AIR application with Native application crash on iOS because of numFunctionsToTest

[Divyakumar_Jain]

I wrote a simple Hello World AIR Native Extension and have implemented following context initializer

void helloWorldContextInitializer(void* extData, const uint8_t* ctxType, FREContext ctx,

                                  uint32_t* numFunctionsToTest, const FRENamedFunction** functionsToSet)

{

    NSLog(@"Entering ContextInitializer");

    *functionsToSet = _methods;

    NSLog(@"Method list initialized");

    if(numFunctionsToTest != NULL)

    {

        NSLog(@"numFunctionToTest is not null");

        *numFunctionsToTest = (uint32_t)2;

    }

    NSLog(@"Exiting ContextInitializer");

}

My Application crash on iOS device with following message in console.

Dec 29 15:58:41 unknown HelloWorld[24298] <Warning>: Entering ContextInitializer

It seems line following line is cause of the problem.

*numFunctionsToTest = (uint32_t)2;

modified the line to *numFunctionsToTest = 2; still no luck.

It seem the pointer is pointing is not correct.

Following is the Device log if it helps.

Can you try shifting this line:

  *functionsToSet = _methods;

after you have set numFunctionsToTest to 2?

If that doesn't work, can you share the contents of _methods?

It was my mistake in configuration of extension.xml file. Instead of mentioning Extesion Initialization funtion i was using context initialization funtions there. It started working after correcting this problem.

Thanks for all the help.
