# OpenCV Android
Easy way to integrate OpenCV into your Android project via Gradle.
**No NDK dependency needed** - just include this library and you are good to go.
## 🚨 Breaking Changes
* OpenCV Contribution's package naming has been changed to make it as per the naming guideline.
* **Old**: ```opencv:VERSION-contrib```
* **New**: ```opencv-contrib:VERSION```
### 🚀 Releases
Each versions is available in only OpenCV as well as OpenCV with contributions.
##### 4.x versions
* **4.5.3.0** ‼️
* 4.5.2
* 4.5.1
* 4.5.0
* 4.4.0
‼️ Please use `4.5.3.0` instead of `4.5.3`. They are both the same versions, however, `4.5.3` has some runtime issues on some of the Android versions while `4.5.3.0` works fine.
##### 3.4.x versions
* **3.4.15**
* 3.4.14
* 3.4.13
* 3.4.12
* 3.4.5
* 3.4.1
## 👩💻 How to Integrate 🧑💻
* Add `mavenCentral` to your project's `build.gradle` file's **repositories** section if not already present.
```groovy
repositories {
mavenCentral()
}
```
* Add either the normal or contributions version in the **dependencies** of your module.
``` groovy {
// opencv
implementation `com.quickbirdstudios:opencv:VERSION`
// opencv with contributions
implementation `com.quickbirdstudios:opencv-contrib:VERSION`
}
```
* Initialize OpenCV before using it.
```kotlin
if (!OpenCVLoader.initDebug())
Log.e("OpenCV", "Unable to load OpenCV!");
else
Log.d("OpenCV", "OpenCV loaded Successfully!");
```
## ‼️ Want to use OpenCV as source Dependency?
* Checkout the Repository. There will be an empty project with placeholder for the opencv source.
* Download the source from your desired release.
* Unzip the folder. The name of the folder will be `opencv_VERSION` or `opencv-contrib_VERSION`. Copy this folder to the project and keep it at the same level as the `app` folder.
* Open `settings.gradle` and replace the VERSION with the OpenCV version you have downloaded.
```groovy
// Remove/comment out the one you aren't going to need
include ":opencv_VERSION"
include ":opencv-contrib_VERSION"
```
* Open app/build.gradle and replace the VERSION with the OpenCV version you have downloaded
```groovy
// Remove/comment out the one you aren't going to need
implementation(project(":opencv_VERSION"))
implementation(project(":opencv-contrib_VERSION"))
```
* Sync and run the project. You should see the screen with the text `OpenCV Loaded Successfully`.
