有什么问题?

我使用 Android Studio 1.0 和 gradle 2.2.1.

推荐答案

以下在 Android Studio 中使用 Android OpenCV sdk 的步骤.这是这个(1)SO答案的简化版本.

The below steps for using Android OpenCV sdk in Android Studio. This is a simplified version of this(1) SO answer.

1. 从 OpenCV.org 下载适用于 Android 的最新 OpenCV sdk 并解压压缩文件.
2. 将 OpenCV 导入 Android Studio，从 File -> New -> Import Module，在解压的 opencv 存档中选择 sdk/java 文件夹.
3. 在导入的 OpenCV 模块下更新 build.gradle 以更新 4 个字段以匹配您的项目 build.gradle a) compileSdkVersion b) buildToolsVersion c) minSdkVersion 和 d) targetSdkVersion.
通过应用程序 -> 模块设置
4. 添加模块依赖，然后选择依赖项选项卡.点击底部的+图标，选择Module Dependency并选择导入的OpenCV模块.
   • 对于 Android Studio v1.2.2，要访问模块设置:在项目视图中，右键单击依赖模块-> 打开模块设置

1. Download latest OpenCV sdk for Android from OpenCV.org and decompress the zip file.
2. Import OpenCV to Android Studio, From File -> New -> Import Module, choose sdk/java folder in the unzipped opencv archive.
3. 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.
4. Add module dependency by Application -> Module Settings, and select the Dependencies tab. 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

步骤 (6) 是因为 Android Studio 需要 app/src/main/jniLibs 中的原生库，而不是旧的 libs 文件夹.对于 Android OpenCV 的新手，不要错过以下步骤

Step (6) is since Android studio expects native libs in app/src/main/jniLibs instead of older libs folder. For those new to Android OpenCV, don't miss below steps

• include static{ System.loadLibrary("opencv_java");}(注意:对于 OpenCV 版本 3，在这一步你应该加载库 opencv_java3.)
• 对于第 (5) 步，如果您忽略任何平台库(如 x86)，请确保您的设备/模拟器不在该平台上.

• include static{ System.loadLibrary("opencv_java"); } (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.

OpenCV 是用 C/C++ 编写的.Java 包装器是

OpenCV written is in C/C++. Java wrappers are

1. Android OpenCV SDK - OpenCV.org 维护了 Android Java 包装器.我推荐这个.
2. OpenCV Java - OpenCV.org 维护自动生成桌面 Java 包装器.
3. JavaCV - 由独立开发人员维护的流行 Java 包装器.不是 Android 特定的.此库可能与 OpenCV 较新版本不同步.

1. Android OpenCV SDK - OpenCV.org maintained Android Java wrapper. I suggest this one.
2. OpenCV Java - OpenCV.org maintained auto generated desktop Java wrapper.
3. JavaCV - Popular Java wrapper maintained by independent developer(s). Not Android specific. This library might get out of sync with OpenCV newer versions.
