MasterDetailExample Android App on Eclipse - Errors

As soon as I create my project "MasterDetailExample" it is filled with errors and I'm not sure why. I've been following the Android track and can't continue because of these errors.

Errors Consist of:

Sorry about the trouble here! I will be refreshing this course soon which will solve these specific issues. In the mean time, please recreate the project and set the minimum SDK to 14. There are a lot of new backwards-compatibility issues when trying to use an earlier minimum SDK like we had when the project was first recorded.

Okay thanks. How do I set the minimum SDK to 14?

When you create the project, set the "Minimum Required SDK" to 14 instead of 11. See the 4:15 mark of the video.

I am having a similar problem with Eclipse. I just pressed the bebug problem and the first 1 stopped. The second is that as I follow the video ( starting the project). We r supposed to choose 4.2 mine only aloows 4.4 and no other options. But when i try to launch an emulator I am told that the image for 4.4 hasn't loaded. So I rrestarted it and sure enough 4.4 was loading. It never came up wven when after I restarted again it keeps saying that only a certain amount of Mb has loaded . The highest it went to was 113Mb out of 555Mb. How can I resolve this issue. Thank you in advance guys.

Not yet, I can't use Eclipse at all and I've run into problems with importing Genymotion to Androis Studio. I will try it again tommorrow if I get past these problems I will let you know. Thanks for your response.
