HTML5 compatibility of Android browsers

Recently, we developed a college GIS Campus System.

The system found a bug and accessed the webpage in the android browser, so the map could not be displayed. However, it was displayed normally in the iphone and common browsers (firefox, chrome, ie9, and so on.

It took a lot of time to re-release the map, modify server settings, and modify the relevant code.

I accidentally found the system backup 2 or 3 months ago. After the release, I found that the Android phone can be normally displayed. I found that I didn't use any HTML5 technology before.

Later, at Party A's request, manifest was used for offline file storage and localStorage offline map cache.

After testing, we found that the culprit was localStorage. As long as localStorage was used, the map could not be displayed, and manifest had no effect on the program. In this case, it seems that the android browser has a problem with localStorage support. However, you are not sure. You still need to find the relevant information. If you know the similar situation, please leave a message ~~~
