Android restores page status information when returning to the previous page

Android returns to the previous page

Environment : uni-app develops an H5 project, and the H5 project link webview is embedded in the app.
Situation : Android jumps from the page link to enter the map webpage for navigation and then returns to the original page. The original page triggers reloading and refreshes the state; it is hoped that the state can be retained and the reason is not refreshed
. : Android will not get the page from the cache, but IOS will get the page from the cache.
Solution : Android cannot be controlled to refresh the page, and the page can only be restored by storing page information.

1. Store information when jumping to navigation

openLocation(e) {
    
    
    const {
    
     latitude, longitude, address } = e.currentTarget.dataset;

    if (latitude && longitude) {
    
    
        // #ifdef H5
        uni.setStorageSync('activeTab', this.activeTab)
        let url = `https://apis.map.qq.com/tools/routeplan/eword=${
      
      address}&epointx=${
      
      latitude}&epointy=${
      
      longitude}?referer=${
      
      应用名称}&key=${
      
      腾讯地图的key}`
        window.location.href = url
        // #endif
        // #ifdef MP-WEIXIN
        uni.openLocation({
    
    
            latitude: Number(latitude),
            longitude: Number(longitude),
            name: address || ''
        });
        // #endif
    }
},

2. Restore the page when reloading

// 从地图导航中返回上级页面与重新进入该应用的情况是高度相似的，该应用进入过地图导航的情况下路由历史history的长度会增加，通过该值进行判断是否需要还原页面
created() {
    
    
	console.log('new store created');
    // #ifdef H5
    let tab = uni.getStorageSync('activeTab')
    if(history.length == 2 && tab !== undefined) {
    
    
        this.setData({
    
    
            activeTab: tab
        });
        uni.setStorageSync('activeTab', undefined)
    }
    // #endif
}
