我正在从flutter小部件启动android前台服务并在android活动中接收广播。我想将收到的消息返回到flutter页面并根据操作打开页面（我从服务触发广播意图）。我总是收到消息，但有时页面没有被推送。任何帮助都将非常有用。谢谢
Android活动
class MyReceiverTest : BroadcastReceiver() {//registered in manifest
override fun onReceive(p0: Context?, intent: Intent?) {
if (intent!!.action != null) {
when (intent.action) {
"action1" -> {
val extras = intent.extras
if (extras != null) {
if (extras.containsKey("message1")) { var msg = extras.getString("message1")
Handler(Looper.getMainLooper()).post {
channel!!.invokeMethod("action1Method", msg)
}
} }
}
"action2" -> {
val extras = intent.extras
if (extras != null) {
if (extras.containsKey("message2")) { var msg = extras.getString("message2")
Handler(Looper.getMainLooper()).post {
channel!!.invokeMethod("action2Method", msg)
}
} }
}
}
}
}
}
