Android AWS S3 SDK TransferUtility不在服务中 [英] Android AWS S3 SDK TransferUtility Not Working in Service
问题描述
我正在尝试在已启动的服务中使用适用于S3的AWS开发工具包.我对SDK和服务都有些陌生.我非常有信心Transfer Utility也正在运行服务.
I am trying to use the AWS Android SDK for S3 in a started service. I am a little new to both the SDK and Services. I am pretty confident that the Transfer Utility is also running a service.
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.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:
Here is the code I am using to start it up:
AmazonS3 amazonS3 = new AmazonS3Client(credentialsProvider);
mTransferUtility = new TransferUtility(amazonS3, getApplicationContext());
TransferObserver observer = mTransferUtility.upload(
S3_RAW_BUCKET_ARN,
mVidFileKey,
mVidFile);
observer.setTransferListener(new TransferListener() {...})
它说不能获得s3客户端的前一行.我按照上面在应用程序类中所示创建了客户端，并成功地在活动中使用了相同的代码来执行成功的传输，因此对于我不了解的服务，它一定是显而易见的.在服务中从onStartCommand()调用的方法中调用了上面的代码.
The line previous it says it can't get s3 client. I created the client just as shown above in application class and successfully used the same code in an activity to perform a successful transfer so it must be something obvious about services that I am ignorant of. The above code is called in a method that is called from onStartCommand() in the service.
任何帮助将不胜感激.

推荐答案
我发现自己也遇到了同样的问题... 这就是为我解决的问题:
I found myself in the same issue... Here it is what solved for me:
我注意到我在清单中注册了SyncAdapter的以下服务:
I noticed I had the following service for my SyncAdapter registered in Manifest:
<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 因此，我只是告诉Amazon SDK中的TransferService可以在同一线程中运行.
The android:process=":sync" tells service to run in a private process called :sync So I just told the TransferService from Amazon SDK to run in this same thread.
<service
android:name="com.amazonaws.mobileconnectors.s3.transferutility.TransferService"
android:process=":sync"
android:enabled="true" />
此后，我再也没有出现错误 TransferService无法获取s3客户端，它将停止，最后终于可以将我的图片上传到S3
After that, I no more got the error TransferService can't get s3 client, and it will stop, and finally was able to upload my pictures to S3
