thanks,

Please have a look at the docs. The /tools folder has been moved to /platform-tools. You need to add this new location to your (class)path ...
