I have followed the doc in here : [Android Quick Start | Unreal Engine Documentation](https://docs.unrealengine.com/latest/INT/Platforms/Android/GettingStarted/index.html)

However, I could not passed the step ‘Deploy Your Level’. I choose my device it does some stuff on the right bottom corner and then ‘Launch Error!!!’ message. The output is below:
