Android-HttpDownloadManager
===========================

An useful and effective http download manager for Android. This download manager is designed according to the idea and implementation of Volley.

Usage
=====
* If you don't set the destination file path, the download manager will use `Environment.DIRECTORY_DOWNLOADS` in SDCard as default directory:

>     DownloadManager manager = new DownloadManager();
>     String destPath = Environment.getExternalStorageDirectory() + 
>     				File.separator + "test.apk";
>     DownloadRequest request = new DownloadRequest()
>     		.setDownloadId(downloadId)
>     		.setUrl("http://xxx....")
>     		.setDestFilePath(destPath)
>     		.setDownloadCallback(new DownloadCallback() {
>     				@Override
> 					public void onStart(int downloadId, long totalBytes) {
> 					}
> 
> 					@Override
> 					public void onRetry(int downloadId) {
> 					}
> 
> 					@Override
> 					public void onProgress(int downloadId, long bytesWritten, long totalBytes) {
> 					}
> 
> 					@Override
> 					public void onSuccess(int downloadId, String filePath) {
> 					}
> 
> 					@Override
> 					public void onFailure(int downloadId, int statusCode, String errMsg) {
> 					});
> 					
>     manager.add(request);

* If you don't want to set the filename but want to set the download directory, then you can use `setDestDirectory(String dir)`, but this method will be ignored if `setDestFilePath(String filePath)` was used.
* You can also set retry time with method `setRetryTime(int retryTime)` if necessary, default retry time is 1.
* This manager support downloading in different network type with method `setAllowedNetworkTypes(Context context, int types)`, the types can be `DownloadRequest.NETWORK_MOBILE` and `DownloadRequest.NETWORK_WIFI`. This method need *android.permission.ACCESS_NETWORK_STATE* permission.
* The thread pool size of download manager is 3 by default. If you need a larger pool, then you can create download manager like this: `DownloadManager manager = new DownloadManager(5);`.
* You need *android.permission.WRITE_EXTERNAL_STORAGE* permission if you don't use public directory in SDCard as download destination file path. Don't forget to add *android.permission.INTERNET* permission.
* This download manager support breakpoint downloading, so you can restart the downloading after pause.
* If you don't want DownloadDispathcer invoke `onProgress(int downloadId, long bytesWritten, long totalBytes)` frequently, then you can use `setProgressInterval(int millisec)`.
