如何在单声道下载apk后开始安装
本文关键字：apk 下载 开始 安装 声道 单声道 | 更新日期: 2023-09-27 18:19:55
我一直在努力从我的私人服务器上更新我的应用程序。我无法让广播接收器工作，也无法使用简单的安装脚本。我快疯了。如有任何帮助，我们将不胜感激。
我的脚本
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)
{
}
如果我能在下载完后找到一种方法来启动应用程序的安装向导
我知道它必须请求权限

您需要使用Intent参数启动一个活动，如下所示：
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(apkUri, "application/vnd.android.package-archive");
apkUri是一个指向APK文件的URI。
好的，所以我找到了解决方案
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
新的工作代码
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);
新手问题，但它解决了
