[android-developers] Re: What happens when i change the kernel config file and build the OS with the changed kernel config file?
Yes, i have read the page and understand that migration to IPv6 when the application is developed in pure JAVA is easy. But i don't know why the Browser uses getaddrinfo(), which is a C function, to deal with IPv6 connection. When we build the OS, we can specify the kernel config file to build against. The "CONFIG_IPV6" is one item in the kernel config file and if it is set, something may read this file and adds/builds an IPv6 module containing the lower layer support for IPv6 connectivity. I would like to know what is doing this and what module(s) are added in order to design a full-functional IPv6 DNS for android. Yes, this page helps me understand IPv6 support in JAVA. I may consider developing IPv6 DNS in pure JAVA~but before that, i think i have to know why getaddrinfo() doesn't work when "CONFIG_IPV6" is not set. Thanks very much.

[android-developers] Re: What happens when i change the kernel config file and build the OS with the changed kernel config file?
I have read the link and understand that migration to IPv6 when the application is implemented in pure JAVA is easy. But (i don't know why) the Browser did not utilize pure JAVA code to deal with the IPv6 connection... When we build the OS, we can specify the kernel config file to build against. The "CONFIG_IPV6" is one item in the kernel config file and if it is set, something may read this file and adds/builds an IPv6 module containing the lower layer support for IPv6 connectivity. I would like to know what is doing this and what module(s) are added in order to design a full-functional IPv6 DNS for android. I have posted the same issue on Android-porting and Android-platform but still not get a satisfying answer. Yes, the link helps me understand how IPv6 is supported in JAVA, so i may consider developing DNS in pure JAVA, thanks!

[android-developers] Re: What happens when i change the kernel config file and build the OS with the changed kernel config file?
Thank you very much, The Browser utilizes a class called InetAddress to deal with Internet address. The InetAddress class further calls getaddrinfo, which is a native method to resolve the URLs. This native method is implemented in C and will throw an exception when it is resolving a IPv6 URL when the "CONFIG_IPV6" is not set.

[android-developers] Re: What happens when i change the kernel config file and build the OS with the changed kernel config file?
The Browser utilizes an JAVA class named InetAddress and this class further calls the "getaddrinfo" native method to resolve the URLs. I am still not sure what reads the changed kernel config file and contributes to the changed behavior of the Browser.apk. Is build/core/ main.mk?

[android-developers] What happens when i change the kernel config file and build the OS with the changed kernel config file?
Hi, everyone~ I have been recently studying on why the Browser in the android OS does not support accessing IPv6 websites through IPv6 URLs. At first, I built the source code with "CONFIG_IPV6" not set and tried IPv6 URLs in the Browser and the Browser could not access IPv6 websites. I then built the source code with "CONFIG_IPV6" set and tried again, the Browser works! But i don't get it. I think the source code of the Browser hasn't been changed, how it can be that the Browser suddenly support accessing websites through IPv6 URLs...? Is it the new kernel config file introduce some modules to be included in the final iso image so that the Browser which utilizes these modules is able to access websites through IPv6 URLs? I just need a hint, such as what reads the changed kernel config file and contributes to the changed behavior of the Browser.apk.

[android-developers] how to remote debug an apk file on the target from the host?
Hello, developers~ i have a host which is a ubuntu server containing the complete source code of android OS. I also have a virtual machine running the android OS image file (i.e, it is a target). I would like to do remote single- step debugging on the Browser.apk in order to see how it calls the DNS resolver to resolve the domain name on the target from the host. i tried gdb and gdbserver, but i seems that it is only suitable for debugging c files. Browser.apk is compiled from java files and files with other extensions so i think jdb isn't suitable for this task as well. anyone could offer me a hint on what tool or approach i should apply? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Where in the source code of the default Browser perform the function of resolving domain name?
i mean, there must be some Java methods or classes employed in the source code of the default Browser on the Android platform to perform the function of resolving domain names to IP addresses. I want to know where are they, or what the exact names of these classes or/and methods are. Point out only one location performing this function is OK, many thanks! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
