你好stackoverflow社區,Eclipse Android應用程序在模擬器上啓動時崩潰
我是新來的android編程。我創建的應用程序「加密」始終在模擬器上崩潰,並顯示消息「不幸,加密已停止」。我正在學習本教程:https://www.sites.google.com/site/mobilesecuritylabware/3-data-location-privacy/lab-activity/cryptography/cryptography-mobile-labs/encryption-decryption/2-lab-activity/lab1。任何人都可以幫我弄清楚什麼是錯的?
非常感謝!
詳情:
的Mac OS X 10.7.5, 的Eclipse SDK 版本:4.2.2 版本ID:M20130204-1200
的EncryptActivity.java代碼是上面給出的鏈接。
應用程序名稱:加密
活動:EncryptActivity
套餐名稱:Android.Encrypt
這是logcat的:
