I’m trying to start this activity from another activity using an intent. I’m not sure what’s wrong or if I’m missing something because it force closes at the onCreate() I tried to look up the errors from the logcat but I haven’t had any luck. Here’s the logcat from when it starts this activity.<\/p>\n

    Make sure you’re using the latest revision of the support library(13) which is what contains the DrawerLayout and other relevant classes. Copy the .jar for the support library to the \/libs folder of your project. Finally, Update ADT to the latest version. Logcat is complaining<\/p>\n

    Its something av noticed after updating my ADT. To solve this just make sure if you have referenced any external libraries in your project, you should ensure that they are ticked under Order and Export. Left click project> click Java Build Path>Order and Export> check Android Private Libraries<\/p>\n<\/li>\n<\/ol>\n
