sdk：cn.leancloud:realtime-android:6.5.0，6.4.+版本同样有这个问题。
android环境：Xiaomi
代码如下：
this.client = AVIMClient.getInstance(userId); this.client.open(new AVIMClientCallback() { @Override public void done(AVIMClient client, AVIMException e) { if (e == null) { // 成功打开连接 System.out.println("聊天功能建立成功！"); }else { System.out.println("聊天功能建立失败！"+e); } } });
发现开发环境下能够建立聊天，但build release apk后无法连接，如下错误：
