Android Recycle View LogCat: could not find method

Question

I have a RecyclerView from the Android Support Library. When you work on Samsung Galaxy S2 with Android 4.1.2 (API 16), everything works fine, but in Logcat I see messages:

03-24 I/dalvikvm: DexOpt: illegal method access (call Landroid/support/v7/widget/RecyclerView$ViewHolder;.isUpdated ()Z from Lnet/mytest/TransactionsAdapter$TransactionsAdapterViewHolder;) 03-24

Should I worry about this post?

Answer 1

Have a look at this answer fooobar.com/questions/175899 / ...

Basically, you are not calling the correct method. You will need to call the appropriate support method.

eg. calling getActionBar () from v14 instead of getSupportActionBar () from v7 will cause this problem.

Make sure you call support methods and this error will disappear.
