android studio 加载jni调试

1、在主工程的local.properties中添加ndk信息，如
## This file must *NOT* be checked into Version Control Systems,
# as it contains information specific to your local configuration.
#
# Location of the SDK. This is only used by Gradle.
# For customization when using a Version Control System, please read the
# header note.

ndk.dir=C\:\\android-ndk-r13b\\android-ndk-r13b//该行代码与JNI有关系
sdk.dir=C\:\\Users\\Admin\\AppData\\Local\\Android\\Sdk

2、在子工程的**\build.gradle修改
apply plugin: 'com.android.library'

android {
    compileSdkVersion rootProject.ext.androidCompileSdkVersion
    buildToolsVersion rootProject.ext.androidBuildToolsVersion

    defaultConfig {
        minSdkVersion rootProject.ext.minSdkVersion

        versionName rootProject.ext.releaseVersionName

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        consumerProguardFiles 'consumer-rules.pro'

//JNI 相关 begin
        ndk {
            //abiFilters "armeabi-v7a","arm64-v8a","armeabi"
            abiFilters "armeabi-v7a"
        }

        externalNativeBuild {
            ndkBuild {
                targets "imobilevideomediaengineapijava", "cpufeatures", "mbhwengine-audio"
//                arguments "NDK_APPLICATION_MK:=Application.mk"
//                cFlags "-DTEST_C_FLAG1", "-DTEST_C_FLAG2"
//                cppFlags "-DTEST_CPP_FLAG2", "-DTEST_CPP_FLAG2"
//                abiFilters "armeabi-v7a", "armeabi"
            }
        }

//JNI 相关 end

    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
//JNI 相关 begin
    sourceSets {
        main {

            jni.srcDirs = ['src/main/jni', 'src/main/jni/']
        }
    }

    packagingOptions {
        exclude 'lib/armeabi-v7a/libcetc-log.so'
        exclude 'lib/armeabi-v7a/libcetc-media-ffmpeg.so'
        exclude 'lib/armeabi-v7a/libcetc-media-codec.so'
    }

    externalNativeBuild {
        ndkBuild {
            path 'src/main/jni/Android.mk'
        }
    }
//JNI 相关 end
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'androidx.appcompat:appcompat:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.0'

    implementation project(':cameramodule')

    implementation project(':webrtcagc')

    implementation project(':common')

    implementation files('libs/webrtc-apm-release.aar')
