Unable to connect to firebaseio.com - android

OK, this may not be the right place to post this, but I am exhausted on ideas.
I have an Ionic2 app with AngularFire2. I can not connect to firebaseio.com from the mobile device.
It is likely a whitelist issue, but damned if I can find it. I have
<allow-intent href="https://*.firebaseio.com/*" />
everything woks fine in an emulator, localhost, just not on the physical device. I connected to the app running remote device with chrome-tools and did see that I am not connecting to the firebaseio.com server. I see
Failed to load resource appname.firebaseio.com/.lp?start=t&ser=94215074&cb=12&v=5
Failed to load resource appname.firebaseio.com/.lp?start=t&ser=94215074&cb=12&v=5
The status is (failed), not 404, not 500, just (failed).
I have updated everything. Firebase 2.7.8, Ionic-cli 2.2.3, angular 4.0.0, angularfire2 4.0.0-rc0 still same errors.
I have added the following the following cordova plugins, but nothing seems to help.
cordova-plugin-buildinfo
cordova-universal-links-plugin
cordova-plugin-browsertab
cordova-plugin-inappbrowser
Any insight would be greatly appreciated.

Do you need to change https://.firebaseio.com/ to https://*.firebaseio.com/* ? (missing *s)
Per the cordova docs:
Wildcards are allowed for the protocol, as a prefix
to the host, or as a suffix to the path
Example:
<allow-intent href="*://*.example.com/*" />

You currently have .firebaseio.com (emphasis on the . before firebaseio). Usually you'll need to do something like https://*.firebaseio.com

The platforms were corrupt. I removed and added the android platform and that resolved the issue.

Xamarin Android error on DeviceInfo.Model

I have a Xamarin for Android app that has been working until today. I needed to make a change but before I did, I ran a test to ensure no VS or Nuget package updates caused an issue. I have Xamarin.Essentials in my app and this line worked before, not sure what is happening now.
if(DeviceInfo.Model == "TC72"){scannerIndex = 1;}
Exception Unhandled:
Xamarin.Essentials.NotImplementedInReferenceAssemblyException: 'This
functionality is not implemented in the portable version of this
assembly. You should reference the NuGet package from your main
application project in order to reference the platform-specific
implementation.'
Any insight would be helpful. TIA
I changed the DeviceInfo.Model to Build.Model and get the same info I was expecting. That fixed my issue. If anyone has a different suggestion, happy to entertain them.
Added 8/11/21 3:25pm CT
I also found that changing my Compile Target to 10.0 fixed the Xamarin.Essentials issues. So far the application is working on 8.1 on the device (Zebra MC3300).

java.lang.IllegalStateException: Couldn't find implementation for Permissions interface

My expo react-native application is working perfectly fine locally, in dev mode (Expo Go). But it crashes mercilessly in production when downloaded from Google Play Store and upon installation. Using logcat, the error message is:
java.lang.IllegalStateException: Couldn't find implementation for Permissions interface.
The only permission related code is a notifications permission request with expo-notifications.
import * as Notifications from 'expo-notifications';
...
await ExpoNotifications.getPermissionsAsync();
...
await ExpoNotifications.requestPermissionsAsync();
Any help would be greatly appreciated
Thank you for helping solve this issue.
Encountered a similar issue.
Seems that expo-permissions is deprecated. Reference here.
What solved my issue was to remove expo-permission package from the project.
cd ProjectName
expo uninstall expo-permissions
OR
npm uninstall expo-permissions
I had the same issue and managed to get it work after updating expo-notifications:
npm install expo-notifications#0.12.2
Other people mentioned that they had to update other expo related packages because expo-permissions is deprecated, just like #sanjeev mentioned above.

Cordova - Emulate [platform] builds fine, but fails within the app

I've converted an Angular 5 project into Cordova project.
When I run cordova emulate browser, my application works great.
How ever, when I try to emulate it on Android or iOS it builds fine, but it fails within the application.
Android Error:
D/SystemWebChromeClient: file:///android_asset/www/vendor.2f2a0573c67e0d8a78d3.bundle.js: Line 1 : ERROR
I/chromium: [INFO:CONSOLE(1)] "ERROR", source: file:///android_asset/www/vendor.2f2a0573c67e0d8a78d3.bundle.js (1)
iOS Error:
NSURLConnection finished with error - code -1100
I noticed that if I remove
<script type="text/javascript" src="main.5bc80649598bbc3df9fa.bundle.js"></script>
There won't be any error, but my app obviously won't load since it's compiled JS is in that file.
What could be causing this problem? I'm sure that it's an issue in configuration or permissions, as the app works fine in browser.
On Android I tried adding
<preference name="loadUrlTimeoutValue" value="120000" />
to config.xml but it didn't give any improvement.
Your error (-1100) mean: NSURLErrorFileDoesNotExist
I think you try to get that file from wrong location.
Try to check path structure in generated filesystem assets or with web inspector and check if file is there:
file:///android_asset/www/vendor.2f2a0573c67e0d8a78d3.bundle.js

Camera Plugin Issue on Phonegap 3.3

I'm trying to use the Full Example given in:
http://docs.phonegap.com/en/3.3.0/cordova_camera_camera.md.html#camera.getPicture
I've created a project, added platform Android, added the Camera Plugin,
Then I've copied the example as is into index.html .
Ran it on an Android 4.3 device, I see an error in the Eclipse's console:
01-22 19:48:26.661: E/Web Console(22707): Uncaught TypeError: Cannot read property 'PictureSourceType' of undefined:19
(Yes onDeviceReady() is fired like it should)
What am I doing wrong ?
Thanks.
Try changing:
pictureSource=navigator.camera.PictureSourceType;
to:
pictureSource=navigator.camera.PictureSourceType.CAMERA;
If you use phongap build you have to add:
<gap:plugin name="org.apache.cordova.core.camera" />
to your config.xml no need cordova add plugin etc..
From what I've experienced with this camera plugin, sometimes the plugin won't expose the window.camera as is. Instead, try to access it through window.plugins, and if that doesn't work either, try using ngCordova with which you will be able to get it working faster.
You should also know that there are some bugs in Android which may crash the Android app.

Phonegap device is undefined on both android and iOS

While using the Phonegap platform I've ran in to a problem. When trying to access any of the device strings, e.g. device.name or device.platform, I get as value undefined. This occurs on both iOS and Android. I've set the permissions for Android in both the ApplicationManifest and the config.
While doing research into the problem i found that the problem could be the the device functionality will only be available after about 1 to 3 seconds. I've ran some test, set a timeout at 10 seconds or even perform the action manually via onClick at different times (up to several minutes), but i keep getting the undefined value.
I've tried window.device.name instead of device.name, same result.
Does anyone have a clue why this is happening?
Running Phonegap 2.3.0 on iOS 6.0.2 and Android 4.1.2
Code:
$('#deviceName').html('Name: ' + device.name);
$('#devicePlatform').html('Platform: ' + device.platform);
$('#devicePlatformVersion').html('Version: ' + device.version);
Full Code here
Your help is mush appreciated!
"WARNING: device.name is deprecated as of version 2.3.0. Use device.model instead."
Refer to the following: http://docs.phonegap.com/en/edge/cordova_device_device.md.html#device.name
Accessing the Feature
As of version 3.0, Cordova implements device-level APIs as plugins. Use the CLI's plugin command, described in The Command-Line Interface, to add or remove this feature for a project:
cordova plugin add org.apache.cordova.device
As found in the documentations here:
http://docs.phonegap.com/en/edge/cordova_device_device.md.html
or
https://github.com/apache/cordova-plugin-device/blob/master/doc/index.md
device.model might be what you want.
