PlatformException(flutter_stripe initialization failed, The plugin failed to initialize. Are you using FlutterFragmentActivity?

[coder-Aayush]

I am trying to set up a payment using this plugin but can't able to initialize it. I followed the setup instruction for android but facing this issue.

PlatformException(flutter_stripe initialization failed, The plugin failed to initialize. Are you using FlutterFragmentActivity?

Initialization

android/app/src/main/kotlin/com/example/myapp/MainActivity.kt

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

build.gradle

ext.kotlin_version = '1.5.10'

 dependencies {
        classpath 'com.android.tools.build:gradle:4.1.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }

Smartphone / tablet

• Device: Samsung Galaxy A10
• OS: Android 10
• Package version: 1.0.2
• Flutter version 2.0.6

Is there any other implementation that I have missed?

[remonh87]

Do you get a stacktrace in the logcat output?

Maybe 2 other things to check:

• Can you try to upgrade to flutter version 2.2.2 ?I do not think the last will solve it but doesn't hurt to try it out.
• Also make sure the following is in your manifest:

 <meta-data
            android:name="flutterEmbedding"
            android:value="2" />

[coder-Aayush]

@remonh87 I have migrated flutter version 2.2.2 and the issue still arises.
here is the error

I too have this issue.

[jonasbark]

Does this happen to you on the example app from this repository as well?
Can you share a small project where this issue is reproducible?

[JoyEnergiser]

So when I created an app from scratch and plugged everything in as an example to show you it worked fine and created the transaction in the stripe log, sigh. So there is something within my main app that is causing this. Will continue investigating.

I managed to reproduce the error
If you change the src/main/AndroidManifest.xml

android:name=".MainActivity" (This is the default when you create a new project)
to
android:name="io.flutter.embedding.android.FlutterActivity" (this is how it is on my app that was created a while ago)

unfortunately it instantly crashes at runtime when i try to change my one to .MainActivity so no luck there

[jonasbark]

as the error states your MainActivity class must extend from FlutterFragmentActivity. In the github project link you shared it still extended from FlutterActivity.

Hi yea sorry I deleted that comment after I realised my mistake.That example worked when I changed that FlutterFragmentActivity

[subhra9326]

Hi I am getting same error but I have changed that in FlutterFragmentActivity. Please see the bellow I have given everything what I have implemented.

@subhra9326
android:name="io.flutter.app.FlutterApplication"
this should point to your MainActivity class instead

[subhra9326]

Hi, @jonasbark can you tell me the step to do that. I don't understand what to do. Thank you.

[JoyEnergiser]

Good day, I have solved my issue by editing my AndroidManifest.xml

1. adding the following android:name=".MainActivity" instead of android:name="io.flutter.embedding.android.FlutterActivity"
2. removing
   meta-data
   android:name="io.flutter.app.android.SplashScreenUntilFirstFrame"
   android:value="true"

I found the solution here since it was crashing on runtime flutter/flutter#47136

[subhra9326]

Hi, @JoyEnergiser and @jonasbark, thanks for helping me, My problem is resolved. Again thanks a lot.

I guess so... now i have another error but i think its not related with the package.

Thanks!

[xlcod]

io.flutter.embedding.android.FlutterFragmentActivity

I tried writting that, it doesn´t show any errors but also it doesn´t show any google pay button in my case.

[jonasbark]

that would be another configuration issue, unrelated to this topic. Be sure to check out official stripe documentation around Google Pay + Payment Sheet which you're using I guess.

[harguilar]

hey @remonh87 thanks a lot my issue is fixed

[kylegraycar]

I had this issue too and was able to fix once I realized I needed to add FlutterFragementActivity to the right MainActivity.kt.

My app, decarbon, had the file for both:
com.example.decarbon >>>> Updating this fixed the issue for me, I think because it's the one that my AndroidManifest.xml points to...
and
com.decarbonapp.decarbon.dcrbn3
within .../android/app/src/main/kotlin/com

How do i get over this problem now??

[mohaneesh-03]

How can I provide you with an example app?

[remonh87]

would be great if you can create a GitHub repo with an example app where we can try to reproduce the issue

[mohaneesh-03]

@remonh87 here is the link to the example app repo
https://github.com/mohaneesh-03/stripe_example.git

[remonh87]

@mohaneesh-03 your app it works without any problems for me. Probably you need to do a flutter clean and then build it again

[mohaneesh-03]

@remonh87 I did the flutter clean command and rebuild my project. But now it's giving me this error

Please help me.
