[Tip] How to Immediately delete canceled files during download + Android Task.cancel() not working with catch error

[bang9]

Nevertheless you cancel the download task, file is exist exactly in your app caches

this.downloadTask
    .config({
        fileCache : true,
        path : RNFetchBlob.fs.dirs.DocumentDir + `/yourApp/${fileUniqueId}.mp3`
    })
    .fetch('GET', downloadURL, {});

this.downloadTask
    .progress({ interval : 100 }, (received, total) => {
        console.log('progress ' + Math.floor(received/total*100) + '%');
        progressCb(Math.floor(received/total*100))
    })
    .then(async (res)=>{
        console.log("then response",res);
        console.log('The file saved to ', res.path());
        const filePath = 'file://' + res.path();

       //save file path in AsyncStorage
        let saveList = {};
        const downloadList = await AsyncStorage.getItem("@download");
        if(downloadList)
            saveList = JSON.parse(downloadList);
        saveList[contentKey] = filePath;

        return AsyncStorage.setItem("@download",JSON.stringify(saveList))
    })
    .then(()=>{
        finishCb();
    })
    .catch((err)=>{
       //you must add this line. If you don't add, your app users waste they're storage
        RNFetchBlob.fs.unlink(RNFetchBlob.fs.dirs.DocumentDir + `/yourApp/${fileUniqueId}.mp3`);
        console.log(err)
    })
