Let’s talk about the Android jump problem of uniapp packaging

With the popularity of mobile Internet, mobile applications have become an indispensable part of people's daily lives. More and more developers and companies are beginning to invest in the development of mobile applications. As a cross-platform development framework, Uniapp has become the first choice of many developers.

In Uniapp development, packaging into an Android application is the developer's final destination. However, during the packaging process, you will encounter some common jump problems. This article will introduce you to the solution to the jump problem encountered when packaging Uniapp into an Android application.

1. Why do you encounter jump problems?

Uniapp uses the grammatical structure of the WeChat applet and processes it for different platforms, so you will encounter some problems when jumping. question.

In the WeChat applet, we can jump to the page through routing, but in Uniapp, we need to convert the routing into a page path. Therefore, in Uniapp, we need to pay attention to maintaining the correctness of the page path, especially when it comes to jumps to subpages, tabbars, and navigation bars.

2. Route jump

In Uniapp, route jump is similar to that in WeChat applet. The uni.navigateTo method is also used to implement page jump. The specific usage method is as follows:

uni.navigateTo({
  url: '/pages/somepage/somepage'
})

Among them, the url parameter represents the page path to jump to. When jumping, you need to keep the page path correct, pay attention to the case and directory structure.

3. Subpage jump

In Uniapp, the subpage jump needs to be prefixed with the page path, for example:

uni.navigateTo({
  url: '/pages/index/index?pageUrl=/pages/subpage/subpage'
})

Among them, pageUrl represents the subpage path.

4. Tabbar jump

In Uniapp, if you need to jump to the tabbar page, you need to use the uni.switchTab method to achieve it:

uni.switchTab({
  url: '/pages/tabbar/tabbar'
})

At the same time, on the tabbar page You need to set the tab bar highlight corresponding to the page path, for example:

{
    "text": "首页",
    "iconPath": "static/tabbar/home.png",
    "selectedIconPath": "static/tabbar/home-select.png",
    "pagePath": "pages/home/home"
}

where pagePath represents the corresponding page path.

5. Navigation bar jump

In Uniapp, if you need to add a jump link to the navigation bar, you need to add the open-type attribute to the navigation bar component, for example:

<uni-nav-bar title="导航栏示例" :show-back="true" :back-text="&#39;返回&#39;" open-type="navigateTo" url="/pages/index/index"></uni-nav-bar>

Among them, navigateTo represents the jump type, and url represents the page path of the jump.

6. Summary

Through the introduction of this article, we learned about the solution to the jump problem encountered when packaging into an Android application in Uniapp. When making route jumps, you need to maintain the correctness of the page path; when making jumps to subpages, tabbars, and navigation bars, you need to pay attention to special processing. I hope this article will be helpful to everyone in order to avoid encountering jump problems in Uniapp development.
