When I attempt to run my Android application I get the following message:
your project contains error(s), please fix them before running your application
All I did was to clean the application and everything went wrong.
Normally, you would see a red asterisk against the offending file and the corresponding line with the error. But in this case I get no such indication.
Screenshots:
Sounds like you have a syntax error in one of your XML files, or an invalid file name.
When you do a clean it deletes certain files, it would then automatically build, if you have syntax errors the R.java file won't be generated and you will have the above error.
you can check in android console(window->show view->console),it will give some more information,check it once,check your build path if your are import your project somewhere else and the project uses 3rd party libraries or you may have problems with your XML resources.
Found the source of my mysterious error.
It turns out it was a imported java class I had forgotten about which I wasn't using and caused the error to showup when I "cleaned" the project.
I visited the build path where I saw it had an associated error. I removed it and all was well.

Based on your answer, I think you should make sure you have every files in your project directories. Try to debug buy going to Analyze --> Inspect Code
and let it run for a while. Any errors will be marked as red. Check it if one of the files have missing references like your case above. More can be found here,

I'm trying to export my game apk for publishing to the store, but then I get an error saying 'compilation issues', how do i fix this?

Follow the Steps :
1.Remove Automatic build selection
2.Clean your project
3.Build the project
4.Export the apk
First fix your project's error then you can export it.
Fix your project code(Make sure that don't present any error) that gives compilation error.
Clean your project
Then export for publish your app..
Well, unsurprisingly this means the compiler runs into problems when compiling the release apk. These errors should appear in either the 'Problems' view or one of the consoles (you may need to switch between them). Finding those will help track the actual problem down.
Also, since you mentioned changing package names you may want to check my answer here: Serializing CDT Project settings has encountered a. I'm fairly certain that changing the package name for my project was what caused Eclipse to corrupt my project configuration back then.
I get the following error in eclipse: r cannot be resolved. However that appeared just after I added my own library as a resource to my project. It seems that eclipse cannot resolve which R to use, the library one or the project one. Note also that the library is marked with the is library check box in the project set-up. Also whenever I remove my library from the reference list eclipse does not show any errors, but upon compiling logCat shows a Class Not Found exception. How do I fix this issue?
Thanks
R is an autogenerated class. If you clean the project, the error should dissapear.
R.java is not getting generated for your project which is done automatically, pls check whether something wrong with any XML file or check console if there is any problem in XML it will show you something related to XML or check something wrong with importing packages. If its not about any XML errors then check on importing that library project in your project. you may get some imports related to something like this: com.android.R then remove this if you see this and then manage imports again.
Whenever I create a new project in Eclipse for some Android application it gives me a red cross sign and on compiling shows following errors:
error generating final archive: java.io.FileNotFoundException: C:\..\bin\resources.ap_ does not exist
Unparsed aapt error(s)! Check the console for output.
On Googling I found that by cleaning the project we can remove this error but it is not working in my case.
Earlier I was able to create Project in Eclipse. All this problem started after installing some Google APIs but I guess they are not cause of problem, something else is there.
Could it be an issue with a command path?
SDK doesnt like being installed in dirs with long names like "Program Files\Google\Android..."
If thats the case, youll need to adjust path appropriately (C:\Progra~2... or smth like this)
