Great job & course! Getting deeper in core aspects of your App, just a little point : - Some credito/week more extra & practical exam about testing, with exercises to complete with all framework you explained.

Thanks for your decication.

Nice course, great explanation of non-obvious potential flaws (essentially security flaws which might be not evident even for an experienced Android developer). Quite long lectures on other obvious topics though

Helped me understand the security features of android. The examples were explained very well. Testing was covered to a good extent in this course.

Concepts were taught exceptionally with god examples, but more help is needed for completing all the quiz

Great presentation of material. Not so much useful information on Android platform vulnerabilities.

There could be more code examples but overall everything was perfect as it should be.

This course is for beginners. There is need more tasks.

Very Useful and very intelligent instructor, Thank you.

Great!!

so hard

Non optional programming assignments would be quite helpful to learn the curriculum throughly

good for learning but the tests are way too hard

very hard to solve the quiz.

Quiz is ambiguous

it would have been better than this regarding to the material, i think it need some useful written material as well as the recorded ones, walk through are a little bit confusing,

best luck

personally speaking, the contents are not helpful. and the multiple-choice quizzes stuck me a lot.
