I would like to see a ‘Hello world’ program written in C/C++ but made to run on Android.
I know this is possible by using NDK and JNI calls. But not able to make it work. No guides online are helpful.
Need to know to to get started.
I am developing on Windows 7 machine and also using Eclipse for ease.
Android installation path: C:\Program Files\Android\android-sdk-windows
and NDK I have extracted to: C:\Program Files\Android\android-ndk-r5
- How do I import NDK to eclipse?
- How to use C/C++ in Android?
If I could get help running a simple ‘hello world’ I can design most of my sensitive code with C++.
There are samples in the android-ndk-r5 folder + there is a nice step-by-step tutorial:
No excuses, dude. You just have to read (take a look at the Exploring the hello-jni Sample section).
1) Download NDK from https://developer.android.com/tools/sdk/ndk/index.html.
2) After this copy the location where the ndk is stored.
3) Open preferences from window menu (Eclipse -> Preferences on Mac OS).
4) Inside preferences there is Android title and click that.
5) Then open Ndk and paste the copied Ndk location inside the Edittext.
Now location of the Ndk is set in your eclipse and than
1) create new project.
2) Right click on the project and than select Android Tools and select Add Native.
Automatic creation of jni folder in your project
Install the SDK and NDK like this: https://askubuntu.com/a/732010/52975
Plug in your device via USB and run:
git clone https://github.com/googlesamples/android-ndk cd android-ndk git checkout a5fdebebdb27ea29cb8a96e08e1ed8c796fa52db cd hello-jni ./gradlew clean ./gradlew assembleDebug ./gradlew installAllDebug
Now the app should be installed in your device.
hello-jni is the simplest C example, and there are also C++ examples like
Those examples use Gradle, and there are Ant
Android.mk examples under the branch android-mk. You can build those with:
ndk-build android update project -p . -t android-23 ant clean ant debug ant installd
Tested on Ubuntu 16.04, Android 5.1.1.
1.Creating project and check NDK support.
2.If NDK is not installed ,install it from Android sdk manager.
3.Install Cmack plugin.
Upgrade Studio version above 2.2
