Troubleshooting

Code Obfuscation

Obfuscation is a process of transforming bytecode into a form that is less readable to humans, thereby making reverse engineering more difficult. This process involves removing debugging-related information such as variable tables, line numbers, and renaming packages, classes, and methods. When integrating the Android SDK into an application, failures may occur.

Obfuscation via DexGuard

When obfuscation is performed using DexGuard, if a failure occurs, use the following rules:

-keep class kotlin.coroutines.**
-keep class kotlinx.coroutines.**

-keep class com.facetec.sdk.** { *; }
-keep class com.acesso.acessobio_android.** { *; }
-keep class io.unico.** { *; }

-keep class br.com.makrosystems.haven.** { *; }
-keep class HavenSDK.**{ *; }
-keep class HavenSDK** { *; }

Obfuscation via ProGuard

When obfuscation is performed using ProGuard, if a failure occurs, use the following rules:

-keep class kotlin.coroutines.**
-keep class kotlinx.coroutines.**

-keep class com.facetec.sdk.** { *; }
-keep class com.acesso.acessobio_android.** { *; }
-keep class io.unico.** { *; }

-keep class br.com.makrosystems.haven.** { *; }
-keep class HavenSDK.**{ *; }
-keep class HavenSDK** { *; }

SDK Update - Version 4.3.x

Starting from version 4.4.x of the SDK, Unico began using its own Maven repository to distribute the Android SDK and changed the SDK dependency name, in addition to adjustments to ProGuard and DexGuard rules for clients using the GuardSquare library, as described in the Code Obfuscation section above.

Update the Maven Repository:

Change the Maven repository to the new repository in the project’s build.gradle file. The implementation was previously done as follows:

// Top-level build file where you can add configuration options common to all sub-projects/modules.
allprojects {
    repositories {
        google()
        jcenter()
        maven { url 'https://jitpack.io'}
    }
}

It should now be updated to the new repository:

// Top-level build file where you can add configuration options common to all sub-projects/modules.
allprojects {
    repositories {
        google()
        jcenter()
        maven { 
            url "https://maven-sdk.unico.run/sdk-mobile" 
        }
    }
}

Change the SDK Dependency

Update the SDK dependency to the new dependency in the project’s app/build.gradle file. The implementation was previously done as follows:

/* unico */
dependencies {
    implementation 'com.github.acesso-io:acessobio-android:$version'
}

It should now be updated to the new dependency:

/* unico */
dependencies {
    implementation "io.unico:capture:$version"
}
