No Generated R.Java File in My Project

No generated R.java file in my project

Go to Project and hit Clean. This should, among others, regenerate your R.java file.

Also get rid of any import android.R.* statements and then do the clean up I mentioned.

Apparently Jonas problem was related to incorrect target build settings. His target build was set to Android 2.1 (SDK v7) where his layout XML used Android 2.2 (SDK v8) elements (layout parameter match_parent), due to this there was no way for Eclipse to correctly generate the R.java file which caused all the problems.

R.java file not generated when creating new android project in eclipse and android-studio

Found a solution to my problem. Its the problem with the system 64bit architecture but not with eclipse or android studio. Android SDK is designed for 32bit architecture so i needed to install 32 bit libraries in my 64 bit Ubuntu. Here are the missing libraries

    sudo apt-get install lib32z1

    sudo apt-get install lib32stdcc++6

installing these libraries solved my issue.
Found solution, @Denis Uyeda answer in R.java file not getting generated.

R.java file is not getting created

Some quick solutions to your problem might be,

• use the Ctrl + Shift + O command to "Organize Imports" and generate any missing import statements. Sometimes this would generate the incorrect import statement which would hide the R.java class that is automatically generated when you build.
• R is a generated class. If you are using the Android Development Tools (ADT) it is generated whenever the project is built. You may have 'Build Automatically' turned off. Turn it on and build your project.
• Mistakes in your xml views could cause the R.java not to be generated. Go through your view files and make sure all the xml is right!
• Remove, if any import android.R;
• Restart your IDE.

R.java file is missing/not generated in android studio

This is caused by Android Gradle Plugin generating R class bytecode directly, instead of .java files.

So there isn't any R.java file being generated and if you need information about the R class, you can have a look at the class bytecode by following the steps described in this answer.

R.java file not getting generated

Try this:
I have similar problem R.java not found error it is actually not getting generated

I did almost every thing which are said in the different links in the forum

What I did

1.I delete the project from the workspace and re import it,after doing that when the project launched it start giving me the SDK not found error even I was given the correct Android SDK path.I am using eclispe ADT which you can find from android site itself.

2.I don't know why ADT plugin was showing it needs to update even the latest ADT 21.1 is installed .I tried to updated that then ,i don't know how tools folder from my SDK get deleted after that .It start shouting tools folder not found in SDK folder .So I need to download the SDK again and update the ADT plugin to 21.1 .

3 So I think some time there is problem in ADT plugin ,So keep it update correctly or reinstall it will works if nothing else works .
