Whenever my app is resuming from lock screen in iOS7, it is getting crashed. The problem is coming mostly in iOS7 devices and it is happening only when the screen is getting locked out automatically. When the I unlock the screen and press any html div or button in the app, the app crashes.
I already tried the solution posted here -
Workaround for PhoneGap, EXC_BAD_ACCESS on getDeviceInfo . It doesn't work.
The Crash log is below -
Exception Type: EXC_BAD_ACCESS (SIGSEGV)
Exception Subtype: KERN_INVALID_ADDRESS at 0xbe4008d4

i think u have a issue when ur app back in foreground from the background ,so it's happens due to when u r trying to access some data or array on background to foreground.that var or array wont accessible or u defined dynamic value thats why it's cause crashed .

I tried to rectify the crash using the crash report under "Windows->Devices->View Device Logs", but the crash log is full of numbers. I tried Re-Symbolicate option, but there is no change. "Exceptional Codes" data is also missing in the report. I'm using single Mac System to run the project and view the crash reports.So there should not be any problem about symbolification Any other way to symbolicate ?

Your app crashes while a UILabel inside a UIScrollView inside an alert is deallocated. I'd suspect that either your app overwrites memory somewhere and this is just a symptom, or you are using some alert in a non-standard way, possibly changing a paragraph style somewhere in the alert in a way that's wrong.
First step would be to turn all reasonable warnings on in the compiler, use the static analyser to find problems, and fix all of them.
I'm looking for some advice or help diagnosing this crash that I am seeing. For the moment, I think it is probably a webkit bug, but anything is possible, so please provide any insight you may have:

I did some further investigation into the stack trace and found the code for Subresourceloader here (https://webkit.googlesource.com/WebKit/+/master/Source/WebCore/loader/SubresourceLoader.cpp).
My guess is that m_resource is NULL at this point marked with (****) causing the crash:
void SubresourceLoader::didReceiveResponse(const ResourceResponse& response)
{
ASSERT(!response.isNull());
ASSERT(m_state == Initialized);
// Reference the object in this method since the additional processing can do
// anything including removing the last reference to this object; one example of this is 3266216.
Ref<SubresourceLoader> protect(*this);
if (m_resource->resourceToRevalidate()) { ****
if (response.httpStatusCode() == 304) {
// 304 Not modified / Use local copy
// Existing resource is ok, just use it updating the expiration time.
m_resource->setResponse(response);
memoryCache()->revalidationSucceeded(m_resource, response);
if (!reachedTerminalState())
ResourceLoader::didReceiveResponse(response);
return;
}
// Did not get 304 response, continue as a regular resource load.
memoryCache()->revalidationFailed(m_resource);
}
...
If it worked after a reinstall then you could try doing the URL request without caching, since I would assume that will give the same outcome:
NSURLRequest *request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:30];
[webView loadRequest:request];
I'm guessing something is going wrong with the caching of a resource.
I occasionally get a crash report which looks like to following:
