【问题描述】：
在我的应用程序中，我想从服务器获取数据，为了连接到服务器，我使用了 Retrofit、OkHttp。
但是在运行应用程序时，显示强制关闭错误。
在 android api 21+ 中没有错误，但在 api 21 下面显示强制关闭错误。
ApiClient 类代码：
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)
}
}
显示此行的错误：.build() 在此方法上 val client = clientBuilder
我将此代码添加到 gradle.build
compileOptions {
sourceCompatibility = '1.8'
targetCompatibility = '1.8'
}
但再次显示错误！
