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.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.access$200(TransferService.java:44)
at com.amazonaws.mobileconnectors.s3.transferutility.TransferService$2.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)
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() {...})
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.
Any help would be much appreciated.
UPDATE - Whole Class was requested and is shown here:
public class VideoCompressionService extends Service {;
private Bus bus;
private TransferUtility mTransferUtility;

I found myself in the same issue... Here it is what solved for me:
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>
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" />
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

You should declare the client as a global variable, as the garbage collector could delete it if you don't do it.
