Expo app is not installing on Android emulator

[rizwanahmed19]

Description

After creating a new project, I ran 'yarn run android' but instead of getting the expo app on the emulator I'm getting an error.

Expected Behavior

Expo app should be installed on my emulator and my app should be up and running.

Observed Behavior

I'm getting an error in the terminal while running the packager. Although I'm getting the QR code.

If there's an error message, please paste the full terminal output and error message in this code block:

Error running adb: Failed to install C:\Users\Rizwan\.expo\android-apk-cache\Exponent-1.16.1.apk: Failure [INSTALL_PARSE

I had the same problem (on macOS), can confirm that deleting the .expo/android-apk-cache directory and re-running yarn start android fixed it for me

deleting that dir helped me resolve my issue where nothing at all happens after "11:35:50 AM: Starting Android..."
