Black screen on Android - My app, Hello world and samples

Hi guys!
I know there are hundrets of “black screen” posts, but I didn’t found an answer in those. So now I am asking you. Please help!
So after setup Cocos 2dx 3.10 (with ndk 10, testing on samsung galaxy A3 w/Lollipop), I tried to run simple hello world program. All went as it was written in tutorials (http://www.gamefromscratch.com/post/2014/09/29/Cocos2D-x-Tutorial-Series-Installation-Creating-a-Project-and-Hello-World.aspx, , cocos programmers guide…) but when I open application on my phone, there is just black screen showing.
As a test, i download a game awalible on cocos named arkaflow-master , and the result was the same.
Even when I write my own code, there was stil black screen.
Why does this happening? Solution maybe?

You should compile and run the hello world project if that doesn’t work I don’t think going to another source code will help you ? Did you use the cocos console ?
Tell more details.

I use Eclipse ADT. Hello world build succesfully, but the result (the app) wasnt working properly on my phone.

What do you mean ? It only fails on your phone ?

I havent try it anywhere else than on my phone.
The app opens but the screen is black.

Is it giving you any useful logcat output?
Could be failing to load resources because of a path / linkage thing, and you’re just seeing Cocos “run” nothing.

With that information that he say it’s impossible to help. I only say that please use the console to compile the hello world project.
I write a tutorial I try to explain very very clearly.

Usicn cocos command line, it works. So can anybody explain the problem when I use eclipse.

@iaprogramsUP Did you enable the CDT Builder ?
If you don’t enable that the project compiles but it will go black screen maybe is that the problem.

Yes. Now it works!
