title: There is a random crash problem in the repeated connection of webrtc in Android
body: <p>signal 6 (SIGABRT), code -6 (SI_TKILL)
  There is a random crash when using webrtc on Android, and my personal skills are limited. Please ask who can help me to see where the problem occurs and how to modify it</p>
  <p>Detailed description: Android receives audio and video data on the PC side. When reconnecting for many times, there is a crash from time to time. Specifically, the audio and video are displayed for less than 1 second when the link is connected.</p>
  <p>The log does not specifically indicate what is wrong. The specific error log is as follows:</p>
