RefreshView when target paltform is UWP it is not working i.e I'am unable to apply pull to refresh, but on iOS and Android it is Working fine.
RefreshView when target paltform is UWP it is not working
I have to say the RefreshView only avaiable for touch screen, if you use mouse mode, it will not response your drag gestue. please run your app with simulator or touch device.
For more detail please refer to Run UWP apps in the simulator document

I have a brand new Samsung A10 with Pie on it.
I'm attempting to run the Sample Application provided in MediaPlugin:
https://github.com/jamesmontemagno/MediaPlugin
At first I was getting this error when I tried to build:
Invalid value 'armeabi' in $(AndroidSupportedAbis). This ABI is no
longer supported. Please update your project properties to remove the
old value. If the properties page does not show an 'armeabi' checkbox,
un-check and re-check one of the other ABIs and save the changes.
Then I did some reasearch and went to Android Properties / Android Options / Advanced and unselected armeabo-v7a.
As I understand it this will remove 32 but support, which I'm fine with.
Now I get this error:
ADB0020: Android ABI mismatch. You are deploying an app supporting
'x86;x86_64;arm64-v8a' ABIs to an incompatible device of ABI
'armeabi-v7a;armeabi'. You should either create an emulator matching
one of your app's ABIs or add 'armeabi-v7a' to the list of ABIs your
app builds for.
I'm targeting a new A10 Samsung phone with Android Pie on it. I can't see where to set the 'device ABI', though why would a new Pie phone be interseted in armeabi-v7a anyway?
Where can I set the 'device ABI' or otherwise fix this?
I can't find anything on Google. Thanks.
UPDATE
I've found this work around which is as worrying as it is bizarre:
Untick the armeabi-v7a option
Build
Re-tick the option
Build
Deploy

I'd like to understand what's going on here rather than just work around it.
This is only an issue with my A10 physical Samsung phone, in emulators it seems to work fine.
I got this error before. You could untick all the supported architectures to tick all of them like below. Delete the obj and bin folder of project to clean and rebuild. Most of times, it works.
Different Android devices use different CPUs, which in turn support different instruction sets. Each combination of CPU and instruction set has its own Application Binary Interface (ABI).
For more support of Android ABIs, you could refer to the Android ABIs guides.
https://developer.android.com/ndk/guides/abis
To fix this issue on a Xamarin.Forms Android application, Right click on your android project and then select Properties > Android Options > Advanced.
You will see a dropdown for supported architectures. Select x84 & x86_64.
The app should now build and run on the emulator.
go to your project folder and edit yourproject.csproj
and remove starting <AndroidSupportedAbis> line completely.
add:
<AndroidSupportedAbis>armeabi-v7a;x86_64;arm64-v8a;x86</AndroidSupportedAbis>
save and debug. (changes accept on visual studio)
Enjoy.
Do not setup retry abis on xamarin.
I changed to Debug mode from Release mode after signing a release.
For Mac:
Android Project -> Option -> Android Build -> Advanced. Then tick all.
Click Option from Solution Explorer for Android:
Click Android Build then Advanced:
I am trying to create a watchOS app in an existing Xamarin Forms application in Visual Studio 2017 on Windows. I have followed all the steps listed here. I have also added watchOS app project reference to the main iOS app by selecting add reference option of the references node of the main iOS app. Solution also builds successfully but when I try to launch watchOS app in watch simulator, it instantly throws the below error without even launching the simulator.
Error:
Main iOS app couldn't be found, please make sure you've created an iOS app and it is referencing
Please suggest what I am doing wrong.
I think you have add the watchOS app reference in a wrong place.
You should add the reference in xxx.iOS projecct instead of xxx(xamarin.forms project).
Let me show a screenshot for you:
Update:
Steps:
I create a new MobileApp(Xamarin.forms) project(platform iOS).
Right click on the solution -->add --> new project -->Apple Watch -->watchOS app-->ok.
Right click on the xxx.iOS project --> add---> reference --> check XXX.watchOSApp
Right click on the xxx.WatchOSApp --> Set as Setup Project.
(Clean and rebuild) Run on the appleWatch simulator.
When developing a web app using ionic, it is very useful to run up the program in iOS simulator with the command line
ionic run ios -l -c -s --target="iPhone-5s"
Then by selecting desktop Safari and Develop -> iOS Simulator you can bring up the Web Inspector for the app on the simulator.
All well and good.
On desktop Safari, it is very useful to right-click on an element to find it in the Web Inspector. Is there a way to do this in iOS Simulator Safari ?
I end up putting a searchable string into the HTML and Ctrl-F to find it which is more cumbersome.
There is a target button in the web inspector window that can select an element inside the iOS Simulator. Here's a screenshot:
"Select Element" button in Web Inspector

Most of ionic android developers face this issue because of different verions of web-views environment on different devices. Solution of this is to add crosswalk plugin to your project.This makes your Cordova / Ionic application use the Crosswalk WebView instead of the System WebView. It patches own browser with application so it runs in that having same specific environment on each device. So application behavior will be same on each device.
add this plugin using following command:
ionic plugin add cordova-plugin-crosswalk-webview
More about Crosswalk, see link : https://crosswalk-project.org
Read this blog post by ionic to understand how it helps you stablize and improve behavior of hybrid applications across all versions of android.
I have a phongap app with a sqlite plugin that runs in both android and iphone. When I try to run it in Ripple i get several errors depending on the inclusion of the cordova version and device I use. Non of them are working at all. In some comments in stackoverflow i've seen people running sqlite in phonegap under ripple.
I'm using the PG-SQLitePlugin-Android plugin in my project, which it acually only supports Phonegap 2.7.0+.
I've found that i can force Ripple to use 2.7.0 by calling it :
file://localhost/Users/----/----/----/www/index.html?enableripple=cordova-2.7.0
Ripple actually loads great after enabling access to file system through chrome.
When i include cordova-2.7.0.js in my script
The index.html pops me a pop up with the following text :
gap:["Device","getDeviceInfo","Device119187522"]
that i can accept or cancel, then 2 more dialogs appeare, if I accept it gets hanged.
the js console shows that cordova 2.7.0 is really running :
Falling back on PROMPT mode since _cordovaNative is missing. Expected for Android 3.2 and lower only. cordova-2.7.0.js:906
deviceready is not fired
When i include cordova-2.9.0.js in my script
It happens the same as 2.7
Falling back on PROMPT mode since _cordovaNative is missing. Expected for Android 3.2 and lower only. cordova-2.7.0.js:906
but this time I get this other errors
Failed to load resource file://localhost/Users/laullobetpayas/-------/---/------/www/cordova/cordova_plugins.json
Failed to load resource file://localhost/Users/-------/---/------/www/cordova/cordova_plugins.js
deviceready is not fired
When I don't include any cordova.js in my script
SQLitePlugin.js:31
Uncaught ReferenceError: cordova is not defined SQLitePlugin.js:34
Am I using the proper plugin ?
which is the propper version of cordova / device tu run with the plugin and ripple ?
Do i have to include the cordova.js in my project
Hel will be very apreciated, it's for a long time that I'm trying to solve this.
Thank you in advanced.
Phonegap plugins won't work with Ripple because the idea of a Phonegap plugin is that it provides a Javascript interface in order to execute native code. That means, in the case of Android, the Javascript will invoke native Java code and in the case of iOS, the Javascript will invoke native Objective-C.
Ripple is purely Javascript-based, so the Javascript part of the plugin has nothing to interface with.
In the case of the SQLitePlugin, for example, calling SQLitePlugin.close() results in the call:
cordova.exec(null, null, "SQLitePlugin", "close", [this.dbname]);
where SQLitePlugin is the native class name and close is the native function name.
If you want to use the same storage API across Android, iOS and Ripple, maybe consider using lawnchair with appropriate adapters.
As for the issues with Ripple and Phonegap 2.7.0/2.9.0, Ripple has not quite caught up with Phonegap, so you will get these popups and error messages in the console, but that will not stop your Phonegap app (without native plugins) running in Ripple. You can convince yourself of this with a simple test case like:
document.addEventListener("deviceready", function(){
alert("I'm alive");
});
But the answer is, yes, you do need to include cordova.js in order for it to work at all in Ripple.
The Cordova-SQLitePlugin is a drop-in replacement for the HTML5 SQL API, so when running inside Ripple you don't need to call the Cordova layer you can just replace calls to sqlitePlugin.openDatabase() with window.openDatabase(). I've not yet tested this with Ripple but it should work. There are some database size limitations but this is probably all you need for testing.
There several ways to test if your inside Cordova. You could create a shim for the openDatabase() method based on testing for Cordova on app startup.
Since your primary goal is really to do rapid testing of SQLite with Cordova (rather than specifically to use Ripple) I'd like to suggest another new alternative to using Ripple.
I wrote an app call Sencha Touch Live that can be used for rapid development of Cordova / HTML5 apps by allowing you to Live Edit and Debug the HTML/JS/CSS code on your mobile device simply by updating files on your development computer - so you can skip most recompile/redeploy/restart debugger time costs. It has tons of other cool features. I'm using it myself for SQLite app testing instead of Ripple or Weinre
Detailed overview and Step by Step Guides
Installation Guide
It's based on the code from Adobe's PhoneGap Developer App so core code is well tested. It's been extensively adapted and tuned for Sench Touch framework though it should also work for jQuery Mobile or any framework that places HTML5 code under the phonegap/www or cordova/www folder. Just start up the server in you PhoneGap or Cordova project folder.
For testing your SQL and controller logic, I recommend using Geny Motion emulator with a version of Android 4.4.x KitKat. Start up an recent version of Chrome on your desktop and once you get your app working on the emulator or real device open chrome://inspect and now you can use the full Chrome debugger on your remote device app. You can also use a recent version of Safari for OSX/iPhone Simulator testing.
You can watch a demo here (starts at the 5 min. mark). Yes! It needs a more polished video with less echoes but you'll get the idea:
