QUIC for Android

[Chao Kong]

Hi All,

I am working on porting QUIC to Android using the source code chromium chromium and proto-quic.
I was able to build the chromium apk for android, then I want to build the "quic-client" for android.
I am following the the approach here  android_build_instructions.
More specifically,
after running "gn args out/Default",
 I insert
"target_os = "android"

target_cpu = "arm"  # (default)
is_debug = true  # (default)"

Then, I run 
"ninja -C out/Default quic_client"

The quic_client can be built. And I use adb push to push the related binary into
a Nexus 5 device.Here are the binaries I push into the "data/local/tmp"

libicui18n.cr.so.TOC              natives_blob.bin
libicuuc.cr.so                    quic_client
libicuuc.cr.so.TOC                quic_server
libnet.cr.so                      snapshot_blob.bin
libnet.cr.so.TOC                  v8_build_config.json
lib_net_unittests__library.cr.so

Then, I run 
"./quic_client --host=my ip address --port=6121 https://www.example.org/"

Previously I have built the "quic-client" and "quic-server" for the linux desktop and tested it.
Now, I still use the "quic-server" for the android "quic-client"

Unluckily, the "quic-client" cannot work on android and the error is in the attachment.

I am wondering if it is possible to port "quic" into "android" by the source code chromium.

In addition, I know that cronet is the library for QUIC on mobile devices. But the quic part is in 
a compiled binary, and I didn't find the source code for the quic binary, is the source code open now?

It is great if I can get help from you! Thanks!

Hi Chao,

The error you sent occurs because toy quit client executable wasn't created for mobile devices.

In order to have quic client successfully running on Android you have to call InitVM function from base/android/jni_android.cc before using any chromium related functionality. See example how to do that in chrome/browser/android/monochrome_entry_point.cc. You can modify net/tools/quic/quic_client_bin.cc or quic_simple_client_bin.cc to include that.

In your case chromium stack is trying to get access to Java security-related functionality to have certificates verified during secure connection establishment process. So the workaround would be to disable certificate checks via --disable-certificate-verification CL argument.

Good luck!
