I've found out that my R.java is never updated, so it doesn't contain information about my new resources, so I decided to delete it and thought that Eclipse would generate a new one. But that didn't happen, and I don't have R.java now. How can I regenerate one?
I'm using Windows 7.
From one of the comments: "Doing Project -> Clean is what caused the problem for me. Cleaning deletes R.java...and for whatever reason the plugin is not regenerating the file."
I found this happening to me with a broken layout and everything blows up. Relax, it's like that old mistake when you first learned programming C where you forget one semicolon and it generates a hundred errors. Many panic, press all the buttons, and makes things worse.
R.
links to is not broken. Fix all errors in your XML files. If anything in the ADKs are broken, R
will not regenerate.import android.R
in your activity, remove it.Menu -> Project -> Build Project
.This usually happens when you have a broken XML file.
/res/
folder/layout/
and /values/
, especially if you've changed one of them recentlyAndroidManifest.xml
. I find that often I change a string and forget to change the string name from AndroidManifest.xml
.Android SDK Build-tools
is installed. Window -> Android SDK Manager -> Tools -> Android SDK Build-toolsAndroid SDK Tools
, you also update the Android SDK Platform-tools
and Android ADK Build-tools
. Build fails silently if they don't match.
