flutter briantree version 4.0.0 crash in android

[TuanMai777]

Hello, I am using flutter version 4.0.0 I am using method final request = BraintreeCreditCardRequest( cardNumber: '4111111111111111', expirationMonth: '12', expirationYear: '2021', cvv: '123', ); final result = await Braintree.tokenizeCreditCard( tokenizationKey, request, );

I got the error below,

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(error, Unable to find explicit activity class {com.your-company.your-app/com.example.flutter_braintree.FlutterBraintreeCustom}; have you declared this activity in your AndroidManifest.xml, or does your intent not match its declared ?, null, android.content.ActivityNotFoundException: Unable to find explicit activity class {com.your-company.your-app/com. example.flutter_braintree.FlutterBraintreeCustom}; have you declared this activity in your AndroidManifest.xml, or does your intent not match its declared ?

In your code (if you have this as an external dependency) at this location,

flutter-braintree/android/src/main/AndroidManifest.xml

replace the code under application tag to below,

<application>
    <activity android:name=".FlutterBraintreeCustom"
        android:exported="true"
        android:theme="@style/bt_transparent_activity">
    </activity>
    <activity android:name=".DropInActivity"
        android:theme="@style/bt_transparent_activity">
    </activity>
</application>

And then do (for android studio) flutter clean invalidate cache and restart

Hi @BunnyBuddy The issue will probably be the same https://github.com/pikaju/flutter-braintree/issues/153
