what ?

Steps to reproduce

var peer: WebRTCPeerConnection = WebRTCPeerConnection.new()
peer.initialize({
"iceServers": [ { "urls": ["stun:stun.l.google.com:19302"] } ]
})
peer.session_description_created.connect(self._offer_created.bind(id))
peer.ice_candidate_created.connect(self._new_ice_candidate.bind(id))
rtc_mp.add_peer(peer, id)
if id < rtc_mp.get_unique_id(): # So lobby creator never creates offers.
peer.create_offer()
return peer

When trying to compile and publish all versions of godot 4.0 on Windows to Android, similar errors occur. However, it can run normally on Windows, but I don't know what the reason is

WebRTC插件在Android上无法加载：
在 Windows 上，WebRTC插件可以正常运行，但是在导出到 Android 平台后，插件无法加载。控制台显示以下错误：

vbnet

USER ERROR: Can't open dynamic library: webrtc/lib/libwebrtc_native.android.template_debug.x86_64.so
Error: dlopen failed: library "libwebrtc_native.android.template_debug.x86_64.so" not found.

USER ERROR: Required virtual method WebRTCPeerConnectionExtension::_initialize must be overridden before calling.

我的开发环境：
Godot版本：4.3
操作系统：Windows（开发）/ Android（目标平台）
WebRTC插件：从GitHub下载并手动安装的WebRTC插件

What android device are you testing on?

I see:

USER ERROR: Can't open dynamic library: webrtc/lib/libwebrtc_native.android.template_debug.x86_64.so
Error: dlopen failed: library "libwebrtc_native.android.template_debug.x86_64.so" not found.

Which seems to suggest an x86_64 android device?

The result of running on Android phones and Windows Android emulators is the same, the program cannot load the SO file correctly, but the exe packaged under Windows can run normally

The file fails to load correctly both on the Android system and in the emulator. How can I resolve this issue?

[lcGoodAi]

Does anyone know what the reason is? Could you please let us know?@fabio Alessandrelli
