android4.1用哪个ndk编译,androidstudio中用ndk编译的问题

news 来源：原创 2024/5/18 21:43:36

我在Ubuntu上将已编译好的ffmpeg放入我的androidstudio工程，配置OK后，为什么他提示

Error:(319, 10) fatal error: 'libavcodec/avcodec.h' file not found

而同样的我在cmd里，进入到项止jni目录,用ndk-build直接编译就不会出现这个问题,求大神指点

这是我gradle的代码

apply plugin: 'com.android.application'

android {

compileSdkVersion 25

buildToolsVersion "25.0.0"

defaultConfig {

applicationId "com.zyt.vm.lp"

minSdkVersion 10

targetSdkVersion 25

versionCode 1

versionName "1.0"

testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

}

buildTypes {

release {

minifyEnabled false

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

}

debug {

debuggable true

jniDebuggable true

}

sourceSets.main {

jni.srcDirs = [] // This prevents the auto generation of Android.mk

jniLibs.srcDir 'src/main/libs' // This is not necessary unless you have precompiled libraries in your project.

//jniLibs.srcDirs = ['src/main/libs','src/main/jniLibs']

}

externalNativeBuild{

ndkBuild{

path file('src\\main\\jni\\Android.mk')

}

task buildNative(type: Exec, description: 'Compile JNI source via NDK') {

def ndkDir = android.ndkDirectory

commandLine "$ndkDir/ndk-build.cmd",

'-C', file('src/main/jni').absolutePath, // Change src/main/jni the relative path to your jni source

'-j', Runtime.runtime.availableProcessors(),

'all',

'NDK_DEBUG=1',

'NDK_LOG=1'

}

task cleanNative(type: Exec, description: 'Clean JNI object files') {

def ndkDir = android.ndkDirectory

commandLine "$ndkDir/ndk-build.cmd",

'-C', file('src/main/jni').absolutePath, // Change src/main/jni the relative path to your jni source

'clean'

}

clean.dependsOn 'cleanNative'

tasks.withType(JavaCompile) {

compileTask -> compileTask.dependsOn buildNative

}

dependencies {

compile fileTree(include: ['*.jar'], dir: 'libs')

androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {

exclude group: 'com.android.support', module: 'support-annotations'

})

compile 'com.android.support:appcompat-v7:25.0.0'

testCompile 'junit:junit:4.12'

}

编译好的几个库大体都是这样写的
