Android Studio + OpenCV
发表回复
Download latest OpenCV sdk for Android from OpenCV.org and decompress the zip file.
Import OpenCV to Android Studio, From File -> New -> Import Module, choose sdk/javafolder in the unzipped opencv archive.
Update build.gradle under imported OpenCV module to update 4 fields to match your project build.gradle a) compileSdkVersion b) buildToolsVersion c) minSdkVersion and d) targetSdkVersion.
Add module dependency by Application -> Module Settings, and select the Dependenciestab. Click + icon at bottom, choose Module Dependency and select the imported OpenCV module.
For Android Studio v1.2.2, to access to Module Settings : in the project view, right-click the dependent module -> Open Module Settings
Copy libs folder under sdk/native to Android Studio under app/src/main.
In Android Studio, rename the copied libs directory to jniLibs and we are done.
include static{ System.loadLibrary("opencv_java"); } or static{ OpenCVLoader.initDebug(); } (Note: for OpenCV version 3 at this step you should instead load the library opencv_java3.)
For step(5), if you ignore any platform libs like x86, make sure your device/emulator is not on that platform.
Android OpenCV SDK – OpenCV.org maintained Android Java wrapper. I suggest this one.
OpenCV Java – OpenCV.org maintained auto generated desktop Java wrapper.
JavaCV – Popular Java wrapper maintained by independent developer(s). Not Android specific. This library might get out of sync with OpenCV newer versions.
