File Transfer plugin image download get corrupted

Ionic Framework ionic-v3
1

Hi,
I am using file transfer plugin to download images in my app. There are many images to be downloaded.
In iOS the images are fine, but in android tablets the images get corrupted after download and is fine in android phones.

async downloadtabletimages(article_tablet , id){
	try {
    	const fileTransfer: FileTransferObject = this.pdfDownload.create();
    	const url = article_tablet;
    	const target = this.file.dataDirectory + "article_mobile" + id + '.jpg';
    	await fileTransfer.download(url,target).then((location) => {
    		this.database.executeSql('INSERT INTO Article_tablet VALUES(?,?)', [ id  , JSON.stringify(location.nativeURL)]);
    	});
  	} catch (error) {
  	}     	
}

This is my code to download images.
Any suggestions are appreciable.

Thanks.
