Answer 1

If you're trying to install a signed APK after using a debugging mode APK, Android will detect differences in signature, and refuse to install it.

Make sure you've uninstalled the unsigned debugging APK first from the device, and try to install again.

Answer 2

Please check available disk space on the target Android Device before doing any actions. For most of cases it is a due to insuffisant space on the device.
