Using AWS Android TransferUtility in Service

Question

This includes Android SDK’s in S3. Can I use it  service for a particular set, and transfer listener and use it to send updates to application or create notifications too.

 I know that the TransferUtility lets one create a service for its own use.

Please help!

Answer 1

I am not certain what you is entirely possible, but you can start a service from another service.

When TransferUtility fails to work  its because Amazon S3 client gets garbage collected before TransferService gets it. Now an object is passed as a parcelable between components. But it is complicated to make S3 client parcelable.

Hence the SDK can actually take an alternate route by passing a weak reference of it stored in a static map. The key is that the caller must keep the S3 client alive before TransferService gets it.

Answer 2

Yes it's possible to start a service from another service.

TransferUtility may fail to work if its Amazon S3 client gets garbage collected before TransferService gets it. Normally an object is passed as a parcelable in an intent between components. However it's quite complicated to make S3 client parcelable. So the SDK takes an alternate route by passing a weak reference of it stored in a static map. The key is that the caller must keeps the S3 client alive before TransferService gets it.
