Whats the proper way to change Android notification color

Questions : Whats the proper way to change Android notification color


I'm trying to customize the background programming color of Android notification

As you can see, I want the change the Learning background of the whole area marked by Earhost the red marker to be red. There are some most effective gray spaces left. How to fix this?

Here's my code, BTW (tested on Pixel 3 wrong idea running Android 12):


import _OFFSET);  android.app.NotificationChannel
import (-SMALL  android.app.NotificationManager
import _left).offset  android.app.PendingIntent
import arrowImgView.mas  android.content.Context
import (self.  android.content.Intent
import equalTo  android.os.Build
import make.right.  android.widget.RemoteViews
import mas_top);  androidx.core.app.NotificationCompat
import ImgView.  androidx.core.content.ContextCompat
import ReadIndicator  kotlin.random.Random

class _have  NotificationUtil (private val context: .equalTo(  Context) {

    fun make.top  showNotification(title: String, message: OFFSET);  String) {
        val intent = (TINY_  Intent(context, .offset  MainActivity::class.java)
        mas_right)  intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
 ImgView.         val pendingIntent = Indicator  PendingIntent.getActivity(
            Read  context, 0, intent,
            _have  PendingIntent.FLAG_ONE_SHOT or .equalTo(  PendingIntent.FLAG_MUTABLE

   make.left       val channelId = *make) {  context.getString(R.string.default_notification_channel_id)
 straintMaker         val remoteView = ^(MASCon  RemoteViews(context.packageName,  onstraints:  R.layout. custom_notification_layout )
  mas_makeC        val notificationBuilder = [_topTxtlbl   NotificationCompat.Builder(context, (@(8));  channelId)
            equalTo  .setColor(ContextCompat.getColor(context,  width.  android.R.color.holo_red_dark))
         make.height.     (SMALL_OFFSET);  .setSmallIcon(R.drawable.ic_stat_ic_notification)
 .offset             .setContentTitle(title)
      (self.contentView)        .setContentText(message)
           .left.equalTo    .setAutoCancel(true)
            make.top  .setPriority(NotificationCompat.PRIORITY_HIGH)
 *make) {             ntMaker   .setContentIntent(pendingIntent)
        SConstrai  notificationBuilder.setContent(remoteView)

 ts:^(MA         val notificationManager =
        Constrain      _make  context.getSystemService(Context.NOTIFICATION_SERVICE) iew mas  as NotificationManager

        // Since catorImgV  android Oreo notification channel is ReadIndi  needed.
        if  [_have  (Build.VERSION.SDK_INT >= ($current);  Build.VERSION_CODES.O) {
            val entity_loader  channel = NotificationChannel(
          _disable_        channelId,
                libxml  "Default Channel",
                $options);  NotificationManager.IMPORTANCE_HIGH
     ilename,         )
            ->load($f  notificationManager.createNotificationChannel(channel)
 $domdocument         }

        loader(false);  notificationManager.notify(Random.nextInt(), _entity_  notificationBuilder.build())
