Obtains new FileAsyncHttpResponseHandler against context with target being temporary file

参数:

context - Context, must not be null

方法详细资料

deleteTargetFile

public boolean deleteTargetFile()

Attempts to delete file with stored response

返回:

false if the file does not exist or is null, true if it was successfully deleted

getTemporaryFile

protected java.io.File getTemporaryFile(android.content.Context context)

Used when there is no file to be used when calling constructor

参数:

context - Context, must not be null

返回:

temporary file or null if creating file failed

getTargetFile

protected java.io.File getTargetFile()

Retrieves File object in which the response is stored

返回:

File file in which the response is stored

onFailure

public final void onFailure(int statusCode,
                            Header[] headers,
                            byte[] responseBytes,
                            java.lang.Throwable throwable)

从类复制的说明: AsyncHttpResponseHandler

Fired when a request fails to complete, override to handle in your own code

指定者:

onFailure 在类中 AsyncHttpResponseHandler

参数:

statusCode - return HTTP status code

headers - return headers, if any
