在启动某些活动之前,小部件无法在 Android 11 上的设备启动时启动服务 [英] Widget can't start a service on device boot on Android 11 until some activity is launched
问题描述
val startServiceIntent = TestService.getServiceIntent(context).let {
PendingIntent.getService(context, 0, it, PendingIntent.FLAG_UPDATE_CURRENT)
}
val views = RemoteViews(context.packageName, R.layout.layout_app_widget).apply {
setOnClickPendingIntent(R.id.start_service_btn, startServiceIntent) // doesn't work on boot device
setOnClickPendingIntent(R.id.start_activity_btn, startActivityIntent) // works fine
}
appWidgetManager.updateAppWidget(appWidgetId, views)
如何对待这种行为?我如何至少向用户显示一条消息,即在他启动应用程序(使其可见)或在此设备会话期间启动活动之前,无法从小部件启动服务?
How to treat such behaviour? How can I at least show a message to a user that a service can't be started from widget until he launches the app (make it visible) or launch an activity instead during this device session?
因为现在我按下按钮启动服务时没有任何反应,直到我至少启动一次应用程序
Because now nothing happens when I press the button to start the service until I launch the app at least once
Android 11 上是否有任何方法可以检查我们是否可以从后台/小部件启动前台服务、相机等?如何确定用户在设备的当前会话中至少启动了一次应用的 Activity?
Is there any method on Android 11 to check if we can start foreground service, camera and so on from background / widget? How to find out that user has launched an activity of app at least once for the current session of the device?
推荐答案
基于@CommonsWare 注释,我需要使用 PendingIntent.getForegroundService()
而不是 PendingIntent.getService()
代码>
Based on @CommonsWare comment I need to use PendingIntent.getForegroundService()
instead of PendingIntent.getService()
