Class AndroidHttpClient

java.lang.Object

com.google.android.vending.expansion.downloader.impl.AndroidHttpClient

All Implemented Interfaces:

org.apache.http.client.HttpClient

public final class AndroidHttpClient
extends Object
implements org.apache.http.client.HttpClient

Subclass of the Apache DefaultHttpClient that is configured with reasonable default settings and registered schemes for Android, and also lets the user add HttpRequestInterceptor classes. Don't create this directly, use the newInstance(java.lang.String, android.content.Context) factory method.

This client processes cookies but does not retain them by default. To retain cookies, simply add a cookie store to the HttpContext:

context.setAttribute(ClientContext.COOKIE_STORE, cookieStore);

Method Detail

newInstance

public static AndroidHttpClient newInstance(String userAgent,
                            android.content.Context context)

Create a new HttpClient with reasonable defaults (which you can update).

Parameters:

userAgent - to report in your HTTP requests

context - to use for caching SSL sessions (may be null for no caching)

Returns:

AndroidHttpClient for you to use for all your requests.

newInstance

public static AndroidHttpClient newInstance(String userAgent)

Create a new HttpClient with reasonable defaults (which you can update).

Parameters:

userAgent - to report in your HTTP requests.

Returns:

AndroidHttpClient for you to use for all your requests.

finalize

protected void finalize()
                 throws Throwable

Overrides:

finalize in class Object

Throws:

Throwable

modifyRequestToAcceptGzipResponse

public static void modifyRequestToAcceptGzipResponse(org.apache.http.HttpRequest request)

Modifies a request to indicate to the server that we would like a gzipped response. (Uses the "Accept-Encoding" HTTP header.)

Parameters:

request - the request to modify

See Also:

getUngzippedContent(org.apache.http.HttpEntity)

getUngzippedContent

public static InputStream getUngzippedContent(org.apache.http.HttpEntity entity)
                                       throws IOException

Gets the input stream from a response entity. If the entity is gzipped then this will get a stream over the uncompressed data.

Parameters:

entity - the entity whose content should be read

Returns:

the input stream to read from

Throws:

IOException

close
