服务端提供版本信息和apk下载地址客户端通过对比版本进行文件下载安装升级

在application节点中加入下面代码
provider android:nameandroidx.core.content.FileProvider android:authoritiescom.companyname.boshiac.forklift.app.fileprovider android:exportedfalse android:grantUriPermissionstruemeta-data android:nameandroid.support.FILE_PROVIDER_PATHS android:resourcexml/provider_paths //provider添加文件如下图 provider_paths.xml内容
根据自己的权限需要开放对应的目录权限就可以了
?xml version1.0 encodingutf-8?

注意事项在iis中或者.netcore中下载apk配置方式不一样
在iis中配置网络上有很多文章都是配置mime”application/vnd.android.package-archive“ 这个是没有问题的如下配置
在.netcore中需要做如下配置 program.cs 或者startup文件中增加如下代码 app.UseStaticFiles(new StaticFileOptions{//FileProvider new PhysicalFileProvider(Directory.GetCurrentDirectory()),//设置不限制content-type 该设置可以下载所有类型的文件但是不建议这么设置因为不安全//下面设置可以下载apk和nupkg类型的文件ContentTypeProvider new FileExtensionContentTypeProvider(new Dictionarystring, string{{ .apk, application/vnd.android.package-archive }})}).UseStaticFiles();完整代码
