Question

当我运行旧的android项目时，我得到一条错误消息：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27

    defaultConfig {
        applicationId "com.example.android.firebaseupload"
        minSdkVersion 21
        targetSdkVersion 27

        }
    }

        dependencies {

            implementation fileTree(include: ['*.jar'], dir: 'libs')
            androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {

            testImplementation 'junit:junit:4.12'
