我尝试使用以下代码将我的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中收到了此错误日志:

public class AWSMobileClient {

我真的不明白我面临的问题,你能帮助我吗?
答案 0 :(得分:0)
我已将我的Google Play服务库版本从9.0.0更改为9.0.1并解决了它。
