Apps NDK c++ graphics engine integration EGL create context Native or not

[Anon11]

Hello I have just started getting into the depth of ndk. I have seen some books create an egl context on java side and render object on the native side.While some others create egl natively and render natively. Is there any performance penalty of creating egl context java side and what would you advise to do.

Also any useful books for starters in NDK you can recommend, I keep finding books which just throw code at you and explain in 3 lines what it does not how it does things.
