Android requires compiler compliance level 5.0 or 6.0. Found '1.7' instead. Please use Android Tools > Fix Project Properties

I have added this line of code to my android app:

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

it has worked in other peoples apps but on mine it comes up with a red cross next to is which when I hover over it says:

Multiple markers at this line
- Syntax error on token ">>", invalid AssignmentOperator
- Syntax error on token ",", TypeArgument2 expected after this token
- Syntax error on tokens, delete these tokens

I also have a error displayed on the 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 at 1.5 but have tried 1.6 and 1.7 and no fix)

Please help 🙁

Answer 1

First ,You Should Read Java Collections And Generics

ArrayList<HashMap<String, String>> mylist = new ArrayList<HashMap<String,String>>();

and set Compliance level 1.6, because 1.7 is not compatable yet. Java 1.5 gives @Override anotation error. Because @Override introduced in 1.6.

project -> properties -> java compiler -> compiler compliance level->Set it at 1.6
