R.java has been manually modified! Return to Generated Version

Question

I added one xml file to the layout. After this, this error occurs. But the problem is that I did not touch the R.java file. Now in my new action I am going to configure the presentation of the contents as my newly created xml file, but when I do R.layout., The Newly created xml does not come up with a sentence. Does anyone have an idea how to fix this. I cleaned the project several times, but it does not work.

Answer 1

Delete R.java and let eclipse restore it and then project -> clean will fix it.

Answer 2

Check if you have any existing errors in your code, if so, fix it and then try updating and creating a project. If your project is created correctly, you will receive a new XML file in the sentence

Answer 3

This happened to one of my Eclipse projects today. This is what mysteriously cemented it. I don’t know why and how.

Changed Properties-> Android-> Purpose of building a project for a higher (different) version of Android and click Apply . Then he made a clean assembly. The problem has disappeared.

After the above steps, I will even go back to the original Project Build Target without having the problem reappear.

Answer 4

May this help you ...

I think your xml file name may have some capital letters or some special characters ..

Delete them, and then try again to start the project.

Answer 5

Try to clean the project, it will do the job.

Answer 6

make sure you don’t import any thing that ends with com.R make sure your layout naming convention is correct.

Answer 7

The R.java file contains all resource identifiers provided to resources (drawings, layouts, styles, etc.) either using Programmer or generated through sdk. So check your xml files as well as your patches. If any of them includes the wrong format, it will show an error in the R.java file, for example, once R.java does not generate, or our class file shows that R.id.xxx is not found or R.class is not defined error.Then clean the project.

Answer 8

There must be an error in one of your xml files. Eclipse does not always show error messages if something is wrong with your xml. Basically, the code gets errors, in this case "R", so you will need to manually go through xml, this may just be a mistake. Good luck.

Answer 9

I had a similar problem. The cleanup project did not resolve the problem and there were no errors in the code or in capital or spaces in the file names.

The solution appeared in a pop-up window that appeared when choosing PROJECT → CLEAN, and then uncheck the box “Start assembly right away”. Clean up the project. Close and restart Eclipse, and then create a project (PROJECT -> BUILD).

The question remains why simple cleaning and assembly without closing Eclipse did not work.

Answer 10

Right click on Project-> Bulid Path-> Configure Build Path ther you see the error android-support-v4.jar, delete this library and add the library again, this works fine for me.

Else Try Go to the gen Folder delete R.java folder, and from the "Project" option, select "Clear Project".

Answer 11

Very late on stage ...

I had this line mysteriously appearing at the beginning of my import:

 import android.R; 

I deleted it and the shazam error disappeared.

Answer 12

I had a similar error, but when I import a new project into my eclipse. and the solution was, I have to check the option (copy the project to the workplace) specifically when there is a library in our project.
