java - Android requires compliance level 5.0 or 6.0 -


possible duplicate:
android requires compiler compliance level 5.0 or 6.0. found '1.7' instead. please use android tools > fix project properties

i have added line of code android app:

arraylist<hashmap<string, string="">> mylist = new arraylist<hashmap<string, string="">>();

it has worked in other peoples apps on mine comes red cross next when hover on says:

multiple markers @ line - syntax error on token ">>", invalid assignmentoperator - syntax error on token ",", typeargument2 expected after token - syntax error on tokens, delete these tokens

i have error displayed on console:

android requires compiler compliance level 5.0 or 6.0. found '1.7' instead. please use android tools > fix project properties.

i have tried:

project -> android tools -> fix project properties,

project -> clean,

project -> properties -> java compiler -> compiler compliance level (currently set @ 1.5 have tried 1.6 , 1.7 , no fix)

please :(

first ,you should read java collections , generics

arraylist<hashmap<string, string>> mylist = new arraylist<hashmap<string,string>>();

and set compliance level 1.6, because 1.7 not compatable yet. java 1.5 gives @override anotation error. because @override introduced in 1.6.

project -> properties -> java compiler -> compiler compliance level->set @ 1.6
