Eclipse NDK JNI Configuration

The Jni folder will appear, i.e. below Hello_ndk.cpp and android.mk

At this point, the following problems will occur, although some people on the internet said that can be solved in the following way, yes, but there will be another problem, that is, if you want to build in the JNI directory C + + engineering and class, you will find that the corresponding

Find more ways to get online (feel Bad):

Another method is found later:

Select the project, right-->properties, click c/C + + general expansion, click Path and Symbols, on the right includes, click Add, the Ndk folder under the JNI header file and the corresponding C + + header file to add in. Be sure to fill in the complete path, such as the two paths I added are:

E:\AndroidNDK\android-ndk-r10c\toolchains\mipsel-linux-android-4.8\prebuilt\windows-x86_64\lib\gcc\ Mipsel-linux-android\4.8\include

E:\AndroidNDK\android-ndk-r10c\platforms\android-19\arch-arm\usr\include

can solve the problem.

This is followed by the creation of the appropriate Java interface to communicate with C/s:

and introduce so libraries in Java code

The GetString class generated header files, the online comparison is common with the cmd command generated, but this way is too troublesome

The following is done through the direct configuration in eclipse

1, first in the project to create a new

The code then references the following

Configuring the ant compiler header file

The following is a compilation of C + + issues. Online has been compiled directly with Ndk-builder, but that method is too complex, each construction project must be configured a large heap, in order to use, which is now directly with the CDT, according to the same method configuration, can automatically generate CDT builder
