Intent to open the Notification Channel settings from my app

问题

What's the Intent that I need to send to open the settings of a Notification Channel that I've previously created in my app? I need it to link from my settings activity.

To open the settings for a single channel, you can use ACTION_CHANNEL_NOTIFICATION_SETTINGS:

Intent intent = new Intent(Settings.ACTION_CHANNEL_NOTIFICATION_SETTINGS)
        .putExtra(Settings.EXTRA_APP_PACKAGE, context.getPackageName())
        .putExtra(Settings.EXTRA_CHANNEL_ID, yourChannelId);
startActivity(intent);

Using ACTION_APP_NOTIFICATION_SETTINGS will list all channels of the app:

Intent intent = new Intent(Settings.ACTION_APP_NOTIFICATION_SETTINGS)
        .putExtra(Settings.EXTRA_APP_PACKAGE, context.getPackageName());
startActivity(intent);

Here the snippets for the notification settings as well as the granular channel settings:

private void openNotificationSettings() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        Intent intent = new Intent(Settings.ACTION_APP_NOTIFICATION_SETTINGS);
        intent.putExtra(Settings.EXTRA_APP_PACKAGE, getPackageName());
        startActivity(intent);
    } else {
        Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
        intent.setData(Uri.parse("package:" + getPackageName()));
        startActivity(intent);
    }
}

@RequiresApi(26)
private void openChannelSettings(String channelId) {
    Intent intent = new Intent(Settings.ACTION_CHANNEL_NOTIFICATION_SETTINGS);
    intent.putExtra(Settings.EXTRA_APP_PACKAGE, getPackageName());
    intent.putExtra(Settings.EXTRA_CHANNEL_ID, channelId);
    startActivity(intent);
}
