# Class ExtendedDataSource

java.lang.Object
com.castlabs.android.network.ExtendedDataSource

All Implemented Interfaces:
  `com.google.android.exoplayer2.upstream.DataSource`

public class ExtendedDataSource extends Object implements com.google.android.exoplayer2.upstream.DataSource
A `DataSource` that supports multiple URI schemes. The supported schemes are:

- http(s): For fetching data over HTTP and HTTPS (e.g. https://www.something.com/media.mp4).
- file: For fetching data from a local file (e.g. file:///path/to/media/media.mp4, or just /path/to/media/media.mp4 because the implementation assumes that a URI without a scheme is a local file URI).
- asset: For fetching data from an asset in the application's apk (e.g. asset:///media.mp4).
- content: For fetching data from a content URI (e.g. content://authority/path/123).

Instances of this class also expose the last accessed Uri using `getLastUri()`.

- ## Constructor Details

  - ### ExtendedDataSource

    public ExtendedDataSource(Context context, String userAgent)
    Constructs a new instance.

    The constructed instance will not follow cross-protocol redirects (i.e. redirects from HTTP to HTTPS or vice versa) when fetching remote data. Cross-protocol redirects can be enabled by using `ExtendedDataSource(Context, TransferListener, String, boolean, SSLSocketFactory)` and passing `true` as the final argument.
    Parameters:
      `context` - A context.
      `userAgent` - The User-Agent string that should be used when requesting remote data.

  - ### ExtendedDataSource

    public ExtendedDataSource(Context context, com.google.android.exoplayer2.upstream.TransferListener listener, String userAgent)
    Constructs a new instance.

    The constructed instance will not follow cross-protocol redirects (i.e. redirects from HTTP to HTTPS or vice versa) when fetching remote data. Cross-protocol redirects can be enabled by using `ExtendedDataSource(Context, TransferListener, String, boolean, SSLSocketFactory)` and passing `true` as the final argument.
    Parameters:
      `context` - A context.
      `listener` - An optional `TransferListener`.
      `userAgent` - The User-Agent string that should be used when requesting remote data.

  - ### ExtendedDataSource

    public ExtendedDataSource(Context context, com.google.android.exoplayer2.upstream.TransferListener listener, String userAgent, boolean allowCrossProtocolRedirects, @Nullable SSLSocketFactory sslSocketFactory)
    Constructs a new instance, optionally configured to follow cross-protocol redirects.
    Parameters:
      `context` - A context.
      `listener` - An optional `TransferListener`.
      `userAgent` - The User-Agent string that should be used when requesting remote data.
      `allowCrossProtocolRedirects` - Whether cross-protocol redirects (i.e. redirects from HTTP to HTTPS and vice versa) are enabled when fetching remote data.
      `sslSocketFactory` - The SSL socket factory to use for HTTPS connections

  - ### ExtendedDataSource

    public ExtendedDataSource(Context context, com.google.android.exoplayer2.upstream.TransferListener listener, com.google.android.exoplayer2.upstream.HttpDataSource httpDataSource)
    Constructs a new instance, using a provided `HttpDataSource` for fetching remote data.
    Parameters:
      `context` - A context.
      `listener` - An optional `TransferListener`.
      `httpDataSource` - `DataSource` to use for non-file URIs.

  - ### ExtendedDataSource

    public ExtendedDataSource(Context context, com.google.android.exoplayer2.upstream.TransferListener listener, com.google.android.exoplayer2.upstream.HttpDataSource httpDataSource, @Nullable PlayerController playerController)
    Constructs a new instance, using a provided `HttpDataSource` for fetching remote data.
    Parameters:
      `context` - A context.
      `listener` - An optional `TransferListener`.
      `httpDataSource` - `DataSource` to use for non-file URIs.
      `playerController` - The player controller
