Use Android Studo to develop NDK's gradle configuration (debug C code)

Configuration:

The version number used is AS1.5 (you can also try a higher version number). Gradle address is Distributionurl=https\://services.gradle.org/distributions/gradle-2.8-all.zip

The NDK uses the CrystaX ndk .

Problems:
1. When I switch between the NDK configuration of MK and the NDK configuration of Gradle, I suddenly cannot debug into C + + code. And then through
Empty the Main/jni/android.mk file,
Click Build->clean,
In the Debug interface right-click tab title (such as Ctbmanager Native)->close tab (Close all Debug tab) and then can debug into the
I don't know which step to fix the problem. If you encounter a successful compilation but cannot debug C + + files, try these steps. It is not recommended to switch between the MK and Gradle configurations at the same time.
2. Suppose the C file is an error. Consider the ability to change the C file, than to solve the error is simple
