Question

I’m trying to use Android annotations framework because it seems quite powerful. I’m quite stuck to configuring my first project based on it.
I followed every step of the wiki but it doesn’t generate any file after a build.

So when I ask for a generated class from the manifest:

<activity android:name=".MyActivity_"
   android:label="@string/app_name">

I get an exception:

java.lang.ClassNotFoundException

My activity is exactly the same one as in the wiki:

@EActivity(R.layout.main)
public class MyActivity extends Activity {

    @ViewById
    EditText myInput;

    @ViewById(R.id.myTextView)
    TextView textView;

    @Click
    void myButton() {
         String name = myInput.getText().toString();
         textView.setText("Hello "+name);
    }
}

Any ideas?

EDIT: Just found out a directory “.apt_generated” is made but it’s empty after the build.

This seems to be an AndroidAnnotations bug, and should be reported on the dedicated bug tracker, here : http://code.google.com/p/androidannotations/issues/entry . You could also use the AndroidAnnotations mailing list, http://groups.google.com/group/androidannotations

First, I have a few questions :

Which IDE do you use : Eclipse, Netbeans, IntelliJ ? Which version ?

Do you use Maven, Ant, or only your IDE to build the project ?

Your problem may be due to a few things : annotation processing not triggered, a bug in AA, or the files generated in a folder not part of the classpath.

In Eclipse, you may get more information from the “Window > Show View > Error Log” view. If annotation processing is triggered, you should see some messages about AndroidAnnotations.
