Hi Friend,
Today i am going to discuss alarm service, that provide by Android.
Using android alarm manager service we can start any activity at a particular time.
we can create time related utility application.
i am going to example of simple alarm application using date pecker and time pecker widgets and alarmservice.
Splash Activity code:-
In this activity i had used animation and custom design so you have to create
i. res/anim folder and make a blink.xml file, code given below:-
android:toAlpha="1.0"
android:interpolator="@android:anim/accelerate_interpolator"
android:duration="600"
android:repeatMode="reverse"
android:repeatCount="3"/>

android:color="#00ff00" />
android:width="5dp"
android:color="#ff0000"
android:dashWidth="3dp"
android:dashGap="2dp" />
android:endColor="#ffffff"
android:centerColor="#ffffff"
android:startColor="#ffffff"
android:angle="270" />
android:width="3dp"
