Android AWS S3 SDK TransferUtility在服务中不起作用

概述我正在尝试在已启动的服务中使用AWSAndroidSDKforS3.我对SDK和服务都不熟悉.我非常有信心TransferUtility也在运行服务.Handler(android.os.Handler){11629d87}sendingmessagetoaHandleronadeadthreadjava.lang.IllegalStateException:Handler(android.os

我正在尝试在已启动的服务中使用AWS Android SDK for S3.我对SDK和服务都不熟悉.我非常有信心Transfer Utility也在运行服务.

Handler (androID.os.Handler) {11629d87} sending message to a Handler on a dead thread    java.lang.IllegalStateException: Handler (androID.os.Handler) {11629d87} sending message to a Handler on a dead thread    at androID.os.MessageQueue.enqueueMessage(MessageQueue.java:325)    at androID.os.Handler.enqueueMessage(Handler.java:631)    at androID.os.Handler.sendMessageAtTime(Handler.java:600)    at androID.os.Handler.sendMessageDelayed(Handler.java:570)    at sksDoneLater(TransferService.java:189)    at com.amazonaws.mobileconnectors.s3.transferutility.TransferService.access0(TransferService.java:44)    at com.amazonaws.mobileconnectors.s3.transferutility.TransferService.handleMessage(TransferService.java:166)    at androID.os.Handler.dispatchMessage(Handler.java:98)    at androID.os.Looper.loop(Looper.java:135)    at androID.os.HandlerThread.run(HandlerThread.java:61)

这是我用来启动它的代码：

    AmazonS3 amazonS3 = new AmazonS3ClIEnt(credentialsProvIDer);    mTransferUtility = new TransferUtility(amazonS3, getApplicationContext());    TransferObserver observer = mTransferUtility.upload(            S3_RAW_BUCKET_ARN,            mVIDfileKey,            mVIDfile);    observer.setTransferListener(new TransferListener() {...})

之前它说它无法获得s3客户端.我在上面的应用程序类中创建了客户端,并成功地在一个活动中使用相同的代码来执行成功的传输,因此它必须是我不知道的服务的显而易见的东西.上面的代码在一个从服务中的onStartCommand()调用的方法中调用.

任何帮助将非常感激.

解决方法:

我发现自己处于同样的问题……
这就是为我解决的问题：

我注意到我在Manifest中注册的SyncAdapter有以下服务：

        <service        androID:name=".sync.SyncService"        androID:exported="true"        androID:process=":sync">        <intent-filter>            <action androID:name="androID.content.SyncAdapter"/>        </intent-filter>        <Meta-data androID:name="androID.content.SyncAdapter"            androID:resource="@xml/syncadapter" />    </service>

androID：process =“：sync”告诉服务在名为：sync的私有进程中运行
所以我只是告诉Amazon SDK的TransferService在同一个线程中运行.

        <service        androID:name="com.amazonaws.mobileconnectors.s3.transferutility.TransferService"        androID:process=":sync"        androID:enabled="true" />

在那之后,我没有得到错误TransferService无法获得s3客户端,它将停止,最后能够将我的图片上传到S3
