/* AndroidManifest.xml snippet:
<application ... >
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".SecondActivity" />
</application>
*/We added a click listener to the button in MainActivity. When clicked, it creates an Intent to start SecondActivity and calls startActivity to navigate.
SecondActivity is a simple screen that shows a TextView with a welcome message. We set this view directly in code for simplicity.
Both activities are declared in AndroidManifest.xml. This is required so Android knows about them.
