我一直在努力让我的应用程序从我的私人服务器更新我无法让广播接收器工作，也不是简单的安装脚本请我疯了任何帮助都会深深感激。

我的剧本

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.Site.cc/Folder/app.apk");

            // If required by the server, set the credentials.
            //request.Credentials = CredentialCache.DefaultCredentials;
            //request.IfModifiedSince = DateTime.Parse("01-01-1990");
            try
            {
                using (WebResponse response = request.GetResponse())
                {

                    //DateTime dt = System.IO.File.GetCreationTime(FilePath);        //.GetLastWriteTime(FilePath);
                   // DateTime appDate = DateTime.Parse(response.Headers["Last-Modified"].ToString());

                    try
                    {
                        ad = new AlertDialog.Builder(this).Create();
                        ad.SetTitle("INFO");

                        ad.SetMessage("Get New version");
                        ad.SetButton("NOW", delegate
                        {


                            System.IO.File.Delete("/filepath/app.apk");
                            string url = "http://www.Site.cc/Folder/App.apk";
                            DownloadManager.Request Request = new DownloadManager.Request(Android.Net.Uri.Parse(url));
                            Request.SetDescription("Inspections Application");
                            Request.SetTitle("Download Inspections");
                            // in order for this if to run, you must use the android 3.2 to compile your app
                            if (Build.VERSION.SdkInt >= BuildVersionCodes.HoneycombMr1)
                            {
                                Request.AllowScanningByMediaScanner();
                                Request.SetNotificationVisibility(DownloadVisibility.VisibleNotifyCompleted);
                                Request.SetMimeType("application/vnd.android.package-archive");
                                Request.SetVisibleInDownloadsUi(true);

                            }
                            Request.SetDestinationInExternalPublicDir(Android.OS.Environment.DirectoryDownloads, "Inspections.Inspections-Signed.apk");

                            // get download service and enqueue file
                            DownloadManager manager = (DownloadManager)GetSystemService(Context.DownloadService);
                            manager.Enqueue(Request);


                        });
                        ad.SetButton2("LATER", delegate
                        {
                            return;
                        });
                        //ad.SetButton("Continue",new IDialogInterfaceOnClickListener listner);
                        ad.SetCanceledOnTouchOutside(true);
                        ad.Show();


                    }
                    catch (System.Exception ex)
                    {
                        ad = new AlertDialog.Builder(this).Create();
                        ad.SetTitle("INFO");
                        ad.SetMessage(ex.Message);
                        ad.SetCanceledOnTouchOutside(true);
                        ad.Show();
                    }
                   /* 
                        cL.DownloadFile("http://www.site.cc/folder/app.apk", Path);
                        Intent promptInstall = new Intent(Intent.ActionView).SetData(Android.Net.Uri.Parse("/sdcard/Download/Inspections.Inspections-Signed.apk")).SetType("application/vnd.android.package-archive");
                        StartActivity(promptInstall); 
                    */
                    //string lastModified = DateTime.Parse(response.Headers["Last-Modified"].ToString()).ToString();
                }
            }
            catch (WebException wex)
            {

            }

如果我可以找到一种方法来启动应用程序完成下载后的安装工具

我知道它必须要求权限

2 个答案:

答案 0 :(得分：0)

您需要使用如下的Intent参数启动活动：

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(apkUri, "application/vnd.android.package-archive");

apkUri是指向您的APK文件的URI。

答案 1 :(得分：0)

好的，我找到了解决方案

System.IO.File.Delete("/sdcard/download/App_Name.apk"); //Delete previous version


cL.DownloadFile("http://www.Site.cc/Folder/App_Name.apk", "/sdcard/download/App_Name.apk");// Download new app via HttpWebRequest

新工作代码

Intent promptInstall = new Intent(Intent.ActionView).SetDataAndType(Android.Net.Uri.FromFile(new Java.IO.File(Android.OS.Environment.ExternalStorageDirectory + "/download/" + "App_Name.apk")), "application/vnd.android.package-archive");
promptInstall.AddFlags(ActivityFlags.NewTask);
StartActivity(promptInstall);

旧的不工作代码

Intent promptInstall = new Intent(Intent.ActionView).SetData(Android.Net.Uri.Parse("/sdcard/Download/App_Name.apk")).SetType("application/vnd.android.package-archive");
promptInstall.AddFlags(ActivityFlags.NewTask);
StartActivity(promptInstall);
