Parse error

Hello, I encountered a “parse error: There was a problem parsing the package” while installing my APK file on my phone.

The unsigned apk installs and works fine but the signed apk gives “parse error”.

Could it be because i deleted my SDK folder and re-installed it?

A Google search for that error brings quite a few suggestions, such as this one "There is a problem parsing the package"

Does this fix,
I’m facing the same error

Fixed:
You must download google play services, google respiratory and google usb driver in your android sdk
