olly 14c46bc406 Remove contentTypePredicate from DataSource constructors
The only known use case for contentTypePredicate is to catch
the case when a paywall web page is returned via a DataSource,
rather than the data that was being requested. These days streaming
providers should be using HTTPS, where this problem does not exist.
Devices have also gotten a lot better at showing their own
notifications when paywalls are detected, which largely mitigates
the need for the app to show a more optimal error message or
redirect the user to a browser.

It therefore makes sense to deprioritize this feature. In
particular by removing the arg from constructors, where nearly
all applications are probably passing null.

ExoPlayer Cronet extension

The Cronet extension is an HttpDataSource implementation using Cronet.

Getting the extension

The easiest way to use the extension is to add it as a gradle dependency:

implementation 'com.google.android.exoplayer:extension-cronet:2.X.X'

where 2.X.X is the version, which must match the version of the ExoPlayer library being used.

Alternatively, you can clone the ExoPlayer repository and depend on the module locally. Instructions for doing this can be found in ExoPlayer's top level README.

Using the extension

ExoPlayer requests data through DataSource instances. These instances are either instantiated and injected from application code, or obtained from instances of DataSource.Factory that are instantiated and injected from application code.

If your application only needs to play http(s) content, using the Cronet extension is as simple as updating any DataSources and DataSource.Factory instantiations in your application code to use CronetDataSource and CronetDataSourceFactory respectively. If your application also needs to play non-http(s) content such as local files, use

new DefaultDataSource(
    ...
    new CronetDataSource(...) /* baseDataSource argument */);

and

new DefaultDataSourceFactory(
    ...
    new CronetDataSourceFactory(...) /* baseDataSourceFactory argument */);

respectively.
