How do I solve this error in my R.java file. I have cleaned the project and set the resources to UTF-8.
public static final int editText-contact=0x7f050073;
it underlines the "dash"(hi-fen) in red. I have tried to edit it but the logcat stated:
[2014-05-28 15:46:42 - MIPS_HC] R.java was modified manually! Reverting to generated version!
what other ways that i could remove the error??
I got this error when i changed my #+id/RelativeLayout1 to #+id/addnewadmin. I also changed the ids for my individual components like #+id/textview01 to #+id/textview01_firstN.
Is that a wrong move to do because I am still a beginner in android programming. Please help. Thanks.
Read Java naming conventions again. You don't use a hyphen in names.
Simply Replace:
editText-contact
with:
editText_contact
I have an error in my android code..my setContentView is not working.
my code is setContentView(R.layout.secondlayout);
Error is secondlayout cannot be resolved or it is not a feild.
Make sure that you placed the secondlayout.xml file inside res -> layout folder. Also make sure there is no error in this file. If the below line is there in your import statements, remove it.
import android.R;
Try this
import com.example.appname.R
Then, in eclipse go to project>clean , choose your project and press OK. Then wait until it is done. The clean operation regenrates R.
When I add a new activity, add the xml file, and add the palette on the xml file, my R class cannot contain it automatically. Anyone who knows the cause, I beg you let me know, thanks..
R class should be auto generated when the build has succeeded. There can be errors in your xml file which prevents R class to be generated. Check console for errors.
Also check if you have imported it to your class on your class headers. Usually causes errorsif its imported.

I have been following this tutorial, but I have two errors, both "R cannot be resolved to a variable". I have made android apps (easy ones) in the past, and I remember this problem being fixed by checking whether or not I have an import R statement (which I don't) and whether or not the project has been cleaned before being built again (I cleaned it and I still get the error). I am at a loss as to what to do. Thanks!
*I also want to mention I did see the thread of the same title with 170 hits, and the solution of "delete the import R statement" does not apply to my problem (I don't think)
Thanks again
All code is straight from the link above, but here it is for convenience

edit: When I clean the project, I get this message in the Console:

C:\Users\zhong\workspace\eclipse\MyFirstApp\res\menu\activity_my_first.xml:2:
error: Error: No resource found that matches the given name (at
'title' with value '#string/menu_settings').
edit: added a line to layout xml file <string name="menu_settings">Menu Settings</string>
Fixed cleaning project errors, but I still can't run the project from the two R errors.
I'm working my way through the same example, and had the same (or very similar) problem.
Finally I noticed that there was a tiny little red x on the manifest.xml.
Sure enough, it was complaining about this:
android:label="#string/title_activity_hello_world" >
So I added:
<string name="title_activity_hello_world">Hello World</string>
to strings.xml and now it works.
I had the same issue while following the tutorial.
Cleaning the project or cleaning the imports did not solve the problem.
How the problem was (simply) solved : I quit Eclipse and relaunched it.
2 possible things
The package name specified in the Android Manifest isn't the same as the in the Java files.
Or, your IDE hasn't generated the R.java file in the gen/ folder. Try building again (despite the error) and it will usually clear it up.
Basically the R.java file is generated for you and in the same package so you can refer to it as simply R.
I had android:text="#string/button_send"
Which gave the error: No resource found that matches the given name (at 'text' with value '#string/button_send').
I tried to solve the error using the tuturial. But the tutorial fails to tell me to write all the lines required one by one. So I miss to write "<string name="button_send">Send</string>" in the strings.xml.
After adding the previous line the error disappear! Which I believe is something similar to the original problem in this thread.
So if I had copied the whole lines from the given tutorial it may had not happened, but by typing our-self is how I think is the best way of learning.
I found the solution:
go to your project->res->menu than open the XML file there and delete this line:
android:title="#string/menu_settings"
I deleted it and it start to work,after 3 hours of the same warning in the problem section.
It even make sense when you read it, "at title with value #string/menu_settings"
Pleas confirm there is no error in
1- Project folder
2- Problem View of eclipse
3- Console
4- error log as in image
You have to make sure to
Clean your project Project-->Clean
The /res directory doesn't contain errors (some files will show up
with a red icon on the file explorer)
Your imports doesn't contain this line import android.R;
Check that in AndroidManifest.xml, the attribute package has the
correct value. <manifestxmlns:android="http://schemas.android.com/apk/res/android"
package="your.correct.package.name"
This fixed it for me:

Seems like eclipse likes to add an import line to java files for no reason. Go onto your java file, hit ctrl+shift+o and all the import statements will appear. Delete the line that says import andriod.R
Right click on the Project, select "Android Tools" > "Add Support Library" > "Android Support Library, revision 11" > "Install"
In my case, the problem was that I was on 64-bit Linux, and the required 32-bit libraries were not installed, meaning that the build tools could not generate R.java.
Running this command, then cleaning the project, fixed the problem:
sudo apt-get install ia32-libs
Make sure the executables (aapt etc.) in sdk/build-tools/android-xyz/* are executable if you are running the default download on your Linux box...
I had the same error trying to do the first tutorial. To get the app to run I edited MainActivity.java so it looked like this
package com.example.myfirstapp;
import android.app.Activity;
import android.os.Bundle;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
I am getting error in R.java file.
The error is
"The type R is already Defined."
I have tried deleting the R.java and Cleaning the project.
step i have wrote if this situation raise ::
dont delete it, clean it.
goto Windows >>show view >>console and try to solve error?
goto Project >>click -> build automatically
remove import of R from import section
goto layout file and check that is there any id is same name ?if yes then change it
in layout file delete any single space,save and refresh and run.
Reason is that you have checked two Builders that try to generate the same class.
You just have to uncheck the Java-Builder from Project->Properties->Builders.
May be there are two builders for the project.check it in project->properties->builders. I too had the same problem.
Chk this out: Fairtec: Type R is already defined
