I renamed a project in Eclipse via 'Refactor > Rename' as suggested in this answer.
I now want to rename it again, but the Refactor menu has only one menu item now (Android > Extract Android String...) which is also greyed out!
I am using Eclipse 3.6.1 with the latest Android SDK 9.
Why is that and how to I restore this to normal?
Update (1): After following Sankar Ganesh's suggestion (selecting a string), the Refactor menu appeared again. I then selected the Rename... menu item again and I received the following error message box:
This is much better than the previous situation, in which I had no idea why the Refactor menu had been disabled and what to do. Still, I don't understand why this is and what rules I should follow when using the Refactor function. I only wanted to rename a project... that's all. :)
Update (2): I just tried the same exact operation again again (Refactor > Rename while the project is selected in Project Explorer) and it worked! (without issuing the message box shown above).
What's going on?
Must be a bug, because this is clearly inconsistent.
I was wonder,why you struggling for Renaming a project,
if you want to rename your project, then simply you can select your project, then click refactor menu, then Rename, that's it
step1:
Step2: Now see My project name is updated,initally it was friend finder, now friendfinderupdated
Also , you can use Extract Android String for Valid Java Identifiers and not for packages and files, because see window here
Pls select a String in your java code and do that Refactor -> Android -> Extract Android String, now you can see dialog, what i had shown below
and see next image
Mystery solved!
The problem turned out to be that I was trying to 'Refactor > Rename' while in the Resource perspective.
Once I switched to the Java perspective, this (inconsistent) behavior didn't repeat itself and I was even able to check the Update references checkbox.
Wow!
(thanks #Sankar Ganesh for posting the snapshots, because that allowed me to notice that there is an "Update references" checkbox and that the text on your caption bar is different than mine)

I was targeting SDK version 21 or 22 in one or my old projects.But now I have updated to the latest SDK version. Now I can see a lot of redundant casts of views (As view casts are redundant now). Is there any alternate to remove all those redundant casts at once Via any short cut way rather going through each and every file and remove? I am using Android Studio version 3.2 now.
Pressing ctrl+shft+A will open action dialog. In it type clean in and from suggestion list select Code Cleanup. This will open a separate dialog from which you can select your relative scope. Select which option suits your need and press OK.
Right click on directory which you want clean up.
Select Analyze > Code Cleanup
Click OK.
Here you go!
Select Your Project folder or app (according to your project explorer view)
Select Analyze from menubar
choose option Code cleanup or silent code cleanup .
Where Code cleanup prompt you dialog with options like Project or module and silent code cleanup cleanup without displaying the Code Cleanup dialog. from currently selected project or module.
One of the most useful functions in AS is right-click and 'Find Useage' or 'See Declaration'. For my code, the 'Find Useage' will show all instances of where a function/object is used.
I have the SDK source code in AS too, but I can't 'Find Useage' on that code. Is there a way to set up my projects so that I can use 'Find Useage' on Android SDK code? For example, I would like to go to android/platform /frameworks/.../Configuration.java, right click on Configuration, and see where that class is being used elsewhere.
Failing that, is there a way to find useages short of grepping around the massive SDK project?
Yes, that is possible. You can configure the scope of the search function.
Move the cursor on the symbol you want to analyse, press Ctrl+Shift+a (search for action) and search for Find Usage Setting or from the menu select Edit -> Find -> Find Usage Setting and select Project and Libraries in the scope section.
If the menu item is grayed out, it's because no symbol has been selected.
Furthermore, if you are looking for a particular feature in AS the search for action function is a huge time saver.
BTW: If Project and Libraries is not available it's because there is no usage of the selected symbol in any library.
May be you are looking for this:
Edit->Find->Find in path...
If you are using Android Platforms Codebase directly from the repo, then you can do it. In this case, you will have to update your dependencies by creating another gradle project in your studio where the platform codebase is and then import that in your project.
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)
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:

I'm just getting started with eclipse and android development. One thing which is driving me crazy in eclipse is the problems panel with error/warning messages. It displays errors and warning from every project that I have added to eclipse. I only want to see feedback from the project (or ideally individual file) that I am currently working on).
For example, I have two android projects added to my eclipse workspace: HelloAndroid (a sample app) and SMSTest (an SMS2Toast example). Even with no files open, I see warning messages from both projects! Why is this!?! I shouldn't see any output unless I actually have a file open...or is this just the way eclipse works? Should I be using a different workspace for each project?
Thanks for any help anyone can give me.
This will get mostly what you want:
Open the "Problems" view (Shift-Alt-X-Q)
In the right hand corner there is a drop down arrow
Select "Configure contents"
Then pay attention to the "Scope" options
I also highly recommend in that same menu "Group by" -> Java problem type.
Right-click the unwanted projects and click "Close Project" you shouldn't get notifications from them at that point.
Other than that I'd recommend fixing most errors before moving away from them. If you're not prepared to complete various functions at any given time just put a stub in them that satisfies conditions with a quick //TODO: statement telling you to fix it later.
If you're talking about working on a page in general and the errors are combersome and annoying then try double-clicking on the tab for the file you're coding (above the code window) and it should become "fullscreen" hiding the other portions of eclipse.
As far as I know, this is the way eclipse works. It makes sense in that if you make a change in one file, and it causes a compilation error in another file that you don't have open you would still want to know about it.
You CAN configure which situations are considered WARN, and which are IGNORE in Preferences > Java > Compiler > Errors/Warnings.
Also, if you only want warnings from one project you can CLOSE the other project, which would keep you from having to reconfigure a new workspace for each.
