在协程工作线程上出现以下崩溃,此崩溃只会在某些三星、Vivo和Oppo设备上发生,具体而言是在Android 10系统上。
在worker上实现了
Fatal Exception: android.app.RemoteServiceException: Context.startForegroundService() did not then call Service.startForeground(): ServiceRecord{2dcabaa u0 `app_id_hidden`/androidx.work.impl.foreground.SystemForegroundService}

在worker上实现了
doWork
函数,其中init()
函数执行我的任务。override suspend fun doWork(): Result {
setForeground(createForegroundInfo())
return init()
}
private fun init() {
//implementation hidden
}
private fun createForegroundInfo(): ForegroundInfo {
val notificationId = 1
return ForegroundInfo(notificationId, createNotification())
}
private fun createNotification(): Notification {
val context = applicationContext
val builder = NotificationCompat.Builder(context, ChannelType.NOTIFICATION_CHANNEL_GENERAL)
.setContentTitle("Message")
.setSmallIcon(R.drawable.ic_notif_small)
.setOngoing(true)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
createNotificationChannel(
ChannelType.NOTIFICATION_CHANNEL_GENERAL,
ChannelType.NOTIFICATION_CHANNEL_GENERAL
).also {
builder.setChannelId(it.id)
}
}
return builder.build()
}
@TargetApi(Build.VERSION_CODES.O)
private fun createNotificationChannel(
channelId: String,
name: String
): NotificationChannel {
return NotificationChannel(
channelId, name, NotificationManager.IMPORTANCE_LOW
).also { channel ->
notificationManager.createNotificationChannel(channel)
}
}
我没有使用任何位置或麦克风或任何默认的前台服务类型,这是一个简单的工作程序,它执行一些任务。
