Unable to use the Accessory SDK

Mobile
1

I’m trying to integrate the Accessory SDK into a library, but trying to compile a project using said library throws an error.
After a bit of research, it seems like the Accessory SDK is being compiled against an old version of Java, and isn’t compatible with the new verification scheme found in Java 1.7 and up.

Error here:

Hello,
If your App targets Android R(30) and interacts with other apps which is installed on the same device, you need to use the element in the Manifest file so that system knows which other apps to show to your app.

Kindly include the below piece of code in the manifest file.

<manifest package="com.your.app.package">
 <queries>
 <package android:name="com.samsung.accessory" />
 </queries>
    ...
</manifest>

For more details, please visit the below link

Yes I’m aware of the package query limitations, and I already have that code in my manifest.
The issue stems from me targeting Java 1.8, and the library is compiled with a version that’s either 1.6 or lower. As of Java 1.7, bytecode verification changed slightly, which causes the failing check.
The workaround now is to pass “-noverify” in for the JVM args, but this still isn’t great and you still need to resolve the underlying issue.

Nowhere did I mention I’m targeting Android SDK 30 (which I am), so while I appreciate you taking the time to leave a detailed answer, please read the question before answering next time.
