I was building an android icon pack from this Material icon pack template library https://github.com/architjn/MaterialIconPackTemplate in AIDE . The IDE (AIDE) is showing this error "unknown member VERSION_CODE of com.architjn.materialicons.Build.Config " in home fragment .java file located in https://github.com/architjn/MaterialIconPackTemplate/blob/master/app/src/main/java/com/architjn/materialicons/ui/fragments/HomeFragment.java and i am unable to solve this problem. I had tried to fix it by IDE's option create public static final int VERSION CODE and the second option and then saved the file ,it even stopped showing the error before building the app but when i press the run button , while compiling it shows the error again. Please help me to solve this problem.
Just create a file named as BuildConfig.java and add the following code in it -
package your.package.name;
public final class BuildConfig {
public static int VERSION_CODE = 1;
}
Here the value of int should be the value of the Versuon Code of the App...

I get this strange error from Visual Studio 2019 in the XAML editor, but the project compiles, runs and the assignment is actually working:
I get this error in all UserControls containing this expression. In my MainWindow the same logic causes no Problems. root is just the root namespace which is identical to local on the MainWindow. The settings object in App.xaml.cs looks like this:
public static readonly ISettings Settings;
ISettings is a simple interface for the ConfigurationBuilder of Config.Net.
using Config.Net;
using System;
namespace MyApp.Properties
{
public interface ISettings
{
[Option(Alias = "skin")]
string Skin { get; }
[Option(Alias = "cryptoID")]
string CryptoID { get; }
// ...
}
}
Cleaning, rebuilding, restarting, nothing helps to get rid of the message. I keep ignoring it, but I wish to get rid of it, please.
If your program runs correctly and Visual Studio displays the wavy line warning by mistake, you could try do the following settings to not display the warning wavy line.
Uncheck Display Error Curve :
Tools> Options> Text Editor> General >Display Error Curve
You can also reset the settings.
Tools→Import and Export Settings...→Reset all settings.
Well, the message basically explains what's wrong, so I went ahead and created the folder C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE\Logs and gave everyone full permission in the ACL security settings in the property window of the folder. Now Visual Studio stops complaining, although no files are created in the folder anyways.
I don't know why this has to be, but the message is gone eventually.
I am using Java JDK 11.0.8 ("Installed JREs" under Eclipse is set to jdk-11.0.8), Eclipse 2020-06, and Codename One 6.0.0.
I have recently switched from JDK 8 to JDK 11 and noticed that playing sounds option in my app does not work anymore...
Note that I uncheck "Java 8" when I create my app and I am only trying to work things out in the simulator (I am not trying to deploy the app to an actual mobile device).
I want to play a "regular sound" (I want to play a sound from beginning to end, and when it ends I do not need to replay it from the beginning) and also a "looping sound" (the sound should come to its beginning when it ends and hence, I can continuously play it in the background).
Hence I have two questions:
Question1 - About "regular sounds"
I would like to create Media object just once and then re-use it whenever I need to play the same regular sound.
For that purpose I am encapsulating a Media creation inside a class as follows:
public class RegularSound {
private Media m;
public RegularSound(String fileName) {
try{
InputStream is = Display.getInstance().getResourceAsStream(getClass(), "/"+fileName);
m = MediaManager.createMedia(is, "audio/wav");
}
catch(Exception e)
{
e.printStackTrace();
}
}
public void play() {
m.setTime(0);
m.play();
}
}
Then I instantiate the RegularSound object and play it as follows:
mySound = new RegularSound("example.wav");
mySound.play();
Please note that example.wav is copied directly under the "src" directory of my project.
This code used to work with JDK 8, but with JDK 11, I get the following build errors:

Question2- About "looping sounds"
For looping sound I have created another class as follows:
public class LoopingSound implements Runnable{
private Media m;
String fileName;
public LoopingSound(String fileName){
try{
InputStream is = Display.getInstance().getResourceAsStream(getClass(), "/"+fileName);
m = MediaManager.createMedia(is, "audio/wav",this);
}
catch(Exception e)
{
e.printStackTrace();
}
}
public void pause()
{
m.pause();
}
public void play()
{
m.play();
}
public void run() {
m.setTime(0);
m.play();
}
}
But I again get build errors when I instantiate an object of LoopingSound and try to play it...
So could you please let me know how to change code for regular and looping sounds so that I do not receive above-mentioned errors when using JDK 11?
UPDATE
Thanks for the reply #shai-almog. I have installed CEF. But I am receiving some messages on the console in runtime and I can't hear the sound playing... I run the following code:
try {
InputStream is = Display.getInstance().getResourceAsStream(getClass(), "/example.wav");
Media m = MediaManager.createMedia(is, "audio/wav");
m.play();
} catch (IOException e) {
e.printStackTrace();
}
and I receive the following messages on console when I run this code (it throws an exception at the end):

UPDATE 2
I could manually add Open JavaFX 11 to Eclipse and to Codename One app running under Eclipse while using JDK 11 as follows:
Step1) Create JavaFX11 user library under Eclipse
Download JavaFX 11 from https://gluonhq.com/products/javafx/
unzip it -> creates javafx-sdk-11.0.2 folder
Create a User Library: Eclipse -> Window -> Preferences -> Java -> Build Path -> User Libraries -> New.
Name it JavaFX11.
Hit "Add External JARs" and include all the jars under javafx-sdk-11.0.2\lib
Step 2) Add the JavaFX11 library to the project:
Right click on project.
Select Build path -> Configure Build Path
Goto Library tab->Add Library->User Library->Check JavaFX11->Apply and Close
Now, I can hear sounds playing in my Codename One application.
However, I need to run my application from command prompt and regular command line to run the apps does not work anymore (the app cannot find the JavaFX related classes from the command prompt and I get the same errors listed above). So could you please tell me how to modify the command line so that Codename One project that uses JavaFX would run from command prompt?
Here is the regular command line I use:
java -cp dist\Proj.jar;JavaSE.jar com.codename1.impl.javase.Simulator com.mycompany.hi.Main
BTW, I have tried to add javafx.media.jar under javafx-sdk-11.0.2\lib to the classpath (-cp) in the command line, but this did not work...
UPDATE 3
We have solved the issue by using the following command line:
java --module-path C:\javafx-sdk-11.0.2\lib\ --add-modules= ALL-MODULE-PATH -cp dist\Proj.jar;JavaSE.jar com.codename1.impl.javase.Simulator com.mycompany.hi.Main
(where C:\javafx-sdk-11.0.2\lib\ is our )
Thanks!
The TL;DR
Either install CEF as explained here or switch to ZuluFX 11 for your VM.
The explanation:
This used to work until we integrated CEF support we would download JavaFX dynamically for JDK 11 installs but this caused a lot of related problems. So we decided to migrate to CEF, this is still in progress and while it's ongoing JavaFX dynamic download is broken. Once it's done CEF will be auto-installed and this will be seamless again.
This impacts browser component and media which are the two components implemented by JavaFX.
What is the best way to get text ? getText() is not returning the link text in google.co.in
I am trying to get the below text
हिन्दी বাংলা తెలుగు मराठी தமிழ் ગુજરાતી ಕನ್ನಡ മലയാളം ਪੰਜਾਬੀ
For this i wrote the script also,but i get the output like ????.
I don't know why it happens.
can anyone suggest me to get the text.
Below is my script
public class LanguageLinks {
public static void main(String[] args) throws InterruptedException, IOException {
WebDriver driver = new FirefoxDriver();
driver.get("https://www.google.co.in");
List<WebElement> links = driver.findElements(By.xpath("//*[#id='addlang']/a"));
System.out.println(links.size());
for(int i=0;i<links.size();i++){
System.out.println(links.get(i).getText());
}
}
}
Edit note : Added code block to include complete code.
This is nothing to do with Selenium but mismatch in character encoding in Eclipse side. Please apply the following settings:
Go to : Window -> Preferences -> General -> Workspace . In Text file encoding section: Select Other radio, Select UTF-8 from combo -> Click OK button.
After above settings is applied, please re execute the code again. You should see proper texts displayed on the screen.
There's no error message and no indication why it is not displaying the window. The app initialises App.xaml.cs: App() {} and I can step through the App.xaml file. It gets the startup uri and then... silence. No output in the Output window and no unhandled exception and no window, I can't find where to put a breakpoint to debug as it isn't hitting the start of MainWindow.xaml.cs.
Really confused.
This was working 20m ago.
In that time all I did was add Windows.Office.Interop.Outlook reference. I removed the reference and rebuilt but still the same. Would that cause this problem? Has anyone seen this before? Google isn't helping!
EDIT :
App.xaml.cs:
public App()
{
using (var dbContext = new DBEntities())
{
if (!db.Exists())
{
try
{
db.Database.Create();
MessageBox.Show("Database created"); // this is the problem!!
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
}
}
I've added App.xaml.cs, I found that the problem was using a MessageBox to give info (this is still in development!). I'd been meaning to get rid of it and eventually did and my problem went away. This meant I could find relevent Goolge results:
MSDN query and answer for exactly my problem
I will be adding an 'loading window' in between app load and main window load eventually in which I will be able to feedback information using Bindings etc.
Fixed error by removing the MessageBox.Show(..) call. The selected answer from the MSDN URL given in the question states:
"I performed a test based on your description, the applicationi stop at the method : USER32!GetMessageW+0x33, calling USER32!NtUserGetMessage"
I assume this is what was occurring in my case, although I didn't test it.
What happens if you create a new window and set that as the StartupUri?
You also might want to create a new project and make sure that the namespaces referenced in the App.xaml in your existing app haven't somehow been inadvertently edited.
I am having trouble instantiating a view model wich loads an image from Resources.
The line that fails in the assembly I'm testing is:
get { return new ImageSourceConverter().ConvertFromString("pack://application:,,,/Resources/Icons/Commands/DisabledNewSessionIcon.png") as ImageSource; }
the exception is:
Unable to create instance of class
GPAnalysisSuite.Tests.View_Models.Session_Controller.SessionControllerViewModel_NonDefaultConstructorTester.
Error:
System.IO.DirectoryNotFoundException:
Could not find a part of the path
'C:\TGP\GP Analysis
Suite\Application\Tests\TestResults\Paul_PAUL-GP
2011-03-17
11_27_28\Out\Resources\Icons\Commands\DisabledNewSessionIcon.png'..
I have already found a solution to a simular problem and included the following to the TestClass:
[AssemblyInitialize]
public static void InitialisePackageUriHelper(TestContext context)
{
PackUriHelper.Create(new Uri("reliable://0"));
new FrameworkElement();
System.Windows.Application.ResourceAssembly = typeof(App).Assembly;
}
I can see that I need to preserve the Uri of the assembly I'm testing but have no idea how to do it, can anyone help?
I appear to have solved the problem by changing the resource build action from Content to Resource.
Although I have to rebuild the solution everytime I want to run the unit tests this is now workable at least.
