I have a system level app with android:persistent="true", which is pushed to /system/priv-app/ directory. So, it will be auto-install and start its process after reboot. But, when I start my WebActivity to load a web url which contains tag by WebView, it play audio but black screen when press video tag's play button. However, if I remove android:persistent="true", it is ok.
It is confused me very much, cause sdk document never saied android:persistent may lead to that bug, but it happened. Below is the log after I press tag's play button, wish it will be helpful.
