问题描述
我创建了一个显示来电的活动，其中包括接听按钮和挂断按钮。当我收到FCM的通知时，将启动此活动。当应用程序处于前台状态时，当推送通知时，它就可以正常工作。
但是当我将应用程序置于后台（未终止），并且推送通知时，活动未启动。我只会在系统任务栏中看到带有标签，图标和文本的默认通知。
尽管应用程序处于后台状态，但我想打开活动。为此，我使用了.setFullScreenIntent（pendingIntent，true）来引用https://developer.android.com/reference/android/app/Notification.Builder#setFullScreenIntent(android.app.PendingIntent,%20boolean)本文档。
仍然无法正常工作。
也引用了此链接FullScreen Notification
和这个https://developer.android.com/training/notify-user/custom-notification
请让我知道该怎么做？

这是活动课

@SuppressLint("InvalidWakeLockTag")
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_notify)
// These flags ensure that the activity can be launched when the screen is locked.
val window: Window = window
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O_MR1) {

val keyguardManager = getSystemService(Context.KEyguard_SERVICE) as KeyguardManager

intent.flags = Intent.FLAG_ACTIVITY_NEW_TASK
context.startActivity(intent)

我还尝试使用广播接收器来接收通知，但仍然无法正常工作。在接收器活动中注册接收者
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
FirebaseApp.initializeApp(this)
val token = FirebaseMessaging.getInstance().getToken() as? String
FirebaseMessaging.getInstance().token.addOnCompleteListener(OnCompleteListener { task ->
if (!task.isSuccessful) {
Log.w("TAG","Fetching FCM registration token Failed",task.exception)
return@OnCompleteListener
}
// Get new FCM registration token
val token = task.result
// Log and toast
val msg = getString(R.string.msg_token_fmt,token)
Log.d("TAG",msg)
Toast.makeText(baseContext,msg,Toast.LENGTH_SHORT).show()
})
mReceiver = object : broadcastReceiver() {
override fun onReceive(context: Context?,intent: Intent?) {
val myNewActivity = Intent(this@MainActivity,NotificationActivity::class.java)
startActivity(myNewActivity)
}
}
mIntentFilter = IntentFilter("OPEN_NEW_ACTIVITY");
val notificationLayoutExpanded = RemoteViews(packageName,R.layout.activity_notify)
val channelId = getString(R.string.default_notification_channel_id)
val channelName = getString(R.string.default_notification_channel_name)
val defaultSoundUri = ringtoneManager.getDefaultUri(ringtoneManager.TYPE_NOTIFICATION)
val notificationBuilder = NotificationCompat.Builder(this,channelId)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle(getString(R.string.fcm_message))
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setCustomBigContentView(notificationLayoutExpanded)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
// Create channel to show notifications.
val notificationmanager = getSystemService(notificationmanager::class.java)
notificationmanager?.createNotificationChannel(
NotificationChannel(channelId,channelName,notificationmanager.IMPORTANCE_HIGH)
)
notificationmanager.notify(0,notificationBuilder.build())
}
// [START handle_data_extras]
intent.extras?.let {
for (key in it.keySet()) {
val value = intent.extras?.get(key)
Log.d("TAG","Key: $key Value: $value")
}
}
// [END handle_data_extras]
}
override fun onResume() {
super.onResume()
registerReceiver(mReceiver,mIntentFilter);
}
override fun onPause() {
super.onPause()
if(mReceiver != null)
// unregisterReceiver(mReceiver);
mReceiver = null;
}
companion object {
private val LOG_TAG = MainActivity::class.java.simpleName
private const val PERMISSION_REQ_ID_RECORD_AUdio = 22
private const val PERMISSION_REQ_ID_CAMERA = PERMISSION_REQ_ID_RECORD_AUdio + 1
}
}
FirebaseMessagingService的onMessageRecieved函数中的指定接收者
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
Log.d(TAG,"Message Notification Body: " + remoteMessage.getNotification()!!.getBody());
remoteMessage.data.get("notification_data")?.let { sendNotification(it) };
val broadcast = Intent();
broadcast.setAction("OPEN_NEW_ACTIVITY")
sendbroadcast(broadcast)
}
请帮助。严重卡住...
