[android-beginners] Re: Need suggestions about testing Android applications using JPF
Bump! Has anyone got ideas on this? Verifying android applications using Java path finder features as one of the topics of Google Summer of Code 2010 (though I am exploring a narrower version of this as a course project). So I am sure this is a problem worth a look!

[android-beginners] Re: Need suggestions about testing Android applications using JPF
In my attempt to make the sample ContactManager android application
work under JPF, I did the following:
I wrote a main method with this code:
public static void main(String[] args)
{
ContactManager cm = new ContactManager();
Intent i = new Intent();
i.setComponent(new
ComponentName(ContactManager,com.example.android.contactmanager));
cm.startActivity(i);
}
And then I tried to execute this class under JPF. But I got this
error:
java.lang.RuntimeException: Stub!
at android.content.Context.init(Context.java:4)
at android.content.ContextWrapper.init(ContextWrapper.java:5)
at android.view.ContextThemeWrapper.init(ContextThemeWrapper.java:
5)
at android.app.Activity.init(Activity.java:6)
at com.example.android.contactmanager.ContactManager.init
and tracing this error, it is caused at the execution of the very
first statement:
ContactManager cm = new ContactManager();
Searching on the group led me to the following thread:
http://groups.google.com/group/android-developers/browse_thread/thread/a680b65f287e1b8c/caecec75f1b384f3?lnk=gstq=+Stub!+%09#
The discussion here essentially says that the only way to test code
that uses Android API is on a device or emulator. So am I hitting a
dead end here, by trying to explore a way to test android application
(that certainly uses Android classes) under JPF, without running the
emulator in the JPF?
I would be happy if experienced folks can confirm whether it is
impossible to test android applications in another tool, without
running the emulator in that tool.
