I have written a code to save my screen data and retrieve it for second time. Code is:

But, when I packaging it for deploying on iPad, it gives me a error like:
Error occurred while packaging the application:
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
Compilation failed while executing : ADT
I am using Flash builder 4.5 to create iOS application.
Thanx in advance
You need to modify your FlashBuilder.ini file
It's located in your FlashBuilder installation directory.
You need to modify the Xms size - this will allocate more memory while compiling and building project. Remember it should be in strongs of 2.
My file looks like this:
launcher.defaultAction
openFile
-nl
en_US
-vmargs
-Xms256m
-Xmx512m
-XX:MaxPermSize=256m

Unable to get my Xamarin.Android app to fire Toast after boot. I checked many accepted solutions but none seem to resolve my problem. I've also tried various "working" examples but haven't had any luck so clearly I'm missing something.

It would appear that what I want to do is not possible. Once my app is installed the app sits in a stopped state and must be executed manually the first time before it can receive broadcasts

I am trying to manually reconfigure log4j2 at runtime but getting partial success.
Here is the relevant code:
package examples.test;
public class ABCImpl implements XYX{
static Logger logger;
public void initialize(){
LoggerContext ctx = null;
Configuration config = null;
Map mp = null;
ctx = (LoggerContext) LogManager.getContext(false);
config = (Configuration)ctx.getConfiguration();
mp = config.getAppenders();
System.out.println("***<Provider o/p follows> Before logger re-configuration:");
System.out.println("\tAppenders:" + mp.keySet());
//reconfiguration attempt - starts
try{
URI configuration = this.getClass().getResource("/log4j2.xml").toURI();
ctx = Configurator.initialize(this.getClass().getName(), null, configuration);
}catch(Exception e){
System.out.println("\t-------Exception encountered-------");
e.printStackTrace();
}
config = (Configuration) ctx.getConfiguration();
mp = config.getAppenders();
System.out.println("***<Provider o/p follows> After logger re-configuration:");
System.out.println("\tAppenders:" + mp.keySet());
//reconfiguration attempt - ends
logger = LogManager.getLogger(this.getClass().getName());
}
public void myBusinessMethod(){
logger.info("Entry..............");
logger.info("Exit..............");
}
}
This class is actually part of a jar file and am running it inside an application server which guarantees that my initialize method would be called as soon as my class is instantiated.
Here is my log4j2.xml, which I have packed into jar's root:
<?xml version="1.0" encoding="UTF-8"?>
<!-- Don't forget to set system property
-DLog4jContextSelector=org.apache.logging.log4j.core.async.AsyncLoggerContextSelector

<!-- Async Loggers will auto-flush in batches, so switch off immediateFlush. -->
<RollingRandomAccessFile name="Appender1" fileName="servers/${sys:weblogic.Name}/logs/Auditing_${sys:weblogic.Name}.log" immediateFlush="true" append="false" filePattern="servers/${sys:weblogic.Name}/logs/archive/Auditing_${sys:weblogic.Name}-%d{yyyy-MM-dd-HH}-%i.log.gz">

</Async>
</Appenders>

<Logger name="examples.test.ABCImpl" level="info" includeLocation="false" additivity="false">
<AppenderRef ref="Appender1"/>
</Logger>
<Root level="info" includeLocation="false">
<AppenderRef ref="Appender1"/>
</Root>
</Loggers>
</Configuration>
The problem is even though the log file gets created, but nothing gets logged in it. The output in std out that I get is :
ABCImpl.initialize
activeHandlerEntries.length=1
***<Provider o/p follows> Before logger re-configuration:
Appenders:[Console]
***<Provider o/p follows> After logger re-configuration:
Appenders:[Async1, Appender1]
Just to make sure that my log4j2.xml and the piece of code is okay without runtime reconfiguration stuff, if I use -Dlog4j.configurationFile=file:SOME_PATH_OUTSIDE_JAR/log4j2.xml log gets populated as expected.
Please help.
I wondered, if deriving the context for initialization by
ctx = (LoggerContext) LogManager.getContext(false);
may be the problem, since you have to access the "current" context with
ctx = (LoggerContext) LogManager.getContext(true);
according to the Log4j2 API. I would really appreciate a clarification, since i'm trying to programmatically configuring Log4J2, too.
Hours of helpless staring at the code and trying my hands here and there, I found that if I get the Logger from newly initialized context (which is obtained from Configurator.initialize) instead of LogManager, log gets populated with data.
Without this trick, not sure if I needed to call any additional API methods (just after Configurator.initialize) to hook the new context into LogManager so that I could have continued traditional approach of getting Logger from LogManager.
...
config = (Configuration) ctx.getConfiguration();
mp = config.getAppenders();
System.out.println("***<Provider o/p follows> After logger re-configuration:");
System.out.println("\tAppenders:" + mp.keySet());
//reconfiguration attempt - ends
//Following line screwed me up for over three weeks
//logger = LogManager.getLogger(this.getClass().getName());
//workaround:
logger = ctx.getLogger(this.getClass().getName());
}
public void myBusinessMethod(){
logger.info("Entry..............");
logger.info("Exit..............");
}
....

The weird thing is that it worked fine, until at a certain point I kept getting this error, out of the blue. I've been searching for it on Google and Stackoverflow and struck upon a few websites, but none of the answers could help me get any further. It seems this error is also mostly thrown in mobile AIR projects, but mine is a Flash Player project...

The ArrayCollection filling up this renderer is an xml file my own webservice returns. I've tested the file and the use of skillName should be correct in this case.
Do you need to see more code or some more info? Let me know!
I found out I'm dealing with a two dimensional ArrayCollection. I'm not correctly referring to the items in this ArrayCollection, so that's why the properties are not recognized.

Now I have exported application and installed it. After that i changed version on both file AutoUpdate-app.mxml and update.xml(server side) to 2.0.0 . Now i exported the application and dumped it to server (in 'release' folder where update.xml is there.).
Now when i launch the application , Update feature is not working. Its nothing happening.
CheckNow() method is called but doing nothing. Please help me.
I am working on AIR 3.1
Its not giving any kind of error. Only Updation Window is not working.
Please tell me what i m doing wrong. Thanks.
1) trace real version and from update.xml and be sure you did it correct. You must be sure you run old app with 1.0.0 version. BTW, you can use property ApplicationUpdaterUI.currentVersion instead of NativeApplication.nativeApplication.applicationDescriptor
2) You do not listen events after checkNow() calling. Listen all events, like in this article. In
http://thanksmister.com/2009/09/13/custom-air-updater-interface-using-applicationupdater/ (see UpdateManager.as#initialize()):
appUpdater.addEventListener(UpdateEvent.INITIALIZED, updaterEvent);
appUpdater.addEventListener(StatusUpdateEvent.UPDATE_STATUS, updaterEvent);
appUpdater.addEventListener(UpdateEvent.BEFORE_INSTALL, updaterEvent);
appUpdater.addEventListener(StatusUpdateErrorEvent.UPDATE_ERROR, updaterEvent);
appUpdater.addEventListener(UpdateEvent.DOWNLOAD_START, updaterEvent);
appUpdater.addEventListener(ProgressEvent.PROGRESS, updaterEvent);
appUpdater.addEventListener(UpdateEvent.DOWNLOAD_COMPLETE, updaterEvent);
appUpdater.addEventListener(DownloadErrorEvent.DOWNLOAD_ERROR, updaterEvent);
appUpdater.addEventListener(ErrorEvent.ERROR, updaterEvent);
private function updaterEvent(event : Event) : void {
trace(event.type);
}
possible, you missed some thing...
in your server side update.xml you should replace the tag version with versionNumber.
This changed since AIR 2.5.
* Security Sandbox Violation *

I'm not sure exactly what you're trying to do inside the code for image, but my guess is that you're trying to access the loader's content, which is obviously a security violation since the SWF is being loaded from a different domain.
There are two ways to access the content of a SWF that has been loaded from a different domain:
Load the SWF in the "current" security domain
Use Security.allowDomain() in the loaded SWF
