	<Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Button" />
	<Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Button" />

Q30. You want to open the default Dialer app on a device. What is wrong with this code?

val dialerIntent = Intent()
val et = findViewById(R.id.some_edit_text)
dialerIntent.action = Intent.ACTION_DIAL
dialerIntent.data = Uri.parse("tel:" + et.getText()?.toString())
startActivity(dialerIntent)

startActivityWithResult() should be used instead of startActivity() when using Intent.ACTION_DIAL.
For Intent.ACTION_DIAL, the Intent option Intent.FLAG_ACTIVITY_NEW_TASK must be added when using this dialerIntent.
The dialerIntent will cause an ActivityNotFoundException to be thrown on devices that do not support Intent.ACTION_DIAL.

The permission android.permission.CALL_PHONE must be requested first before Intent.ACTION_DIAL can be used.

You have full control over the user experience. The app that handles the camera intent will respect your design choices.
You do not have to design the UI. The app that handles the camera intent will provide the UI.

Q33. When would you use the `ActivityCompat.shouldShowRequestPermissionRationale()` function?

when a user first opens your app and you want to provide an explanation for the use of a given permission
when a user has previously denied the request for a given permission and selects “Tell me more”
when a user has previously denied the request for a given permission and you want to provide an explanation for its use

when a user has previously denied the request for a given permission and selected “Don’t ask again,” but you need the permission for your app to function

Q34. You would like to enable analytics tracking only in `release` builds. How can you create a new field in the generated `BuildConfig` class to store that value?

	release {
		buildConfig 'boolean', 'ENABLE_ANALYTICS', 'true'
	}
}

xml
	<activity android:name=".ExampleActivity">
		<intent-filter>
			<action android:name="android.intent.action.SEND" />
		</intent-filter>
	</activity>

xml
	<activity android:name=".ExampleActivity">
		<intent-filter>
			<action android:name="android.intent.action.MAIN" />

	</activity>

xml
	<activity android:name=".ExampleActivity">
		<intent-filter>
			<action android:name="android.intent.action.VIEW" />
		</intent-filter>
	</activity>

Explanation: Intent filters are used to make activities accessible to other apps using intents. So we have to choose option which have no intent filter to make sure it is not accessible by intent
