Android Setup (Required)

Step 1

CryptoPro SDK is distributed as .aar libraries and must be added manually. Copy folder with .aar files from plugin sources:

android/libs

into your main application Android app folder:

android/app/libs

Step 2

In your application android/app/build.gradle add:

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.aar'])
}

Step 3

In your application android/app/build.gradle add:

Android Gradle Plugin 7.2 and newer

android {
    packagingOptions {
        jniLibs {
            keepDebugSymbols += [
                '*/arm64-v8a/*.so',
                '*/armeabi-v7a/*.so',
                '*/x86_64/*.so'
            ]
        }
    }
}

Android Gradle Plugin 7.1 and older

android {
    packagingOptions {
        doNotStrip "*/arm64-v8a/*.so"
        doNotStrip "*/armeabi-v7a/*.so"
        doNotStrip "*/x86_64/*.so"
    }
}

Step 4

Android Gradle Plugin 4.2.0 and newer

In your application android/app/build.gradle add:

android {
    packagingOptions {
        jniLibs {
            useLegacyPackaging true
        }
    }
}

Android Gradle Plugin 3.3.0 - 8.0

In your application android/gradle.properties add:

android.bundle.enableUncompressedNativeLibs = false

Android Gradle Plugin 3.6.0 - 4.1.0

In your application AndroidManifest.xml:

<application
    android:extractNativeLibs="true">
</application>

Step 5

It is recommended not to use resource optimization, by doing the following:

In your application android/app/build.gradle add:

android {
    buildTypes {
        release {
            shrinkResources false
        }
        debug {
            shrinkResources false
        }
    }
}

In your application android/gradle.properties add:

android.enableResourceOptimizations=false
