Method Detail

getBitrateEstimate

public long getBitrateEstimate()

Description copied from interface: BandwidthMeter

Gets the estimated bandwidth, in bits/sec.

Specified by:

getBitrateEstimate in interface BandwidthMeter

Returns:

Estimated bandwidth in bits/sec, or BandwidthMeter.NO_ESTIMATE if no estimate is available.

onTransferStart

public void onTransferStart()

Description copied from interface: TransferListener

Invoked when a transfer starts.

Specified by:

onTransferStart in interface TransferListener

onBytesTransferred

public void onBytesTransferred(int bytes)

Description copied from interface: TransferListener

Called incrementally during a transfer.

Specified by:

onBytesTransferred in interface TransferListener

Parameters:

bytes - The number of bytes transferred since the previous call to this method (or if the first call, since the transfer was started).

onTransferEnd

public void onTransferEnd()

Description copied from interface: TransferListener

Invoked when a transfer ends.

Specified by:

onTransferEnd in interface TransferListener
