Description:

install apk

install_plugin #



A flutter plugin for install apk for android; and using url to go to app store for iOS.
Usage #
To use this plugin, add install_plugin as a dependency in your pubspec.yaml file.
/// for Android : install apk by its file absolute path;
/// if the target platform is higher than android 24:
/// a [appId] is required
/// (the caller's applicationId which is defined in build.gradle)
static Future<String> installApk(String filePath, String appId) async {
Map<String, String> params = {'filePath': filePath, 'appId': appId};
return await _channel.invokeMethod('installApk', params);
}

/// for iOS: go to app store by the url
static Future<String> gotoAppStore(String urlString) async {
Map<String, String> params = {'urlString': urlString};
return await _channel.invokeMethod('gotoAppStore', params);

Example #
For Android, you may need to request permission for READ_EXTERNAL_STORAGE to read the apk file. In the example, I used the permission_handler plugin.
import 'dart:async';

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:install_plugin/install_plugin.dart';
import 'package:permission_handler/permission_handler.dart';

void main() => runApp(new MyApp());

class MyApp extends StatefulWidget {
@override
_MyAppState createState() => new _MyAppState();
}

class _MyAppState extends State<MyApp> {
String _appUrl = '';
String _apkFilePath = '';

@override
Widget build(BuildContext context) {
return new MaterialApp(
home: new Scaffold(
appBar: new AppBar(
title: const Text('Plugin example app'),
),
body: new Column(
children: <Widget>[
TextField(
decoration: InputDecoration(
hintText:
'apk file path to install. Like /storage/emulated/0/demo/update.apk'),
onChanged: (path) => _apkFilePath = path,
),
FlatButton(
onPressed: () {
onClickInstallApk();
},
child: Text('install')),
TextField(
decoration:
InputDecoration(hintText: 'URL for app store to launch'),
onChanged: (url) => _appUrl = url,
),
FlatButton(
onPressed: () => onClickGotoAppStore(_appUrl),
child: Text('gotoAppStore'))
],
),
),
);
}

void onClickInstallApk() async {
if (_apkFilePath.isEmpty) {
print('make sure the apk file is set');
return;
}
Map<PermissionGroup, PermissionStatus> permissions =
await PermissionHandler().requestPermissions([PermissionGroup.storage]);
if (permissions[PermissionGroup.storage] == PermissionStatus.granted) {
InstallPlugin.installApk(_apkFilePath, 'com.zaihui.installpluginexample')
.then((result) {
print('install apk $result');
}).catchError((error) {
print('install apk error: $error');
});
} else {
print('Permission request fail!');
}
}

void onClickGotoAppStore(String url) {
url = url.isEmpty
? 'https://itunes.apple.com/cn/app/%E5%86%8D%E6%83%A0%E5%90%88%E4%BC%99%E4%BA%BA/id1375433239?l=zh&ls=1&mt=8'
: url;
InstallPlugin.gotoAppStore(url);
}
}
