android 软件更新 app安装 更新

app更新有以下几点需要注意

1. 安卓7.0以上需要动态申请文件读写权限

2.安卓8.0以上安装第三方应用需要手动打开设置给予权限。

3.manifest需要注册下载服务service

4.manifest需要配置provider，否则文件读取失败

--------------------------------------------------------------------------以下是代码

1.res下新建文件夹xml,在xml文件夹下新建文件file_paths.xml

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <root-path
        name="root_path"
        path="." />
</paths>

2.AndroidManifest文件的配置

 <!--   Manifest中也要声明安装permission  -->

    <uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />

  <!--   需要注册服务 DownloadService文件是新建的下载管理  -->
        <service android:name=".DownloadService" />
        <!--  authorities 值需要和DownloadService里面一个参数对应。 更新：已经被放到activity里面了   -->
        <!--  resource 是res文件夹下xml文件夹下的一个资源文件,名字要对应   -->
        <provider
            android:name="android.support.v4.content.FileProvider"
            android:authorities="com.example.fgh.google.fileprovider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/file_paths" />
        </provider>

3.新建文件DownloadService.java

package com.openfood.rider.utils;


import android.app.DownloadManager;
import android.app.Service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.database.Cursor;
import android.net.Uri;
import android.os.Binder;
import android.os.Environment;
import android.os.IBinder;

import com.openfood.rider.DeliveryApplication;
import com.openfood.rider.R;
import com.openfood.rider.view.ToastCustom;

import java.io.File;
