I am developing a mobile app for a company and we are using paypal. In the sandbox environment I have a test account that I am using for test transactions but it keeps giving me this error.

The credentials ( email and password) are directly from the dashboard.

The error is: 

E/paypal.sdk: request failure with http statusCode:404,exception:Not Found
E/paypal.sdk: Exception parsing server response

In addition when I try paying with a test card it gives me this:

We've confirmed the email yesterday.

And when I try linking  the test accounts it gives me this message:

Something went wrong. Your sandbox account could not be linked to your developer account. Try again.

Hello,

The android mobile SDK is depreciated and not recommended for new integrations.

Use one of our checkout SDK instead :

Thanks !
