Android

Hello everyone.
In order to develop Android programms, I am using IntelliJ IDEA 2020 (x64) on Windows 10 that is running on Intel core 2 Duo processor.
To debug and run the app, I use the Nexus 5 hardware and Nougat x86 System Image (API Level 24).
Also I’ve checked Intel x86 Emulator Accelerator (HAXM Installer) in SDK Tools and enabled Virtualization Tech in System BIOS.
After running the app, Device is shown to me, but my app doesn’t exist in it and this message pops up:

Emulator: Warning: Quick Boot / Snapshots not supported on this machine. A CPU with EPT + UG features is currently needed. We will address this in a future release.

Please help me.

According to Google Play meta data policy:

I cannot add "Word blocks and vertical/horizontal word lists" in my store listing full description.

I have written instructions for my app in this manner. Am i violating their policy? I think I'm not because these are sentences not word lists. What do you think?

Here’s how it works:
Download the Example on-demand delivery app on your preferred device
Sign-up by providing your necessary details (name, phone, and e-mail address)
Set your pick-up and drop off locations
Choose a payment method (card or cash)
Enter your shipping details, the receiver’s name, and phone (if it’s not you)
Confirm the booking

Thanks in advance for the replies.
