    android eclipse eclipse-plugin adt r.java-file
    After upgrading to Android ADT version 22 and cleaning my project, the R.java files went missing. I can’t use setViewContent(R.layout.activity_main) because the activity cannot reference to the xml layout (due to the missing R.java). Also, when using the (ctrl + space) to get suggestions for setContentView, the code is not typed in. Upon looking at the error log, it shows that there was an “Unhandled event loop exception”. The plug-in involved is the org.eclipse.ui.Also, whenever I create a new

    java android netbeans r.java-file
    I’m doing this for a project in AP Computer Science.Basics: Mac OS X 10.5.8 NetBeans 7.0 Android SDK 3.0 (Level 11)So I’m trying out some of the Android API Demos in NetBeans (I prefer it over Eclipse) and I’m using samples\android-11\ApiDemos\ for the source.
