Readme after installation of Microsoft.UI.Xaml NuGet tells to put <XamlControlsResources xmlns="using:Microsoft.UI.Xaml.Controls" /> into app resources.
But looks like this class does not exist in Uno.
Here I see that it is added in code and with conditional compilation.
This class is not yet supported in Uno at this point. To add support for it on Windows only, you can add the following in your App.xaml.cs:
#if NETFX_CORE
Resources.MergedDictionaries.Add(new Microsoft.UI.Xaml.Controls.XamlControlsResources());
#endif

I have a framework binary built with Swift that I'm trying to incorporate into an Objective-C project. However the class in the framework isn't available.
In the swift framework, the class is defined like this:
#objcMembers
#objc public final class Messaging: NSObject, UINavigationControllerDelegate, LogsManagerDelegate {
...
}
I drag the archived and exported framework directly into the project to use and make sure the Defines Module is set to Yes in the Build Settings.
In the Objective-C I try to use the framework:
#import ContactAtOnceMessaging;
#implementation MessagingExperience
Messaging *messaging; // Unknown type name 'Messaging'
...
#end
If I drag the code for the framework directly into the project, Messaging is a known class so I know the Swift is okay.
I also tried changing the import to the following, but that didn't work.
#import "ContactAtOnceMessaging/ContactAtOnceMessaging-Swift.h"
I also tried using CocoaPods to import the framework and that hasn't helped.
What am I doing wrong?
I can confirm that I experienced the same problem as you. I was also able to resolve it. I'm not sure if the original problem was caused by an anomaly somewhere in my configuration. I did, however, test the following procedure and found it to work reliably with Xcode 9.3.
I first made a test Swift framework named Dynamic-Framework-Tester, in an Xcode project, and set it to be copied to an absolute path on every build.
I then performed the following steps to setup my Objective-C project:
Made a new project with Objective-C as the language.
Dragged the framework from its absolute path into the project without choosing "Copy items if needed".
Deleted the framework from Linked Frameworks and Libraries because it will get added automatically in step (4).
Added the framework to Embedded Binaries.
In build settings, set Always Embed Swift Standard Libraries to Yes.
Added my custom framework path to the Framework Search Paths setting in the build settings.
In the Objective-C project, I imported the framework using
#import Dynamic_Framework_Tester;
and called a method exposed in the framework from Objective-C.
Using a simulator, I was able to update the framework and have the changes applied on subsequent runs of the app.
Having proguard issues since last update. (project and sdk, API 19)
First, com.android.dex.DexException: Multiple dex files define Lcom/google/gson/JsonSerializer;
OK, visiting bin/proguard and unjarring obfuscated.jar I do see com/google/gson/JsonSerializer declared there. Why? It should be in the lib only.
That is the crux of the question, why is Proguard copying in classes from the libs jars into ""?
And what is "" anyways? Progaurd fails saying the class is defined in gcm and "". What is ""? The class in only defined in libs/gcm.jar and nowhere else before I run the build.
Longer version, I add this to my proguard config:
-libraryjars libs(!gson-2.1.jar,!RSAMobileSDK-1.01.jar;)
Can't see it does anything. Following other questions and answers on StackOverflow, I edit the android build.xml.
I do this: (because it turns out the -libraryjars in the config file is not being passed throug)
-libraryjars ${project.target.classpath.value};libs/gson-2.1.jar
Still it says the file is multiply defined. If I could get proguard to ignore it then it would not be defined there. So, I try this in the build.xml:
Replace this:
-injars ${project.all.classes.value}
with this:
-injars bin\proguard\original.jar
What happens then?
It works!
So, why do I have to spefify these in the < proguard > element in the android build.xml, and how are I supposed to be able to do this with a config file?
-injars <b>bin\proguard\original.jar</b>
-libraryjars ${project.target.classpath.value}<b>;libs/gson-2.1.jar</b>
Don't specify additional input with -injars or -library jars in any configuration files; the build process already specifies these options for you. You'll only get lots of warnings about duplicate class files.
ProGuard indeed processes your own code together with the libraries. This is how it can significantly reduce the size of the application's code.
I'm developing a JavaFX application using IntelliJ IDEA as the IDE.
So far, everything runs smoothly, I have all my external libs configured and my JavaFX artifact being correctly created.
Now I would like to integrate obfuscation (using Proguard) when the artifact is created.
IntelliJ have a 'Pre-processing' and 'Post-processing' option in artifact's properties where I can define an Ant task to be runned.
But I have no idea how to create that task and tell the compiler my obfuscation options.
Thank you very much in advance for any clues,
Best regards
There are 3 basic ways you do it:
Create a normal proguard.cfg file, and reference it from ant
Put your proguard settings directly inside ant using XML notation
Put your proguard settings directly inside ant using the proguard.cfg format
Here's a basic example of using Proguard with Ant with the 3rd approach:
http://www.reviewmylife.co.uk/blog/2007/10/20/proguard-eclipse-ant-buildxml/
The important thing to remember about Proguard is that everything you want to obfuscate has to be inside a JAR file, and you'll need to explicitly tell it not to obfuscate certain things (like your program entry point, things you access via reflection, etc).
JavaFX creates a file used as an entry point you want to prevent obfuscating:
-keepclasseswithmembers public class com.javafx.main.Main {
public *; public static *;
}
Make sure to include Java/JavaFX libs
-libraryjars "${java.home}/lib/rt.jar"
-libraryjars "${java.home}/lib/ant-javafx.jar"
-libraryjars "${java.home}/lib/jfxrt.jar"
If you're using FXML files, you'll want to make sure your FXML files are renamed similarly to their respective controller file:
-adaptresourcefilecontents **.fxml
Anything annotated with #FXML is accessed through reflection, so don't obfuscate them:
-keepclassmembernames class * {
#javafx.fxml.FXML *;
}
The Proguard website has a lot of information, but it can be difficult to grok.
Honestly, there are plenty of examples on the web that show you how to do this. Just google javafx proguard, and you'll probably find some good complete examples.
Edit: as far as how IntelliJ passes information to Ant.. I don't know. There are probably some variables it passes in that you reference like a normal Ant propertly. I'm sure JetBrains website has info on that on their website if you can't find it on the net.
If it was me, I'd just create an ant script to compile my application without obfuscation, then add in proguard once you've got that squared away.
Just some complementing information, regarding running an Ant task in idea's 'post-processing'.
Make sure you have a 'default' target. Else the task wont execute. Example of build.xml:
<?xml version="1.0"?>
<project name="ant_task" default="obfuscate" basedir=".">
<target name="obfuscate">
<taskdef resource="proguard/ant/task.properties"
classpath="/opt/proguard5.2.1/lib/proguard.jar" />
<proguard configuration="proguard.cfg"/>
</target>
</project>
I have been developing a couple of NetBeans modules in parallel using the NetBeans IDE. Yesterday (Dec. 12, 2012) the IDE updated and now I can not get any of them to manifest when I run the platform. The platform loads up with no errors but my modules do not appear. If I attempt to explicitly enable them I get:
java.lang.IllegalArgumentException: Not all requested modules can be enabled: [StandardModule:com.foo jarFile: D:\bar.jar]
at org.netbeans.ModuleManager.enable(ModuleManager.java:1024)
I see that the module.xml file looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<nbm>
<!--
<moduleType>autoload</moduleType>
<codeNameBase>com.foo/1</codeNameBase>
<licenseName>Apache License, Version 2.0</licenseName>
<licenseFile>license.txt</licenseFile>
-->
</nbm>
This is all auto-generated and it looks to be commented out, but it looks like it was attempting to set the module as an autoload module. This is odd because it looks to me like the module is behaving as an autoload module.
So my question, which seems like it should be simple but I can't seem to figure out, how do I explicitly define the type of a module?
I think, that problem may be between module dependencies.
Open your module project
Remove all module dependencies
Check your selected NB platform (or change)
Add all your module dependencies
Clean and build and install your module again
I want to store development vs production connection strings and configuration strings in a monodroid project. I would normally store it as app settings in a web.config or an app.config, but how should I do it in monodroid and monotouch projects? I would also like for it to switch configurations automatically between debug and release builds just as visual studio does with *.config files. In an iOS app I could store these in a plist but I'd like a cross platform solution in mono.
How would I do this in monodroid or monotouch?
You should just use a static class with #if declarations.
Something like:
public static class Configuration {
#if DEBUG
public const string ConnectionString = "debug string";
#else
public const string ConnectionString = "release string";
#endif
}
The benefit to using app.config is the ability to change these settings on the file system without recompiling. On mobile, there isn't a good way (especially on iOS) to edit the file after it's deployed. So it's generally better to just use a static class and redeploy when you need to change the values. This will also work on all platforms, because it is just C# code doing the work.
there's a Xamarin centric AppSetting reader available at https://www.nuget.org/packages/PCLAppConfig
it is pretty useful for continuous delivery;
use as per below:
1) Add the nuget package reference to your pcl and platforms projects.
2) Add a app.config file on your PCL project, then as a linked file on all your platform projects. For android, make sure to set the build action to 'AndroidAsset', for UWP set the build action to 'Content'. Add you settings keys/values: <add key="config.text" value="hello from app.settings!" />
3) Initialize the ConfigurationManager.AppSettings on each of your platform project, just after the 'Xamarin.Forms.Forms.Init' statement, that's on AppDelegate in iOS, MainActivity.cs in Android, App in UWP/Windows 8.1/WP 8.1:
ConfigurationManager.Initialise(PCLAppConfig.FileSystemStream.PortableStream.Current);
3) Read your settings : ConfigurationManager.AppSettings["config.text"];
