Works fine in the debugging version. But in the released APK, this error occurs.

Hello Nipuna!

This looks like an issue with Android Code Minification.

Please add the following line to your project's "/android/app/proguard-rules.pro" file.

-keep class lk.payhere.** { *; }

If the "proguard-rules.pro" file does not exist, you can simply create one in the project's "/android/app" folder.

After adding a new file, make sure it is included in the project's "/android/app/build.gradle" file as shown below (refer to the two lines after the asterisk marks)

android {
 compileSdkVersion 29

  sourceSets {
    main.java.srcDirs += 'src/main/kotlin'
  }

  lintOptions {
    disable 'InvalidPackage'
  }

  defaultConfig {
    // Android configurations are usually here
  }

  // Signing Configurations are usually here

  buildTypes {
    release {

      signingConfig signingConfigs.debug

      minifyEnabled enableProguardInReleaseBuilds
      // ******** Add the following two lines *********
      useProguard true
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

    }
  }
}
