Comment réparer Expected Android API level 21+ mais était de 19 en Android

Dans mon application, je veux obtenir des données du serveur, pour me connecter au serveur, j'ai utilisé Retrofit, OkHttp.
Mais lors de l'exécution de l'application, montrez-moi forcer la fermeture de l'erreur.
Dans Android api 21 + n'est pas une erreur, mais ci-dessous api 21 affichez-moi forcez la fermeture de l'erreur.

codes de classe ApiClient:

class ApiClient constructor(private val deviceUUID: String) {

    private val apiServices: ApiServices

    init {
        //Gson
        val gson = GsonBuilder()
            .setLenient()
            .create()

        //Http log
        val loggingInterceptor = HttpLoggingInterceptor()
        loggingInterceptor.level =
            if (BuildConfig.DEBUG) HttpLoggingInterceptor.Level.BODY else HttpLoggingInterceptor.Level.NONE

        //Http Builder
        val clientBuilder = OkHttpClient.Builder()
        clientBuilder.interceptors().add(loggingInterceptor)
        clientBuilder.addInterceptor { chain ->
            val request = chain.request()
            request.newBuilder().addHeader(AGENT_NAME, AGENT_VALUE).build()
            chain.proceed(request)
        }
        clientBuilder.addInterceptor { chain ->
            val request = chain.request()
            request.newBuilder().addHeader(X_CLIENT_VERSION, APP_VERSION_NAME).build()
            chain.proceed(request)
        }
        clientBuilder.addInterceptor { chain ->
            val request = chain.request()
            request.newBuilder().addHeader(UUID_NAME, deviceUUID).build()
            chain.proceed(request)
        }

        //Http client
        val client = clientBuilder
            .readTimeout(NETWORK_CONNECTIONS_TIME, TimeUnit.SECONDS)
            .writeTimeout(NETWORK_CONNECTIONS_TIME, TimeUnit.SECONDS)
            .connectTimeout(NETWORK_CONNECTIONS_TIME, TimeUnit.SECONDS)
            .retryOnConnectionFailure(true)
            .build()

        //Retrofit
        val retrofit = Retrofit.Builder()
            .baseUrl(BASE_URL)
            .client(client)
            .addConverterFactory(GsonConverterFactory.create(gson))
            .addCallAdapterFactory(RxJava2CallAdapterFactory.createWithScheduler(Schedulers.io()))
            .build()

        //Init apiServices
        apiServices = retrofit.create(ApiServices::class.Java)
    }

    companion object {
        private var apiClient: ApiClient? = null

        fun getInstance(deviceUUID: String): ApiClient =
            apiClient ?: synchronized(this) {
                apiClient ?: ApiClient(deviceUUID).also {
                    apiClient = it
                }
            }
    }

    /**
     * Send apiServices to ApisUseCase for initialize all of apis
     */
    fun apisUseCase(): ApisUseCase {
        return ApisUseCase(apiServices)
    }
}

Montrez-moi une erreur pour cette ligne: .build() sur cette méthode val client = clientBuilder

J'ai ajouté ces codes dans gradle.build

compileOptions {
    sourceCompatibility = '1.8'
    targetCompatibility = '1.8'
}

mais montrez-moi encore une fois l'erreur!

Android 4.4 (fonctionne pour moi)

def ok_http_version = "3.11.0"
implementation "com.squareup.okhttp3:okhttp:$ok_http_version"
implementation "com.squareup.okhttp3:logging-interceptor:$ok_http_version"

Merci @ https://stackoverflow.com/users/5773044/anupam Ce code fonctionne dans Android API 19:

// Note: 3.12.+ to support Android API 19
implementation 'com.squareup.okhttp3:okhttp:3.12.10'
implementation 'com.squareup.okhttp3:logging-interceptor:3.12.10'

implementation 'io.reactivex.rxjava2:rxkotlin:2.4.0'
implementation 'io.reactivex.rxjava2:rxandroid:2.1.1'

implementation 'com.squareup.retrofit2:adapter-rxjava2:2.6.4'
implementation 'com.squareup.retrofit2:converter-gson:2.6.4'
implementation 'com.squareup.retrofit2:converter-scalars:2.6.4'
testImplementation 'com.squareup.retrofit2:retrofit-mock:2.6.4'

Utilisez la version 3.11.0 pour le niveau api inférieur à 21

 implementation 'com.squareup.okhttp3:okhttp:3.11.0'
 implementation 'com.squareup.okhttp3:logging-interceptor:3.11.0'

J'étais confronté au même problème au niveau de l'API 19 lorsque j'ai ajouté ci-dessous dans le fichier build.gradle.

implementation 'com.squareup.okhttp3:okhttp:3.12.2'
implementation 'com.squareup.okhttp3:logging-interceptor:3.13.1'

Enfin, le code ci-dessous m'a aidé à résoudre ce problème:

  implementation 'com.squareup.okhttp3:okhttp:3.11.0'
  implementation 'com.squareup.okhttp3:logging-interceptor:3.5.0'

J'espère que cette solution fonctionne bien pour tous.
