CardField not showing and throwing exception on flutter_stripe 2.1.0, flutter 2.8.1

[aris-1]

Same as #393, but since that is closed and not getting any reply, I opened a new one.

Applied all the requirements at https://github.com/flutter-stripe/flutter_stripe#android, but still not working.
Tried calling applySettings as suggested by jonasbark on above mentioned issue, but that also gives an error.

Using:
flutter_stripe: ^2.1.0
Flutter 2.8.1
ext.kotlin_version = '1.5.0'

Code:

import 'package:flutter_stripe/flutter_stripe.dart';
Stripe.publishableKey = "xxxxxx";
final stripeCardController = CardEditController();

Container(child: CardField(
controller: stripeCardController,
onCardChanged: (card) {
print("onCardChanged1 $card");
},
));

Checked requirements:

• Android 5.0 (API level 21) and above
  minSdkVersion 21

• Kotlin version 1.5.0 and above:
  ext.kotlin_version = '1.5.0'

• Using a descendant of Theme.AppCompat for your activity
  in values/styles.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="LaunchTheme" parent="@android:style/Theme.Black.NoTitleBar">
        <!-- Show a splash screen on the activity. Automatically removed when
             Flutter draws its first frame -->
        <item name="android:windowBackground">@drawable/launch_background</item>
    </style>
    <style name="NormalTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="android:windowBackground">?android:colorBackground</item>
    </style>
</resources>

• Using an up-to-date Android gradle build tools version:

  dependencies {
       classpath 'com.android.tools.build:gradle:4.1.2'  
       classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"  
    distributionUrl=https\://services.gradle.org/distributions/gradle-6.7-all.zip

• Using FlutterFragmentActivity instead of FlutterActivity in MainActivity.kt:

  import io.flutter.embedding.android.FlutterActivity
  import io.flutter.embedding.android.FlutterFragmentActivity 
class MainActivity: FlutterFragmentActivity() { 
}

Could you check if the issue is solved if you add
```await Stripe.instance.applySettings();````
like the example app

flutter_stripe/example/lib/main.dart

Line 13 in e6e9a74

await Stripe.instance.applySettings();

[aris-1]

jamesblasco, when I add
await Stripe.instance.applySettings();
it gives the following:

@aris-1 please update flutter_stripe to the latest version (2.1.1) - you should get more details then

[aris-1]

@jonasbark, I updated flutter_stripe to the latest version (2.1.1), but it's like it is ignoring the MainActivity.kt, where I have put the FlutterFragmentActivity:

MainActivity.kt:

import io.flutter.embedding.android.FlutterActivity
import io.flutter.embedding.android.FlutterFragmentActivity 
class MainActivity: FlutterFragmentActivity() { 
}

Not sure if this is a problem, in AndroidManifest.xml I have:

<application
        android:name="io.flutter.app.FlutterApplication"

Yes indeed, the value in your android manifest is wrong. Change it to your main activity or to flutter fragment activity.

[aris-1]

@jonasbark, I changed the AndroidManifest.xml to point to ".MainActivity" and I get fatal error.

 <application
        android:name=".MainActivity"

Error report:

[jonasbark]

include the java package name where you placed your MainActivity in - '.MainActivity' is referring to the wrong one apparently

[aris-1]

@jonasbark, I believe the AndroidManifest.xml should be something like bellow (removed the android:name="io.flutter.app.FlutterApplication" and the <activity android:name="io.flutter.embedding.android.FlutterActivity")

 <application
    <activity
            android:name=".MainActivity"

but it produces the above mentioned error and I can't find how to fix. Let's say the package name is "com.domain.app". I tried adding it in the name, but still it doesn't find it.

 <application
    <activity
            android:name="com.domain.app.MainActivity"

MainActivity.tk path: android/app/src/main/kotlin/com/domain/app/MainActivity.kt

Error report:

E/AndroidRuntime(19532): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.domain.app/com.domain.app.MainActivity}: java.lang.ClassNotFoundException: Didn't find class "com.domain.app.MainActivity" on path: DexPathList[[zip file "/data/app/com.domain.app-2/base.apk"],nativeLibraryDirectories=[/data/app/com.domain.app-2/lib/arm64, /data/app/com.domain.app-2/base.apk!/lib/arm64-v8a, /system/lib64, /vendor/lib64]]

Can someone please help? Although I have given a response the issue since 9 days still has the label "Awaiting response"

[jonasbark]

I think your question would be better suited on Stackoverflow. To me, it looks like a wrong configuration that is related to Android and not related to this plugin.
Maybe the Kotlin plugin isn't activated on the Android part, thus you're getting the ClassNotFoundException?
