Crash apk error

[Juniornewxt]

Hello friend, you did a great job, but I can't test the apk, it closes by itself on my galaxy s21, I downloaded the code and compiled it on my PC and got the same problem of closing by itself.

Dear Juniornewxt,
Thanks for informing me about an issue you have with the app. As the app and it's tutorial is popular on medium.com and I never got informed about any problems I have to assume that the problem is related to your hardware.

B.t.w., please use the source in this repository for your work as this is the latest release of the app:

https://github.com/AndroidCrypto/TalkToYourCreditCardPart7

The tutorial series is starting here https://medium.com/@androidcrypto/talk-to-your-credit-card-android-nfc-java-d782ff19fc4a

Regarding your problem: have you tried to compile the very first (base) app of the article series located here ?:

As I'm not using "heavy" dependencies within my app there seems to one specific that doesn't work with your hardware, sorry for that.

Greetings,
Michael
