### Inherited methods

From [androidx.media3.datasource.DataSource.Factory](https://developer.android.com/reference/androidx/media3/datasource/DataSource.Factory) `abstract https://developer.android.com/reference/androidx/media3/datasource/DataSource` `@https://developer.android.com/reference/androidx/media3/common/util/UnstableApi
https://developer.android.com/reference/androidx/media3/datasource/DataSource.Factory#createDataSource()()`

Creates a `https://developer.android.com/reference/androidx/media3/datasource/DataSource` instance.

## Public constructors

### Factory

```
public Factory(HttpEngine httpEngine, Executor executor)
```

Creates an instance.

| Parameters |
|---|---|
| `https://developer.android.com/reference/android/net/http/HttpEngine.html httpEngine` | An `https://developer.android.com/reference/android/net/http/HttpEngine.html` to make the requests. |
| `https://developer.android.com/reference/java/util/concurrent/Executor.html executor` | The `https://developer.android.com/reference/java/util/concurrent/Executor.html` that will handle responses. This may be a direct executor (i.e. executes tasks on the calling thread) in order to avoid a thread hop from HttpEngine's internal network thread to the response handling thread. However, to avoid slowing down overall network performance, care must be taken to make sure response handling is a fast operation when using a direct executor. |

## Public methods

### createDataSource

```
@UnstableApi
public HttpDataSource createDataSource()
```

Creates a `https://developer.android.com/reference/androidx/media3/datasource/DataSource` instance.

### setConnectionTimeoutMs

```
@CanIgnoreReturnValue
@UnstableApi
public HttpEngineDataSource.Factory setConnectionTimeoutMs(int connectTimeoutMs)
```

Sets the connect timeout, in milliseconds.

The default is `https://developer.android.com/reference/androidx/media3/datasource/HttpEngineDataSource#DEFAULT_CONNECT_TIMEOUT_MILLIS()`.

| Parameters |
|---|---|
| `int connectTimeoutMs` | The connect timeout, in milliseconds, that will be used. |

| Returns |
|---|---|
| `https://developer.android.com/reference/androidx/media3/datasource/HttpEngineDataSource.Factory` | This factory. |

### setContentTypePredicate

```
@CanIgnoreReturnValue
@UnstableApi
public HttpEngineDataSource.Factory setContentTypePredicate(
    @Nullable Predicate<String> contentTypePredicate
)
```

Sets a content type `https://guava.dev/releases/snapshot-android/api/docs/com/google/common/base/Predicate.html`. If a content type is rejected by the predicate then a `https://developer.android.com/reference/androidx/media3/datasource/HttpDataSource.InvalidContentTypeException` is thrown from `https://developer.android.com/reference/androidx/media3/datasource/HttpEngineDataSource#open(androidx.media3.datasource.DataSpec)`.

The default is `null`.

| Parameters |
|---|---|
| `@https://developer.android.com/reference/androidx/annotation/Nullable https://guava.dev/releases/snapshot-android/api/docs/com/google/common/base/Predicate.html<https://developer.android.com/reference/java/lang/String.html> contentTypePredicate` | The content type `https://guava.dev/releases/snapshot-android/api/docs/com/google/common/base/Predicate.html`, or `null` to clear a predicate that was previously set. |

| Returns |
|---|---|
| `https://developer.android.com/reference/androidx/media3/datasource/HttpEngineDataSource.Factory` | This factory. |

### setDefaultRequestProperties

```
@CanIgnoreReturnValue
@UnstableApi
public final HttpEngineDataSource.Factory setDefaultRequestProperties(
    Map<String, String> defaultRequestProperties
)
```

Sets the default request headers for `https://developer.android.com/reference/androidx/media3/datasource/HttpDataSource` instances created by the factory.

The new request properties will be used for future requests made by `https://developer.android.com/reference/androidx/media3/datasource/HttpDataSource` created by the factory, including instances that have already been created. Modifying the `defaultRequestProperties` map after a call to this method will have no effect, and so it's necessary to call this method again each time the request properties need to be updated.

| Parameters |
|---|---|
| `https://developer.android.com/reference/java/util/Map.html<https://developer.android.com/reference/java/lang/String.html, https://developer.android.com/reference/java/lang/String.html> defaultRequestProperties` | The default request properties. |

| Returns |
|---|---|
| `https://developer.android.com/reference/androidx/media3/datasource/HttpEngineDataSource.Factory` | This factory. |

### setHandleSetCookieRequests

```
@CanIgnoreReturnValue
@UnstableApi
public HttpEngineDataSource.Factory setHandleSetCookieRequests(boolean handleSetCookieRequests)
```

Sets whether "Set-Cookie" requests on redirect should be forwarded to the redirect url in the "Cookie" header.

The default is `false`.

| Parameters |
|---|---|
| `boolean handleSetCookieRequests` | Whether "Set-Cookie" requests on redirect should be forwarded to the redirect url in the "Cookie" header. |

| Returns |
|---|---|
| `https://developer.android.com/reference/androidx/media3/datasource/HttpEngineDataSource.Factory` | This factory. |

### setKeepPostFor302Redirects

```
@CanIgnoreReturnValue
@UnstableApi
public HttpEngineDataSource.Factory setKeepPostFor302Redirects(boolean keepPostFor302Redirects)
```

Sets whether we should keep the POST method and body when we have HTTP 302 redirects for a POST request.

### setReadTimeoutMs

```
@CanIgnoreReturnValue

```

Sets the read timeout, in milliseconds.

The default is `https://developer.android.com/reference/androidx/media3/datasource/HttpEngineDataSource#DEFAULT_READ_TIMEOUT_MILLIS()`.

| Parameters |
|---|---|
| `int readTimeoutMs` | The connect timeout, in milliseconds, that will be used. |

| Returns |
|---|---|
| `https://developer.android.com/reference/androidx/media3/datasource/HttpEngineDataSource.Factory` | This factory. |

### setRequestPriority

```
@CanIgnoreReturnValue
@UnstableApi
public HttpEngineDataSource.Factory setRequestPriority(int requestPriority)
```

Sets the priority of requests made by `https://developer.android.com/reference/androidx/media3/datasource/HttpEngineDataSource` instances created by this factory.

The default is `https://developer.android.com/reference/android/net/http/UrlRequest.html#REQUEST_PRIORITY_MEDIUM`.

| Parameters |
|---|---|
| `int requestPriority` | The request priority, which should be one of HttpEngine's ` UrlRequest#REQUEST_PRIORITY_*` constants. |
