Is there any way to delete contact from contact list?

Question

My application requires an alternate contact while installing an app.When I run install & register app there are no contacts in new devices bydefault.

I have found an adb command to add an contact in contact list

adb shell am start -a android.intent.action.INSERT -t vnd.android.cursor.dir/contact -e name 'Alternate Contact' -e phone 72xxxxxxxx

But now i am unable to delete same contact after execution . Tried multiple combination of parameters with next command, but it is not working. adb shell am start -a android.intent.action.DELETE -t vnd.android.cursor.dir/contact -e name 'Donald Duck' -e phone 72xxxxxxxx

Please share if there is an adb command to delete contact.

EDIT : adb shell pm clear com.android.providers.contacts command will clear all contacts from contact list.

To add contact (where're name = 'Mozart', number = '+380505005050')

$ adb shell am start -a android.intent.action.INSERT -t vnd.android.cursor.dir/contact -e name Vasya -e phone +380505005050

To edit contact (where's id = 1)

$ adb shell am start -a android.intent.action.EDIT content://com.android.contacts/contacts/1

To remove contact (where's id = 1)

$ adb shell content delete --uri content://com.android.contacts/contacts/1

To remove all contacts at once

$ adb shell pm clear com.android.providers.contacts

To view specific contact (where's id = 1)

$ adb shell am start -a android.intent.action.VIEW content://com.android.contacts/contacts/1

To list all contacts

$ adb shell content query --uri content://com.android.contacts/contacts
