in Germany, If I quit my legal job (resign) will I still get
unemployment allowance? (I've been working for a full year, and payed
social insurance)

Dear Abomy, 

I am answering this in comment, since I am not 100% sure of my answer.

The Arbeitsamt site refers to cases, where you ended your own work, as
eligable to unemployment benefits (see for example "Erklärung zur
Beendigung des Beschäftigungsverhältnisses"
<http://www.arbeitsamt.de/hst/services/lis/alg/antrag/erklaerung_zur_beendigung_beschaeftigungsverhaeltnis.html>).

If you worked for a year, you could get 6 months of unemployment
benefit. The caculations of the weekly sum are available at the
Arbeitsamt site, <http://www.arbeitsamt.de/hst/services/lis/alg/selbstberechnung/index.html>.
