Android Google maps api not loading on my app

The error message is:
Network error. Please try again later.
Any idea why it's possibly not loading on my phone. Everything seems to be updated and good.

Assuming your device has a network connection, I would assume it's because you don't have the android.permission.INTERNET permission declared in your manifest.

How can I trace if WhisperPush in Cyanogenmod 11 is working?

I recently installed Cyanogenmod 11 Pepper on my Xperia sola phone. Happily, CM 11 natively supports Short and Media Message Service encryption. I found this very convenient.
Because of this reason I immediatly registered in WhisperPush (pre-installed app with CM11). It all went fine and I got my TextSecure verfication code via SMS.
1. Do I have to do additional steps after receiving that TextSecure verification code?
I tried to text my gf who's using TextSecure but she could not initiate a encrypted session with me. If she tries to do so, I receive the key but nothing more.
2. How I can verify from within the CM "Messaging" App if encryption is working? (is there a flag of something)
Thx in advance and all the best,

"2. How I can verify from within the CM "Messaging" App if encryption is working? (is there a flag of something)"
I believe that there is currently no way of telling whether the message is encrypted or not and this is something that the devs are working on. IMHO this is terrible for a system that boast high security.

Create a socket in android code(not in android application) getting Permission Denied

I am trying to open a socket in the android source code. Specifically, right now, I am in the DisplayDevice.cpp file, but the location of the socket code may change. Right now after I do:
int fd = socket(AF_INET, SOCK_STREAM, 0);
fd gets returned as -1, and when i check the error message it is listed as Permission Denied. I have looked around a lot for this, most answers involve adding the internet permission to the AndroidManifest file. This will not work for me as the code I am adding is inside of the android source code.
I was wondering if there is a way to bypass the permission denied. Or if there is a better way to do this/ a different type of socket to use(right now I am using sockets from
Thank you.

It is quite natural that you get Permission Denied error. This is simply because you don't have correct permission :). Check out android permission model!
Imagine a scenario like a normal user in an operating system and you write a program which tries to open a socket like yours. You would most probably face the same problem, depending on where the named socket is to be created.
As you are trying to create the socket in DisplayDevice.cpp (compiling android from the source), you may be interested in compiling the source as a superuser. Here is a solution posted by m-ric (I have never tested it).

Sending DTMF tones over the uplink in-call

I'm working on a project that requires my app to be able to send DTMF tones on the voice's uplink frequency during an active call.
My 2 conditions are:
We don't use a customized Android platform
We don't need to root the phone
I've spent several days doing my homework and am aware that in-call DTMF sending is not supported by the current SDK/standard APIs. However, by using the relevant classes in com.android.internal.telephony I am hoping to mimic how the native Phone app does this. I followed this site on how to use internal APIs for standard 3rd party apps.
I've also set myself up with the Android OS dev environment and am able to run the Phone app in debug mode on an emulator to figure its inner workings.
I tried various ways on a stock standard emulator but the errors I got were:
After trying to install a renamed app based on Phone.apk's source using the sharedUserId of android.uid.phone, I got:
Installation error: INSTALL_FAILED_SHARED_USER_INCOMPATIBLE
No doubt due to the fact I don't have the system cert to sign it.
After trying to write a custom app based on the relevant DTMF tone sending code from Phone.apk's source, I get the following error at setting up the PhoneFactory;
java.lang.SecurityException: Permission Denial: not allowed to send broadcast android.provider.Telephony.SPN_STRINGS_UPDATED.
No doubt due to the fact my app doesn't have the right permissions, although AndroidManifest.xml is setup with the same permissions as Phone.apk.
I'm at a loss as to what else I could try. Does anyone have any suggestions?
Thanks in advance,
Simon.

You've taken an interesting approach, and I commend your efforts. Unfortunately, there are some reserved internal privileges (evidently, such as SPN_STRINGS_UPDATED) that you aren't allowed to use as an app developer, which more or less breaks this approach. You could try removing the area of code causing this, but I'm fairly certain you will run into a blocking problem.
Hence, I'm afraid this is not possible at the moment. There's an open feature request on Android for sending DTMF tones over an existing phone call, but it has been dormant there for almost two years.
I understand that this doesn't resolve your problem, but take note that you can send DTMF tones directly after dialing a number:
Intent i = new Intent("android.intent.action.CALL",
Uri.parse("tel://" + number + "," + dtmfTones));

Simply put, you won't be able to do it without customizing at least the Phone app, which has to run as a system user in order to access the modem. In order to do this, you have to root your phone.
To meet your requirements the only possible solution is to enhance the android platform. We did just that, and already sent in our patches to the AOSP project:
https://android-review.googlesource.com/32820
https://android-review.googlesource.com/32821
We are currently waiting for the Google developers to review and accept our contribution. If you are interested, please let Google know on the various AOSP lists (android-contrib, android-platform). It will hopefully expedite the review.
Best Regards,
Gergely

You can't send DTMF tones during an active call, but you can send them when you "program" them when you initiate the call.

Network Connection

I am trying to call a webservice from an android app (Testing from an Emulator)
Now, i keep on getting "request time failed : java.net.SocketConnection : Address family not supported by protocol"
So, went to 'Browser' app of Android-Emulator and wasn't able to open any website
Also, then wrote a java code (J2SE) for network connection and got a "java.net.ConnectException: Connection timed out: connect"
Then looked here and there and guys had a say that some setting are to be done in eclipse and android-emulator to get the network connection going
Like in one of messages here --> "http://192.9.162.102/thread.jspa?messageID=10631928"
But how and where is what i am looking for ?
Any suggestions ?
Thanks

put this line<uses-permission android:name="android.permission.INTERNET"></uses-permission> in Manifest.xml file. I think it will work for u.
