1.安装插件
$ ionic plugin add cordova-plugin-file
$ npm install --save @ionic-native/file
$ ionic plugin add cordova-plugin-file-transfer
$ npm install --save @ionic-native/transfer
$ ionic plugin add cordova-plugin-file-opener2

2. app.module.ts声明
import {
File }
from
'@ionic-native/file';
import {
FileOpener }
from
'@ionic-native/file-opener';
import {
Transfer }
from
'@ionic-native/transfer';
import {

useClass:
IonicErrorHandler},
AppVersion,
File,
FileOpener,
Transfer
]
