我正在开发视频压缩应用程序,因此我在运行应用程序时使用NDK并收到错误。 我看到了很多stackOverflow问题(应用程序中的执行错误:buildNative),但stackOverflow解决方案不适用于此错误。
Gradle构建消息:
Gradle tasks [:app:assembleDebug]
:app:buildNative FAILED
Error:Execution failed for task ':app:buildNative'.
> A problem occurred starting process 'command 'null/ndk-build.cmd''
有人帮我解答问题吗?
的build.gradle(模块:应用)
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion '22.0.1'
defaultConfig {
applicationId "com.xxxx.videocompressor"
minSdkVersion 16
targetSdkVersion 22
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_7
targetCompatibility JavaVersion.VERSION_1_7
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
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.
}
task buildNative(type: Exec, description: 'Compile JNI source via NDK') {
def ndkDir = android.ndkDirectory
commandLine "$ndkDir/ndk-build.cmd",
'-C', file('src/main/jni/').absolutePath, // Change src/main/jni the relative path to your jni source
'-j', Runtime.runtime.availableProcessors(),
'all',
'NDK_DEBUG=1'
}
task cleanNative(type: Exec, description: 'Clean JNI object files') {
def ndkDir = android.ndkDirectory
commandLine "$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
}
productFlavors {
}
}
dependencies {
compile 'com.android.support:support-v4:22.2.+'
compile 'com.android.support:support-v4:22.2.+'

答案 0 :(得分:1)
而不是仅使用此
//从app目录中调用常规的ndk-build(.cmd)脚本
task ndkBuild(type: Exec) {
if (Os.isFamily(Os.FAMILY_WINDOWS)) {
commandLine 'ndk-build.cmd', '-C', file('src/main').absolutePath
} else {
commandLine 'ndk-build', '-C', file('src/main').absolutePath
}
}
使用此
//从app目录中调用常规的ndk-build(.cmd)脚本
task ndkBuild(type: Exec) {
if (Os.isFamily(Os.FAMILY_WINDOWS)) {
commandLine 'ndk-build.cmd', '-C', file('src/main').absolutePath
} else {
commandLine 'ndk-build', '-C', file('src/main').absolutePath
}
}
tasks.withType(JavaCompile) {
compileTask -> compileTask.dependsOn ndkBuild
}
