How to see content of built-in android.jar

Issue

Is there anyway to see res/drawable/... files? when I click on .png files it says: "System editor can only open file base resources"

Find them in your Android SDK directory, then open them in your favorite image editing program. You can find them in $SDK/platforms/$API/data/res/, where $SDK is wherever you installed your Android SDK and $API is a directory for a particular API level (e.g., android-19 for API Level 19).

Note that android.jar is a JAR file and does not contain Android-style resources.
