[IllegalStateException] Fragment xxx not associated with a fragment manager.

[JulyStar-Lv]

0.2.9版本 fragment流程 A -> B , B ->C, C(popSelf) -> D, D(pop) 回到B， 再从B(pop) 回到A必现闪退 0.2.5版本没有这个问题，由于出现了issue #43 一样的crash，所以升级了版本

我粗略试了下没试出来，方便整理一个简单的demo吗

[JulyStar-Lv]

这两天找时间整理个demo出来。 找了个规避方法，使用下面后退按键方式代替navigator.pop()，就不会出现这个异常了

object NavigationUtils {
    fun clickBack(
        onSuccess: (() -> Unit)? = null,
        onFailed: ((e: Exception) -> Unit)? = null
    ) {
        Thread {
            try {
                val instrumentation = Instrumentation()
                instrumentation.sendKeyDownUpSync(KeyEvent.KEYCODE_BACK)
                onSuccess?.invoke()
            } catch (e: Exception) {
                e.printStackTrace()
                onFailed?.invoke(e)
            }
        }.start()
    }
}

lib_base模块的build.gradle 将'com.github.vitaviva.fragivity:core:0.2.9'改成'com.github.vitaviva.fragivity:core:0.2.5'， 就没问题

还是这个流程 fragment流程 A -> B , B ->C, C(popSelf) -> D, D(pop) 回到B， 再从B(pop) 回到A必现闪退

我看了下 应该是0.2.9版本 D(pop) 回到B时，B没有走onresume流程导致的

找到原因了，库里为了让Fragment走onStart/onStop用了些偏门，所以需要在Activity.onCreate中添加proxyFragmentFactory方法。

class HasLauncherActivity : BaseActivity<EmptyViewModel, ActivityHasLauncherBinding>() {
     ...
    override fun onCreate(savedInstanceState: Bundle?) {
        proxyFragmentFactory()
        super.onCreate(savedInstanceState)
    }
    ...
}
