            httpDataSourceFactory = new DefaultHttpDataSource.Factory();
        }
    }
    return httpDataSourceFactory;

Example 2 with CronetEngine

use of org.chromium.net.CronetEngine in project ExoPlayer by google.

the class CronetDataSourceFactory method createDataSourceInternal.

@Override
protected HttpDataSource createDataSourceInternal(HttpDataSource.RequestProperties defaultRequestProperties) {
    @Nullable CronetEngine cronetEngine = cronetEngineWrapper.getCronetEngine();
    if (cronetEngine == null) {
        return fallbackFactory.createDataSource();
    }
    CronetDataSource dataSource = new CronetDataSource(cronetEngine, executor, REQUEST_PRIORITY_MEDIUM, connectTimeoutMs, readTimeoutMs, resetTimeoutOnRedirects, /* handleSetCookieRequests= */

    null, /* keepPostFor302Redirects */
    false);
    if (transferListener != null) {
        dataSource.addTransferListener(transferListener);
    }
    return dataSource;
}

Example 3 with CronetEngine

use of org.chromium.net.CronetEngine in project ExoPlayer by google.

the class CronetDataSourceContractTest method createDataSource.

@Override
protected DataSource createDataSource() {
    @Nullable CronetEngine cronetEngine = CronetUtil.buildCronetEngine(ApplicationProvider.getApplicationContext(), /* userAgent= */
    "test-agent", /* preferGMSCoreCronet= */
    false);
    assertThat(cronetEngine).isNotNull();
    return new CronetDataSource.Factory(cronetEngine, executorService).createDataSource();
}

Example 4 with CronetEngine

use of org.chromium.net.CronetEngine in project ExoPlayer by google.

the class CronetUtil method buildCronetEngine.

/**
 * Builds a {@link CronetEngine} suitable for use with {@link CronetDataSource}. When choosing a
 * {@link CronetProvider Cronet provider} to build the {@link CronetEngine}, disabled providers
 * are not considered. Neither are fallback providers, since it's more efficient to use {@link
 * DefaultHttpDataSource} than it is to use {@link CronetDataSource} with a fallback {@link
 * CronetEngine}.
 *
 * <p>Note that it's recommended for applications to create only one instance of {@link
 * CronetEngine}, so if your application already has an instance for performing other networking,
 * then that instance should be used and calling this method is unnecessary. See the <a
 * href="https://developer.android.com/guide/topics/connectivity/cronet/start">Android developer
 * guide</a> to learn more about using Cronet for network operations.
 *
 * @param context A context.
 * @param userAgent A default user agent, or {@code null} to use a default user agent of the
 *     {@link CronetEngine}.
 * @param preferGooglePlayServices Whether Cronet from Google Play Services should be preferred
 *     over Cronet Embedded, if both are available.
 * @return The {@link CronetEngine}, or {@code null} if no suitable engine could be built.
