An overview of the
scenario
Interaction between Android and the front page. The front page has the video playback function. When the video is in full screen, the mobile phone should be supported to control the playback progress by swiping the screen horizontally (fast forward and fast rewind), double-click the screen to pause the video, adjust the brightness of the mobile phone by swiping the left half screen vertically, and adjust the volume of the mobile phone by swiping the right half screen vertically. In this paper, the debugging bridge based on DSBridge without Tencent X5 kernel is used, and the interaction processing is relatively simple. We choose to introduce Tencent X5 kernel into the main Module and replace it with classes under X5 package by using custom WebView, in order to expand the video playback function of WebView. Colleagues have no effect on native and H5 interactions
