Android or web app which allows learn new words in different language using quizes

Don't know if this question should be posted on stackoverflow but nevertheless.

I am looking for Android or web application to learn new language(German) which allows:

• add unknown word by searching for translation online(like search in dictionary)
• learn new words by playing quiz game - 4 answers and 1 is
  correct.

I don't want to add translation manually. I do want to add my own words. Ideally with application should support different language pairs like: english->german, russian->english and etc

Is there an app which supports these cases?
