I had seen all the issue about this problem.Not any means is the solution about this question. All I just know a bunch of empty function in class SDKManager but I could do nothing but ask you for help how to fix '''Constructor returning without calling superclass constructor'''

The tutorial is out of date, please don't follow the guide. I suggest you just try this Sample with the latest Android 4.16.2 now.

But how could I just merge it into the other project not build on it.

I am sorry for the out of date of tutorials. I know this is very hard, you have to compare the tutorials and the Sample to find out a difference and write your own project. Which aircraft are you using? If you are using M300RTK or M30 series, we suggest you switch to MSDK V5.
