P2P直播模块（pgLibLiveMulti）安卓端编程注意事项。
1.锁屏后如果被系统清理内存了应用也就没有了.
您需要在应用销毁回调里面手动videoStop，并且Clean掉实例。这样做是防止下次登录时可能登录时间太久，因为服务器有退避机制。

@Override protected void onDestroy() { LiveLogout(); super.onDestroy(); } private void LiveLogout() { LiveDisconnect(); if (m_Wnd != null) { m_View.removeView(m_Wnd); pgLibLiveMultiView.Release(m_Wnd); m_View = null; m_Wnd = null; m_Live.Clean(); } } |
2.如果程序没被系统清理强制退出.
在退出到后台时直接disConnect，videoStart。到前台时如果播放端还在线就直接Connect 并videostart，如果播放端不在线了就等待重新上线。此时如果想要马上登录上线，需要手动m_Live.Clean 并 重新调用初始化函数登录 ，登录成功后再打开视频。

public int count = 0; @Override protected void onResume() { if (count == 0) { //Log.v(TAG, "切到前台"); Toast.makeText(MainActivity.this, "切到前台", Toast.LENGTH_SHORT).show(); if (m_bLogin) { m_Live.Connect(m_sDevID); m_Live.VideoStart(m_sDevID, 0, "", m_Wnd); } else { String sInfo = "因为后台放置太久导致掉线，请等待播放端重新上线"; Toast.makeText(MainActivity.this, sInfo, Toast.LENGTH_SHORT).show(); } } count++; super.onResume(); } @Override protected void onPause() { count--; if (count == 0) { Toast.makeText(MainActivity.this, "切到后台", Toast.LENGTH_SHORT).show(); m_Live.VideoStop(m_sDevID, 0); m_Live.Disconnect(m_sDevID); } super.onPause(); } |
3. m_bLogin标志位设置
