The application crashes on Android 6 (JDK 17) when launched

[alexbayker]

The application crashes on Android 6 (JDK 17) when launched due to the library com.fasterxml.jackson.core:jackson , which in versions higher than 4.13.5 throws Exception java.lang.NoClassDefFoundError: Failed resolution of: Ljava/lang/BootstrapMethodError; . Similar problem is described here: square/retrofit#4131

Because of this, I cannot update your library to a version higher than 5.4.6, since it uses the Jackson library version 4.15.0

Hi @alexbayker,

Thanks for the report! We're investigating this issue. We'll follow up here once we have an update.

Hi @alexbayker,

I just wanted to follow up to let you know that there are no plans to support SDK levels as low as Android 6.

Currently, Android 6 accounts for just 1.19% of the global usage base, which makes it difficult to justify the ongoing maintenance and support costs. To keep the project efficient and aligned with the majority of users, we’ve chosen to focus on more recent versions of Android.

We really appreciate your understanding!

The problem is that at the moment android 6 is supported by minsdk, but in fact the library does not work there, and in addition, it breaks the application where this library is imported.

We use Dropbox storage for backups on payment terminals, where the share of devices on old versions of Android is quite high, so we really need this library. We can't use the old Dropbox library in our project, because there is a problem with SSL certificates

Hi @alexbayker, I appreciate providing additional context. I will pass the information along to the team.

The problem is solved as follows:
implementation ("com.dropbox.core:dropbox-android-sdk:$versionDropbox") { exclude group: 'com.fasterxml.jackson.core', module: 'jackson-core' exclude group: 'com.fasterxml.jackson.core', module: 'jackson-annotations' exclude group: 'com.fasterxml.jackson.core', module: 'jackson-databind' exclude module: 'com.fasterxml.jackson.module' }
