预计方法是虚拟类型(Method was expected to be of type virtual)
我尝试使用以下代码将AWS Mobile Hub示例项目中的AWSMobileClient.defaultMobileClient()初始化为我的测试项目：
if (AWSMobileClient.defaultMobileClient() == null) { Log.e("MainActivity", "Initializing AWS Mobile Client..."); final ClientConfiguration clientConfiguration = new ClientConfiguration(); clientConfiguration.setUserAgent(AWSConfiguration.AWS_MOBILEHUB_USER_AGENT); final IdentityManager identityManager = new IdentityManager(getApplicationContext(), clientConfiguration); final AWSMobileClient awsClient = new AWSMobileClient.Builder(getApplicationContext()) .withCognitoRegion(AWSConfiguration.AMAZON_COGNITO_REGION) .withCognitoIdentityPoolID(AWSConfiguration.AMAZON_COGNITO_IDENTITY_POOL_ID) .withIdentityManager(identityManager) .withClientConfiguration(clientConfiguration) .build(); AWSMobileClient.setDefaultMobileClient(awsClient); }当我在设备中打开应用程序时，我在Android Studio中获得了此错误日志：
