Call requires API level 16 (current min is 14): android.app.Notification.Builder#build

Question

The documentation says Notification.Builder is Added in API level 11. Why I get this lint error?

Call requires API level 16 (current min is 14): android.app.Notification.Builder#build

notification = new Notification.Builder(ctx)
                .setContentTitle("Title").setContentText("Text")
                .setSmallIcon(R.drawable.ic_launcher).build();

Manifest:

<uses-sdk
    android:minSdkVersion="14"
    android:targetSdkVersion="17" />

Am I missing something?

Correct me if I am wrong but the API is added in level 11, right? Added in API level 11

Answer 1

NotificationBuilder.build() requires API Level 16 or higher. Anything between API Level 11 & 15 you should use NotificationBuilder.getNotification(). So use

notification = new Notification.Builder(ctx)
                .setContentTitle("Title").setContentText("Text")
                .setSmallIcon(R.drawable.ic_launcher).getNotification();

The tip about the API level needing to be 16 is right. This worked for me

if (Build.VERSION.SDK_INT < 16) {
    nm.notify(MY_NOTIFICATION_ID, notificationBuilder.getNotification());
} else {
    nm.notify(MY_NOTIFICATION_ID, notificationBuilder.build());
}

I was having the problem where the notification worked fine on newer devices but not on Android 4.0.4 (API level 15). I do get a deprecation warning form eclipse. @SuppressWarnings("deprecation") doesn't entirely hide it but I think that is probably helpful.

Android Lint is a new tool introduced in ADT 16 (and Tools 16) which scans Android project sources for potential bugs. It is available both as a command line tool, as well as integrated with Eclipse

If your app supports versions of Android as old as API level 4, you can instead use NotificationCompat.Builder, available in the Android Support library.
