Media.Plugin.CrossMedia TakePhotoAsync() in external class
Hello Guys and especially Hello @JamesMontemagno,
i have a question about the CrossMedia library to take photos in Xamarin.Forms.
To avoid duplicate code i wanted to outsource the code which takes the photo and return the taken photo as an MediaFile.
Heres what i tried to do:
ImageManager class:
public async Task TakePhoto()
{
// throw Alert if Camera isnt supported
if (!CrossMedia.Current.IsCameraAvailable || !CrossMedia.Current.IsTakePhotoSupported)
{
Acr.UserDialogs.UserDialogs.Instance.Alert("No Camera", "No Camera available.", "OK");
return null;
}
// take the photo asynchronous
MediaFile file = await CrossMedia.Current.TakePhotoAsync(
new StoreCameraMediaOptions
{
Directory = "asdf",
SaveToAlbum = true,
Name = "examplePhoto.jpg",
PhotoSize = PhotoSize.MaxWidthHeight,
MaxWidthHeight = 100,
});
return file;
}
and then call it from another class like this:
ImageManager imgManager = new ImageManager();
MediaFile file = imgManager.TakePhoto().Result;
What happens is that the camera app of the device opens and then rests in a blackscreen.
When i change the returntype of my TakePhoto()-Method to void, everything works fine.
Does somebody, or you James, know what to do?
Thank you very much, Gelatto

Can I publish to app store an app that contains a web view that points to a website ?
I have a web application that requires scanning capabilities.
My client uses Scandit for barcode scanning in other native apps. The web application will need to be able to use the scandit xamarin sdk in order to scan barcodes. I manged to call c# code from javascript and viceversa in order to be able to use the scandit xamarin sdk. My concern is if apple will aprove this type of app(website inside webview and using a third party library to scan and bring the result back to website).
I do not know if this makes sense. Please let me know if you need more information

Remoting to a Mac Mini / Best HDD for dev
Hi,
We're looking for options for multiple developers to work on XF/iOS apps. We also will be developing Android / UWP and are a company mostly focussed on .NET / Web services so MS-based development remains critical to us.
We're looking at Mac Minis as a way of multiple developers being able to work on Xamarin / iOS whilst retaining the ability for .NET/Web dev.
I've found using the simulator on Windows whilst connected remotely is always unreliable - although this was on a MacInCloud and also on a VM so may be down to resources but I'm yet to see it consistently work.
On that basis I want to use a Mac Mini which we'll remote to using VNC and develop directly in VS on Mac. Two questions:
1) Does this seem like a plausible option?
2) The Mac Minis on the Apple site have several HDD options; can anyone recommend which would be preferable over 256GB PCIe-based Flash Storage and a 1TB Fusion drive? I've heard build times can vary wildly depending on HDD type.
Thanks!

ZipFile.ExtractToDirectory issue
I've created a backup and restore procedure for my application. When the backup is run, it will create a .zip file of the SQLite database in the same directory as the database.
When restoring the database, it will rename the database, changing it from EPOSDatabase.db3 to tempEPOS.db3
Then, it takes the selected file and extracts it to the same location, under the name EPOSDatabase.db3, before deleting the renamed temporary database.
string dbPath = Environment.GetFolderPath(Environment.SpecialFolder.Personal);
if (File.Exists(dbPath + "/tempEPOS.db3"))
{
File.Delete(dbPath + "/tempEPOS.db3");
};
File.Move(dbPath + "/EPOSDatabase.db3", dbPath + "/tempEPOS.db3");
ZipFile.ExtractToDirectory(dbPath + "/" + fileToRestore, dbPath + "/EPOSDatabase.db3");
File.Delete(dbPath + "/tempEPOS.db3");
My issue is that when I then have code that opens the connection, for example when I open the system settings page after the restore has been carried out, I get an error: "Could not open database file: /data/user/0/com.companyname.ACPlus_MobileEPOS/files/EPOSDatabase.db3 (CannotOpen)"
As a further debug test, I added this code to the startup of the application:
string path = Environment.GetFolderPath(Environment.SpecialFolder.Personal);
foreach (var file in Directory.GetFiles(path))
{
string strFile = Convert.ToString(file);
}
public readonly string dbPath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Personal), "EPOSDatabase.db3");
var db = new SQLiteConnection(dbPath);
db.CreateTable<Category>();
db.CreateTable<SystemSettings>();
db.Close();
In the foreach loop, it only found the original .zip file that I was trying to restore from.
Then when it reaches the line
var db = new SQLiteConnection(dbPath);
it fails to create the database with the message ": Could not open database file: /data/user/0/com.companyname.ACPlus_MobileEPOS/files/EPOSDatabase.db3"
It seems like the file doesn't exist, so hasn't extracted properly, but if that was the case then why does it not just create a new database, rather than try to open it?

Hi, I'm a noob.
I'm trying get to work zxing barcode scanner.
I'm on Xamarin Forms and fire scanner via image tap gesture.
How can I be notified about scanned barcode in continuous mode?
I've got code like:
`public void ScanBarcode()
{
var scanner = new MobileBarcodeScanner();
scanner.UseCustomOverlay = false;
scanner.TopText = "Saome text";
scanner.BottomText = "Some text";
scanner.CancelButtonText = "Cancel";
var opt = new MobileBarcodeScanningOptions();
opt.DelayBetweenContinuousScans = 3000;
scanner.ScanContinuously(opt, HandleScanResult);
//scanner.Scan();
}
void HandleScanResult(ZXing.Result result)
{
string msg = "";
if (result != null && !string.IsNullOrEmpty(result.Text))
{
msg = "Scanned: " + result.Text;
DisplayAlert("Hi", msg, "OK");
}
else
{
msg = "Cancelled!";
DisplayAlert("Cancelled", msg, "OK");
}
}`
Doesn't get any notifications at all.
