Android studio单独导入官方例程camera-calibration

1.官方例程camera-calibration

在这里插入图片描述

2.将官方例程camera-calibration copy到AndroidStudioProjects项目目录下

在这里插入图片描述

3修改AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android=“http://schemas.android.com/apk/res/android”
package=“org.opencv.samples.cameracalibration”

<applicationandroid:label="@string/app_name"android:icon="@drawable/icon"><activity android:name="CameraCalibrationActivity"android:label="@string/app_name"android:screenOrientation="landscape"android:configChanges="keyboardHidden|orientation"><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter></activity>
</application><supports-screens android:resizeable="true"android:smallScreens="true"android:normalScreens="true"android:largeScreens="true"android:anyDensity="true" /><uses-permission android:name="android.permission.CAMERA"/><uses-feature android:name="android.hardware.camera" android:required="false"/>
<uses-feature android:name="android.hardware.camera.autofocus" android:required="false"/>
<uses-feature android:name="android.hardware.camera.front" android:required="false"/>
<uses-feature android:name="android.hardware.camera.front.autofocus" android:required="false"/>

4.将opencv sdk当作module导入，并设置依赖：

5.下面是修改Gradle的各个文件

在这里插入图片描述
rootProject.name = “camera-calibration”
include ‘:libopencv’

在这里插入图片描述

apply plugin: ‘com.android.library’

def openCVersionName = “4.5.0”
def openCVersionCode = ((4 * 100 + 5) * 100 + 0) * 10 + 0

println "OpenCV: " +openCVersionName + " " + project.buildscript.sourceFile

android {
compileSdkVersion 26

defaultConfig {minSdkVersion 21targetSdkVersion 26versionCode openCVersionCodeversionName openCVersionNameexternalNativeBuild {cmake {arguments "-DANDROID_STL=c++_shared"targets "opencv_jni_shared"}}
}buildTypes {debug {packagingOptions {doNotStrip '**/*.so'  // controlled by OpenCV CMake scripts}}release {packagingOptions {doNotStrip '**/*.so'  // controlled by OpenCV CMake scripts}minifyEnabled falseproguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'}
}
compileOptions {sourceCompatibility JavaVersion.VERSION_1_6targetCompatibility JavaVersion.VERSION_1_6
}sourceSets {main {jniLibs.srcDirs = ['native/libs']java.srcDirs = ['java/src']aidl.srcDirs = ['java/src']res.srcDirs = ['java/res']manifest.srcFile 'java/AndroidManifest.xml'}
}externalNativeBuild {cmake {path (project.projectDir.toString() + '/libcxx_helper/CMakeLists.txt')}
}

}

dependencies {
}

下面要添加aliyun的镜像路径，不然会报错误：Android无法正常获取https://dl.google.com/dl/android/maven2/com/…
在这里插入图片描述
apply plugin: ‘com.android.application’
android {
compileSdkVersion 26
defaultConfig {
applicationId “org.opencv.samples.cameracalibration”
minSdkVersion 21
targetSdkVersion 26
versionCode 301
versionName “3.01”
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile(‘proguard-android.txt’), ‘proguard-rules.pro’
}
}
sourceSets {
main {
java.srcDirs = [‘src’]
aidl.srcDirs = [‘src’]
res.srcDirs = [‘res’]
manifest.srcFile ‘AndroidManifest.xml’
}
}
}
buildscript {
repositories {
maven{ url ‘https://maven.aliyun.com/nexus/content/groups/public/’}
maven{ url ‘https://maven.aliyun.com/repository/google’}
maven{ url ‘https://maven.aliyun.com/repository/gradle-plugin’}
maven{ url ‘https://maven.aliyun.com/repository/public’}
maven{ url ‘https://maven.aliyun.com/repository/jcenter’}

}
dependencies {
classpath “com.android.tools.build:gradle:4.2.1”

    // NOTE: Do not place your application dependencies here; they belong// in the individual module build.gradle files
}

}
allprojects {
repositories {
maven{ url ‘https://maven.aliyun.com/nexus/content/groups/public/’}
maven{ url ‘https://maven.aliyun.com/repository/google’}
maven{ url ‘https://maven.aliyun.com/repository/gradle-plugin’}
maven{ url ‘https://maven.aliyun.com/repository/public’}
maven{ url ‘https://maven.aliyun.com/repository/jcenter’}

// google()

// jcenter() // Warning: this repository is going to shut down soon
}
}

dependencies {
//implementation fileTree(dir: ‘libs’, include: [‘*.jar’])
// implementation project(‘:opencv’)
implementation project(path: ‘:libopencv’)
}

在gradle.properties里面要把之前有按照其他人的方法设置了代理（比如别的大学的），需要把代理删掉。不然会报错误：Could not HEAD 'https://maven.aliyun.com/repository/google/com/android/tools/build/gradle/4.2.1/grad
C://user/**/.gradle/gradle.properties文件中检查有没有VPN代理，有的话注释掉
