Error while building WebRTC for android

[Akshay Shah]

Hi all,

My gn command is like:

   

 if [ "$CONFIGURATION" == "Release" ]; then
        gn gen $OUTPUT_DIR --args="target_os=\"android\" target_cpu=\"$TARGET_CPU_ARCH\" is_debug=false is_component_build=true"
    else
        gn gen $OUTPUT_DIR --args="target_os=\"android\" target_cpu=\"$TARGET_CPU_ARCH\" is_debug=true is_component_build=true"

I am getting following error while building WebRTC source for android. 

This happens only for 32-bit architectures. 64-bit architectures work fine.

Unexpected failure during lint analysis of PeerConnectionClient.java (this is a bug in lint or one of the libraries it depends on)
TypeSystem.getUnannotatedType(TypeSystem.java:180)->TypeSystem.getParameterizedType(TypeSystem.java:242)->TypeSystem.getParameterizedType(TypeSystem.java:261)->LookupEnvironment.createParameterizedType(LookupEnvironment.java:949)

Any help is appreciated. Thanks!

Same for me

[Andrey Grusha]

I encountered this very problem as well. looks like it is worth of filing a bug here: https://bugs.chromium.org/p/webrtc/issues/list

I'm able to compile https://chromium.googlesource.com/external/webrtc/+/5f70d3b5597bbca81b18b5807e12209500286d61 with

gn gen out/android-Debug-component --args="target_os=\"android\" target_cpu=\"arm\" is_debug=true is_component_build=true"

ninja -C out/android-Debug-component

at least. Can you try git pull && gclient sync ?

Henrik, could you try an option is_debug=false ? An error appears in this very case

I got the same Error when I try to compile Android WebRTC 32-bit version with option is_debug=false.

But it can be compiled with option is_debug=true.

And I did not know how to do with it.

Is it a bug ??

See my reply in https://groups.google.com/forum/#!topic/discuss-webrtc/z58I-i1fyn4

This affects Android 32-bit Release builds.

It works for me with args: "is_debug=false dcheck_always_on=true is_component_build=false target_os="android" target_cpu="arm" symbol_level=1"

[hua chai]

Thank you very much.It works with arg:  dcheck_always_on=true.

My gn command is : gn gen out/Default-release --args='is_debug=false dcheck_always_on=true is_component_build=false target_os="android" target_cpu="arm" symbol_level=1'

This page gn-build-configuration has mention that.
