When the notif is displayed, the icon is showed. But when I expand the notification menu, it's a grey icon.
My manifest :
<meta-data
android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="#drawable/ic_notification" />
<meta-data
android:name="com.google.firebase.messaging.default_notification_color"
android:resource="#android:color/transparent" />
For exemple, here in this screenshot, the icon is displayed (the green one) :
But then :
For the android above lollipop OS devices, the notification Icon background color should be grey and should follow the notification icon guidelines provided by android.
If you run the same application in the KitKat the existing works fine.
Anyhow there is a solution,
Notification bar icon turns white in Android 5 Lollipop
But it will not work when your app is in closed state.
Check with the below link for icon design guidelines.
Reference web address. Click here for more Info
NotificationCompat.Builder builder = new NotificationCompat.Builder(getContext(), notificationId+"")
.setContentTitle(getContext().getString(R.string.app_name))
.setContentText(message.getAlert())
.setAutoCancel(true);
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
builder.setSmallIcon(R.drawable.notification_icon_transparent);
} else {
builder.setSmallIcon(R.drawable.notification_icon_color);
}
used two notification icon
1) Transparent background. Example icon : https://i.stack.imgur.com/XlEzp.png
2) Color (generally use 'ic_launcher_icon')

Solved : Problem was in icon background color
Android custom notification's small icon has alway white background. I tried different thing but could not get it work. I tried to use transparent icon. Here is code:
new NotificationCompat.Builder(context, COOK_CHANNEL_ID).
setCustomContentView(presenter.getCollapsedViews())
.setCustomBigContentView(presenter.getExpandedViews())
.setSmallIcon(R.drawable.ic_amazon_alexa)
// .setColor(Color.GREEN)
.setOnlyAlertOnce(true)
.setStyle(new NotificationCompat.DecoratedCustomViewStyle());
I am using Netcore Smartech Android SDK version 2.2.19. I have added the meta-data tag for the notification icon as per their documentation but I am not able to see the icon. Gray square comes in the place of the notification icon.
<meta-data
android:name="SMT_SMALL_NOTIFICATION_ICON"
android:value="#drawable/ic_notif"/>
<!-- I also tried below syntax. -->
<meta-data
android:name="SMT_SMALL_NOTIFICATION_ICON"
android:value="ic_notif.png"/>
Try passing only the icon name as they specified <small_notification_icon_name>. Your code should look like this.
<meta-data
android:name="SMT_SMALL_NOTIFICATION_ICON"
android:value="ic_notif"/>
Also, make sure your icon sizes match with the valid sizes for the notification icon. You can refer to this document.
How can I show same icon while app is on background or foreground? Below I have attached my screenshot
I have used this app icon for my notification
Thanks in advance!
Yes. This does happen. It can be fixed by setting color to the icon ,when the notification is generated from inside the app.
NotificationCompat.Builder(
this,
CHANNEL_ID
)
.setSmallIcon(//your vector)
.setColor(ContextCompat.getColor(this, //color of the icon(mostly this may be
the primary/secondary color that has been set ,according to the theme, in this
case some hex of red)))
To keep it consistent, even for the notification generated in the background, a line can be written in the manifest:
<meta-data
android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="#drawable/(your vector)” />
<meta-data
android:name="com.google.firebase.messaging.default_notification_color"
android:resource="#color/(color of the icon)” />
I was wondering if it's possible to change the statusbar icons colour (not the statusbar colour, colorPrimaryDark)
Let's say I want this statusbar with:
<item name="colorPrimaryDark">#android:color/white</item>
and the icons in black, is it possible?
Thanks.
EDIT:
New in the M developer preview: windowLightStatusBar. Flipping this on
in your theme tells the system to use a dark foreground, useful for
lighter colored status bars. Note the M preview seems to have a bug
where notification icons remain white, while system status icons
correctly change to semitransparent black.

Yes it's possible to change it to gray (no custom colors) but this only works from API 23 and above you only need to add this in your values-v23/styles.xml
<item name="android:windowLightStatusBar">true</item>
#eOnOe has answered how we can change status bar tint through xml. But we can also change it dynamically in code:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
View decor = getWindow().getDecorView();
if (shouldChangeStatusBarTintToDark) {
decor.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
} else {
// We want to change tint color to white again.
// You can also record the flags in advance so that you can turn UI back completely if
// you have set other flags before, such as translucent or full screen.
decor.setSystemUiVisibility(0);
}
}
if you have API level smaller than 23 than you must use it this way.
it worked for me declare this under v21/style.
<item name="colorPrimaryDark" tools:targetApi="23">#color/colorPrimary</item>
<item name="android:windowLightStatusBar" tools:targetApi="23">true</item>
Not since Lollipop. Starting with Android 5.0, the guidelines say:
Notification icons must be entirely white.
Even if they're not, the system will only consider the alpha channel of your icon, rendering them white
Workaround
The only way to have a coloured icon on Lollipop is to lower your targetSdkVersion to values <21, but I think you would do better to follow the guidelines and use white icons only.
If you still however decide you want colored icons, you could use the DrawableCompat.setTint method from the new v4 support library.
SystemUiVisibility flags are deprecated. Use WindowInsetsController instead
the code below sets the color of icons to black (for the light statusbar)
//icon color -> black
activity.getWindow().getDecorView().getWindowInsetsController().setSystemBarsAppearance(APPEARANCE_LIGHT_STATUS_BARS, APPEARANCE_LIGHT_STATUS_BARS);
and the code below clears it(i.e. turns icon color to white for dark statusbar):
//icon color -> white
activity.getWindow().getDecorView().getWindowInsetsController().setSystemBarsAppearance(0, APPEARANCE_LIGHT_STATUS_BARS);
link to docs :
https://developer.android.com/reference/android/view/WindowInsetsController#setSystemBarsAppearance(int,%20int)
Setting windowLightStatusBar to true not works with Mi phones, some Meizu phones, Blackview phones, WileyFox etc.
I've found such hack for Mi and Meizu devices. This is not a comprehensive solution of this perfomance problem, but maybe it would be useful to somebody.
And I think, it would be better to tell your customer that coloring status bar (for example) white - is not a good idea. instead of using different hacks it would be better to define appropriate colorPrimaryDark according to the guidelines
You can do it programmatically with retaining all other system UI visibility flags.
public static void changeStatusBarContrastStyle(Window window, Boolean lightIcons) {
View decorView = window.getDecorView();
if (lightIcons) {
// Draw light icons on a dark background color
decorView.setSystemUiVisibility(decorView.getSystemUiVisibility() & ~View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
} else {
// Draw dark icons on a light background color
decorView.setSystemUiVisibility(decorView.getSystemUiVisibility() | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
}
}
in kotlin you can use following lines
val window = this.window
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
window.statusBarColor = ContextCompat.getColor(this, R.color.white)
WindowCompat.getInsetsController(window, window.decorView).apply {
isAppearanceLightStatusBars = true
}
This is for all those who want to change their application's Notification small icon color can use this setColor method of NotificationCompat.Builder
Example:
val builder = NotificationCompat.Builder(this, "whatever_channel_id")
**.setSmallIcon(R.drawable.ic_notification) //set icon for notification**
.setColor(ContextCompat.getColor(this, R.color.pink))
.setContentTitle("Notification Title")
.setContentText("Notification Message!")
I used two line of code for different status bar color
1st: If status bar color is white then use this line of code to visible the status bar icon:
pingAct.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
2nd: If you use dark color then use this line of code to make visible the status bar icon:
pingAct.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE);
Yes you can change it. but in api 22 and above, using NotificationCompat.Builder and setColorized(true) :
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context, context.getPackageName())
.setContentTitle(title)
.setContentText(message)
.setSmallIcon(icon, level)
.setLargeIcon(largeIcon)
.setContentIntent(intent)
.setColorized(true)
.setDefaults(0)
.setCategory(Notification.CATEGORY_SERVICE)
.setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
.setPriority(NotificationCompat.PRIORITY_HIGH);
