Method Detail

onStarted

void onStarted()

Indicates that the process of fetching bytes from an InputStream has started.

onProgress

void onProgress(long bytesFetched)

Indicates that the process of fetching bytes from an InputStream has progressed.

The progress will only be reported if the DataFetcher is capable of monitoring the progress.

Parameters:

bytesFetched - Total amount of bytes fetched so far.

onSuccedded

void onSuccedded(Long bytesFetched)

Indicates that the process of fetching bytes from an InputStream has succeeded.

Parameters:

bytesFetched - Total total amount of bytes fetched or null, if the DataFetcher is not capable of monitoring the progress.

onFailed

void onFailed(DataFetchException exception,
              Long bytesFetched)

Indicates that the process of fetching bytes from an InputStream has failed.

Parameters:

exception - The DataFetchException that caused the process to fail. This is the same DataFetchException that is thrown in the failing method of DataFetcher that this DataFetchProgressListener has been given to.

bytesFetched - Total total amount of bytes fetched before the process failed or null, if the DataFetcher is not capable of monitoring the progress.

onFinished

void onFinished()

Indicates that the process of fetching bytes from an InputStream has finished.

This method will be called after either onSuccedded(Long) or onFailed(DataFetchException, Long) has been called.
