Solution 1:

Perhaps you should take a look at this if you've recently updated SDK tools.

After updating to SDK Tools to rev. 22 for the first time, you may need to relaunch Android SDK Manager again and install a new item: Android SDK Build-tools.

After installing this, clean your projects and rebuild.

Solution 2:

this happened to me after updating the android dev kit and esclipse. couple of things you should try.

if you updated ADT, you must restart ADB server. you probably haven't read the message that says after update. or maybe restart whole pc.

if you're using external jar files, rename the libs folder to lib and revert it back to libs (from eclipse, f2)

Solution 3:

There seems to be a problem with the target build settings within your projects.

The R file will not be autogenerated if there is the slightest error in your project. E.g if you use elements in a layout xml file that are available only in Android 2.2 but your project targets android 2.0. Sometimes the offending elements don't show up as errors because, syntax-wise, they are correct.

I advice you look at your target builds in android manifest.

Or target a higher android build (Get the latest one via SDK manager)
