我下载文件的代码如下

RNFetchBlob.config({
    path : path,
    background: true,
    cacheable:false,
    timeout: 1000 * 60 * 15 //15 minutes
})
.fetch('GET', forFile.url, {//some headers ..})
.then((res) => {
    Realm.open({
        schema: [
            ScheduleSchema,
            PlaylistSchema,
            FileSchema
        ],
        schemaVersion: schema_version
    }).then(realm => {
        realm.write(() => {
            localPath = Platform.OS === 'android' ? 'file://' + res.path() : `playlists/${playlistName}/${getFileName(forFile)}`
            forFile.file_local_path = localPath
            console.log('The file saved to ', res.path() + 'for remote url' +forFile.url)

        })
    }).catch((error) => {
        alert("realm open error on file download service", error);
        console.log(error);
        reject(error)
    })
    resolve(forFile);
}).catch((error)=>{
    console.log("file download error " + error);
    showToastMessage(I18n.t("ErrorMessage.ErrorInFileDownload"))
})

此代码适用于 Android 7，但不适用于 Android 9。
