java.lang.RuntimeException：無法實例化活動

Question

很抱歉，我看到過類似的帖子，但是對於我發現的所有帖子，它們都沒有幫助。 重新格式化筆記本電腦並使用多種工具來恢復代碼時，我丟失了項目，但這並不是我的正確方式。 再次修復后，我仍然收到這些錯誤，我是Java的新手，所以請解釋一下。

Answer 1

嘗試：

1. 刪除import com.sundaysalmody.R; 從您的SundayPsalmody活動中的進口清單中
2. 檢查是否在Manifest.xml文件中正確聲明了所有Activities 。
3. 清理並構建您的項目。
4. 運行應用程序
