So I've been working on projects for my class and I had a small error in an extra instance I was calling. I hit clean to see if it would clear it out and instead it created errors on all of my buttons and all of my toasts. It now says they all cannot be resolved or are not fields. They were all working fine until I had hit clean as I had tested everything right before doing so. Has anyone else had this occur?
I know it sounds weird, but this occurs when there is an error in one of the .XML layouts, no matter Eclipse is not detecting it. Please check any recent changes in XMLs and clean again.

This is the image of my main_avtivity:
This is the image of my activity_main.xml layout:
I have imported com.example.calculator.R class. I even tried to clean the project so many times. I even made a new Project two times. Moreover my ADT Plugin is properly installed. Plz help me. I have done everything mentioned in other StackOverflow answers but nothing seems to be working for me.
R.java won't generate properly if there are errors in your XML files. So look through your XML files and look for any possible issues. The errors in the console at the bottom of your second screenshot would be a good place to start.
First SaveAll your changes then go to project>Clean Project and Build it again. Its seems like you didn't save your project.
I know this is a rare question. Even if there are people using MyEclipse for Android development is doubted :(
The annoying thing is that after I modified my Android project (like an Activity class of a xml file), the project remained the same as it was when I imported it.
I thought there is an important feature that demonstrates this error: When I run my Android project and the console reported that "Activity not started, its current task has been brought to the front". This line occurs because the project didnt changed while as a matter of fact I did change the project and saved it.
Is there anyone has the same problem like me?

This was what I did: first, I modified one of my activities by commenting out the Toast functions; and then, I ran it however the Toast line still showed on my Genymotion emulator
Every time I open an activity layout in order to view its design, I can't see anything, and there's a "Loading configuration" message. How to solve it?
Looks like this is related to the following issue: https://code.google.com/p/android/issues/detail?id=56691&q=%22Loading%20Configuration%22&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars
I had the same issue and it got solved by using the menu item: File->Invalidate Caches/Restart
Try to delete the build folder.
Here are the details:
Yesterday(2015/6/10) I faced to the same problem, and I solved it by using beyond compare:
This problem occured after a forced upgrade.
I have 2 projects, one worked(newly created) and one doesn't.
So I used beyond compare to compare the 2 projects' folders.
Luckily I found build folder of the not-worked never changed even though I clear cache, restart and rebuild it several times.
build folder deleted and everything worked fine now.
I've had this issue before, and it was usually not long after an error had come up.
Check the Event Log for errors. Usually a restart of the IDE fixed it for me though I appreciate that's not ideal. The errors weren't anything specific I think just teething issues with Android Studio - tis just preview software after all.
I'm android developer and I use Eclipse.
Sometimes, when I am debugging my apps, Eclipse doesn't stop on my breakpoints. Eclipse shows a "v" symbol on the breakpoint. I think this symbol means that Eclipse has passed the breakpoint without problems, but I would like Eclipse to stop when it reaches the breakpoint.
Of course, I have pressed the debug button (the icon with the green bug on it.)
How can I avoid this behavior?
Most likley your source and class files run out of sync. If this happens clean and rebuild your project. This should make the issue disappear.
solved, it's because i have that activity in another process in the manifest... wow
Old post - but pulled my hair out for a few hours with intermittent trace/breakpoints, so this may help someone.
The solution for me was simply to use the --clean flag to start Eclipse, so ./eclipse --clean
I'm having a troubling problem testing some code for and Android app. My app has two parts, and activity where the user changes some settings, and a broadcast receiver that responds to SMS messages, both in the same package.
Here's the problem, I first implemented some simple code to test out the broadcast receiver and the activity, and both worked fine. But then as I tried to refine the code, I noticed the emulator wasn't picking up any of my changes. Event went so far as to uninstall the app from the emulator and try again, no luck. Then I added some extra Toast popups to my receiver, nothing, still running the old code. I know its running the old code because its sending out an SMS using a string constant that is no longer in the current code, so it should be impossible that it respond with that value.
Here's the kicker that has me confused. For fun I made a change to my activity. Ran the project from Eclipse and that change showed up! Tried to test the receiver code again, runs the old code that doesn't even exist anymore!!
How in the world can half the package update, and the other half not?
Can anyone help me out 'cause I'm about ready to lose my mind.
I had a similar problem. Changes made to classes imported from another project didn't get picked up by eclipse, but those made to classes in the current android project were.
Making a change to the current android project (inserting a blank line and deleting it) seemed to make eclipse pick up all the changes made and upload the app to the emulator.
I had this problem too, Now I found a working solution. Just follow these steps:
Run your project normally.
When emulator started, run your project again (DO NOT close the first emulator)
Then the updated application will be uploaded into emulator
I can't really be sure what happened but creating an new emulator image appeared to solve the issue.
I don't know why it happens but it's a problem I have all the time.
What I typically do is
Close the emulator
Close Eclipse
Reopen Eclipse
Clean the projects (in Eclipse, select Project -> Clean... -> Clean all projects)
Rerun the emulator
Annoying as hell but seems to work for me.
I'm having this problem too. It mostly happens when errors are entered into the code. The strange thing is if I go back to the original code, Eclipse doesn't revert to the original code. One thing that seems to help is to temporary delete the contents of a file, save, and rebuild, and then enter the contents back into the file, save, and rebuild.
How is one supposed to debug in such an environment?
