Android :: Is IPv6 Over Wifi Interface Supported In SDK?
Apr 20, 2010
I'm hearing that IPv6 is supported by android, at least over the wifi interface, but I cannot do anything with IPv6 through the SDK at all. I am running Android 2.1 on an N1. I can see that at the OS level, the wifi interface has a link local inet6 address: ufo:~ newton$ adb shell $ cat /proc/net/if_inet6 0000000000000 0000000000000000001 01 80 10 80 lo fe80000000000000022376fffe8d1e63 0c 40 20 80 eth0 although ifconfig does not show it: $ ifconfig eth0 eth0: ip 192.168.1.2 mask 255.255.255.0 flags [up broadcast running multicast] If in Java I call getInetAddresses on a java.net.NetworkInterface, I only get the inet4 address. As I'd expect from the above, I cannot connect via any Java APIs to another link local IPv6 host on the same wifi lan Depending on my approach I get "socket level is invalid", a bad socket options error, host unreachable, or timeouts.

It seems the java.net.NetworkInterface implementation of android does not have a byte[] getHardwareAddress() method http://developer.android.com/reference/java/net/NetworkInterface.html
I've found several forums of people trying to do this with no definitive answer, I need to get a somewhat cross-device UUID, so I can't rely on phone numbers or in ANDROID_ID (which can be overwritten and which I think depends on the user having a google account http://developer.android.com/reference/android/provider/Settings.Secure.html#ANDROID_ID
In linux you can use ifconfig or read from /proc/net/arp and you can easily get the Hardware address.
Is there a file in android that I can read?
There has to be a way to get this address since it's shown in the "Settings > About Phone > Status" of the phone.

I'm trying to connect from a host (PC or other) to a mobile cellular Android device on the Verizon/AT&T cellular network. This device uses only the 3G network and has its Wi-Fi turned off. The Android device has a listening socket and I need the remote host to be the connection initiator. As far as I know, Verizon/AT&T uses NAT traversal for mobile phones and assigns local IP addresses to them on the cellular network. This prevents me from initiating a connection to the device from a remote host.
With the usage of IPv6 assignments there shouldn't be any practical limitation (virtually unlimited) to the number of "real" IPs that can be assigned.Therefore my questions are:
1. Does the Verizon/AT&T cellular network support IPv6 and assigns IPv6 addresses to capable Android devices?
2. Does Android 2.2+ have enough support for IPv6 to implement such solution?
I am aware of other methods that can be used, such as C2DM, but it has some drawbacks (such as unknown response time) that prevent me from using it.

Assuming the following:
Android 2.3.7 device is connected to an IPv6 internet connection
Tethering is legal for your device/carrier
The ipv6-test gives 10/10 (perfect score) for IPv6 readiness for your phone, and you can access e.g. [URL] ..... using the phone itself
You want to tether to a PC using USB
Device is rooted
Is there a way to give the PC access to the phone's IPv6 internet connection?
I'm assuming that we can't give the PC a public IPv6 address, because the phone is probably only allotted one IPv6 address from the carrier; plus they might treat your plan differently or something if you try to claim another IP address (it's an unnecessary complexity)
So what we actually need to do is, to create a NAT IPv6 space on the device, just like we do for IPv4 when we tether, and provision an IP to the PC that way. Then we have to do something for DNS; I guess we can use OpenDNS's AAAA servers.
Do any of the existing tethering methods support this at all, or is this something I'd have to do manually? Also, is it possible even in theory on Android 2.3, or is it known that a newer version of Android will enable it?

I don't know if real Android system can support IPv6 protocol stack. I compiled my own kernel with IPv6 configured as "build-in" and then tested it under the emulator in SDK, and it could not get an IPv6 address. I got "No IPv6 router present" in dmesg. I think it may be the emulator's fault. Has anyone ever tested IPv6 in a real Android device?

I'm having hard times getting my GL thread (from GLSurfaceView) to trigger some code execution within the UI thread (from Activity). I tried it in every possible way (well not every, I missed at least the good one) none worked.
My idea was to get something called from the UI thread (to update some widgets) when the surface is effectively created. So I added to my onSurfaceCreated method the following call:
CODE:.............
This compiles, but when my GLSurfaceView sub-class is constructed a NoClassDefFound exception is thrown, telling me that the class com.my.package.MyGLSurfaceView$1 is not found.
Here's the log:
CODE:.............
The line 297 in MySurfaceView.java is:
private Runnable mUpdater = new Runable () { public void run () { [...] } };

I am building an app for Android 2.1 that provides notifications based on calendar events. But I'm aware there are issues with the Calendar API not being readily available / stable / whatever. What I'd like to do is somehow communicate with the user's Google Calendar to get a list of tasks every few hours, or perhaps when the calendar is updated, and then store that data locally so they don't need to have an active Internet connection at all times. Then at a particular time, the notification event would occur. Surely, someone must have determined a way to interface with Google Calendar? I'm sure there must be numerous apps and solutions available that connect to it already, and my users can use any interface they like for interacting with it, but I need to be able to read the data and store it locally.

Which do you guys use? Torrent Off: BarTor vs. Torrent Droid. I bought both and forgot to test them out, so I can't refund either. But I want to know which one I should go through the trouble of configuring. What has the nicer interface? Best performance? Does Torrent Droid use the Browser to do all of its torrent searches?

I am looking for some answers from some of the experts here. I have a project in mind that I want to start. It is about using HTC's Touch HD phone as a device in a museum with rich media/video about the art and the artists on it. Besides the videos and animation, I also want to show some content from a web browser. Now my biggestest issue. I do not want that the museum guest who pick up the phone for the tour get to see the standard Android user interface. Is there a way to develop a new user interface that would start up directly once the phone is turned on? It should then automatically start the app with the museum infos. Later I may want to add some GPS functions and even sms and photo taking, etc....
What do you think, how flexible is Android to allow that?

I want to implement a http remote control for an Android application: From a browser on a computer in the local area network the application running on the Android device should be controlled.
Are there any recommendation how to implement this? I heard about i-jetty but it is not uncomplex to integrate it into an existing app.

This is probably a very "newbie" question as I'm relatively new to the android sdk, but figured this would be good place to ask.
Say you have a layout with several textviews that all have sequential IDs (ie, tBox1, tBox2, tBox3, etc).Is it possible to reference each box in a loop? Something like:
do { iCount++; View tvBox1 = findViewById(R.id.tBox[iCount]); }

Been using remote interfaces for quite a while now, but the time has come to increase the amount of data i need to pass between processes. Following the Designing a Remote Interface using aidl examples/ tutorial i have had some success but have now come to a problem.
My activity binds to my service no problem, the callbacks work, but the data i send does not reach the client. My code is an extension of "Pass by value Parameters using Parcelables" from the "Designing a Remote Interface using aidl" page. The only difference is the amount of data, it has 18 int's and 3 Doubles. As you will see below, once i have entered the data into the parcel, i create my Parcelable using .createFromParcel(p) this however does not seem to work, even when my Parcelable is reading from the parcel no data gets read.
Here is my code for sending the data to the client.
CODE:..............
Here is my Parecelable:

I have VillainROM 12 installed on my Hero and have been playing around with various themes from the standard Sense UI to things like dxtop. I do want to try out the stock Android UI which I believe is accomplished by just going into Applications>Manage Applications>HTC Sense and selecting clear defaults thus setting it to stock Android. Thing is that in my install of VillainROM 12 the "clear defaults" button is greyed out and unavailable to be pressed. Is this an intentional thing in VR12 or am I maybe going to have to re-flash in order to achieve this?

I have created a service and want to expose the interface to other applications. For one service I have done this successfuly. I just put the AIDL interface into the new project and all worked fine. Now for this service I've done the same but I get a java.lang.VerifyError when trying to use this interface. I think that the problem is that the AIDL uses a class (PolicyRole) that is only defined in the source code of the service. To compile the source that uses the interface I had to link against the code of the service but at runtime the error appears. Code...

In Android, how can I replace the user interface of an emulator by my own interface? I would like to start my own interface immediately as the emulator gets started and that the user can't use the original interface but the original interface is on the background.
Update:
Now my code looks like this...
As I run the program, Eclipse displays
ActivityManager: Warning: Activity not started, its current task has been brought to the front. Does anyone knows why?
