4.2 Branding Mobile Apps (Advanced-Edition License Only)

As the built-in Port 8443 administrator, you can brand your Filr mobile apps to match your organization’s brand.

IMPORTANT:Direct Port 8443 administrators do not have rights to administer branding.

4.2.1 Android UI Branding

To custom brand the Android Filr app, you must first create a folder on your system that will be used to hold the resources used for custom branding. We will refer to this as the android-branding folder in the rest of this document.

You can customize the colors and the images that Android uses to customize the filr app. Let’s deal with the images first and then the colors.

Customizing Images for Android Branding

About Image Density

Because Android runs on devices with a wide variety of screen densities, you should always provide bitmap resources tailored to each of the generalized density buckets: low, medium, high and extra-high density. This will help in achieving good graphical quality and performance on all screen densities. If for some reason, you can’t provide images for all of the density buckets, then you must provide at least one image matching the XXXHDPI/XXHDPI/XHDPI scale factor. The higher resolution image, the better the display quality.

First start with a base image and then generate the images for each density using the following scale table. Remember in Android, 1dp (device independent) is equal to 160 pixels.

Density Bucket Name

Scale Factor




160 x 0.75 = 120 pixels



160 x 1 = 160 pixels



160 x 1.5 = 240 pixels



160 x 2 = 320 pixels



160 x 3 = 480 pixels



160 x 4 = 640 pixels

For example, if you create a 75x75 image for LDPI then you need to create the following images to match other densities.

Density Bucket Name

Density Scale

0.75 – Base Image

0.75 x 0.75


1.0 - 100

100 x 100


1.5 – (100 x 1.5) - 150

150 x 150


2.0 – (150 x 2) - 200

200 x 200


4.0 – (200 x 3) - 600

600 x 600


HDPI6.0 – (600 x 4) - 2400

2400 x 2400

Creating and Naming the Images

Filr Android-app customizing involves the following branding images.

Table 4-2 Android Image Names and Default Sizes

Image Name

Location Where Displayed

Recommended Dimension Ratio*


This image is shown on the passcode lock screen.

144 x 144 pixels


This image is shown on the login screen.

775 x 144 pixels


This image is shown next to the up button.

475 x 96 pixels

* Images that conform with the ratios shown will render without distortion in the locations indicated. For example, an ic_launcher.png image that is 288 X 288 pixels will render without distortion.

Create the following folder/folders in the android-branding folder that you created on your system. You don’t have to create all folders matching different scaling factors. You can create one generic folder called “drawable” and place higher resolution images in this folder. This higher resolution image will be scaled dynamically by Android to make it look good on different Android devices. Providing a lower resolution image will not yield satisfactory results.

Table 4-3

Folder Name



Place all lower resolution images here


Place all base resolution images here


Place all high resolution images here


Place all extra high resolution images here


Place all extra extra high resolution images here


Place all extra extra extra high resolution images here


Place the highest possible resolution images here. Images placed here may not be required to be placed in other folders. Images placed in this folder are dynamically scaled by Android to make them look good on various devices.

Customizing Colors for Android Branding

To customize the colors in Filr’s Android mobile app, create a file called colors.xml in the android-branding folder and add the colors with your chosen values. Filr’s Android app supports customizing the following colors.

These two colors are used for creating a gradient shade that is applied to the header bar. This change is visible only in the What’s New section.



These two colors are used for creating a gradient shade that is applied to the header bar. This change is visible throughout the UI, except in the What’s New section and on the main page where the tabs are shown.


This color is used for list-header text. It is visible in the Share-action dialogs.


This color is used in the Add Comments dialog.


This color is used to display links and text.

Example content of the colors.xml file:


NOTE:The custom-branding-resource subsystem is very stringent in interpreting hex codes. You must specify the fully valid color hex code including the pound sign (#). If you miss specifying this sign, then the color value is ignored and default color hex code is used. The supported formats are #FFFFFF and #FFFFFFFF

Select the colors.xml file and the drawable... folders in your android-branding equivalent folder and create a zip archive. Store the zip archive somewhere on your system for use when configuring the branding on the Android client.

To apply the branding you have created, see Using the Mobile App Branding dialog in the Filr 3.4.1: Administrative UI Reference.

4.2.2 iOS UI Branding

To brand your iOS mobile devices, you create a .zip file that includes branding images and color specifications, as described in the following sections.

Tips and Caveats

The following points apply to iOS branding files:

  • Inclusion of any of the customized branding files is optional.

    The iOS app will work fine whether or not they are found in the .zip file.

  • If a file is in the zip file it will be used.

    Otherwise, the default Micro Focus branding displays.

  • Files must be named exactly as specified or iOS applications will not find them.

  • All image files should be set to 72 PPI (pixels per inch). Increasing the resolution beyond this can negatively affect app performance.

iOS Color Customization Details

The FilrBranding.xml file defines the colors displayed. Examples are included after the XML sample below.

<?xml version="1.0"?>

Hex values are valid as well as the colors defined in the iOS UIColor class such as red, blue, yellow, etc. They can be defined in upper, lower or mixed case.

An example would be <ViewHeaderColor>green</ViewHeaderColor>.

There are two valid values for StatusBarTextColor: “dark” and “light”.

The following are examples.

Figure 4-8 Example 4

Creating an iOS Branding .zip File

To apply custom branding to the iOS client, you create the image files for the dialogs you want to brand and define banner and other colors, as follows:

  1. Create .png files for the dialogs that you want to brand.

    Example files are contained in the downloadable iOS-branding-sample.zip file.

    To support optimal image scaling on multiple devices, Micro Focus recommends that you follow the imaging naming conventions outlined in the iOS Human Interface Guidelines published by Apple.

  2. Define the colors you want to use in banners and so on, by creating a FilrBranding.xml file.

  3. Compress the files that you have created into an arbitrarily named .zip file.

  4. Upload the .zip file using the instructions in Branding the Mobile Apps (Advanced-Edition License Only) in the Filr 3.4.1: Administrative UI Reference.

4.2.3 Windows Phone Branding

You can download a sample Windows app branding .zip file here.

Settable Colors

  • LoginFontColor

  • ApplicationBackgroundColor

  • ApplicationFontColor

  • AppbarBackgroundColor

  • AppbarForegroundColor

  • StatusBarBackgroundColor

  • StatusBarForegroundColor

  • DetailsPageBackgroundColor

Customizable Images

You can customze two images that are located on the login page.

The two image must be named as follows:

  • Loginbackground.png (for login page background)

  • Loginheader.png (for login page header)

Assembling and Uploading the Zip File

You can download a sample Windows app branding .zip file here.

After creating your own Windows branding components, do the following:

  1. Zip these three files together and then upload to the server.

    The branding changes are applied on the background thread.

  2. In some cases the branding is not applied properly due to a resource contention.

    Stopping and restarting the app should resolve the issues.

  3. After creating your .zip file, see Using the Mobile App Branding dialog in the Filr 3.4.1: Administrative UI Reference.
