Xamarin Forms move an apk file from a server to external storage

问题

  1. 如果您能提供帮助，请帮我将一个APK文件从服务器移动到外部存储。
  3. 我遇到了这个问题：Android.OS.FileUriExposedException: 'file:///storage/emulated/0/Download/MyAppApks/add.txt' 通过Intent.getData() 暴露在应用程序之外。
  5. var dir = Android.OS.Environment.GetExternalStoragePublicDirectory(Android.OS.Environment.DirectoryDownloads);
  6. var apkDirectory = new Java.IO.File(dir, "MyAppApks");
  7. apkDirectory.Mkdirs();
  9. var client = new HttpClient();
  10. var apkUrl = "http://**.**.**.**:2030/com.companyname.app1.apk";
  11. var response = await client.GetAsync(apkUrl);
  13. var apkFile = new Java.IO.File(apkDirectory, "com.companyname.app1.apk");
  14. using (var stream = new FileStream(apkFile.AbsolutePath, FileMode.Create, FileAccess.Write))
  15. {
  16.     await response.Content.CopyToAsync(stream);
  17. }
  19. var intent = new Intent(Intent.ActionView);
  20. intent.SetDataAndType(Android.Net.Uri.FromFile(apkFile), "application/vnd.android.package-archive");
  21. intent.SetFlags(ActivityFlags.NewTask);
  22. Android.App.Application.Context.StartActivity(intent);

使用以下代码：

  1. try this:
  3. using (var client = new WebClient())
  4. {
  5.     client.Headers.Add("user-agent", "other");
  6.     client.DownloadFile("http://**.**.**.**:2030/com.companyname.app1.apk", Android.OS.Environment.DirectoryDownloads + "/com.companyname.app1.apk");
  7. }
  9. string apkFile = Android.OS.Environment.DirectoryDownloads + "/com.companyname.app1.apk";
  11. var intent = new Intent(Intent.ActionView);
  12. intent.SetDataAndType(Android.Net.Uri.FromFile(apkFile), "application/vnd.android.package-archive");
  13. intent.SetFlags(ActivityFlags.NewTask);
  14. Android.App.Application.Context.StartActivity(intent);

注意：代码部分没有翻译。
