Setup OpenCV SDK in Android Studio Project
Why Stack Overflow recommends it
Stack Overflow users link it as the step-by-step guide for getting OpenCV working in Android Studio, often when they are troubleshooting the NDK and JNI parts of that setup.

What it is
A roughly nine-minute screencast from Learn2Crack showing how to add the OpenCV Android SDK to an Android Studio project, with a companion written article. It walks through importing the OpenCV module and wiring it into an app's Gradle setup.

I followed this tutorial [this video] and in the final stage i can't compile the project. There is something wrong with my ndk, but i have no idea what to do. I tried everything, for example: NDKBuild Failure [LINK] After many changes, I'm a little confused right now. Here is the code of my build.gradle import org.apache.tools.ant.taskdefs.condition.Os apply plugin: 'com.android.application' android { compileSdkVersion 21 buildToolsVersion "21.1.2" defaultConfig { applicationId "com.example.aidan.opencvdemo" minSdkVersion 14 targetSdkVersion 21 versionCode 1 versionName "1.0" } sourceSets.main { jniLibs.srcDir 'src/main/libs' jni.srcDirs = [] //disable automatic ndk-build call } // call regular n

@abggcv Do you still get the same non-zero exit error? If you are using Windows you might want to avoid spaces name of the folder path. It was one of the suggestions I learned somewhere. Also check out the link [LINK] given by Dmitry Moskalchuk and from that - make sure the folder structure is correct, create Android,mk and application.mk files if they are not already there in app/src/main/jni . I used the following tutorial to setup opencv + the above modifications link [this video] Hope this helps!

Actually it's a whole tutorial long question. I just want to propose some external sources you can consult. First, you have to compile OpenCV with Android option. Later on give below tutorials a try: This [this video] is a nice video tutorial. This [LINK] is another nice tutorial.

I used this tutorial [this video] to make a static initialization. The code that you added is good for this type of initialization?
Cites Tim · 2016-09 · Stack Overflow · on “OpenCV and JNI setup in Android Studio”
I want to use OpenCV library in both my Java codes and JNI C++ codes in Android Studio. How can I import OpenCV library and set up the NDK environment (JNI) in the same android project in Android Studio ? I could successfully do either one, but could not do both in a project even though I have tried many times. I followed these two tutorials to set up the environment. 1. OpenCV for android [this video] 2. JNI/NDK [LINK] Does anyone have any idea why my setup was failed? Or can anyone provide me a guide to set up the environment?

package com.example.sawsanalzoubi.vision; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.util.Log; so in "import org.opencv.android.OpenCVLoader" i have encounter the following error : unused import statement import org.opencv.android.OpenCVLoader; public class MainActivity extends AppCompatActivity { private static final String TAG="MainActivity"; static { if(!OpenCVLoader.initDebug){Log.d(TAG,"OpenCV not loaded"); } else { Log.d(TAG,"OpenCV loaded"); } } static{ System.loadLibrary("opencv_java3"); } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } } this is
