request.setAllowedOverRoaming(false);
//Set the title of this download, to be displayed in notifications (if enabled).
request.setTitle("My Data Download");
//Set a description of this download, to be displayed in notifications (if enabled)
request.setDescription("Android Data download using DownloadManager.");
//Set the local destination for the downloaded file to a path within the application's external files directory
request.setDestinationInExternalFilesDir(this, Environment.DIRECTORY_DOWNLOADS,"20MB.zip");

I was able to implement Pause/Resume functionality using the following implementation via the Android DownloadManager and Downloads Content Provider:
private boolean resumeDownload(Context context, String downloadTitle) {
int updatedRows = 0;
ContentValues resumeDownload = new ContentValues();
resumeDownload.put("control", 0); // Resume Control Value
try {
updatedRows = context
.getContentResolver()
.update(Uri.parse("content://downloads/my_downloads"),
resumeDownload,
"title=?",
new String[]{ downloadTitle });
} catch (Exception e) {
Log.e(TAG, "Failed to update control for downloading video");
}
return 0 < updatedRows;
}
private boolean pauseDownload(Context context, String downloadTitle) {
int updatedRows = 0;
ContentValues pauseDownload = new ContentValues();
pauseDownload.put("control", 1); // Pause Control Value
try {
updatedRows = context
.getContentResolver()
.update(Uri.parse("content://downloads/my_downloads"),
pauseDownload,
"title=?",
new String[]{ downloadTitle });
} catch (Exception e) {
Log.e(TAG, "Failed to update control for downloading video");
}
return 0 < updatedRows;
}
