Dear EVERNOTER Users,
I got the same problem with you I read what all you wrote regarding this ... and thanks God, I solved it.
Agreed with you all that up to now EVERNOTE FOR ANDROID has not the facility to do this, so use your NOTEBOOK, LAPTOP, or PC and this is the way that I solved the problem:
Go to https:/evernote.com and SIGN IN ... will appears three columns: on the left side is the operational ICON, in the middle is your NOTES, and on the right side is the DETAIL of selected note.
Move your cursor to left side then click the NOTEBOOKS ICON ... will appears NOTEBOOKS and anything like on your ANDROID smartphone
Shift your cursor to TRASH ... then appears "TRASH" on the top of this column and "Empty trash" below the word "TRASH"
Click "Empty trash" for deleting all notes on the Notebooks or you can also delete one by one by shifting your cursor to your selected note ... then appears "Erase" and "Restore", so then click "Erase".
DONE ... log out from EVERNOTE, it has not complete yet ... Go back to your ANDROID smartphone
Open EVERNOTE on your ANDROID smartphone, then SYNC it by tapping the bottom menu (I hope we have a similar version) as usually mentioned LAST SYNC and DATE. Wait till it finish to sync.
COMPLETELY DONE by now ... so Good Luck to all
