步驟IntelliJ IDEA的新libgdx項目運行重現：NullPointerException異常時藉助Android
- 下載setur.jar - http://libgdx.badlogicgames.com/download.html
- 生成桌面項目，Android，iOS設備HTML
- 開放的IntelliJ IDEA，按打開，和選擇的build.gradle
- 等待的gradle時會做的工作人員，比運行Android項目
我面臨着一些奇怪的問題：
- 15時32分20秒編纂11秒成功完成
- 15時32分20秒的NullPointerException：空
- 15點32分30秒錯誤報告 錯誤提交反饋：空 考慮在Android的問題跟蹤
創建一個問題，如果我按NullPointerException異常（鏈接），似乎有消息和堆棧跟蹤：
消息：插件Android支持中的異常。 x分鐘前。自上次清除以來發生了2次。禁用插件... < - 這是一個鏈接（如果我按這個，比Android將不會被IDEA可見在所有
堆棧跟蹤：

可能重複[？什麼是空指針異常，以及如何解決呢（http://stackoverflow.com/questions/218384/what-is-a-null-指針異常和如何做我修正它） – LearnCocos2D 2014-10-31 19:00:11
我還沒有寫任何代碼，我知道什麼是NullPointerException意味着..我不知道該怎麼辦，當有什麼問題的庫，這是需要運行成功的項目..我運行了libGDX項目開箱即可..和空指針出現..有人可以嘗試建立新的libgdx項目在這個時候？謝謝 – Aleksandrs 2014-10-31 20:40:48
你使用的是android studio（而不是intellij ultimate）嗎？當直接使用Gradle時它工作嗎？也可能是你安裝的android sdk等問題。所有這些android/swing/awt stacktrace看起來都不像GDX的問題，但更像是一個帶有工具的問題。 – cfrick 2014-10-31 20:44:14
