Module was compiled with an incompatible version of Kotlin - Easy Fix! 😎

Are you dealing with the dreaded "Module was compiled with an incompatible version of Kotlin" error? 😫 Don't worry, I've got you covered! In this blog post, I'll walk you through common issues and easy solutions to help you get rid of this error and add the email and cardholder name in Stripe without breaking a sweat! 💪

The Scenario 🎯

So, you're working with Stripe, and your client wants you to collect the email and cardholder name. Unfortunately, the Stripe payment UI doesn't provide an option for that in com.stripe.android.view.CardMultilineWidget. Determined to solve this, you decided to update the Stripe version from 14.1.1 to the latest one, 16.8.0. Little did you know, this seemingly innocent update would introduce a whole new problem! 😱

The Error Message 🚨

Upon updating the Stripe version and building your project, you were confronted with this error message:

caches/transforms-2/files-2.1/4541b0189187e0017d23bbb0afebd16a/jetified-kotlin-stdlib-common-1.5.0.jar!/META-INF/kotlin-stdlib-common.kotlin_module: Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.5.1, expected version is 1.1.15.

Common Causes of the Error 🕵️‍♀️

This error typically occurs when you have a mismatch between the Kotlin version used in your dependencies and the Kotlin version expected by the module you're trying to use. In this case, it's likely that the newer version of the Stripe library you're using was compiled with a different version of Kotlin than your project expects.

Easy Solution - Updating Kotlin Versions! ✨

To solve this issue, you have two potential solutions:

Solution 1: Update the Kotlin Version in your Project 🔄

1. Open your build.gradle file.

2. Locate the kotlin-android plugin block.

3. Check the kotlinVersion specified within the kotlin-android block.

4. Update the kotlinVersion to the expected version mentioned in the error message (1.1.15 in this case).

For example, change:

kotlinOptions {
    jvmTarget = '1.8'
    // Other configurations...
}

to:

kotlinOptions {
    jvmTarget = '1.8'
    kotlinVersion = '1.1.15'
    // Other configurations...
}

1. Sync your project to apply the changes.

Solution 2: Update the Kotlin Version in your Dependencies 🔄

1. Open your build.gradle file.

2. Locate the dependencies block.

3. Find the dependency for the Stripe library (e.g., implementation 'com.stripe:stripe-android:16.8.0').

4. Add the Kotlin version that matches the expected version mentioned in the error message as an explicit dependency (e.g., implementation 'org.jetbrains.kotlin:kotlin-stdlib:1.1.15').

For example:

dependencies {
    implementation 'org.jetbrains.kotlin:kotlin-stdlib:1.1.15'
    implementation 'com.stripe:stripe-android:16.8.0'
    // Other dependencies...
}

1. Sync your project to apply the changes.

Adding the Email and Cardholder Name in Stripe 💳

Now that we've tackled the incompatible Kotlin version error, let's move on to adding the email and cardholder name in the Stripe payment UI using com.stripe.android.view.CardMultilineWidget.

To obtain the cardholder name and email, you can use the following code:

val cardMultilineWidget = findViewById<CardMultilineWidget>(R.id.card_multiline_widget)
val email = cardMultilineWidget.email
val cardholderName = cardMultilineWidget.card?.name

Make sure you add appropriate EditText fields in your layout file and assign the CardMultilineWidget to the appropriate ID (e.g., R.id.card_multiline_widget).
