Hello,

Please add the following snippet to your android/app/proguard-rules.pro file

# --- Keep annotation + inner class attributes ---
-keepattributes Annotation, InnerClasses, Signature
# --- Kotlinx Serialization ---
-dontnote kotlinx.serialization.AnnotationsKt
-keepclassmembers class kotlinx.serialization.json.** {
    *** Companion;
}
-keepclasseswithmembers class kotlinx.serialization.json.** {
    kotlinx.serialization.KSerializer serializer(...);
}
# --- Kotlin Standard + kotlinx packages ---
-keep class kotlin.** { *; }
-keep class kotlinx.** { *; }
-keepclassmembers class **$WhenMappings {
    *;
}
-keepclassmembers class kotlin.Metadata {
    public *;
}
# --- Parcelable Support ---
-keep class * implements android.os.Parcelable {
    public static final android.os.Parcelable$Creator *;
}
-keepnames class * implements android.os.Parcelable {
    public static final ** CREATOR;
}
-keepclassmembers class * implements android.os.Parcelable {
    public static final android.os.Parcelable$Creator *;
}
# --- Retrofit (Square or standard Retrofit2) ---
-keep interface retrofit2.Call
-keep class retrofit2.** { *; }
-keep interface retrofit2.* { *; }
# Keep Retrofit annotations
-keepclasseswithmembers class * {
    @retrofit2.http.* <methods>;
}
# --- Retrofit – Square package (optional but safe) ---
-keep class com.squareup.retrofit2.** { *; }
-keep interface com.squareup.retrofit2.* { *; }
# --- Paystack SDK ---
-keep class com.paystack.android.core.api.** { *; }
-keep interface com.paystack.android.core.api.* { *; }
-keep class com.paystack.android.core.api.models.* { *; }
# Already defined above, but safe to repeat (R8 ignores duplicates)
-keepattributes Annotation

I am facing this same issue. Has there been no solution?

@Tolulope05 If you have added the proguard snippet, make sure to add it to the build types

buildTypes {
        release {
            signingConfig signingConfigs.release
            shrinkResources false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'),
                       'proguard-rules.pro'
        }
        debug {
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'),
                       'proguard-rules.pro'
        }
    }

This is whats shutting down my app when I launch the SDK. I have added the proguard @disparta

[Tolulope05]

Is there no support to this? @damilola-paystack @disparta @gbbest15

[KanmaChizea]

I fixed this by adding this to my build.gradle

dependencies {
     implementation 'com.paystack.android:paystack-ui:0.0.11'
}
