After making a series of edits to a previously working android project in eclipse, I attempted to run the app and got a message "Your project contains errors, please fix them before running your application." Normally under these circumstances there are either some red marks next to the offending file(s), and/or text descriptions of errors listed in eclipse's "Problems" tab. But this time there are no red marks to be seen anywhere, and the errors I see described in the "problems" tab refer to files that (as far as I can tell) have nothing to do with my project.
I noticed that at the top of my list of problems it says "Errors (100 of 192 items)... I am wondering if perhaps I am being shown 100 problems from other projects (I have many on the go at the same time) and my critical error is one of the 92 remaining which I'm not being shown... I'm stuck as to how to proceed.
Close the projects you don't care about and do a clean build.

The wise ones suggest dramatic solutions. Is there any harm happening? can I hope that it will recover all by itself. Is this a "cloud no bigger than a man's hand" coming to engulf my project in a terrible storm?
There are 3 cases that i can think about :
1)You have got some kind or warning for example :
Lets say that you are using google maps and want to add "current location button" - if you wont check if the user accepted location permission or not you will be able to run your app but you will have a warning in red line.
2)If some view is marked in red but everything compile with no errors , this is some error and cleaning and rebuilding your project should fix this
3)If some file name is marked as red , there may be some error/warning inside that file itself(for example - XML error inside some layout that allow yo to compile your app)
#user462990 If you can't see any obvious issues. I'd suggest the static analyzer Lint tool. It inspects your code and would give you a detailed report of all issues wrong with your project.
Just go to Analyze->Inspect Code.
In the Specify Inspection Scope dialog that appears select Whole project.
Lint inspects your code without building it and gives you a report of all the issues in the Inspection Result tool window at the bottom.
Clicking on any of those issues takes you to the editor at the exact line of code where the issue occurred.
See below captain Lint reporting for duty 💪.
What's the problem...
It's the color of the "R" now it's red, it was . always black before.
I compressed the project and re-opened it again and the viewPager which was red is now black.
As the title says, I m having problems with eclipse every now and then. To list few,
Missing R (the most frequent issue)
Conversion to Dalvik format failed with error 1
Cannot find resource
etc..
I tried many solutions already on SO, this and this and this as well. However the issue still persisted.
I checked and ensure that there was no issue with the xml. I must have cleaned my projects more than n number of times. But the only thing that helped (and is now what I have started doing frequently when any of these errors pop up) is restarting Eclipse. Sometime the error goes in one restart, sometimes two.
Even though this restarting has helped me most of the time (almost all), it is at times very frustrating as I loose good amount of time because of it. So I want help to find some solution here.
Note: My Eclipse says version (Android DDMS - 22.6.2.v201403212031-1085508). Also this has occurred for different projects so I do not think that this should be code specific (I may b dumb for this point). (Also the log cat doesn't point to any specific part of the Projects apart from a red highligt error)
I'm using Eclipse for programming on Eclipse. Few days ago, I have installed many features of Enterprise Edition of Eclipse. When I program on Android and use Android Layout Editor again, I meet many strange thing:
1) I cannot reiceive error/warning. For example, when you use: android:text="stackoverflow", Eclipse will warnning: use should use String resource at Left panel (maybe x or !). But, I cannot see it now :(
#: hightlight as you see on StackOverFlow, but instead blue, it's red :D
2) Instead of warning/error, I will hightlight red at that line. for example: android:text="stackoverflow". And it's very difficult to me to follow.
I think maybe some config change, but when go to Windows\preference\android\Editor: I still cannot see any categories can fix it.
Please help me.
thanks :)
I'm not quite sure what you mean, but I'm assuming that you are no longer seeing warnings or error notifications in the XML editor. Check your settings at Window -> Preferences -> Android -> Lint Error Checking. Some error messages might have been set to Ignore. Any warnings or errors you want to see, you should set to either Error or Warning.
Take a look at Warnings in xml resources. This might point you in the right direction and give you visual cues.
I need help...I don't have much hair left to pull out.
I use Eclipse and I use the "Project Explorer"...
I am no longer able to launch my app. It now tells me it is having errors but not marking anything with a red X other than title. It calculates up to Launching App name 100% then says there are errors. any time I change anything and save it the x on the disappears, so I attempt to run it and comes back with the red X and error that there are errors, but I have no clue. I even deleted everything I added to put it back to the last launchable version and even that isn't working.
I have no clue how to read the log cat or the error log.
I tried cleaning the project but the same thing as above happens.
This makes no sense...there is even an R.java file. I have no clue where to even look for an error or how to find it...
Please help...I'm sure this something simple that I am overlooking.
Do you have the Problems view open and visible? It will list all build/compile errors.
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.
