I want to make an animated splashscreen and the Motion Layout should start automatically when you start the app. What can I do to make the Motion Layout start automatically?

Add the line autoTransition="animateToEnd" to your transition
<Transition
motion:constraintSetStart="@+id/start"
motion:constraintSetEnd="@+id/end"
motion:autoTransition="animateToEnd"
motion:duration="1000">
First, assign an ID to MotionLayout in xml.
then write below codes in your activity:
MotionLayout motionLayout = findViewById(R.id.motion_layout);
motionLayout.transitionToEnd();
if you want to reverse transition use this line of code:
motionLayout.transitionToStart();
The motion:transitionFlags="disableIntraAutoTransition" will avoid the animations reanimating if the actual state is changed programmatically or by the user.
<Transition
motion:constraintSetEnd="@+id/end"
motion:constraintSetStart="@id/start"
motion:autoTransition="animateToEnd"
motion:transitionFlags="disableIntraAutoTransition"
motion:duration="1200">
</Transition>
