Attending the 5-day Android programming codecamp was a real intensive and rich experience for me. The instructor is a great helper and smooth teacher. The codecamp material, especially the hands on lab are pretty detailed, well organized, very helpful and straight forward for understanding the concept and then exercise them. The course was a huge step for me to get into android development, and I'm glad I've attended the codecamp.

First of all, thanks for the amazing training, I'd never reached that level of Android knowledge in this short time. For me, mobile programming is a new field and that was a right start to dig deeper into it. So, thank you again for the 5-day codecamp.

Android codecamp from JPassion.com was a great opportunity to learn a new and popular technology. The course is comprehensive and contains almost everything you need to learn about Android if you are testing on the emulator. This codecamp has taught me a lot of new concepts whether they be related to android or other fields. The experience of learning and taking a course at javapasson.com itself was great and was definitely worth the time and effort. Thank you.
