Question

我收到了推送通知，并在onMessageReceived中调用了一个活动。

val i = Intent()
i.setClass(this, PreCallActivity::class.java!!)
i.flags = Intent.FLAG_ACTIVITY_NEW_TASK
val callRequest = CallParser.convertRemoteMessageToCallReq(remoteMessage)
i.putExtra(PreCallActivity.EXTRA_CALL_TYPE, "incoming")
i.putExtra(PetZamPubnubService.EXTRA_CALL_REQUEST, callRequest)
startActivity(i)

在onCreate中我设置了一些标志并获得了一个唤醒锁

this.window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN or
        WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD or
        WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED or
            WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON,
            WindowManager.LayoutParams.FLAG_FULLSCREEN or
            WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD or
            WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED or
            WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON)
setContentView(R.layout.activity_pre_call)

val pm = getSystemService(Context.POWER_SERVICE) as PowerManager
wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK, TAG_WAKE_LOCK)
wl?.acquire()

我绑定并启动服务

val intent = Intent(this@PreCallActivity, MyPubnubService::class.java)
startService(intent)
bindService(intent, pubnubServiceConn, Context.BIND_AUTO_CREATE)

我遇到的问题是，当应用程序来自被杀死的手机或显示器已关闭时，我无法访问我的服务并给予我。

kotlin.KotlinNullPointerException

我的问题是，我应该采取哪些具体措施来确保我的服务是从LOCKED / OFF手机正确启动而且应用已被杀死？

我已经测试了以下方案，应用程序运行正常

App in Foreground
背景中的应用
背景和屏幕中的应用程序已锁定/关闭
应用已被杀，屏幕已开启

电话锁定时启动活动时服务不绑定
