Answer 1

在默认配置中添加multiDexEnabled true，然后尝试。

defaultConfig {
        applicationId "com.baclock"
        minSdkVersion 16
        targetSdkVersion 23
        versionCode 18
        versionName "2018.02.09"
        multiDexEnabled true
    }

Answer 2

在defaultConfig块中添加multiDexEnabled = true。

defaultConfig {
        applicationId "com.baclock"
        minSdkVersion 16
        targetSdkVersion 23
        versionCode 18
        versionName "2018.02.09"
        multiDexEnabled true
    }
