Configuring the Module build.gradle
File

Follow these steps to configure your module build.gradle
file.

In the Android section, add these exclusion rules to your module's build.gradle
file.

ADDITIONAL INFORMATION

android {
 
    ...
     
    packagingOptions {      
         exclude 'META-INF/*'
         exclude 'LICENSE.txt'
         exclude 'asm-license.txt'
    }
}

In order for the app to support Java 11 features, you must set the compatibility levels.

ADDITIONAL INFORMATION

android {
 
    ...
 
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_11
        targetCompatibility JavaVersion.VERSION_11
    }
}

The Tap to Phone Android Solution library publishes a release build type only. The debug build type is not available, so set the

matchingFallbacks

field value to

release

.

ADDITIONAL INFORMATION

android {
 
    ...
 
    buildTypes {
        ...
        debug {
            matchingFallbacks = ['release']
        }
    }
}

Add the required Default UI and Tap to Phone libraries to the Dependencies section of your module's build.gradle
file.

ADDITIONAL INFORMATION

dependencies {
  ...
  // This is the Default UI dependency
  implementation 'io.payworks:paybutton-android:2.82.0'   

  // This is the Tap to Phone dependency
  implementation 'io.payworks:mpos.android.taptophone:2.82.0'    
}
