准备用到项目中了不知道会不会有性能问题

vitaviva · 2021-01-23T12:18:56Z

嗯，有问题咱们一起解决👊

caojing35 · 2021-01-24T03:47:43Z

我们项目还没用Kotlin额，有没有考虑支持原生Java的基础上，用Kotlin包一层壳，核心还是用Java的？

我看代码里kotlin和Java混用的，有考虑拆分开吗？

vitaviva · 2021-01-24T13:26:02Z

kotlin是趋势，可以低成本地可以针对Java的使用体验做一些兼容，不会用Java进行大规模重构。

很棒的思路，我被navigation搞得头发都掉了，尤其是现在NavGraph像蜘蛛网一样密密麻麻的。后悔用了navigation了

🤝这也是写这个库的初衷

但是也是有性能开销的 1.Activity销毁重建内部的每一个Fragment都会resume 如果fragment太对会卡顿 2.Activity load root fragment之后点击跳转到第二个fragment会有一点卡顿（第一次会卡顿），可能是第一次动态创建文件耗时了导致稍微的卡顿

有人提过相同issue，后期优化

2.Activity load root fragment之后点击跳转到第二个fragment会有一点卡顿（第一次会卡顿），可能是第一次动态创建文件耗时了导致稍微的卡顿

库本身应该没有耗时操作，trace看一下是不是业务层逻辑的问题？

@liukai2530533 恢复重建时的潜在性能问题已修复：#4

升级库之后没有更改任何代码Activity中loadRoot出错
java.lang.RuntimeException: An exception happened in constructor of class com.github.fragivity.MyViewModel

mallxiaodoudou · 2021-02-04T06:35:20Z

我目前只能升级到1.1.3版本。之后的版本就要报上面的错误了

升级到0.1.4 或者0.1.5就会报错 0.1.3可以正常使用

版本问题。

你在app的build.gradle添加下面代码，先临时解决一下吧，我在后面版本里处理一下。

configurations.all {
    resolutionStrategy {
        force "androidx.lifecycle:lifecycle-viewmodel-savedstate:2.3.0-rc01"
    }
}

mallxiaodoudou · 2021-02-04T08:05:43Z

哦那应该是我用的版本低了我指定的是2.2.0
resolutionStrategy.force 'androidx.lifecycle:lifecycle-livedata:2.2.0'

vitaviva · 2021-02-04T08:24:18Z

哦哦。可以去掉force或者提升一下版本吗

mallxiaodoudou · 2021-02-04T08:37:03Z

我先用低版本吧我看我用的2.2.0是官方最高的稳定版本你这要求版本也是有点高哈

vitaviva · 2021-02-04T09:15:29Z

那你先忍耐一下吧，我处理一下

vitaviva · 2021-02-04T14:54:43Z

我先用低版本吧我看我用的2.2.0是官方最高的稳定版本你这要求版本也是有点高哈

0.1.6 已修复
