Could be nice to fix this two hints:

• Missing PendingIntent mutability flag (Line 67)
• Missing PendingIntent mutability flag (Line 132)

[AenBleidd]

We support Android versions starting from Android 4.1 (API level 16).
If this set, this will not work for any that is older than Android 6.0 (API level 23).
So you should either find a way to fix that warning without increasing making ANdroid 6.0 as a minimal supported version or just rollback and leave it as-is (the first in preferred).

I can add the below code, but a deprecated warning won't go away
contentIntent = if (VERSION.SDK_INT >= VERSION_CODES.M) { PendingIntent.getActivity(context, 0, intent,PendingIntent.FLAG_IMMUTABLE or PendingIntent.FLAG_UPDATE_CURRENT) } else { PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT) }

Then just rollback your last commit and it should be ok

And add this annotation at the top of this class:

@SuppressLint("UnspecifiedImmutableFlag")
