[Android] Failed to load libwebrtc.a 's debug symbol

[yifeng zhang]

Hi, I compiled webrtc as static library and use libwebrtc.a in another android native module.  The gn args are:

is_debug=true

symbol_level=2

dcheck_always_on=false

target_os="android"

target_cpu=arm

use_rtti=true

use_custom_libcxx=false

rtc_build_tools=false

rtc_include_tests=false

rtc_build_examples=false

is_component_build=false

rtc_enable_protobuf=false

treat_warnings_as_errors=false

rtc_libvpx_build_vp9=false

rtc_use_h264=true

proprietary_codecs=true

ffmpeg_branding="Chrome"

Linkage show as below:

 libwebrtc.a    ---link into-->  lib****SDK.so

When I native debug lib****SDK.so in Android Studio,  I can use lldb to set breakpoint in webrtc source code, but it didn't hit. Both Step into or direct Run into didn't work.

The lldb breakpoint list show as:

1: file = '/home/*****/Projects/third_party/webrtc-android/src/api/rtc_error.cc', line = 76, exact_match = 0, locations = 0 (pending)

But other cmake-based source or makefile-based source debug symbols work greak like this:

2: file = '/home/*****/Projects/third_party/libwebsockets/lib/core-net/vhost.c', line = 469, exact_match = 0, locations = 1, resolved = 1, hit count = 0

  2.1: where = lib****SDK.so`lws_create_vhost + 24 at vhost.c:469, address = 0xb5f8bf38, resolved, hit count = 0 



I also try to use add-dsym or settings set target.source-map, but these didn't work.

What's wrong with my configuration, Anyone can help?
