Facebook Android SDK Session openForPublish does not create a new session

In the Android Android SDK when I call

Session tempSession = new Builder(this).build();
Session.setActiveSession(tempSession);
tempSession.openForRead(new OpenRequest(this).setPermissions(FB_PERMISSIONS));

He gets an FB session, and every thing works as usual. But when I replace Readwith Publish. those. should

Session tempSession = new Builder(this).build();
Session.setActiveSession(tempSession);
tempSession.openForPublish(new OpenRequest(this).setPermissions(FB_PERMISSIONS));

It gives an error saying that the session is empty and cannot obtain publish permissions for an empty session.

Could you tell us why this is so and what would be the best way to handle this?

Short answer: do not call openForPublish. Call openForRead and then requestNewPublishPermissions later if you need to publish permissions.

    session.openForRead(openRequest);
}
else
