I have read question with similar titles already.
Like you can see there is not much info.
I have checked in the R file there is no 0x00000021c resource.
This happens when I press a button and I am creating a new Intent and I want to load a new Activity to the screen. It is like a "Next screen" button...
The new activity is big, and right now I am splitting the dynamic and the static parts: a lot of xml-s, and not a simple one with 1-2 view. Around total 100 view?
As I saw the other questions and answers I think I have somewhere a .setText("Some invalid stuff here")
Any idea how to find that line, except with debugger step by step over thousand of lines?
