    <p>The ADB binary at

  <p>I tried to check at: SDK Manager -> SDK Tools -> Android SDK Build-Tools (<a href="https://stackoverflow.com/a/51549901/12700911">link to that answer</a>). But the last update has been installed already.</p>
  
  <p>P.S. I know, such a question already exists (<a href="https://stackoverflow.com/questions/51240223/adb-exe-is-obsolete-and-has-serious-performance-problems">link to that question</a>), but there I can't write a solution that helped me, because I don't have enough reputation points. So, I'll write here the solution, maybe it will help someone...</p>
