需要在build.gradle檔案中新增如下紅色部分

apply plugin: 'com.android.application'
android {
    compileSdkVersion 27
defaultConfig {
        applicationId "exrobot.lulyfan.ut.com.rosdemo"
minSdkVersion 15
targetSdkVersion 27
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
 
}
    buildTypes {
        release {
            minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
    }
}

repositories {
    flatDir {
        dirs 'libs'
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support.constraint:constraint-layout:1.1.2'
 
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation(name: 'android_10-0.2.0', ext: 'aar')-》其中name是匯入架包的名稱，ext是架包的字尾名
}
