Notification bar icon turns white in Android 5 Lollipop

I have an app showing custom notifications. The problem is that when running in Android 5 the small icon in the Notification bar is shown in white. How can I fix this?

The accepted answer is not (entirely) correct. Sure, it makes notification icons show in color, but does so with a BIG drawback - by setting the target SDK to lower than Android Lollipop!

If you solve your white icon problem by setting your target SDK to 20, as suggested, your app will not target Android Lollipop, which means that you cannot use Lollipop-specific features.

Have a look at http://developer.android.com/design/style/iconography.html, and you'll see that the white style is how notifications are meant to be displayed in Android Lollipop.

In Lollipop, Google also suggest that you use a color that will be displayed behind the (white) notification icon - https://developer.android.com/about/versions/android-5.0-changes.html

So, I think that a better solution is to add a silhouette icon to the app and use it if the device is running Android Lollipop.

For instance:

Notification notification = new Notification.Builder(context)
            .setAutoCancel(true)
            .setContentTitle("My notification")
            .setContentText("Look, white in Lollipop, else color!")
            .setSmallIcon(getNotificationIcon())
            .build();

    return notification;

And, in the getNotificationIcon method:

private int getNotificationIcon() {
    boolean useWhiteIcon = (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP);
    return useWhiteIcon ? R.drawable.icon_silhouette : R.drawable.ic_launcher;
}

Completely agree with user Daniel Saidi. In Order to have Color for NotificationIcon I'm writing this answer.

For that you've to make icon like Silhouette and make some section Transparent wherever you wants to add your Colors. i.e,

You can add your color using

.setColor(your_color_resource_here)

NOTE : setColor is only available in Lollipop so, you've to check OSVersion

if (android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
    Notification notification = new Notification.Builder(context)
    ...
} else {
    // Lollipop specific setColor method goes here.
    Notification notification = new Notification.Builder(context)
    ...
    notification.setColor(your_color)
    ...            
}

You can also achieve this using Lollipop as the target SDK.

All instruction regarding NotificationIcon given at Google Developer Console Notification Guide Lines.

Preferred Notification Icon Size 24x24dp

mdpi    @ 24.00dp   = 24.00px
hdpi    @ 24.00dp   = 36.00px
xhdpi   @ 24.00dp   = 48.00px

And also refer this link for Notification Icon Sizes for more info.

This is the code Android uses to display notification icons:

// android_frameworks_base/packages/SystemUI/src/com/android/systemui/
//   statusbar/BaseStatusBar.java

if (entry.targetSdk >= Build.VERSION_CODES.LOLLIPOP) {
    entry.icon.setColorFilter(mContext.getResources().getColor(android.R.color.white));
} else {
    entry.icon.setColorFilter(null);
}

So you need to set the target sdk version to something <21 and the icons will stay colored. This is an ugly workaround but it does what it is expected to do. Anyway, I really suggest following Google's Design Guidelines: "Notification icons must be entirely white."

Here is how you can implement it:

If you are using Gradle/Android Studio to build your apps, use build.gradle:

defaultConfig {
    targetSdkVersion 20
}

Otherwise (Eclipse etc) use AndroidManifest.xml:

<uses-sdk android:minSdkVersion="..." android:targetSdkVersion="20" />
