Answer 1

If you're trying to build your app to an emulated Android device, it might need to be cold-booted. Go to Tools -> AVD Manager, and on the Virtual Device you're trying to use, click the drop-down arrow to the far right and select "Cold Boot Now".

Give the emulator a few moments to start, and if it does so without error, try building your app again and see if it now loads properly.

Answer 2

I Spent 4 to 5 HOURS to solve this issues and tried my possible solution, but no Luck, but FINALLY, I did it from myself, So may be it will help anybody in future.

What i did :

1. i Changed My Emulator Targeting Hardware/Phone From Pixels to Nexus 5x (Not Any Pixel hardware/Phone worked for me.
2. i Changed System Image From R (Api Level 30) to Q (Api Level 29). And its Done!!

i am attaching some reference screenshots to better understand.

• Selecting Hardware Image

• Selecting System Image, Under x86 Image Tab

• Final Result, After Emulator Created Sucessfully
