我是Agora.io的新手，我正在为1对1的视频通话创建一个Android应用。我的应用程序一切正常，我可以加入/退出频道，甚至可以通过相机查看自己的本地图像。但是，在通话中，仅音频被传输而视频未被传输。
当我调试应用程序时，可以看到未触发“ onFirstRemoteVideoFrame”事件。我尝试将其更改为“ onFirstRemoteVideoDecoded”（我在许多教程中都看到过，但android studio表示该方法已弃用），但仍无法正常工作。
另外，请注意，当我在proguard-rules.pro文件中添加“ -keep class io.agora。** {;}”行时，它表示找不到该类。所以我改为使用'-keep class io.agora。 {*;}'。
下面是我的活动的Java代码。我正在使用agora 3.1.3。

您可以尝试使用“ onRemoteVideoStateChanged”回调代替“ onFirstRemoteVideoFrame”。
这是代码段：
@Override
public void onRemoteVideoStateChanged(final int uid, int state, int reason, int elapsed) {
super.onRemoteVideoStateChanged(uid, state, reason, elapsed);
if (state == Constants.REMOTE_VIDEO_STATE_STARTING) {
runOnUiThread(new Runnable() {
@Override
public void run() {
setupRemoteVideo(uid);
}
});
}
}
