老师,为什么最后在module/build.gradle中编译了之后,native的sayhello方法还是报错没有关联头文件,用的as3.0.0
在jni目录下创建Android.mk文件,在module/build.gradle中关联配置,如下
module/build.gradle的内容
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
defaultConfig {
applicationId "com.example.sun.jnidemo"
minSdkVersion 15
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
ndk{
abiFilters "armeabi","armeabi-v7a"
}
}
externalNativeBuild{
ndkBuild{
path "src/main/jni/Android.mk"
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}Android.mk文件的内容
LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_MODULE := hello LOCAL_SRC_FILES := Hello.cpp # for logging LOCAL_LDLIBS += -llog include $(BUILD_SHARED_LIBRARY)
