Android Studio Edit Configurations doesn't display my app

I want to run my app, but the run button is disabled. When I go in Edit Configurations where I should see "Android Application-->app" I only see the Defaults. Everything was fine 2 hours ago, but I kept working on my project and when I wanted to test it I noticed that I can't. What may have caused this and how do I solve it? I tried to search for a solution, but I couldn't find one.

Close any emulator if open and then reopen your project, maybe it shows.

Can't see errors/warnings in Problems view unless project is selected in Package Explorer

I can not see any errors or warnings in my Eclipse(4.4.2) unless I specifically select the project or file in Package Explorer and then go to the Problem view.
So far I tried different options in "configure contents" and "show" dialogs in the Problems view menu without success. The only time I see errors in the Problems view is if I set the options "show all" or "all errors" and then it shows every issue with every project I have, don't want/need that.
I also tried (following suggestions from other posts) closing/reopening project, Build Automatically and fix project properties... no luck.
I remember it used to be that if you had issues in a file you were currently editing you could jump straight to the Problems view and it would show you the issues for the project where that file lives, in other words the current project being edited. This is the result I want.
Android SDK manager is up to date so I am out of ideas. Appreciate any help.

Open the 'Configure Contents' menu and select the 'All Errors' (click the line don't use click the check box). You should then be able to configure the Scope of the errors on the right hand side of the dialog (such as any element in same project)

Eclipse still runs project by old name

I had a project named "xxx" which I renamed to "yyy". The project works fine on my phone. But Eclipse still says "Launching xxx" when I run the app. How do I remedy the situation? I've tried searching for "xxx" throughout my project, no luck.

I also had this problem on my Android project. Now I found the solution:
Click the down arrow next to the run button.
Select the Run Configurations item in the popup menu.
Expand Android Application and select the item with old project name.
Set the Name: field at right to the new project name.
Click Apply
Hope this can fix your problem.

Go to the launch configurations and have a look at the configuration that´s called xxx.
In the Name field you can edit the name of the launch configuration to whatever you want.
EDIT:
Maybe this documentation article makes it much more clearer:

Eclipse hangs when trying to add menu.xml

I've recently starting developing with the android sdk. Currently, I am trying to add code to use a menu, however, when I try to add a menu.xml under res/menu, Eclipse hangs and freezes every time. When I reopen the Eclipse, menu.xml is there, but every time I try to open it, Eclipse hangs and freezes again.
I am running on OS X Snow Leopard, Eclipse 3.6.2 and the latest android sdk and adt plugin.
Any help, insight, thoughts?? I am thoroughly stuck.
Thanks.

Thanks for the input guys. What ended up working for me was instead of trying to manually create a new menu.xml file, I find the add android .xml wizard and using it instead allowed me to add whatever I needed with out any hang ups.

Same problem happens for me even under the latest version of Eclipse (Helios). If I wait long enough, Eclipse reports a stack overflow exception and then this shows up in the Output window:
W/ResourceType( 5124): Bad XML block: header size 0 or total size 9949440 is larger than data size 0
menu.xml:1: error: Error parsing XML: no element found
This indicates that the XML parser isn't handling empty documents and the Android menu editor is barfing on the newly created file while trying to open it. I'm sure there is some "standard" way of creating a new menu that doesn't break the IDE but I have no idea what that method is. I'm too used to editing my files by hand but this crash/hang bug is a serious nuisance.

Dustin,
I think what has happened is, your settings have become corrupt. I highly recommend resetting all your settings. Keep in mind, you will have to re-import all your projects so this can be quite a pain, but I really think this will fix your problem.
To start, find your workspace folder and rename it to something like "workspace-bad"
Then, create an empty workspace folder to replace the one you just renamed.
Lastly, open eclipse and it will act just like a brand-new installation.
You will need to re-import your projects, which can be done by going to eclipse, hitting File>Import...
Then select under General
"Existing Projects into Workspace"
then hit "Next" and then hit "Browse" to find the root directory
also make sure "Copy project into workspace" is checked
I also recommend doing your "problem project" first, that way you don't waste your time doing the rest and then find out you have to re-create it.
I'm hoping that fixes it for you, good luck! :-)

I ran into the same issue with the same setup. Right clicking menu.xml, selecting 'Open With', and selecting Xml Editor seemed to be a viable workaround for me.

Content Assist not working in Eclipse for Android

I've been working in Eclipse programming for Android for about a year now. I suddenly have an enormous problem. Here is the error:
"Content Assist" did not complete
normally. Please see the log for more
information.
java.lang.NullPointerException
I go to Help>About Eclipse SDK>Installation Details>Configuration>View Error Log and it is nothing but a blank page. No errors at all.
I tried researching online. The most relevant pages I could find are http://forums.adobe.com/thread/455543 and http://www.themorphicgroup.com/blog/2009/10/27/content-assist-did-not-complete-normally/ and http://www.airtightinteractive.com/2010/01/fix-for-flash-builder-content-assist-did-not-complete-normally/ . All of these pages say to close FB, delete the .metadata folder,restart FB, import/export some SWC file, and/or delete some file with "flexbuilder" in it's name. None of these work and I see nothing on my whole machine with any of "Flash Builder", "FB", "flex", or "flexbuilder" in it's name.
As a desperate last resort I deleted all traces of Eclipse, Android, Adobe anything, and Java from my machine.
Absolutely no difference what-so-ever. Besides exhaustion and heartache for me.
The content assist features seem to work fine in java files (for now anyway). It seems that only .xml files are affected.
What can I do to resolve or work around this issue?

Make sure the correct editor is opening the xml files. I have aptana and some other plugins that support xml files. Right click the file in project explorer and select open with, then select Android Xml Editor and see if you have completion.
I dont know if that is the exact name, because my eclipse just went south and wont even open :)

Right clicking the file and opening it specifically with Android Layout Editor is what solved the problem for me. Eclipse will continue to open it up with that editor after choosing that editor.

Uninstalling and re-installing the Android Developement Tools Plugin for eclipse at least partyl fixed the problem for me.
Strangely it worked best when completely uninstalling the plugin!?
