从活动中创建.jar

Question

Doe anyone know how to create a .jar file from one activity? I don´t need anything else, just to create a .jar from the Activity class itself (I don't need the .xml file).

is it possible?

Answer 1

You can try to use plain export menu to do this. In Eclipse it can be done by Right button click on project->Export->Java->JAR file and select only your Activity's file.

Answer 2

You can export your class.In eclipse

select your class,do write click on it export --> java --> jar file

Answer 3

You can create a new Android project which contains a class like:

public class ClassA extends Activity {
...
}

Be sure to create ONLY a class, no Android Activity. Then you can export a jar file of it.
