App on Android crashed on startup after several build

Hello Gree. Thank you for this awesome works which being maintained by your team! I found this issue regarding the plugin.

I am using Windows 10, Unity 2017.1 for my development environment and Xiaomi Mi4c for my device. At first the plugin worked well, but after I built the app several times (as I can't use this plugin in Windows), it got crashed on startup.

I was using Build and Run from Unity directly to my device (the webview was running while I built the app). After using adb-logcat I found this crash information

strangely after I rebooted my device, the app survived the startup screen and can be played again. I don't really know whether it caused by this plugin or not, but I found this crash happened after I put this plugin into our project. I hope it could help you out.

Thank you!

Reproduce the startup crash with Unity 2017.1 using Build and Run on the Xiaomi Mi4c, then collect the output with adb-logcat. Compare runs with and without the plugin to determine whether it is involved; done means the cause is isolated and the repeated-build startup crash is reliably prevented or documented as external.
