When trying to implement the Lollipop Palette.GenerateAsync to get colors from a Bitmap, I'm getting the following error:
Java.Lang.NoClassDefFoundError: Failed resolution of: Landroid/support/v4/os/AsyncTaskCompat;
This error breaks my app. The complete error log is in the attachment.
@Bill: Landroid/support/v4/os/AsyncTaskCompat; is a Support type; is it being included into the .apk?
The Support-v7-Palette nuget package did not have a dependency on Support-v4 which it should have (to prevent this error).
This has been corrected and will be included in the v22.214.171.124 nuget release of Support-v7-Palette. In the meantime you could reference support-v4 in your project manually, or simply use the non-async Generate () method (perhaps run it in a Task for a similar result).
