Invalid package identifier when getting bag for resource number 0xffffff

Hi,
I created a popup-menu in my actionbar using a custom action provider. I use API 18.
I have an icon in the right edge of the action bar, if I click this icon my popup menu appears, so far no problem.
If I click the icon, following message appears in the Log:
android log invalid package identifier when getting bag for resource number 0xffffffff
I don't know what this warning means and where it comes from, can someone tell me or give me a hint?
Thans for any help!
Still need help on this topic - please!
is there any idea how to examine the cause of warnings like:
android log invalid package identifier when getting bag for resource number 0xffffffff
What is typically the reason for those warnings? Do I have to do anything or can I leave it like it is?
Thanks for any help!

[Q] mmap error 12 ENOMEM on ZTE Open C

I am porting some native code to run on to Firefox OS. The code runs fine on a Samsung Galaxy S2 mini but when I ran it on ZTE Open C, I am getting an error 12 ENOMEM when I called mmap even with very small number of bytes. Any ideas how to diagnose the problem? How to check whether the kernel is configured to allow mmap operation? Thank you.

Crash and reboot caused by wifi

My wifi is totally dead, phone took too much drops and even logcat shows "E/WifiStateMachine: Failed to load driver" when trying to activate it. I had CM11 official and i upgraded to CM12.1 thinking it would be a software problem, but i got the same behavior.
But things gone worse on CM12.1, there's a bug in Android 5 that crash the system if an invalid wifi config is found, so i can't put the phone in standby because it reboots, error:
Code:
E/wifi: error at line 318: android_net_wifi_getInterfaces null interface array
--------- beginning of crash
E/AndroidRuntime: *** FATAL EXCEPTION IN SYSTEM PROCESS: WifiStateMachine
I see there's a fix for a leaking wifi state in the official S2 CM12.1 thread but this isn't my situation, is there a way to completely disable wifi? I tried the build.prop trick (delete wifi.interface and another) but i still have the wifi button in the dropdown menu, and still reboots on standby. Any suggestion?

[Q] Recovery errors

Hello,
I have just compiled TWRP for my phone, but I got a lots of error, when I booted into the recovery.
I can't see sd card or internal storage when I want to flash something..
There are lots of errors like
"E: invalid block device on '/dev/block/bootdevice/by-name/system........"
" ', 'ext4', 59
E : invalid block device.."
How to fix that?
