[Android] WebView shouldOverrideUrlLoading ANR

[qoozta]

• adxe version: 1.0.0b6
• devices test on: Google Pixel 4a Android 12
• developing environments
  • NDK version: 24.0.8215888
  • Android Studio version: 2021.1.1 Patch 3
  • cmake version: 3.23.2

Steps to Reproduce:

1. Create a WebView, load a php file which run JS to refresh every 10s.
2. Show a Rewarded Ads (Fluct / Maio SDK), wait the php refresh, then an ANR will occur.

D/Cocos2dxWebViewHelper: https://domain.com/test_refresh.php
D/CocosApp: com.github.anrwatchdog.ANRError: Application Not Responding for at least 5000 ms.
W/System.err: com.github.anrwatchdog.ANRError: Application Not Responding for at least 5000 ms.
W/System.err: Caused by: com.github.anrwatchdog.ANRError$$$_Thread: main (state = WAITING)

W/System.err:     at org.cocos2dx.lib.Cocos2dxWebView$Cocos2dxWebViewClient.shouldOverrideUrlLoading(Cocos2dxWebView.java:133)

If change Cocos2dxHelper.runOnGLThread to activity.runOnUiThread in Cocos2dxWebView.java L129, then the ANR will not occur. It seems the ads make cocos losing the main thread then the CountDownLatch waiting caused an ANR.
