工程配置

导入包

• 直接把.jar文件放入app-libs文件夹中，点击Sync Project with Gradle Files
• build.gradle中的依赖方法中加入导入包名，如下

  dependencies {
      implementation fileTree(dir: 'libs', include: ['*.jar'])
      implementation 'com.android.support:appcompat-v7:28.0.0'
      implementation 'com.android.support.constraint:constraint-layout:1.1.3'
      implementation 'com.android.support:design:28.0.0'
      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'
  }
  

  编辑之后点击sync now
