Customize UI via Source (uiextensions_src) ​

When you need to rebuild or replace UI implementation rather than toggle built-in UI, import the uiextensions_src source project for deep customization.

NOTE

  • This section covers UI Extensions UI customization via uiextensions_src.
  • For scanning and other separate modules, use the same project pattern; resource paths follow each module.
  • This section uses samples/viewer_ctrl_demo as a minimal example: import source → change layouts/resources → run. The same approach applies to your app.

Step 1: Add uiextensions_src to the Project ​

Prerequisites

  • uiextensions_src depends on FoxitRDK.aar. Keep the default SDK layout (both under libs). If you change paths, update uiextensions_src references to FoxitRDK.aar.
  • viewer_ctrl_demo already includes FoxitRDK.aar; add uiextensions_src and switch dependencies.

1.1 Include Source in settings.gradle ​

kotlin
include ':app'
include ':uiextensions_src'
project(':uiextensions_src').projectDir = new File('../../libs/uiextensions_src/')

1.2 Switch Dependencies in app/build.gradle ​

Use uiextensions_src and remove or comment FoxitRDKUIExtensions.aar:

kotlin
dependencies {
    implementation 'androidx.appcompat:appcompat:1.3.1'
    implementation 'com.google.android.material:material:1.4.0'
    implementation 'androidx.multidex:multidex:2.0.1'
    implementation (name: 'FoxitRDK', ext: 'aar')
    // implementation(name:'FoxitRDKUIExtensions', ext:'aar')
    implementation project(":uiextensions_src")
    implementation 'com.edmodo:cropper:1.0.1'
    implementation 'com.microsoft.identity.client:msal:2.2.0'
    implementation(name: 'RMSSDK-4.2-release', ext: 'aar')
    implementation(name: 'rms-sdk-ui', ext: 'aar')
    implementation 'org.bouncycastle:bcpkix-jdk15on:1.60'
    implementation 'org.bouncycastle:bcprov-jdk15on:1.60'

    // RxJava
    implementation "io.reactivex.rxjava2:rxjava:2.2.16"
    implementation 'io.reactivex.rxjava2:rxandroid:2.1.1'
}

Step 2: Change Layouts and Resources (Example: Search Panel Icon) ​

A common approach: edit layout XML and replace drawables.

Find the icon resource (e.g. ic_search_list) in uiextensions_src/src/main/res/layout/search_layout.xml and replace the drawable (e.g. copy ic_search_next.xml over ic_search_list.xml).

Recommended steps:

  • 1) Open the layout

    • Open uiextensions_src/src/main/res/layout/search_layout.xml in Android Studio.
    • Select the button in Layout Editor or search for ic_search_list.

  • 2) Confirm resource name

    • Check android:src, app:srcCompat, android:background, etc.
    • Note the resource name (e.g. ic_search_list).

  • 3) Replace and verify

    • Place a same-name asset under uiextensions_src/src/main/res/drawable*.
    • Rebuild, run the demo, and open the search panel to confirm.

NOTE

This minimal example shows how source customization works. Modify layouts, resources, and logic in uiextensions_src to match your product UI.
