操作方法

（01）一般出現這個問題主要是沒有在項目的裏註冊使用activity，主要就是這句： imeException: Unable to instantiate activity ComponentInfo{com.example.tomato/com.example.alarmtest.AppStart}: sNotFoundException: com.example.alarmtest.AppStart

（02）上面它已經就說，你沒有實例化com.example.tomato/com.example.alarmtest.AppStart，tomato是項目名字，AppStart是沒有實例化的activity。這就明白了，檢查這下，註冊<activity android:name="com.example.tomato.AppStart"/>。

（03）但有時你發覺你已經註冊，這時你要仔細檢查，看看是不是包名寫錯了，仔細排查錯誤。就能解決了。
