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

Did anybody have similar problem with this, I import android project and I get errors like

I got errors to delete all @Override above functions. I have Windows 7 x64, jvm7 x64. Does anyone have clue what is wrong ?( I done Android Tools -> Fix Project Properties but didn;t help )

That isn't the problem, Jack. Android SDK isn't x64, but works ok with x64 jvm (and x64 eclipse IDE).

As helios said, you must set project compatibility to Java 5.0 or Java 6.0.

To do that, 2 options:

1. Right-click on your project and select "Android Tools -> Fix Project Properties" (if this din't work, try second option)
2. Right-click on your project and select "Properties -> Java Compiler", check "Enable project specific settings" and select 1.5 or 1.6 from "Compiler compliance settings" select box.

1. Go to the project folder and right click on it -> properties -> check off the read only box and click ok

2. Right-click on your project and select "Android Tools -> Fix Project Properties"

3. Right-click on your project and select "Properties -> Java Compiler", check "Enable project specific settings" and select 1.5 or 1.6 from "Compiler compliance settings" select box. (try all the levels one by one just in case)

4. Under Window -> Preferences -> Java -> Compiler, set Compiler compliance level to 1.6 or 1.5.

Hopefully it will settle the problem.
