DefaultHttpDataSource

public class DefaultHttpDataSource extends BaseDataSource implements HttpDataSource

java.lang.Object
   ↳ androidx.media3.datasource.BaseDataSource
     ↳ androidx.media3.datasource.DefaultHttpDataSource

An HttpDataSource that uses Android's HttpURLConnection.

By default this implementation will not follow cross-protocol redirects (i.e. redirects from HTTP to HTTPS or vice versa). Cross-protocol redirects can be enabled by passing true to setAllowCrossProtocolRedirects.

Note: HTTP request headers will be set using all parameters passed via (in order of decreasing priority) the dataSpec, setRequestProperty and the default properties that can be passed to setDefaultRequestProperties.

Public fields

responseCode

public int responseCode

Public methods

clearAllRequestProperties

@UnstableApi
public void clearAllRequestProperties()

Clears all request headers that were set by setRequestProperty.

clearRequestProperty

@UnstableApi
public void clearRequestProperty(String name)

Clears the value of a request header. The change will apply to subsequent connections established by the source.

Parameters
String name

The name of the header field.

close

@UnstableApi
public void close()

Closes the source. This method must be called even if the corresponding call to open threw an IOException.

Throws
java.io.IOException

If an error occurs closing the source.
androidx.media3.datasource.HttpDataSource.HttpDataSourceException

getResponseCode

@UnstableApi
public int getResponseCode()

When the source is open, returns the HTTP response status code associated with the last open call. Otherwise, returns a negative value.

getResponseHeaders

@UnstableApi
public Map<String, List<String>> getResponseHeaders()

When the source is open, returns the response headers associated with the last open call. Otherwise, returns an empty map.

Key look-up in the returned map is case-insensitive.

getUri

@UnstableApi
public @Nullable Uri getUri()

When the source is open, returns the Uri from which data is being read. The returned Uri will be identical to the one passed open in the DataSpec unless redirection has occurred. If redirection has occurred, the Uri after redirection is returned.

Returns
@Nullable Uri

The Uri from which data is being read, or null if the source is not open.

open

@UnstableApi
public long open(DataSpec dataSpec)

Opens the source to read the specified data.

Throws
androidx.media3.datasource.HttpDataSource.HttpDataSourceException

read

@UnstableApi
public int read(byte[] buffer, int offset, int length)

Reads up to length bytes of data from the input.

If readLength is zero then 0 is returned. Otherwise, if no data is available because the end of the opened range has been reached, then RESULT_END_OF_INPUT is returned. Otherwise, the call will block until at least one byte of data has been read and the number of bytes read is returned.

Parameters
byte[] buffer

A target array into which data should be written.
int offset

The offset into the target array at which to write.
int length

The maximum number of bytes to read from the input.
Returns
int

The number of bytes read, or RESULT_END_OF_INPUT if the input has ended. This may be less than length because the end of the input (or available data) was reached, the method was interrupted, or the operation was aborted early for another reason.
Throws
java.io.IOException

If an error occurs reading from the input.
androidx.media3.datasource.HttpDataSource.HttpDataSourceException

setRequestProperty

@UnstableApi
public void setRequestProperty(String name, String value)

Sets the value of a request header. The value will be used for subsequent connections established by the source.

Note: If the same header is set as a default parameter in the Factory, then the header value set with this method should be preferred when connecting with the data source. See open.

Parameters
String name

The name of the header field.
String value

The value of the field.
