Newly created layout files not added to R.java

I have tried literally everything to figure out why no new layout files are being added to my R.java file in eclipse. Nothing is working.

I have:

• Restarted Eclipse
• Used Project>Clean
• Deleted R.java (had to restore because it would not autoregenerate no matter what I did)
开发者_运维知识库
• Ensured all methods are defined in SDK version
• Rebuilt the project
• Unchecked auto-build
• Every combination of above options
• Been tempted to throw my computer across the room

Does anyone have any suggestions?

Check you don't have any errors inside one of your xml files. That is, check not only for xml file name errors but also for errors in the xml code, for example an illegal attribute, a forgotten tag etc. Check this in all your xml files, not just layout files but also anim, xml drawables etc. These errors don't show up in the error log but will prevent the R.java from being generated.

When I experienced the same issue as you this was often the reason. The error highlight was only visible inside the file, not the error log.

Net, go through every xml file with a fine comb.

I faced this kind of problem many times. From my thoughts it is caused due to the problem of images in the drawable or case sensitive of layout file (everything should be small). Check your case sensitive of layout file.

I will give all possible solutions that i had done when something like this happened with me

1. Project-->clean
2. Check for library if there was any for that RightClick-->Properties-->Android-->add
3. Restart Eclipse
4. Check in the manifest for if you have many packages make sure u are using the activity declared package.

I would check the imported R. The problem could be that you have

import android.R;

instead of

import com.myproject.R;

Project -> and check Build Automatically

Is there any error in your resource files? If there is any error in your resource files the R file will not be generated.

When first of u go on Project->Clean the your application then refreshing and auto genrated R.java file for your apps.

Not to be repetitive, but did you check the Android manifest file? The error there doesn't usually pop up.

Did you check for other locale letters (maybe whitespaces too?) in the filenames? Letters that look exactly like Latin. I think I had similar problem with the names. You can try rewriting your files' names.

Project Explorer (Right click on your project) -> Build Project This worked for me.
