Release mode setting

hi
i want to publish a game but i am confused about its required setting. i want to turn off debug mode.

in BuildNative.sh i have:
“$NDK_ROOT”/ndk-build NDK_DEBUG=0 ~~C
in Application.mk i have:
APP_STL := gnustl_static
APP_CPPFLAGS :=~~frtti

in AndroidManifest.xml i have:
android:debuggable=“false”

is that all? or i should do more?
is there any guide for publishing a game?
