@vivekshindhe @vivekagarwal1984 @sumedht Please help.

[vivekshindhe]

@ravisharma46 not able to reproduce this on our end. Please ensure the following points are ticked from your side,

• You are using custom checkout version 3.9.3.
• You have added pro guard rules mentioned in the document. Adding them here for ease of use,

-keepclassmembers class * { @android.webkit.JavascriptInterface ; }

-keepattributes JavascriptInterface -keepattributes Annotation

-dontwarn com.razorpay. -keep class com.razorpay. {*;}

-optimizations !method/inlining/*

-keepclasseswithmembers class { public void onPayment(...); }

Please check if these are true. This should solve the issue.

[ravisharma46]

Yes i am using the same in my proguard file

-keepclassmembers class * { @android.webkit.JavascriptInterface ; }

-keepattributes JavascriptInterface -keepattributes Annotation

-dontwarn com.razorpay. -keep class com.razorpay. {*;}

-optimizations !method/inlining/*

-keepclasseswithmembers class { public void onPayment(...); }

@vivekshindhe Please check this out

[vivekshindhe]

How are you generating your release build?

[ravisharma46]

@vivekshindhe I am generating signed APK threw android studio

[vivekshindhe]

@ravisharma46 What payment are you attempting? At what stage does this happen? A video would be helpful too. Also, I've updated this git repo with branch v3.9.3. This has my implementation of this, and a release build with custom-checkout v3.9.3. Could you please also try that?

After clicking on buy button a checkout page should be open but i am getting crash on buy now button click. Please find the video i have shared link @vivekshindhe

[vivekshindhe]

@ravisharma46 You are using custom checkout right? There won't be a checkout page. I didn't understand that part. Could you please clarify?

[ravisharma46]

@vivekshindhe yes i am using custom check out page.

razorpay = new Razorpay(this, Constants.RAZORPAY_KEY); razorpay.getPaymentMethods(new PaymentMethodsCallback() { @Override public void onPaymentMethodsReceived(String result) { inflateLists(result); }

        @Override
        public void onError(String s) {
            FirebaseCrashlytics.getInstance().recordException(new Exception("Reading Payments methods  " + s));
        }
    });

Here is the code in my payment activity..I am getting crash when i am fetching all payment methods. the crash i have shared in first comment.

Would it be possible for you to share the build you are testing this on? You can also share it to my mail, vivek.shindhe@razorpay.com. If possible. Or you could manually check for the existence of the class com.razorpay.K by analysing the apk. If it doesn't exist this will have something to do with proguard.

[ravisharma46]

ok i am sharing you a release build on your mail.

[ravisharma46]

@vivekshindhe have shared APK on your email.

[vivekshindhe]

I can see the file. Will need to deep dive on this. Until then please check the branch v3.9.3 in the repo.

[ravisharma46]

@vivekshindhe keeping this in release build mode it is working. could you please check. release { debuggable true FirebasePerformance { instrumentationEnabled false } }

[vivekshindhe]

@ravisharma46 thanks for update. Do you use R8? Also if possible can you add -dontusemixedcaseclassnames to your proguard? This seems to be an issue due to Firebaseperformance doing the obfuscation. Here's the github ticket on the issue from firebase repo https://github.com/firebase/firebase-android-sdk/issues/1476#issuecomment-625177988. Please let me know if this works.

[ravisharma46]

I have to update the firebase performance plugin. Now, it is working very fine.

Thank you very much for the fast response @vivekshindhe

[vivekshindhe]

@ravisharma46 awesome news. Thanks for reaching out to us. Closing the ticket now.
