Android multiple contacts from groups and images

Question

I want to do the following. Pick up three to five contacts out of a special group of contacts or all contacts. In the list it would be nice to show the contact image. The selected contacts should have the following information (contact-id, first name, the small version of the contact image to save it as a blob in the database)

I found solutions for the different aspects. -select multiple contacts: How to obtain the checked rows in a custom view list -show contacts from one group getting contacts from a specified group in android - photo problem Getting a Photo from a Contact

But I dont know how to put those together. It would be great if someone could help me putting it together.

Thank you very much! Frank J.

Solved it, but cant post the answer for some hours.
