openCardReaderPage is empty and I get no error

[Henner]

Hi,

my card reader page is empty (blank white screen) after calling: SumUpAPI.openCardReaderPage(MainActivity.this, 4);

experianced on SUNMI T2s

I reflected the following settings:

implementation "com.google.android.gms:play-services-location:19.0.1" coreLibraryDesugaring "com.android.tools:desugar_jdk_libs:1.1.5" implementation 'com.sumup:merchant-sdk:4.2.0'

android { compileOptions { coreLibraryDesugaringEnabled true } }

The SumUp App from the Appstore runs fine on this device.

All I get is: (SumUpButtonBase.kt:44)@main | Button text cannot exceed 20 characters

I was missing:

I only had:

<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />

Hi @Henner,

I have the same problem. What was the problem here?

Thanks!

[Henner]

this is still unresolved!

I do have this problem on several accounts - but not on all. My error message is: (SumUpButtonBase.kt:44)@main | Button text cannot exceed 20 characters

Creating a new account did solve this 2 times. I have no answer from integration@sumup.com

What is your error?

still unresolved

It is the same error for me and I also tried different accounts, not all accounts have this problem. At the first point I though this is a problem related to integration but it seems it is account related thing.
