操作方法

（01）一般出现这个问题主要是没有在项目的里注册使用activity，主要就是这句： imeException: Unable to instantiate activity ComponentInfo{com.example.tomato/com.example.alarmtest.AppStart}: sNotFoundException: com.example.alarmtest.AppStart

（02）上面它已经就说，你没有实例化com.example.tomato/com.example.alarmtest.AppStart，tomato是项目名字，AppStart是没有实例化的activity。这就明白了，检查这下，注册<activity android:name="com.example.tomato.AppStart"/>。

（03）但有时你发觉你已经注册，这时你要仔细检查，看看是不是包名写错了，仔细排查错误。就能解决了。
