title: No package identifier when getting value for resource number
body: <p>I have read question with similar titles already.
  <img src="https://i.stack.imgur.com/fp9LR.png" alt="enter image description here"></p>
  
  <p>Like you can see there is not much info.</p>
  
  <p>I have checked in the R file there is no 0x00000021c resource.</p>
  
  <p>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...</p>
  
  <p>The new <strong>activity is big</strong>, 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?</p>
  
  <p>As I saw the other questions and answers I think I have somewhere a .setText("Some invalid stuff here")</p>
  
  <p><strong>Any idea how to find that line, except with debugger step by step over thousand of lines?</strong></p>
