Setting custom factories

You can override a number of defaults through custom factory objects. These can be registered with the Braze SDK as needed to achieve the desired results. However, if you decide to override a factory, you’ll likely need to explicitly defer to the default or reimplement the functionality provided by the Braze default. The following code snippet illustrates how to supply custom implementations of the IInAppMessageViewFactory and the IInAppMessageViewWrapperFactory interfaces.

• java

Custom styles

Braze UI elements come with a default look and feel that matches the Android standard UI guidelines and provides a seamless experience. This reference article covers custom in-app messaging styling for your Android or FireOS application.

Setting a default style

You can see default styles in the Braze SDK’s styles.xml file:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
  <style name="Braze"/>
  <style name="Braze.InAppMessage"/>
  <style name="Braze.InAppMessage.Header">
    <item name="android:layout_height">wrap_content</item>
    <item name="android:layout_width">match_parent</item>
    <item name="android:padding">0.0dp</item>
    <item name="android:background">@android:color/transparent</item>
    <item name="android:textColor">@color/com_braze_inappmessage_header_text</item>
    <item name="android:textSize">20.0sp</item>
    <item name="android:lineSpacingMultiplier">1.3</item>
    <item name="android:gravity">center</item>
    <item name="android:textStyle">bold</item>
    <item name="android:layout_centerHorizontal">true</item>
  </style>

If you would prefer, you can override these styles to create a look and feel that better suits your app.

To override a style, copy it in its entirety to the styles.xml file in your project and make modifications. The whole style must be copied over to your local styles.xml file for all attributes to be correctly set. Note that these custom styles are for changes to individual UI elements, not wholesale changes to layouts. Layout-level changes need to be handled with custom views.

Customizing the font

Braze allows setting a custom font using the font family guide. To use it, override the style for message text, headers, and button text and use the fontFamily attribute to instruct Braze to use your custom font family.

For example, to update the font on your in-app message button text, override the Braze.InAppMessage.Button style and reference your custom font family. The attribute value should point to a font family in your res/font directory.

Here is a truncated example with a custom font family, my_custom_font_family, referenced on the last line:

1
2
3
4
5
6
7
  <style name="Braze.InAppMessage.Button">
    <item name="android:layout_height">wrap_content</item>
    ...
    <item name="android:paddingBottom">15.0dp</item>
    <item name="android:fontFamily">@font/my_custom_font_family</item>
    <item name="fontFamily">@font/my_custom_font_family</item>
  </style>

Aside from the Braze.InAppMessage.Button style for button text, the style for message text is Braze.InAppMessage.Message and the style for message headers is Braze.InAppMessage.Header. If you want to use your custom font family across all possible in-app message text, you can set your font family on the Braze.InAppMessage style, which is the parent style for all in-app messages.

Message dismissals

Disabling back button dismissals

By default, the hardware back button dismisses Braze in-app messages. This behavior can be disabled on a per-message basis via BrazeInAppMessageManager.setBackButtonDismissesInAppMessageView().

In the following example, disable_back_button is a custom key-value pair set on the in-app message that signifies whether the message should allow for the back button to dismiss the message:

• java
• kotlin

  @Override
  public void beforeInAppMessageViewOpened(View inAppMessageView, IInAppMessage inAppMessage) {
    super.beforeInAppMessageViewOpened(inAppMessageView, inAppMessage);
    final Map<String, String> extras = inAppMessage.getExtras();
    if (extras != null && extras.containsKey("disable_back_button")) {
      BrazeInAppMessageManager.getInstance().setBackButtonDismissesInAppMessageView(false);
    }
  }

  @Override
  public void afterInAppMessageViewClosed(IInAppMessage inAppMessage) {
    super.afterInAppMessageViewClosed(inAppMessage);
    BrazeInAppMessageManager.getInstance().setBackButtonDismissesInAppMessageView(true);
  }
});

BrazeInAppMessageManager.getInstance().setCustomInAppMessageManagerListener(object : DefaultInAppMessageManagerListener() {
  override fun beforeInAppMessageViewOpened(inAppMessageView: View, inAppMessage: IInAppMessage) {
    super.beforeInAppMessageViewOpened(inAppMessageView, inAppMessage)
    val extras = inAppMessage.extras
    if (extras != null && extras.containsKey("disable_back_button")) {
      BrazeInAppMessageManager.getInstance().setBackButtonDismissesInAppMessageView(false)
    }
  }

  override fun afterInAppMessageViewClosed(inAppMessage: IInAppMessage) {
    super.afterInAppMessageViewClosed(inAppMessage)
    BrazeInAppMessageManager.getInstance().setBackButtonDismissesInAppMessageView(true)
  }
})

Enabling outside tap dismissals

By default, dismissing the modal using an outside tap is set to false. Setting this value to true will result in the modal in-app message being dismissed when the user taps outside of the in-app message. This behavior can be toggled on by calling:

1
BrazeInAppMessageManager.getInstance().setClickOutsideModalViewDismissInAppMessageView(true)

Customizing the orientation

To set a fixed orientation for an in-app message, first set a custom in-app message manager listener. Then, call setOrientation() on the IInAppMessage object in the beforeInAppMessageDisplayed() delegate method:

• java
• kotlin

1
2
3
4
5
public InAppMessageOperation beforeInAppMessageDisplayed(IInAppMessage inAppMessage) {
  // Set the orientation to portrait
  inAppMessage.setOrientation(Orientation.PORTRAIT);
  return InAppMessageOperation.DISPLAY_NOW;
}

1
2
3
4
5
override fun beforeInAppMessageDisplayed(inAppMessage: IInAppMessage): InAppMessageOperation {
  // Set the orientation to portrait
  inAppMessage.orientation = Orientation.PORTRAIT
  return InAppMessageOperation.DISPLAY_NOW
}

For tablet devices, in-app messages will appear in the user’s preferred orientation style regardless of actual screen orientation.

Disabling dark theme

By default, IInAppMessageManagerListener’s beforeInAppMessageDisplayed() checks the system settings and conditionally enables dark theme styling on the message with the following code:

• java
• kotlin

1
2
3
4
5
6
7
@Override
public InAppMessageOperation beforeInAppMessageDisplayed(IInAppMessage inAppMessage) {
  if (inAppMessage instanceof IInAppMessageThemeable && ViewUtils.isDeviceInNightMode(BrazeInAppMessageManager.getInstance().getApplicationContext())) {
    ((IInAppMessageThemeable) inAppMessage).enableDarkTheme();
  }
  return InAppMessageOperation.DISPLAY_NOW;
}

1
2
3
4
5
6
override fun beforeInAppMessageDisplayed(inAppMessage: IInAppMessage): InAppMessageOperation {
  if (inAppMessage is IInAppMessageThemeable && ViewUtils.isDeviceInNightMode(BrazeInAppMessageManager.getInstance().applicationContext!!)) {
    (inAppMessage as IInAppMessageThemeable).enableDarkTheme()
  }
  return InAppMessageOperation.DISPLAY_NOW
}

To change this, you can call enableDarkTheme at any step in the pre-display process to implement your own conditional logic.

Customizing the Google Play review prompt

Due to the limitations and restrictions set by Google, custom Google Play review prompts are not currently supported by Braze. While some users have been able to integrate these prompts successfully, others have shown low success rates due to Google Play quotas. Integrate at your own risk. Refer to documentation on Google Play in-app review prompts.
