I am facing an issue related to WhatsApp sticker implementation. I have used this library I want to check that particular sticker is already added or not in WhatsApp.
How can I achieve this? Please guide me.
I have used below file from this library. isPackageInstalled() function worked for me (Note : I just wanted this functionality only for Android)

**This is jazz.net' offical sample code. My question is how can I set value to "categoryName" in "private static boolean run(String[] args) throws TeamRepositoryException" function.In the Main fuction,there is nothing describing the "arg[]".Who can give me a sample to initial "categoryName" argument. **
The category name argument is something that is defined in the RTC CCM project against the timeline or the project. A sample for this is shown below.
These are the values that are expected in the Category Name Argument.
You can look into your project settings to get this information.
I have coded a simple card game (using IntelliJ 3.3) that updates gui each second and contains many nodes in game which are used to display game events and animation. People who have tried the game said that their system slows down and memory and cpu usage goes up (I was shocked when I saw from one of my friend's screen that it used around 1.4 GB ram) is this supposed to happen?
I have checked some questions related to javaFX memory usage problems but could not relate to my matter. In one article, I read that using many nodes in a JavaFX game might result in high memory usage.
in a short runtime:
minimum memory usage is around 100-250 MB
maximum memory usage is around 800-1200 MB
average memory usage is around 500-700 MB
IMPORTANT:
THERE ARE 100 BUTTONS IN A 10X10 GRIDPANE WHICH DO NOT HAVE FX IDS
in gameButtonClicked matches are found buttons.indexOf(event.getSource())

Compile code fully in memory with javax.tools.JavaCompiler [duplicate]

I want to treat a String as a Java file then compile and run it. In other words, use Java as a script language.

Explanations:
In order to represent a Java source file in memory instead of disk, I defined a StringInputBuffer class in the MemoryJavaFileManager.java.
To save the compiled .class files in memory, I implemented a class MemoryJavaFileManager. The main idea is to override the function getJavaFileForOutput() to store bytecodes into a map.
To load the bytecodes in memory, I have to implement a customized classloader MemoryClassLoader, which reads bytecodes in the map and turn them into classes.
Here is a unite test.

s.executeUpdate("insert into details values('"+id+"','"+name+"''"+contt+"')");
out.print("successfullllll");
} finally {
out.close();
}
}
please check this out.....
This might work only if you are running an emulator on the same machine as the server. Try to replace locahost by 127.0.0.1.
In your connect() method, I can see that you initialized hs as null then you called setRequestProperty. Try to initialize hs properly before calling its methods.
I am trying to create an app that uses the panning and zooming features on the map. I have spent a lot of time trying to implement this. I first tried to create an on touch method inside the MapActivity, but I soon realized it would be a little more than that. I found some code that I tried to implement that created a subclass of a mapview and ran into some issues with it. I need some help with panning around the map. Everywhere I try to clear and display the overlay causes problems. Either the overlays get removed and displayed at the wrong place, or a loop is created causing flashing. Please let me know what I need to do to get this working. I realized that I may need to override the onScroll method if there is one instead of the onTouch method. Right now it is pretty buggy I need some help, so that I can make it bug free. Let me know if my thinking is correct. I need to get this up on the market right away. Here is my code. Thanks in advance.
