调用已经存在的lib

gradle

只需要在build.gradle

plugins {
    id 'com.android.application'
}

android {
    namespace 'com.example.challengemobile'
    compileSdk 33

    defaultConfig {
        applicationId "com.example.challengemobile"
        minSdk 28
        targetSdk 33
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    sourceSets {
        main {//只需要寫入這個即可
            jniLibs.srcDirs = ['libs']
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    ndkVersion '21.3.6528147'

}
