I have a problem about the gamecenter,I am developing a multiply-player game, I have finished the connecting part, good luck, I can connect the another device to play the game over the local wifi, but I tried to do it through the 3G network and external wifi, it didn't work, it appeared that the interface stopped at the view of connecting the counterpart, that means they found each other, but they didn't found the match(maybe).Sometimes, one found the match,another one still stop at the view of connecting, it didn't enter the game, I read the log information, that told me the expected number of players was one, that mean there was only one player entered the game,another one did not, the max number was two.I found many website, but no answer, maybe is that because of the sandbox? I have tried in ios5 vs ios5,ios5 vs ios6 ,ios6 vs ios6,

I'm a bit of a newbie, so bare with me, please.
So long story short, I've been thinking about being hacked a lot lately, probably due to a (very well made) documentary I watched recently - this might be paranoid, but it is what it is.
I was browsing 9gag today when me opening a new tab redirected me to a reCAPTCHA page to prove I'm not human and it said one of the possible reasons was that my IP was changed. And so my quest for truth began. I ran a batch of the sites I've visited through the McAfee WebAdvisor and it claimed they're all safe. I've been running F-Secure on my computer and it hasn't found any issues so far.
So I did a bit of reading and tried to find how many devices are using my Wi-Fi - I read that the arp -a command gives you the IP's of devices using your Internet and that switching them 1 by 1 will result in the number of IP's decreasing by 1. And this is the problem - the amount of devices was the same regardless of whether my phone's Wi-Fi was turned on or off. Is that good, bad or doesn't even matter? Also, how can I efficiently find if there's an external connection to the network at home/my computer/my phone without using ARP
I'm trying to educate myself a bit more on the topic to avoid such panic thoughts so any tips and any help will be much appreciated. Also, apologies for the long post, but I thought that the whole story would show a more clear picture.
My power button died on my phone. Or got less and less responsive. Last time I was lucky that trying a long time I managed to start up my phone. Since then I kept my phone on perpetually or restarting it if that was required. However, now my phone just suddenly turned off out of nowhere. I tried to turn it on again but had no luck. I had previously turned on USB debugging since I thought that was enough to turn it on from the pc if it ever got turned off. Now it seems that was not enough as it shows up as unauthorized in adb (I never tried actually connecting, very stupid on my part). Is there any hope for turning my device on through adb.
Phone: Nokia 7.1
There are some questions on problems with unauthorized devices (ADB Android Device Unauthorized) but those seem to assume I can still turn on my phone to change settings. Is it impossible otherwise?
tldr; Here is a detailed list of instructions if you want to try your luck with fastboot. Your touchscreen and volume buttons must be functional for this to work.
Make sure the phone is turned off.
Press and hold the Volume Down button. Don't release it.
Plug in a USB charging cable
When the screen turns on and shows a message saying "Download" or "Fastboot" mode, release the Volume Down button.
Charge your phone like this for 2 minutes, to make sure it has enough charge.
Move your phone's USB cable and connect it to a PC.
Download the binary for fastboot.
Run fastboot continue.
I have a door telephone on our office building. When somebody presses the button it calls a telephone number for which we have a simcard. Right now that simcard is in a cellphone. Everytime we have a meeting at our office, we have to pick up the phone and press 3 to open the door. I'm looking for a solution to be able to programatically pick up the phone and press the 3. Does any such software exist? I have googled but found nothing.
TLDR; I need some software (and a sim card reader) that can programmatically pick up the phone when it rings and respond with a 3 on the numpad.
The OS doesn't matter.
Not sure if Stackoverflow is the right place to ask. Let me know if you have suggestions for other better places to ask.
You could try using the SIM Card in a normal 3G USB Dongle and an application called "Gammu" which can answer a call and sendDTMF codes i.e. number presses. I have only used Gammu on linux systems but I believe it works on Windows as well.
Another possible solution:
Setup voicemail for that SIM card, and when you are asked to leave your voicemail message (the message which is played to whoever gets to the voicemail) just press the button #3.
When you want, use call forwarding to redirect all calls to the voicemail. Alternatively, turn off the phone (on most cellular networks this will redirect all calls to the voicemail).
I have questions about programming in BlackBerry Devices OS 5 - 7. Is there a listener that can listen if the device is just connected to internet connection? The task of my app is that if the device is connected, it will send a http request right away.
Looking forward to it.
Best regards,
Hammy
The listener you want is called CoverageStatusListener. Have a look at the API: CoverageStatusListener and CoverageStatusListener OS6.0+. Note the two flavours - you might want to use the extended version in your OS 6 and above apps.
But that said, coverage is only 1/2 the story. You might have good coverage but no access to the specific web site you are targeting. Another common problem is things like WiFi Hotspots - you can be talking quite happily on WiFi, but unless you have signed in to the Hotspot, you are not going to be able to communicate with your web site. So the many links that have already been provided by Signare (in the comments for your question), are useful. Here they are again, plus one more that I think is useful:

When I connect my Arduino Mega ADK board to an AOA Android app everything is fine (initially), the connection to the ADK board is fully functional in both directions. However, if the screen rotates, someone hits back, the screen locks, etc, when the app restarts the openAccessory call to the USB manager always returns null. So students have to unplug the USB before the connection can be made again.
I've figured out the problem is related to the Input Stream, because if I don't start the Thread to receive commands then there is no issue. However that's not really a useful fix. :)
My code is here:
https://github.com/ME435/AndroidLibraries_v01/blob/master/src/edu/rosehulman/me435/AccessoryActivity.java
I just subclass my AccessoryActivity in apps like this...
https://github.com/ME435/LED-Toggle/blob/master/src/edu/rosehulman/ledtoggle/LedToggleActivity.java
It's not robust, but it's very simple for students. Thoughts on my issue?
