At present i am using the below code for detecting mobiles, tablets. But i need to restrict this code to Mobile. Your suggestions can be appreciated if provided the solution.
DisplayModeProvider.Instance.Modes.Insert(0, new DefaultDisplayMode("Mobile")
{
ContextCondition = (context =>
{
var manager = (context.Cache[WurflManagerCacheKey] as IWURFLManager);
var cabablities = manager.GetDeviceForRequest(context.Request.UserAgent);
return cabablities.GetCapability("is_wireless_device") == "true";
//return cabablities.GetCapability("mobile_browser").Contains("Opera");
//return cabablities.UserAgent.Contains("Opera");
})
});
I would use the is_wireless_device and is_tablet capabilities to isolate only mobile phones:
if (is_tablet == false && is_wireless_device == true) {
//Must be a mobile phone
}

I'm building a voice call app for android using WebView. Everything works fine except in android 12, I can not use the earpiece (or even wired headphones in some phones) for audio out. The audio is always playing through loudspeaker. And some of the users reported that they can hear the internal ring(Which is a MediaPlayer object) in earpiece, but once the call answered it switches to loudspeaker. And the worst part is, I'm not able to reproduce this issue as this works perfectly on all my test phones (android 12).
My code,
private fun setAudioOutDevice(target: AudioDeviceInfo?) {
//need some delay for bluetooth sco
var audioChangeDelay: Long = 15
if (System.currentTimeMillis() - lastAudioChangeTime <= 300) audioChangeDelay = 300
Handler(Looper.getMainLooper()).postDelayed({
var targetDevice = target
//no device selected. scan all output devices and select one automatically
if (targetDevice == null) {
var wiredHeadsetDevice: AudioDeviceInfo? =
getAudioDevice(AudioDeviceInfo.TYPE_WIRED_HEADSET)
if (wiredHeadsetDevice == null) wiredHeadsetDevice =
getAudioDevice(AudioDeviceInfo.TYPE_WIRED_HEADPHONES)
val bluetoothDevice: AudioDeviceInfo? =
getAudioDevice(AudioDeviceInfo.TYPE_BLUETOOTH_SCO)
val speakerDevice: AudioDeviceInfo? =
getAudioDevice(AudioDeviceInfo.TYPE_BUILTIN_SPEAKER)
val earpieceDevice: AudioDeviceInfo? =
getAudioDevice(AudioDeviceInfo.TYPE_BUILTIN_EARPIECE)
//update global variables
isBluetoothAvailable = bluetoothDevice != null
//disable BT if wired headset connected
if (wiredHeadsetDevice != null) isBluetoothAvailable = false
//choose an output device
targetDevice =
if (callType == videoCall && bluetoothDevice == null && wiredHeadsetDevice == null) speakerDevice
else if (callType == videoCall && wiredHeadsetDevice == null && !isBluetoothAudioEnabled) speakerDevice
else wiredHeadsetDevice
?: if (isBluetoothAvailable && isBluetoothAudioEnabled && bluetoothDevice != null) bluetoothDevice
else earpieceDevice ?: speakerDevice
//no earpiece
if (earpieceDevice == null) {
setBigStatus("Unable to access Earpiece", 0)
}
}
//set output device
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
var success = false
try {
// am.clearCommunicationDevice()
if (targetDevice != null) success = am.setCommunicationDevice(targetDevice)
} catch (e: Exception) {
debugMsg(e.message.toString())
}
if (!success) setBigStatus(getString(R.string.unable_to_set_audio), 0)
}
//older devices, android 11 or lower
else {
am.mode = AudioManager.MODE_IN_COMMUNICATION
if (targetDevice?.type == AudioDeviceInfo.TYPE_BUILTIN_SPEAKER) {
changeSco(false)
am.isSpeakerphoneOn = true
} else {
if (targetDevice?.type == AudioDeviceInfo.TYPE_BLUETOOTH_SCO) changeSco(true)
else changeSco(false)
am.isSpeakerphoneOn = false
}
}
}, audioChangeDelay)
}
private fun changeSco(enable: Boolean) {
if (enable) {
am.startBluetoothSco()
am.isBluetoothScoOn = true
} else {
am.stopBluetoothSco()
am.isBluetoothScoOn = false
}
}
private fun getAudioDevice(type: Int): AudioDeviceInfo? {
val audioDevices = am.getDevices(AudioManager.GET_DEVICES_OUTPUTS)
for (deviceInfo in audioDevices) {
if (type == deviceInfo.type) return deviceInfo
}
return null
}
The above code is working fine on android 11 and lower and even on some android 12 phones. How can I make this work on all devices?
There is an issue tracker here. But it seems that nobody is working on it.
UPDATE Today I tried it on a pixel 3a and it gives mixed behaviors. Sometimes it plays on the earpiece or wired headset but for most of the calls, it plays on the loudspeaker only. And even if I don't set any mode, it automatically switches to MODE_IN_COMMUNICATION right after the stream starts. I think, android is trying to figure out the proper mode by itself and that messing with my app logic.
I am working with a shopping cart application. I have developed an application that maintains user shopping carts using cookies. It was working perfectly until I have made some UI changes and now it is not working now I have no clue what I have done wrong because I am maintaining the cookies through c# backend code no interruption with the front end only reading these cookies and passing them into view model to show on cart panel. Here is my code
Startup.cs
app.UseRouting();
app.UseCookiePolicy();
app.UseAuthentication();
Adding Items to Cart
public JsonResult AddToShoppingCart(UserProductVM model)
{
try
{
if (string.IsNullOrEmpty(model.SelectedSize))
return Json(new { status = false, msg = "Please select size to proceed." });
var result = ShoppingCartHelper.GetShoppingCartList(model, _httpContextAccessor);
if (result.Status <= 0)
return Json(new { status = false, msg = result.Message });
Response.Cookies.Delete("ShoppingCart");
Response.Cookies.Append("ShoppingCart", JsonConvert.SerializeObject(result.Data));
return Json(new { status = true, msg = "Success! added to shopping cart." });
}
catch (Exception ex)
{
return Json(new { status = false, msg = ex.Message.ToString() });
}
}
Reading From Cart
public static string GetShoppingCartFromCookies(IHttpContextAccessor _httpContextAccessor)
{
return _httpContextAccessor.HttpContext?.Request?.Cookies["ShoppingCart"]?.ToString();
}
Every Thing was working fine and now nothing works no cookies are added to the cookies list. This is the same code I have also the backup my application and when I run that application cookies are working perfectly but the problem is that it is with the old design I am not using that UI design anymore. This is the same code working in one application but not working with another application with a different UI.
Have you added the IHttpContextAccessor to dependency container ?
services.TryAddSingleton<IHttpContextAccessor, HttpContextAccessor>();
I have resolved my issue. The problem was basically I was adding base64 image string which was not working. When I comment on this line it worked perfectly no need to change any code.
public static GenericResponseDTO<List<ShoppingCartViewModel>> GetShoppingCartList(UserProductVM model, IHttpContextAccessor _httpContextAccessor)
{
var shoppingcartmodel = new List<ShoppingCartViewModel>();
var cartmodel = new ShoppingCartViewModel
{
RestaurantId = model.RestaurantId,
SubCategoryId = model.SubCategoryId,
RestaurantSubCategoryId = model.RestaurantSubCategoryId,
OrderGuid = Guid.NewGuid(),
Quantity = model.Quantity,
//ItemImage = model.ItemImage,
SelectedSize = model.SelectedSize.Split('-')[0],
SingleItemPrice = Convert.ToDecimal(model.SelectedSize.Split('-')[1]),
SubCategoryName = model.SubCategoryName,
TotalItemPrice = (model.Quantity * Convert.ToDecimal(model.SelectedSize.Split('-')[1]))
};
if (string.IsNullOrEmpty(GetShoppingCartFromCookies(_httpContextAccessor)))
shoppingcartmodel.Add(cartmodel);
else
{
shoppingcartmodel = JsonConvert.DeserializeObject<List<ShoppingCartViewModel>>(GetShoppingCartFromCookies(_httpContextAccessor));
if (shoppingcartmodel.Any(x => x.RestaurantSubCategoryId == model.RestaurantSubCategoryId))
return new GenericResponseDTO<List<ShoppingCartViewModel>> { Data = new List<ShoppingCartViewModel>(), Status = -1, Message = "Item is alreay exists in your cart please remove and add another." };
shoppingcartmodel.Add(cartmodel);
}
return new GenericResponseDTO<List<ShoppingCartViewModel>> { Data = shoppingcartmodel, Status = 1 };
}
I have commented on the ItemImage line and it works like a charm. Maybe it helps someone else problem.
I'm trying to add barcode scanner feature to my xamarin.ios app. I'm developing from visual studio and I've added the Zxing.Net.Mobile component from xamarin components store.
I've implemented it as shown in the samples:
ScanButton.TouchUpInside += async (sender, e) => {
//var options = new ZXing.Mobile.MobileBarcodeScanningOptions();
//options.AutoRotate = false;
//options.PossibleFormats = new List<ZXing.BarcodeFormat>() {
// ZXing.BarcodeFormat.EAN_8, ZXing.BarcodeFormat.EAN_13
//};
var scanner = new ZXing.Mobile.MobileBarcodeScanner(this);
//scanner.TopText = "Hold camera up to barcode to scan";
//scanner.BottomText = "Barcode will automatically scan";
//scanner.UseCustomOverlay = false;
scanner.FlashButtonText = "Flash";
scanner.CancelButtonText = "Cancel";
scanner.Torch(true);
scanner.AutoFocus();
var result = await scanner.Scan(true);
HandleScanResult(result);
};
void HandleScanResult(ZXing.Result result)
{
if (result != null && !string.IsNullOrEmpty(result.Text))
TextField.Text = result.Text;
}
The problem is that when I tap the scan button, the capture view is shown correctly but if I try to capture a barcode nothing happens and it seems the scanner doesn't recognize any barcode.
Someone has experienced this issue? How can I made it work?
Thanks in advance for your help!
I answered a similar question here. I couldn't get barcodes to scan because the default camera resolution was set too low. The specific implementation for this case would be:
ScanButton.TouchUpInside += async (sender, e) => {
var options = new ZXing.Mobile.MobileBarcodeScanningOptions {
CameraResolutionSelector = HandleCameraResolutionSelectorDelegate
};
var scanner = new ZXing.Mobile.MobileBarcodeScanner(this);
.
.
.
scanner.AutoFocus();
//call scan with options created above
var result = await scanner.Scan(options, true);
HandleScanResult(result);
};
And then the definition for HandleCameraResolutionSelectorDelegate:
CameraResolution HandleCameraResolutionSelectorDelegate(List<CameraResolution> availableResolutions)
{
//Don't know if this will ever be null or empty
if (availableResolutions == null || availableResolutions.Count < 1)
return new CameraResolution () { Width = 800, Height = 600 };
//Debugging revealed that the last element in the list
//expresses the highest resolution. This could probably be more thorough.
return availableResolutions [availableResolutions.Count - 1];
}
I'm working on a mobile app using jQuery Mobile and I would like to check if I'm on iOS5, cause it has some great features, like true fixed toolbars, etc. I'm looking for a javascript solution.
This works for me with a bit of string manipulation of the user-agent.
var ua = navigator.userAgent;
var detail = ua.split('(')[1];
var device = detail.split(';')[0];
if (device == 'iPhone' || device == 'iPod' || device == 'iPad') {
var ios = detail.split(' ')[5].split('_')[0];
if (ios == '5') {
alert('ios 5');
}
}

0) What kind of extension is this? I assume it's a regular extension requiring restart; bootstrapped (restartless) extensions have their own uninstall notification.
1) Per the MDC docs, the em-action-requested notification was replaced with a different notification in Firefox 4+, are you testing with Firefox 4 or 3.6?
2) How exactly is gBrowser.addTab "not working over here"? Does the code get to that point? Do you get any messages in the Error Console (see that page for set up tips)? If you put your code in an XPCOM component (which is correct), you'll first have to get a reference to a browser window. See Working with windows in chrome code.
I don't think that the em-action-requested topic is posted to observers until the extension is actually uninstalled, which happens on restart (assuming it is not a restartless extension). When are you expecting the new tab to appear? I would try setting a pref when the uninstall topic is triggered and checking for that pref on startup. If it is there, you can display your tab and remove the pref.
