Frequently Asked Questions (FAQ)

The following responses are supported solutions to frequently asked questions (FAQ) about the Android SDK. The OneTrust team continuously monitors these inquiries and will make additional FAQ available as they are identified.

  1. Is the SDK encrypted or obfuscated in any way?
    Yes, it is encrypted.

  2. Does the SDK use third-party libraries, external dependencies, or open source libraries?
    Yes, the SDK uses all three.

  3. Does the SDK work with SDK aggregators such as mParticle?
    No, it does not.

  4. What dependencies do I need when initializing Google Ad ID?
    The Google Play Services dependency must be downloaded in order to initialize Google Ad ID support for your Android devices.

  5. Does the Android SDK support Android Support Library?
    No, the Android SDK has several AndroidX dependencies. Android released API Level 28 in August 2018 which introduced AndroidX. This upgrade was declared a ā€œmajor improvementā€ by Android and replaced their legacy Android Support Library. At this time, Android no longer supports Android Support Library.

  6. Does the Android SDK support Activity, FragementActivity, or AppCompatActivity when rendering UIs?
    The SDK supportsFragmentActivity or AppCompatActivity only.
    AppCompatActivity is derived from FragmentActivity and FragmentActivity is derived from Activity.
    To render the UI (bottom sheet fragment) on top of the application's UI, the Android SDK needs to work with FragmentManager. FragmentManager is part of FragmentActivity and AppCompatActivity, thus the SDK's UI needs FragmentActivity or AppCompatActivity.

  7. Does the SDK work when using minifyEnabled true for new releases?
    Many clients obfuscate their apps prior to release to optimize for size, security, and performance. Android supports this via the minifyEnabled setting for release buildTypes.
    We've had some customers raise issues previously with app crashes during their final phase of testing when minifyEnabled is set to true. Most commonly, this is due to app's org.json gradle dependency causing a collision with the OneTrust SDK's org.json dependency used for JSON parsing.
    To resolve this, please add the following to your app's file inside of Gradle Scripts, then re-build the app.

    -keep class org.json.** { *; }
  8. What if the dependencies the SDK uses is an older/different version than the one my app uses and causes a conflict?
    In this instance, you can exclude these dependencies from the SDK and add it explicitly in your app. For example, the SDK uses OkHttp 2.8.1 which introduces vulnerabilities/conflicts with the app. You can exclude this dependency from OneTrust and specify your own.

    implementation ('com.squareup.retrofit2:retrofit:2.8.1') {
            // exclude Retrofitā€™s OkHttp dependency module and define your own module import
            exclude module: 'okhttp'
     implementation 'com.squareup.okhttp3:okhttp:4.10.0'
