@VictorUvarov Can you confirm if the build successful after including this?

[VictorUvarov]

The build is not successful after adding the dependency as an implementation

[AbdullahChauhan]

Ok. Any other solution you found regarding this?

@computerfriendlog2 You need to migrate to JDK 17.

I'm running into the same issue as well
Any solution? @AbdullahChauhan @VictorUvarov

You can try adding

        minifyEnabled false
        shrinkResources false

to your release buildtype in gradle. Not smart for production builds since it'll disable obfuscation, but good enough for just the example app.

It does get the build to work, but like you said, not very ideal for a production build...

[mcmikashi]

Don't know if this good practice, but I add this on android/app/build.gradle:

`    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
        }
    }`

and add android/app/proguard-rules.pro with this :

`# Please add these rules to your existing keep rules in order to suppress warnings.
# This is generated automatically by the Android Gradle plugin.
-dontwarn com.google.android.gms.tapandpay.TapAndPayClient
`

@remonh87 Any ideas?

[remonh87]

add the following to your proguard files solves the issue. will document this in the troubleshoot settings of the app + readme

-dontwarn com.stripe.android.pushProvisioning.PushProvisioningActivity$g
-dontwarn com.stripe.android.pushProvisioning.PushProvisioningActivityStarter$Args
-dontwarn com.stripe.android.pushProvisioning.PushProvisioningActivityStarter$Error
-dontwarn com.stripe.android.pushProvisioning.PushProvisioningActivityStarter
-dontwarn com.stripe.android.pushProvisioning.PushProvisioningEphemeralKeyProvider
