I'm trying to get the distriqt Adverts extension to work in my AIR app.
On every device that I try my app on, I get that Adverts.service.interstitials.isSupported returns false.
On one device, I also get these Java errors, which is probably the reason why:
Error #2044: Unhandled error:. text=Attempt to invoke virtual method 'java.lang.String com.adobe.fre.FREObject.getAsString()' on a null object reference
Error #2044: Unhandled error:. text=Attempt to invoke interface method 'boolean com.distriqt.extension.adverts.platforms.AdvertPlatform.isInterstitialsSupported()' on a null object reference
I checked and double checked that all required extension are listed in the <extensions> section in the application descriptor xml, and that they are actually included in the APK.
Here is an excerpt of the AS code:
if (Adverts.isSupported)
{
var r:int = GoogleApiAvailability.instance.isGooglePlayServicesAvailable();
if (r == ConnectionResult.SUCCESS)
{
Adverts.service.initialisePlatform(AdvertPlatform.PLATFORM_ADMOB, myAppId);
if (Adverts.service.interstitials.isSupported)
{
// etc...
}
else trace("Interstitials not supported");
What am I doing wrong, or what could I do to find out what I am doing wrong?
(Could not add the adverts tag to this question because not enough reputation)
Check what the value of your myAppId is.
That first error would indicate that it is null and the initialisePlatform() call is failing.

The main File menu for my app has a Share menu, with standard sharing services requested normally through [NSSharingServices sharingServicesForItems:#[self.fileURL]]. It is never called when fileURL is null.
However, this requests outputs the following error:
Could not instantiate class NSURL. Error: Error Domain=NSCocoaErrorDomain Code=4864
"value for key 'root' was of unexpected class 'NSNull'. Allowed classes are '{( NSURL )}'."
The only value contained in the array is self.fileURL, which is of class NSURL. The sharing menu itself works with no problem, and the only problem is this strange error in the console. What am I doing wrong and where might this null value come from?
I followed the official Guide from Typo3 for creating a new extension (https://docs.typo3.org/m/typo3/book-extbasefluid/9.5/en-us/4-FirstExtension/Index.html). But when I finished, the page with the plugin gives me only an ERROR 500. No Error-Log anyway.
When I enabled ErrorDisplay I found, that there was a problem with boolean values. So I deleted them and tried again. Again all I got was ERROR 500. ErrorDisplay said the constructor cannot have a return value - hu?? Found inline 7 - but the declaration is in line 22 -??
public function __construct(int $j = 0, int $n = 0, int $i = 0, int $p = 0, int $y = 0, int $a = 0): void {...}
So I tried to delete the return value. But then it told me, that the class couldn't be found. Next, I tried to find anything about that error but found even less than nothing.
I wasn't even able to find extensions that are implementing the way explained by the official guide. Is there anybody who can tell me, what is going wrong and where I can find a solution - I have no idea anymore.
After hours and hours trial and error I found the solution. The Problem is, that Typo3 doesn't give a proper error message due to failing with the exception handling. You have to enable normal PHP Errors to get a clue what is wrong. If there is any php error, Typo3 fails and gives an reflection error, because it thinks the class isn't available.
First Error was: following the official guide instructions for first extension. Compiler ist failing if you try to give the constructor a return value.
Second Error: Typo3 doesn't recognize if a parameter in constructor is missing. It tries to take the next parameter and fails by comparing the parameters type.
Third Error: If the class is missing the instructions for underlying symphony framework the reflection also fails with registering the class without giving any error message.
After I found and corrected all the errors, all worked fine.
I get this error in my log files every time a cache file doesn't exist it seems. On the first page load, I always get this error
[message] => filemtime(): stat failed for [...]/runtime/cache/my/myapp03eab921185f7b68bbca50d8debc0dda.bin
[file] => [...]/vendor/yiisoft/yii2/caching/FileCache.php
[line] => 113
It doesn't happen anymore on next page loads but that one time is really annoying since the slack bot watcher is spamming our channel with this useless warning. Is there a way to avoid that, or is it a permission problem?
The "runtime", "cache" and "my" folders all have 775.
Update
Turns out the issue is that I'm using error_get_last() that is also getting warning-level errors. So it's a different issue entirely, not Yii-related
Make sure that you don't have enabled scream in your php.ini. Warnings from this filemtime() call should be suppressed by # operator, but scream setting can override this operator and generate warning anyway.
if (#filemtime($cacheFile) > time()) {
// ...
}
You must be getting this in PHP 7.1. try to run this with PHP 5.5 and see if you are getting the same error.
To reproduce you need to delete all files from runtime/cache directory
Then start app again(reload page) and look into runtime/cache. It is empty
Yii2 doesn't make cache again
Got same issue in Yii. The error was on the same string (FileCache.php:113)
if (#filemtime($cacheFile) > time()) {...
In my case reason was that my custom php error handler (heir
of the class yii\base\ErrorHandler) didn't check if
error type need to be handled according error_reporting().
Custom handlers allways gets every error, even muted by Error Control operator (#)
https://www.php.net/manual/en/function.set-error-handler.php
error_reporting() settings will have no effect and your error handler will be called regardless
I'm learning go and trying to understand how to get more detailed error information out of the generic error type. The example I'll use is from the net package, specifically the DialTimeout function.
The signature is
func DialTimeout(network, address string, timeout time.Duration) (Conn, error)
The error type only defines an Error() string function. If I want to find out exactly why DialTimeout failed, how can I get that information? I found out that I can use type assertion to get the net.Error specific error:
con, err := net.DialTimeout("tcp", net.JoinHostPort(address, "22"),
time.Duration(5) * time.Second)
if err != nil {
netErr, ok := err.(net.Error)
if ok && netErr.Timeout() {
// ...
}
}
but that only tells me whether or not I had a timeout. For example, say I wanted to differentiate between a refused connection and no route to host. How can I do that?
Maybe DialTimeout is too high-level to give me that kind of detail, but even looking at syscall.Connect, I don't see how to get the specific error. It just says it returns the generic error type. Compare that to the Posix connect, which will let me know why it failed with the various return codes.
My general question is: how am I supposed to pull out error details from the generic error type if the golang docs don't tell me what type of errors may be returned?
Most networking operations return a *OpError which holds detailed information about the error
and implements the net.Error interface. So for most use cases it is sufficient to use net.Error
as you already did.
But for your case you'd want to assert the returned error to be *net.OpError and
use the internal error:
if err != nil {
if oerr, ok := err.(*OpError); ok {
// Do something with oerr.Err
}
}
As soon as you're doing this you are in the land of platform dependency as syscalls under Linux
can fail differently to those under Windows. For Linux you'd do something like this:
if oerr.Err == syscall.ECONNREFUSED {
// Connection was refused :(
}
The syscall package contains the important error constants for your platform. Unfortunately
the golang website only shows the syscall package for Linux amd64. See here for ECONNREFUSED.
Finding out types
The next time you're wondering what is actually returned by some function and you can't make
heads and tails of it, try using the %#v format specified in fmt.Printf (and friends):
fmt.Printf("%#v\n", err)
// &net.OpError{Op:"dial", Net:"tcp", Addr:(*net.TCPAddr)(0xc20006d390), Err:0x6f}
It will print detailed type information and is generally quite helpful.
I would like to know if the tool "wsdl2java" (Axis2) is able to generate stubs that support getting list of custom ojects.
For instance, if I have a WS that have the following method:
public List<Device> getDevices(){
//...
}
Where Device is a custom class...
This tool can do that?
I changed the return data type of my Web Service to an array because of that:
http://www.ibm.com/developerworks/webservices/library/ws-tip-coding/index.html
And I had to do some changes (some namespaces) to the generated stub (I used ADB)...
I changed that because it was giving me an ADBException: Unexpected subelement ...
