Build and run Android NDK applications without Eclipse

If you already have a development environment and do not wish to use Eclipse, you can easily build and run your NDK application from makefiles or the command line.

First of all, you need to set the ANDROID_NDK_ROOT environment variable and ensure the SDK and NDK binary directories are in PATH. Here are my definitions: 

ANDROID_NDK_ROOT=/home/sam/android/android-ndk-r8
PATH="$PATH:$ANDROID_NDK_ROOT"
PATH="$PATH:/home/sam/android/android-sdk-linux_x86/platform-tools"
PATH="$PATH:/home/sam/android/android-sdk-linux_x86/tools"

This is best defined in one of your shell’s startup scripts such as .zshenv.

Build and install package

Now, whenever you are in an NDK project’s directory, build the project using: 

ndk-build && ant release

And to upload it to the emulator or to a connected device: 

ant release install

That’s all! Those two simple commands can easily be launched from your preferred development environment.

Update: ant compile no longer exists in recent SDKs; replaced with ant release.

Run package

You can use adb to run any application remotely. For instance: 

adb shell am start -a android.intent.action.MAIN -n $PACKAGENAME/.$ACTIVITYNAME

Both package name and activity name can be found in your AndroidManifest.xml.

This is only build and install, how about run?!

@anonymous: you’re right, I lied about the running! I added the relevant information.

Thanks for this article. I might also like to say that it can end up being hard if you find yourself in school and merely starting out to create a long credit rating. There are many learners who are only trying to endure and have long or good credit history are often a difficult issue to have. aagkdefdgeeedabe

They are leading the review due to the expanded rivalry, organizations are upgrading visitor fulfillment and keeping their current visitors as opposed to designating extra assets to pursue new ones on the grounds that the exertion of holding existing visitor is significantly less demanding than getting new ones. ​https://customersfeedback.xyz/dgcustomerfirst/
