Can you take a quick look at #3

[weinixuehao]

it seems not network issues as i have downloaded other dependencies.
Below is a remote repo?

@PrinceP
Thanks!
I used follow command in #3
$ bazel build -c opt --config=android_arm64
--distdir=
--repository_cache=
--keep_going
mediapipe/examples/android/src/java/com/google/mediapipe/apps/facedetectiongpu
success!

I apologize that I forgot to update mediapipe_aar.bzl after MP switching to protobuf 3.11.4 and bazel 2&3.

After making the following changes in mediapipe/java/com/google/mediapipe/mediapipe_aar.bzl, you should be able to build mediapipe AARs.

Although I haven't fully tested the AAR, the protos in classes.jar look good to me.

We will fix this issue in the coming release. Thanks for reporting this.

Thanks! Its working! but still has an error.

@jiuqiant
I am sorry for troubling you, I still have a question but no answer in #608 to wish you to give me an answer or idea. e.g How do you usually debug the c++ code or mixed debugging java and c++？or lldb gdb? or gdblldb in vscode ?

1、bazel build -c dbg ... not working but built tflite working in android studio that using its profile apk or debug feature
2、I have compared the mediapipe_jni.so size by -c opt and -c dbg that is the same.
3、The mediapipe_jni.so have not debug info with nm tool.

[jiuqiant]

If this issue is solved, I am going to close it.
For https://github.com/google/mediapipe/issues/608, we will take a look.
