Recently, I was working on a project involving HTML5 and native interactions. The above log appears during the interaction process.

Prerequisites:

1. An activity has seven screens, each of which corresponds to one fragment, and each fragment corresponds to one webview.

2. This method is executed for every webview.

Mwebview. addjavascriptinterface (New nativehtml5 (getactivity (), "js2java_android ");

Symptom:

1. Click the content on the home page, and the page will return. The log is above.

Solution:

1. An activity only keeps one nativehtml5 object. That is, do not create a new JS interface for every fragment.
