我已经坚持这个问题2天了,并尝试了stackoverflow上给出的所有可能的解决方案.下面是我的build.gradle文件:
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.3"
sourceSets.main.jni.srcDirs = []
sourceSets.main.jniLibs.srcDir 'src/main/libs'
defaultConfig {
applicationId "com.example.anannyauberoi.testingcam"
minSdkVersion 15
targetSdkVersion 25
versionCode 1
versionName "1.0"
ndk {
moduleName "app"
cFlags "-std=c++11 -fexceptions"
ldLibs "log"
stl "gnustl_shared"
abiFilter "armeabi-v7a"
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
sourceSets { main { jni.srcDirs = []
res.srcDirs = ['src/main/res']
jniLibs.srcDirs=['src/main/libs']
} }
//sourceSets.main.jni.srcDirs = []
// disable automatic ndk-build call, which ignore our Android.mk
task ndkBuild(type: Exec, description: 'Compile JNI source via NDK') {
commandLine "C:/Users/Anannya-Uberoi/AppData/Local/Android/sdk/ndk-bundle/ndk-build.cmd",
'NDK_PROJECT_PATH=build/intermediates/ndk',
'NDK_LIBS_OUT=src/main/jniLibs',
'APP_BUILD_SCRIPT=src/main/jni/Android.mk',
'NDK_APPLICATION_MK=src/main/jni/Application.mk'
}
tasks.withType(JavaCompile) {
compileTask -> compileTask.dependsOn ndkBuild
}
tasks.all { task ->
if (task.name.startsWith('compile') && task.name.endsWith('Ndk')) {
task.enabled = false
}
}
// call regular ndk-build(.cmd) script from app directory
}
//Modify the below set of code to the ndk-build.cmd location in your computer.
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:25.3.1'
compile project(':openCVLibrary249')
}
我已经尝试了所有可能的解决方案 – 删除build文件夹中的obj文件夹,尝试通过设置sourceSets.main来避免自动Android.mk调用,试图避免调用compileDebugNdk任务.我也没有任何cmake.txt文件.我似乎无法克服这个问题.
我使用过Android Studio 2.3.2和2.1.1,这两个问题都存在.
任何帮助,将不胜感激.
最佳答案 你应该使用最新的Android Studio,2.3.2就行了.它在android gradle插件中集成了externalNativeBuild,因此您不需要使用自定义gradle任务的技巧.
我实际上无法测试下面的build.gradle脚本,所以请原谅我任何错别字:
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.3"
defaultConfig {
applicationId "com.example.anannyauberoi.testingcam"
minSdkVersion 15
targetSdkVersion 25
versionCode 1
versionName "1.0"
externalNativeBuild {
ndkBuild {
targets "app"
cppFlags "-std=c++11 -fexceptions"
arguments "APP_STL=gnustl_shared"
abiFilters "armeabi-v7a"
}
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
sourceSets { main {
res.srcDirs = ['src/main/res']
} }
externalNativeBuild {
ndkBuild {
path "src/main/jni/Android.mk"
}
}
//Modify the below set of code to the ndk-build.cmd location in your computer.
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:25.3.1'
compile project(':openCVLibrary249')
}
