Can any one let me know how to over come this problem.
Thanks for your time!
Start again and be sure to
have write / read permissions in the folder of your project
avoid special characters when naming things (project/classes/files/etc)

Recently my project got messed up. I don't know how it became like this. There was no power failure or anything happened while using Android Studio. Next day I opened my project and now it's a full mess. I attached the images of how they look now.
Classes are not recognized as you can see they have .java extension showing and when I opened one of them it show like below. but if I opened the file directly from notepad or something the source-code of these files are not changed.
I did delete .idea all .iml files inside the project then invalidate & restart build project again. But no luck, no matter what I did it doesn't get resolved. I have an old backup of this project and not a recent one, so I want to get this fixed .
I tried opening my other projects and they work very well. The problem seems to be only in this project. Android Studio is updated to last version before this problem persisted. So it's not also a bug in Android Studio.
This is how the Java file looks when I opened with Notepad++. The code didn't disappear, no I also didn't write xml code in my Java file:
I just had to copy all the source code in .java files back into android studio editor, which the files are with .java extension. Problem solved
I have same problem occur few days ago, solved by below steps
uninstall android studio,
download latest from link
delete all file from default android studio folder
(C:\Program Files\Android\Android Studio)
install new downloaded android studio , all worked well.
I had a similar problem, but with Kotlin files.
What worked for me was shortening the file name by a few characters (but not the class name).
I suspect that there's a limit to the length of the path which can get quite long if you try to organise a large(ish) project using subfolders.
If you have just created a new package directory inside your project and moved class files from the project into the package directory you just created you will get this error.
To avoid it. Instead of moving class files, copy them and next build your project. Very important this part to build the project.
Next you need to delete the duplicate class files outside the package (Can't use safe delete for this)
And finally you need to change the imports on all affected class files to reflect the new namespace / location. My suggestion is to use "replace in path" from the Menu Edit > Find
Hi i downloaded the vector chat application from this link and i
imported it as a superate project (By using java 1.7 sdk only it was
working).
As a superate project it's working perfectly then i imported (by
copying manually) this project to my personal project then i got some
error, by spending some time i resolved almost all errors but now i'm
getting the error as cannot resolve symbol RoomPreviewData.
This RoomPreviewData class file was generating in the jar file in
vector project (inside of build folder) but in my personal project
it's not generating the RoomPreviewData.
For understanding i'm attaching the images to this question. So, any
one please help me to solve this
Vector project image
Failure project image
Am I getting it right that you're building Matrix SDK artifact by yourself and then importing it into the project? If so, please validate build logs and also see if the file was actually packed into artifact (actually, you may even inspect it as an archive)
Alternatively, you can pull whole package's code from that link and then load it as is into the project
I don't think this was the exact answer, but i'm posting here because it may help others.
I changed the package name of vector project as my personal project (For changing package name fallow these steps)
Imported (Just copy and paste) my personal project into vector project
then everything working fine......
I'm currently developing an Android app. I'm using parse for database. I added parse to the "libs" folder but keep getting the error: "The import parse cannot be resolved". I added the parse .jar file to build path and it seemed to fix that error, however, I'm getting error in run time: "cannot create parseObj subclass".
I would be appreciate it if anybody can help me with this problem
Nowadays putting the JAR in the libs folder should be enough but if for some reasons it does not work for you I suggest you to add the JAR on your classpath when compiling and running.
Right click project
select property
select add external jar
clean, build and run
here is a screenshot:
hello go through below link :-

Here you will get an example with proper code formation....
I recently downloaded the Android Support Package and have been using it trying to get my application, running at SDK 10, to use a GridLayout.
Anyway, I cleaned my project a few times working on this error in my XML files, and then when I went back to my classes in /src, every single reference to R.* was an error.
This has happened to me before, but it usually fixes itself, and it has not yet. Does anyone know what to do?
The R.java file is no longer in my /gen folder.
It sometimes happens when you import another project First i suggest you to build it, it will create automatically .
If it's not working then try to create new project from existing source and specify the downloaded project . It worked for me
Hope this works for you let me know..
Sometimes if there is an error in your XML files R.java won't build. Go through your XML files to make sure that everything is in order (typo, forgetting to close a bracket, etc). When you fix that it should build itself again.
You can also try Adnroid Tools>Fix Project. That may help you to create gen/R.java file
Follow following steps :
In Eclipse,
=> Right Click on Project > Android Tools > Fix Project
By this way, you can fix many common problems which can help generate R.java in gen/R.java file.
There can be several reasons why this occurs. The following I have found happen to me and I have included the steps I took to resolve them.
First step is to try and clean the project (from the Project menu option I believe)
Check there are no errors with your XML files. Sometimes this is obvious from the red 'x' that appears next to an XML filename in the Project exlporer window and sometimes it is not. If it is not obvious check the 'Errors' window (whic is founf in the 'Windows' Menu option
Failing that I have found that by disabling the automatic build option, adding some arbitrary comment to an arbitrary source file, saving the source file, clean the project, remove the comment and then re-selcting automatic build can work too.
Apologies for the approximate locations for some of the Eclipse functions but I am not currently in front of Eclipse to check.
This happens when you have an error in the res folder.
Fix the error first, then do :
Project --> Clean --> Ok
Et voila !
I am trying to do the notepad tutorials and keep getting this error.
I am following all the directions on the website.
I have tried the "Fix Project Properties" via "Android Tools" but this does nothing to fix the problem.
I have put the extracted folder for the tutorial in various locations - this did nothing.
I am trying to create a new Android project from source with 2.1...
I have been told to uninstall Eclipse.
Any help would be appreciated.
Thank you
I was having this problem, and for me it was caused by already having the extracted source code (which I was trying to import into the new project) in the same directory as where I wanted to created the project. So, don't put the extracted files in your eclipse workspace.
This could be (and mainly is for me) caused by some form error in the XML. I would scour your XML and check to verify that you have missed something somewhere.
Try to create New Android Sample Project, select Android 2.1 target and choose NotePad example .
