How to cancel the task when cut off network

[zhujunhua2012]

State your question
I want to treat TransferState.WAITING_FOR_NETWORK as a final state, like failed.

final TransferObserver observer = transferUtility.download(filePath, myOutfile);
observer.setTransferListener(new TransferListener() {
    @UiThread
    @Override
    public void onStateChanged(int id, TransferState transferState) {
        // it's on UI thread
        switch (transferState) {
            case WAITING:
            case IN_PROGRESS:
                break;
            case PAUSED:
            case RESUMED_WAITING:
                break;
            case WAITING_FOR_NETWORK:
		// I want to treat this state as a final state
                // after involes cancel, I will not receive CANCELED callback
		transferUtility.cancel(id);
                break;
            case COMPLETED:
            case CANCELED:
            case FAILED:
                break;
            default:
                break;
        }
    }

    @Override
    public void onProgressChanged(int id, long bytesCurrent, long bytesTotal) {
    }

    @Override
    public void onError(int id, Exception e) {
    }
});

In default, it will block when I turn off the internet, WAITING_FOR_NETWORK will be passed in onStateChanged.

But I want to treat this issue as a failed state. I tried like above, transferUtility.cancel(id) when the state becomes to WAITING_FOR_NETWORK, but I can't receive the next state 'CANCELED', anything wrong?

another question, when I turn on the internet, start a new task to download a new file, previous transferObserver will receive a onStateChanged, althoug I canceled it like above. What should I do to cancel the record and task? (and I dont need the previous tasks' callbacks)

thanks!
