我正在使用Ionic框架和AngularJS構建應用程序。它曾經運行良好，現在它一旦在模擬器和Android設備中啓動就會崩潰。奇怪的是它在Ionic View應用程序中運行良好（http://view.ionic.io/）。 logcat說這個錯誤是一個NullPointerException。Android模擬器和設備上的離子應用程序崩潰
真正令我擔心的是我沒有做任何大的改變，另一個應用程序也開始失敗。 Ionic Cordova如何失敗？
完整的logcat墜機的部分說：

真的讓我擔心的是我沒有做任何重大改變？你有沒有把你的項目交給Crossover？ （personnaly，crossover崩潰了我所有的項目;））你有沒有添加/刪除cordova插件？我建議你去離子平臺rm android＆ionic平臺在重建之前添加android – aorfevre
你是對的，就是這樣。它現在工作正常，謝謝。 –
