无法初始化 GeckoRuntime |壁虎视图 | Android

Question

 private fun setupGeckoView() {
        val runtime = GeckoRuntime.create(this) // crashes on this line
        geckoSession.open(runtime)
        geckoView.setSession(geckoSession)
        val url = String(Base64.decode(MYURL, Base64.DEFAULT))
        geckoSession.loadUri(url)
        geckoSession.progressDelegate = createProgressDelegate()
        geckoSession.settings.allowJavascript = true
    }

i call setUpGeckoView methon in onCreat() but when i click back and reopen the app then app crashes with IllegalStateException saying "Failed to initialize GeckoRuntime. It works first time only crashed when i click back and then open app again"

日志如下

Answer 1

如果已经有一个活动的 Gecko 实例运行，将抛出此异常。有很多方法可以解决这个问题。

解决方案 1： 获取给定上下文的默认运行时。

从

更改您的代码

val runtime = GeckoRuntime.create(this)

到

val runtime = GeckoRuntime.getDefault(this)

解决方案 2： 通过完成 activity 退出应用程序时终止进程，将此代码添加到您的 activity.

override fun onDestroy() {
    Process.killProcess(Process.myPid())
    super.onDestroy()
}

解决方案3：只有在没有活动实例的情况下才创建一个新实例运行

private fun setupGeckoView() {
    if (geckoRuntime == null) {
        geckoRuntime = GeckoRuntime.create(this)
    }

    geckoSession.open(geckoRuntime!!)
    geckoView.setSession(geckoSession)
    val url = String(Base64.decode(MYURL, Base64.DEFAULT))
    geckoSession.loadUri(url)
    geckoSession.progressDelegate = createProgressDelegate()
    geckoSession.settings.allowJavascript = true
}

companion object {
    var geckoRuntime: GeckoRuntime? = null
}
