flutter_android_package_installer 0.0.2+3

A Flutter plugin for installing Android package from apk file. Plugin uses Android Package Installer and requires minimum API Level version 21.

flutter_android_package_installer

本库基于android_package_installer改造, 适配最新Flutter 3.24.0版本, 并修改了以下内容:

• 原库的installApk方法调用的是PackageInstaller.Session方法实现的. PackageInstaller 我这里测试就没成功过. 所以这里更改了此方法的默认实现为Intent.ACTION_VIEW
• 原库的installApk方法改名为installApkSession
• 修改compileSdk 34
• 新增getPlatformVersion方法
• 新增openAppMarket方法
• 新增openAppSettingDetail方法

补充一点

FileProvider资源配置需要包含root-path:

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="external_files" path="."/>
    <root-path name="root" path="" />
</paths>

android_package_installer

A Flutter plugin for installing Android package from apk file. Plugin uses Android Package Installer and requires minimum API Level version 21.

Using

import 'package:android_package_installer/android_package_installer.dart';

  int? statusCode = await AndroidPackageInstaller.installApk(apkFilePath: '/sdcard/Download/com.example.apk');
  if (code != null) {
    PackageInstallerStatus installationStatus = PackageInstallerStatus.byCode(statusCode);
    print(installationStatus.name);
  }

To install the Android package the application will need permissions. You can use the permission_handler package to request them.

Setup

1. Add the permissions to your AndroidManifest.xml file in <projectDir>/android/app/src/main/AndroidManifest.xml:
   • android.permission.REQUEST_INSTALL_PACKAGES - required for installing android packages.
   • android.permission.READ_EXTERNAL_STORAGE - required to access the external storage where the apk file is located.

<manifest xmlns:tools="http://schemas.android.com/tools" ...>

  <!-- ADD THESE PERMISSIONS -->
  <uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES"/>
  <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
  
  <application ...>
    <activity ...>

      ...

      <!-- ADD THIS INTENT FILTER -->
      <intent-filter>
        <action
            android:name="com.android_package_installer.content.SESSION_API_PACKAGE_INSTALLED"
            android:exported="false"/>
      </intent-filter>
    </activity>

    <!-- ADD THIS PROVIDER -->
    <provider
      android:name="androidx.core.content.FileProvider"
      android:authorities="${applicationId}"
      android:grantUriPermissions="true">
      <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/file_paths"/>
    </provider>
  </application>
</manifest>

2. Check external path in your custom paths file. If it doesn't exist, create it in <projectDir>/android/app/src/main/res/xml/file_paths.xml:

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="external_files" path="."/>
</paths>
