问题 I see a lot a similar questions R.java can't compile , No resource found that matches @android:style/ "just after SDK & ADT update" leading to existing projects can't compile The R.java file cannot be compiled. I find out the errors come from referencing <style name="Theme.Wallpaper" parent="android:style/Theme.Wallpaper" > <item name="android:colorForeground">#fff</item> </style> What is happening is that some styles, like Theme.Wallpaper are not public. You should not extend from them

问题 I am working on a little Android Studio (version 2.2.3) application. After adding a second activity with a lot of components I noticed that when I type R.id in the first activity, the auto-completion proposes me the components from the second activity. Is this normal ? And here is a working example of my issue (I took the screenshot from it), for simplicity I just created two empty activities each one with a button. AndroidManifest.xml : <?xml version="1.0" encoding="utf-8"?> <manifest xmlns

问题 I googled a lot to find various hints what could cause this problem. Many of them on this forum, but nothing works. I installed the sdk from scratch on 3 different machines (xp, macos snow leopard, leopard) and always the same problem, that even the sample code in the android sdk doesn't compile.

问题 I made an error in an Android layout file (forgot the dp in my dimension), and upon rebuilding, Android Studio replaced all of my references to R.java (which, because of the erroneous build, did not generate) with android.R.java . Is this normal behavior? How do I disable this?
